What does sharemarket turmoil tell us about our economy? Not a lot

 

By MILLIE MUROI, Economics Writer

When the Reserve Bank board walked into their two-day interest rate meeting in Sydney this week, most of their key numbers were locked in.

By the time they closed their laptops and zipped up their bags on Monday, the Australian sharemarket had shed close to $100 billion in one day: the biggest single-day drop since the pandemic came knocking. The Reserve Bank board “discussed it, obviously,” governor Michele Bullock told the media on Tuesday, but the turmoil didn’t play a role in the bank’s final decision to keep interest rates on hold.

So why didn’t the central bank care when panic swept across financial markets earlier this week? In short: because the sharemarket isn’t the economy – or a good indication of it. “It was a bit of an overreaction,” Bullock said. “It was one number.”

That number – a jump in the US unemployment rate – rattled investors because it signalled the world’s biggest economy could be closer to recession than people had thought. But why did it hit the Australian sharemarket so hard? And what does it tell us about our economy, if anything?

First, volatility in financial markets – where people buy and sell financial assets – doesn’t necessarily relate to the “real economy” with its goods, services and people. “Financial volatility does affect sentiment, and incentives for households and businesses to invest,” Bullock said at an address in her hometown of Armidale on Thursday. “But it isn’t the economy.”

Second, financial markets around the world have become increasingly intertwined. When something happens, especially in US markets, it’s certain to have a knock-on effect for Australia. And with so many large investors holding similar views, there was probably a “mechanical response” by markets, according to Westpac chief economist, and former RBA chief economist, Luci Ellis.

By that, she means a lot of people’s investment strategies changing course at the same time. “If large parts of financial market investors change their mind about the outlook for interest rates in the US, for example, they’ll all be trying to do the same thing at once,” she says.

There’s also a thing called “herd mentality bias” in finance, which refers to investors’ tendency to follow and copy what other investors are doing. A rhetorical question most of us get asked when we’re young and want to do something because our friends are, is: “if your friend jumped off a cliff, would you do the same?” When it comes to the sharemarket, the answer is often yes.

But this means when the tide starts to turn, there’s often a big shift in markets, with people hopping onto (or off) the bandwagon and copying what their peers are doing. As share prices start to fall, often the panic feeds on itself, and manifests in a big stock-selling frenzy, regardless of what started it.

It’s hard to pinpoint exactly what markets were thinking, and what factors fed into their reaction earlier this week. But the clear feeling sweeping through it was nervousness. When investors are nervous, they tend to sell shares, and move into “safer” investments such as bonds.

Does all this mean the Australian economy is in for an apocalypse? No, far from it.

When it comes to the fallout of the sharemarket plunge, there will probably be a slight impact on people’s wealth, at least over the short term, in what’s called the “wealth effect”. This is essentially the theory that people will tend to spend less when the value of their assets – such as their investments in the sharemarket – fall, and vice versa. The richer we feel, the more we’re likely to splurge.

But most Australian households don’t think too deeply about day-to-day movements in the sharemarket. A lot of our wealth, particularly when it comes to shares, are held in our superannuation funds, which most of us check on about as often as we change our tyres – only when we need to. And while the plummet this week may have caught our attention, we’re likely to have largely forgotten about it a few months down the line.

HSBC Australia chief economist Paul Bloxham points out it wasn’t just one number driving the movement.

On top of the weaker-than-expected jobs data from the US, there was also weaker manufacturing sentiment and Japan’s decision to hike interest rates, he says. Investors have been making the most of near-zero interest rates in Japan by borrowing money to invest in other countries such as the US: a strategy known as a “carry trade”. But the deadly combination of rising interest rates in Japan and signs of a slowing economy in the US suddenly made this trade unattractive, leading to a rapid pullback from these types of investments.

“When markets have a lot of participants all holding the same view, and it turns out that view isn’t right, when all of those people try to get out of that trade all at once, it can often be quite difficult, and you get more volatility,” he says.

While the Australian economy is closely connected to other countries, especially those in Asia, the choppy forces moving the Australian sharemarket often tend to be global.

By contrast, Bloxham says the biggest issue for the Australian economy remains inflation, which has become an increasing domestic issue.

“What matters more right now is that local inflation is still higher than it should be,” he says. “That matters more in terms of thinking about interest rates, and what it means for the local economy more generally, and that’s why the RBA is more focused on that than they are on the share market turmoil we’ve seen.”

To be clear, financial market movements can influence economic policy decisions from the RBA and the government, especially if they suggest there are problems around financial stability. During the global financial crisis, for example, the sharemarket crash reflected big losses in wealth and large numbers of people becoming financially distressed, which had a significant impact on the economic outlook. And a sluggish US economy would undoubtedly drag down overall global growth.

But sharemarket scares are frequent. And while the financial market, with all its fancy instruments can, on rare occasions, reflect the health of the economy, more often than not, it’s much ado about nothing. Don’t read too much into it.

We should stop using a blunt instrument to manage the economy

In the economy, as in life, it helps a lot if you learn from your mistakes. Or, if you’re in public life, from the mistakes of your predecessors.

Accordingly, the caning that former Reserve Bank governor Dr Philip Lowe got for his assurance that interest rates wouldn’t rise before 2024 does much to explain why his successor, Michele Bullock, has been so persistently cagey about the future of rates.

Even as she’s announced a decision that the official cash rate was to be left unchanged, she’s warned that it may need to rise in future. And indeed, that the case for raising it had been seriously considered.

But last week, with the herd sniffing in the wind the smell of rate cuts, she took her life in her hands and got a lot more specific – though not before muttering the incantation that she was not providing “forward guidance” (that was the crime Lowe was convicted of).

In a carefully rehearsed line, she said that a “near-term reduction in the cash rate does not align with the board’s current thinking”. Oh yes, and what does “near term” mean? The next six months, she said.

“Current” thinking. Get it? In other words, that thinking could change over, say, the next six months. Especially because, as she repeated, the board’s decisions would depend on what the economic indicators were telling it. And, as she keeps saying, “the outlook remains highly uncertain”.

It’s clear many people aren’t convinced the board’s thinking against cutting rates will stay unchanged for the next six months. Because the financial markets are so heavily into betting, their predictions are almost always based on what they expect the Reserve will do.

But there are plenty of other, simpler souls, whose emphasis is on what they believe the Reserve should do to ensure it avoids the recession it says it wants to avoid.

The other point about learning from your mistakes and adventures is the familiar problem that those who were around at the time of lesson-learning pass on, handing over to people who weren’t around to have learnt.

This is what worries me as the Reserve ploughs on, determined to ensure the inflation rate returns to the centre of its target range within a time that the Reserve itself judges to be the maximum time acceptable. This determination seems to be regardless of the source of the forces that are slowing the return to mid-target and making it “bumpy”.

When the Reserve was granted operational independence by the elected government in the mid-1990s, its bosses at the time understood a truth I’m not sure their successors still understand. When you’re not free of the politicians, you can leave the politics to them. But when you are free of them, you have to do your own politics.

Now, I’ve been a great supporter of central bank independence. It’s been one experiment that time has shown to be a big improvement on leaving interest rates to the pollies. But we, and the central bankers, must understand that central bank independence is an uneasy fit with democracy.

We now have a situation where the central bank has the most control over whether the economy is plunged into severe recession, but the only people the voters can punish for this are not the central bankers, but the government of the day.

So, to get specific, if the Reserve Bank decides inflation can’t be fixed without a recession or, more likely, miscalculates and leaves interest rates too high for too long, it won’t be Michele Bullock that voters punish, it will be Anthony Albanese and his government.

Guess what? Should that happen, Labor is likely to be angry and vengeful. And, as Bullock’s predecessors understood, should government pass to the Liberals, their strongest emotion is likely not to be gratitude, but a determination that the Reserve won’t be allowed to trip them up the way it tripped up Labor.

With independent central banks being the long-established convention throughout the developed world, would any government of ours be game to strip the Reserve of its independence? Probably not.

But politicians have other, less noticeable ways of bringing independent institutions to heel. The usual way – practised by the previous federal government with the Administrative Appeals Tribunal and the Fair Work Commission, and by Donald Trump with the US Supreme Court – is to stack appointments to the board with people who share the government’s predispositions.

So there will be a way for the politicians to pass the voters’ punishment on to the Reserve should it stuff up. This is why it does have to do its own politics.

And there’s another, far more positive way that could be used to clip the Reserve’s wings. This episode of tightening, much more than any previous episode since the day-to-day management of the macroeconomy was handed over to the Reserve in the 1980s, has revealed just how unfair and ineffective it is to make the manipulation of interest rates the dominant instrument for managing the strength of demand.

As research by Associate Professor Ben Phillips of the Australian National University has confirmed, the much-lamented cost-of-living crisis has been imposed on households with big mortgages far more than on any other households.

When you take account of the way rents actually fell during the lockdowns, renters haven’t been hard hit, while those who own their homes outright have been laughing. People on pensions or the dole have been protected by indexation.

So the reliance on interest rates to reduce demand is hugely unfair. But it’s also lacking in effectiveness. All of us have contributed to the excessive demand for goods and services, but only the minority of us with big mortgages have been pressed directly to pull back our spending.

This is why our management of the macroeconomy needs reform. We need another, much broader-based instrument that could be used as well as, or in place of, interest rates. Temporary changes in the rate of the goods and services tax are one possibility, but I’m attracted to the idea of temporary changes to the rate of compulsory superannuation contributions.

The two instruments – one interest rates, and the other budgetary – could be controlled by a new independent authority.

Despite all the Reserve’s apologies for having just a single, blunt tool and all the hardship it causes home buyers, we’ll wait a long time before it suggests sharing its power with a rival independent authority.

As well, the banks have ways of ensuring they benefit from rising interest rates, while financial markets want to keep betting at Reserve Bank race days.

So I’m tempted by the thought that only if the Reserve stuffs up and causes a severe recession are we likely to see the reform to macroeconomic management we so badly need.

There's a good case for cutting interest rates ASAP

What a difference a number makes. For weeks, the money market’s macho men had been telling us interest rates needed to rise yet further to ensure inflation would keep falling. But last week, their case went up in smoke and now almost no one thinks the Reserve Bank board will do anything at its two-day meeting starting today.

The weeks of idle speculation came to an end when finally we saw the consumer price index for the June quarter. It showed underlying inflation falling to 3.9 per cent.

So, sighs of relief all round. But why had we allowed these misguided souls to cause us so much angst? Why had their intimations of death and destruction been given so much air time?

Short answer: because we find bad news more interesting than good news. But as last week’s abrupt turnaround reminds us, the bad news ain’t necessarily so. So maybe we should give a hearing to those urging the Reserve to do something nice rather than nasty.

Let me tell you about a briefing note from the economists at the Australian Council of Social Service, who remind the Reserve that its much-remarked “narrow path” to lower inflation without triggering a recession and high unemployment is narrow “because it’s rare for interest rate hikes of this scale and intensity not to trigger a serious economic downturn”.

The peak welfare organisation says the process of reducing demand and lowering inflation is already well under way and, since increases in official interest rates take up to two years to flow through to inflation and unemployment, it has called for the Reserve to start reducing interest rates immediately.

Those who focus on the slowdown in the fall of the inflation rate and conclude there’s a need for further tightening have failed to see how sharply job opportunities and living standards have fallen, even without a recession.

The council examines the data for the two years since the Reserve began increasing interest rates, from June 2022 to June 2024, and it finds a lot more evidence of downturn and pain than you may realise.

For a start, the number of vacancies for entry-level jobs has declined by almost a third. There are an additional 100,000 people unemployed, and almost as many extra people suffering underemployment (unable to find as many hours of work as they want).

If you know employment is still growing, get this: this has occurred only because of stronger growth in publicly funded jobs (particularly under the National Disability Insurance Scheme). The annual number of publicly funded jobs has grown from 210,000 to 326,000, whereas jobs growth in the market sector has collapsed from 321,000 a year to 6000 a year.

If interest rates stay high, jobs in the market sector are likely to decline, but the present growth in publicly funded jobs won’t last.

We have avoided a recession – an economy that’s getting smaller – so far only because of the surprisingly strong bounce-back in immigration since the reopening of our borders. This won’t continue.

But the real value of goods and services produced per person has been falling, meaning that living standards have been falling. Over the two years, average real income per person has fallen by 8 per cent, or about $5000 a year.

According to the council’s calculations, the stage 3 tax cuts, the energy rebate and increased rent allowance for people on pensions or benefits announced in the May budget will restore only about a fifth of this loss of real income to households.

So the macho men’s fear that the budget measures will add to inflation pressure is laughable. And the council doesn’t miss the opportunity to remind us that JobSeeker unemployment benefits remain a miserly $55 a day.

As for the macho men’s fear that a “price-wage spiral” could take off at any moment, the council says average wages have fallen by 2 per cent since June 2022, after adjusting for inflation.

Wages have started rising a fraction faster than inflation, but it will take many moons to make up that gap. Meanwhile, the collapse in consumer spending has been “precipitous”: a fall of 10 per cent in real spending per person since June 2022.

If the Reserve’s renewed commitment to maintaining full employment is to have any meaning, it will need to start cutting the official interest rate ASAP.

It's slowing the spin doctors' spin that keeps me busy

Do you remember former prime minister John Howard’s ringing declaration that “we will decide who comes to this country and the circumstances in which they come”? It played a big part in helping him win the 2001 federal election. But it’s only true in part.

The job of economic commentators like me is supposed to be telling people about what’s happening in the economy and adding to readers’ understanding of how the economy works.

But the more our politicians rely on spin doctors to manipulate the media and give voters a version of the truth designed always to portray the boss in the most favourable light, the more time I have to spend making sure our readers aren’t being misled by some pollie’s silken words.

These days, I even have to make sure our readers aren’t being led astray by the economics profession. For the first time in many years, I’ve found myself explaining to critical academic economists that I’m a member of the journos’ union, not the economists’ union.

Like many professions, economists are hugely defensive. And they like to imagine my job is to help defend the profession against its many critics. Sorry, I’m one of the critics.

My job is to advise this masthead’s readers on how much of what economists say they should believe, and how much they should question.

It’s not that economists are deliberately misleading, more that they like to skirt around the parts of their belief system that ordinary people find hard to swallow.

And then there’s the increasing tendency for news outlets to pick sides between the two big parties, and adjust their reporting accordingly. My job is to live up this masthead’s motto: Independent. Always.

So, back to Howard’s heroic pronouncement. It’s certainly true that “we” – the federal government – decide the circumstances in which people may come to Australia. If you turn up without a visa, you’ll be turned away no matter how desperate your circumstances. If you come by boat, your chances of being let in are low.

But if you come by plane, with a visa that says you’ll be studying something at some dodgy private college when, in truth, you’re just after a job in a rich country, in you come. If we’ve known about this dodge, it’s only in the past few weeks that we’ve decided to stop it.

No, the problem is, if you take Howard’s defiant statement to mean that we control how many people come to this country, then that’s not true. We decide the kinds of people we’ll accept, but not how many.

There are no caps because, for many years, both parties have believed in taking as many suitable immigrants as possible. It’s just because the post-COVID surge in immigration – particularly overseas students – has coincided with the coming federal election that the pollies are suddenly talking about limiting student visas.

But remember, the politicians have form. Knowing many voters have reservations about immigration, they talk tough on immigration during election campaigns, but go soft once our attention has moved on, and it’s all got too hard.

It’s a similar thing with Anthony Albanese’s Future Made in Australia plan. Polling shows it’s been hugely popular with voters. But that’s because they’ve been misled by a clever slogan. It was designed to imply a return to the days when we tried to make for ourselves all the manufactured goods we needed.

But, as I’ve written, deep in last month’s budget papers was the news that we’d be doing a bit of that, but not much. It’s just a great slogan.

On another matter, have you noticed Treasurer Jim Chalmers’ dissembling on how he feels our pain from the cost-of-living crisis, which is why he’s trying so hard to get inflation down?

What he doesn’t want us thinking about is that, at this stage, most of the pain people are feeling is coming not from higher prices, but from the Reserve Bank’s 4.25 percentage-point increase in interest rates.

Get it? The pain’s coming from the cure, not the disease. The rise in interest rates has been brought about by the independent central bank, not the elected government, of course. But when Chalmers boasts about achieving two successive years of budget surplus, he’s hoping you won’t realise that those surpluses are adding to the pain households are suffering, particularly from the increase in bracket creep.

And, while I’m at it, many people object to businesses raising their prices simply because they can, not because their costs have increased. This they refer to disapprovingly as “gouging”.

But few economists would use that word. Why not? Because they believe it’s right and proper for businesses to charge as much as they can get away with.

Why? Because they think it’s part of the way that market forces automatically correct a situation where the demand for some item exceeds its supply. In textbooks, it’s called “rationing by price”.

Rather than the seller allowing themselves to run out of an item, they sell what’s left to the highest bidders. What could be better than that?

Budget's message: maybe we'll pull off the softest of soft landings

When normal people think about the economy, most think about the trouble they’re having with the cost of living. But when economists think about it, what surprises them is how well the economy’s travelling.

It’s been going through huge ups and downs since COVID arrived in early 2020. By 2022, it was booming and the rate of unemployment had fallen to 3.5 per cent, its lowest in almost 50 years. Meaning we’d returned to full employment for the first time in five decades.

Trouble was, like the other rich economies, prices had begun shooting up. The annual rate of inflation reached a peak of almost 8 per cent by the end of 2022.

The managers of the economy know what to do when the economy’s growing too fast and inflation’s too high. The central bank increases interest rates to squeeze households’ cash flows and discourage them from spending so much.

The Reserve Bank started raising the official “cash” interest rate in May 2022, just before the federal election. It kept on raising rates and, by November last year, had increased the cash rate 13 times, taking it from 0.1 per cent to 4.35 per cent.

While this was happening, Treasurer Jim Chalmers was using his budget – known to economists as “fiscal policy” – to help the Reserve’s “monetary policy” to increase the squeeze on households’ own budgets, reducing their demand for goods and services.

Why? Because, when businesses’ sales are booming, they take the chance to whack up their prices. When their sales aren’t all that brisk, they’re much less keen to try it on.

The government’s tax collections have been growing strongly because many more people had jobs, or moved from part-time to full-time, and because higher inflation meant workers were getting bigger pay rises.

As well, iron ore prices stayed high, meaning our mining companies paid more tax than expected.

Chalmers tried hard to “bank” – avoid spending – all the extra revenue. So, whereas his budget ran a deficit of $32 billion in the year to June 2022, in the following year it switched to a surplus of $22 billion, and in the year that ends next month, 2023-24, he’s expecting another surplus, this time of $9 billion.

So, for the last two years, Chalmers’ budget has been taking more money out of the economy in taxes than it’s been putting back in government spending, thus making it harder for households to keep spending.

Guess what? It’s working. Total spending by consumers hardly increased over the year to December 2023. And the rate of inflation has fallen to 3.6 per cent in the year to March. That’s getting a lot closer to the Reserve’s target of 2 to 3 per cent.

The Reserve’s rate rises have been the biggest and fastest we’ve seen. Wages haven’t risen as fast as prices have and, largely by coincidence, a shortage of rental accommodation has allowed big increases in rents.

And on top of all that you’ve got the budget’s switch from deficits to surpluses. Much of this has been caused by bracket creep – wage rises causing workers to pay a higher average rate of income tax, often because they’ve been pushed into a higher tax bracket.

Bracket creep is usually portrayed as a bad thing, but economists call it “fiscal drag” and think of it as good. It acts as one of the budget’s main “automatic stabilisers”, helping to slow the economy down when it’s growing too quickly and causing higher inflation.

The Reserve keeps saying it wants to get inflation back under control without causing a recession. But put together all these factors squeezing household budgets, and you see why people like me have worried that we might end up with a hard landing.

Which brings us to this week’s budget. The big news is that in the coming financial year the budget is expected swing from this year’s surplus of $9 billion to a deficit of $28 billion.

This is a turnaround of more than $37 billion, equivalent to a big 1.3 per cent of annual gross domestic product. So, whereas for the past two financial years the “stance” of fiscal policy has been “contractionary” (acting to slow the economy), it will now be quite strongly “expansionary” (acting to speed it up).

Some people who should know better have taken this turnaround to have been caused by a massive increase in government spending. They’ve forgotten that by far the biggest cause is the stage 3 tax cuts, which will reduce tax collections by $23 billion a year.

The same people worry that this switch in policy will cause the economy to grow strongly, stop the inflation rate continuing to fall and maybe start it rising again. But I think they’ve forgotten how weak the economy is, how much downward pressure is still in the system, and how long it takes for a change in the stance of policy to turn the economy around.

Treasury’s forecasts say the economy (real GDP) will have grown by only 1.75 per cent in the financial year just ending, will speed up only a little in the coming year and not get back to average growth of about 2.5 per cent until 2026-27.

So, the rate of inflation will continue falling and should be back into the target range by this December. All this would mean that, from its low of 3.5 per cent – which had risen to 4.1 per cent by last month – the rate of unemployment is predicted to go no higher than 4.5 per cent.

That would be lower than the 5.2 per cent it was before the pandemic, and a world away from the peak of about 11 per cent in our last big recession, in the early 1990s.

So maybe, just maybe, we’ll have fixed inflation and achieved the softest of soft landings. Treasury’s forecasting record is far from perfect, to put it politely, but it is looking possible – provided we don’t do something stupid.

With luck, we’ll escape recession next year, but it will feel like one

What we’ve come to call the “cost-of-living crisis” has made this an unusually tough year for many people as they struggle to make ends meet. It’s likely to get worse rather than better next year. Which won’t help Anthony Albanese’s chances of being comfortably returned to government in early 2025.

Everyone hates rapidly rising prices and demands the government do something. But I’m not sure everyone understands the paradoxical nature of the usual ways central banks and governments go about fixing the problem. They make it worse to make it make better.

In a market economy, when our demand for goods and services exceeds the economy’s ability to supply them, businesses solve the problem by putting up their prices. The economic managers then seek to weaken our demand by squeezing households’ finances so that they can’t spend as much.

As our spending weakens, firms are less able to keep raising their prices without losing sales.

The main way the Reserve Bank puts the squeeze on household spending is by engineering a rise in mortgage interest payments, leaving people with less money to spend on everything else.

A shortage of rental housing has allowed landlords to make big rent increases. Employers have helped the squeeze by ensuring they raise wages by less than they’ve raised their prices. And Treasurer Jim Chalmers has helped by allowing bracket creep to take a bigger tax bite out of wage increases.

All this is why so many people have been feeling the financial heat this year. But even if there are no more interest rate rises to come, the existing pressures are still working their way through the economy, with little sign of relief.

Consumer prices rose by 7.8 per cent over the year to last December, but the annual rate of increase slowed to 5.4 per cent in September. That’s still well above the Reserve’s target of 2 per cent to 3 per cent.

If the Reserve has accidentally hit the economy harder than intended, we could slip into recession next year, causing a big jump in the number of people out of a job, and thus hitting them much harder.

But with any luck, it won’t come to that. And the crazy-lazy way the media define recession – a fall in real gross domestic product in two successive quarters – means that growth in the population may conceal the hip-pocket pain many people are feeling.

Consider the case of someone on the very modest wage of $45,000 a year in September 2021. If their wage rose in line with the wage price index, it would have risen by $3300 to $48,300 in September this year.

However, bracket creep, plus the discontinuation of the low and middle income tax offset, raised the average rate of income tax they pay from 9.8¢ in the dollar to 14.2¢. So their tax bill would have grown by $2460.

Now allow for the rise in consumer prices over the two years, and the purchasing power of their disposable income has fallen by about $5290, meaning their “real” disposable income is $4450 a year less than it used to be.

Can you imagine that person being terribly happy with the way their finances have fared under the Albanese government? My guess is, there’ll be growing disaffection with Labor as next year progresses.

To help him win last year’s federal election, Albanese made Labor a “small target” by promising very little change, including no change to the stage three income tax cuts, legislated long before the pandemic, to start in July next year.

His game plan had been to spend his first term being steady and sensible, keeping his promises and being an “economically responsible” government. This would get him re-elected with an increased majority and able to implement needed but controversial reforms.

But, through no great fault of his own, he’s had to grapple with the worst surge in the cost of living in decades. If there’s a low-pain way to get inflation back under control, I’ve yet to hear about it.

The trouble set in well before the change of government, and the Reserve Bank began its long series of interest rate rises during the election campaign.

My guess is that Albanese’s hopes of storming back to power at an election due by May 2025 are dashed. But it’s hard to see Peter Dutton winning the election unless he can win back the Liberal heartland seats that went to the teals, which seems doubtful.

So, it’s not hard to see Albanese losing seats and reduced to minority government, dependent on the support of the Greens and teals.

There is, however, one thing he could do to cheer up many voters: rejig the coming tax cuts so the lion’s share of the $25 billion they’ll cost the budget goes not to the high-income taxpayers who’ve had the least trouble coping with living costs, but to those on lower incomes who’ve the most.

Why it's doubtful we need another interest rate rise

There’s nothing the media likes more than an interest rate rise on Melbourne Cup day. It’s surprising how often it’s happened, and many in the financial markets have convinced themselves that’s what we’ll get next Tuesday. And the good news is that, despite the radical reform of moving to a mere eight board meetings a year, the Reserve Bank has ensured that meetings on cup day will continue.

What I’m not sure of is whether, if we do get a rate rise next week, it will be happening by accident or design. In central banking, getting your timing right is just as important as it is in a comedy routine.

It was no surprise last week when new Reserve Bank governor Michele Bullock used her first big speech to make sure everyone noticed her bulging anti-inflation muscles. “There are risks that could see inflation return to target more slowly than currently forecast,” she warned.

“The board will not hesitate to raise the cash rate further if there is a material upward revision to the outlook for inflation,” she said. She added some qualifications but, predictably, neither the markets nor the media took much notice of them.

Any new governor would have said the same in their first speech. Trouble is, her tough statement about not being willing to return to the 2 to 3 per cent inflation target “more slowly than currently forecast” came just the day before publication of the consumer price index for the September quarter.

And while it showed the annual rate of inflation continuing to fall from its peak of 7.8 per cent at the end of last year to 5.4 per cent nine months later, it also showed the quarterly inflation figure rising from 0.8 per cent to 1.2 per cent.

This was 0.2 percentage points or so higher than the markets – and, they calculate, the Reserve – were expecting. Bingo! Rate rise a dead cert. All the big four banks are laying their bets accordingly.

But the main reason for the slightly higher number was a rise in petrol prices, which contributed 0.25 percentage points of the 1.2 per cent. This rise comes from insufficient supply: the higher world price of oil, forced up the OPEC oil cartel and others trying to increase the price by restricting their supply.

It does not come from excessive Australian demand – which is the one factor the Reserve can moderate by increasing interest rates. Similarly, the next-biggest price increases, for newly-built homes (imported building materials), rents (surge in immigration) and electricity (Ukraine war) aren’t caused by anything a rate rise can fix.

So I think the case for yet another rate rise is weak. As Bullock clearly demonstrated elsewhere in her speech, the Reserve’s single, crude instrument, raising interest rates, delivers most of its punishment to the quarter or so of households with big mortgages.

Too many of these people are really hurting, and the full hurt from rate rises already made has yet to be felt. The economy is slowing, consumer spending is hardly growing, real income per person is falling.

And, as Treasury secretary Dr Steven Kennedy noted in a speech last week, last financial year’s budget surplus of $22 billion shows the budget’s “automatic stabilisers” are working hard to help the Reserve restrain demand – a truth that’s been completely missing from the Reserve’s commentary. That’s gratitude for you.

But if, having thought hard about such a small change to the “outlook for inflation”, Bullock decides a further rate rise isn’t warranted, what are the money market punters (and I do mean people making bets) going to think, considering all her chest-beating? That she speaks big but carries a soft stick?

There are a few things she – and her urgers in the financial markets (most of whom have never in their lives had reason to worry about the cost of living) – need to remember.

First, at this late stage in the game, we really are into fine-tuning. And acting because a revised forecast means we’ll return to target later than we had expected suggests you’ve forgotten what every governor needs always to remember: as with all economists, the Reserve’s forecasts are more likely to be wrong than right.

They can be wrong by a lot or wrong by a little. Worst, they can prove too optimistic or too pessimistic. If your previous forecast was wrong, what makes you so sure your next one will be right? When it comes to forecasts, the person making the actual decisions needs to be the biggest sceptic.

Second, the Reserve’s previous forecast was for inflation to be back to the top of the target range by the first half of 2025. If its latest forecast pushes that out to the second half, what’s so terrible about that? How much extra pain for young people with huge mortgages does that justify?

Ah, says the Reserve, the reason we can’t wait too long to get inflation back to target is that, the longer we leave it, the greater the risk that business’ and workers’ expected rate of inflation rises above the target range.

If that happened, we’d need much higher interest rates and much more pain to get expectations back down to the only range we’ve decided is acceptable.

This is true in principle but, in practice, it’s mere speculation. The fact is, the world’s central bankers have no hard evidence on how long it takes for inflation expectations to adjust – a few years or a few decades.

I’m old enough to remember that when inflation returned, in the late-1960s and early-’70s, it took a decade or two for expectations to adjust. The smarties used to advise youngsters to borrow as much as anyone would lend them. Why? Because real interest rates were negative.

But when a decade or two of tough inflation fighting eventually got expectations down to what became the target range, after the recession of the early ’90s, they’ve shown zero sign of moving for 30 years. Not even during the present inflation surge.

So when nervous-nelly governors decide to err on the safe side, they’re deciding to beat young home buyers even further into the ground. Either sell your house or starve your kids.

Finally, in her answers to questions last week, Bullock implied that the risk of rising inflation expectations was now so great that the Reserve could no longer afford the nicety of distinguishing between supply-side shocks and price rises driven by excessive demand.

Whatever the cause, continuing delay in getting inflation back to target presented such a threat to expectations that rates would have to keep rising regardless.

This means that if our return to target is delayed by supply-side problems – mismatches in the transition to renewable energy, leaps in meat and veg prices caused by extreme weather, or higher oil prices caused by worsening conflict in the Middle East – the home buyers cop it.

In this era of continuing supply shocks, failure to distinguish between the causes of price rises would be a recipe for deep recession. The Reserve’s professed “dual mandate” – full employment – would be out the window.

Jury still out on how much hip pocket pain still coming our way

It’s not yet clear whether the Reserve Bank’s efforts to limit inflation will end up pushing the economy into recession. But it is clear that workers and their households will continue having to pay the price for problems they didn’t cause.

Prime Minister Anthony Albanese didn’t cause them either. But he and his government are likely to cop much voter anger should the squeeze on households’ incomes reach the point where many workers lose their jobs.

And he’ll have contributed to his fate should he continue with his apparent intention to leave the stage-three income tax cuts in their present, grossly unfair form.

The good news is that we’re due to get huge hip pocket relief via the tax cuts due next July. The bad news is that the savings will be small for most workers, but huge – $170 a week – for high-income earners who’ve suffered little from the squeeze on living costs.

Should Albanese fail to rejig the tax cuts to make them fairer, you can bet Peter Dutton will be the first to point this out. But he’ll need to be quick to beat the Greens to saying it.

Those possibilities are for next year, however. What we learnt this week is how the economy fared over the three months to the end of June. The Australian Bureau of Statistics’ “national accounts” show it continuing just to limp along.

Real gross domestic product – the value of the nation’s production of goods and services – grew by only 0.4 per cent – the same as it grew in the previous, March quarter. Looking back, this means annual growth slowed from 2.4 per cent to 2.1 per cent.

If you know that annual growth usually averages about 2.5 per cent, that doesn’t sound too bad. But if you take a more up-to-date view, the economy’s been growing at an annualised (made annual) rate of about 1.6 per cent for the past six months. That’s just limping along.

And it’s not as good as it looks. More than all the 0.4 per cent growth in GDP during the June quarter was explained by the 0.7 per cent growth in the population as immigration recovers.

So when you allow for population growth, you find that GDP per person actually fell by 0.3 per cent. The same was true in the previous quarter – hence all the people saying we’re suffering a “per capita recession”.

As my colleague Shane Wright so aptly puts it, the economic pie is still growing but, with more people to share it, the slices are thinner.

It’s possible that continuing population growth will stop GDP from actually contracting, helping conceal from the headline writers how tough so many households are faring.

But the media’s notion that we’re not in recession unless GDP falls for two quarters in a row has always been silly. What makes recessions such terrible things is not what happens to GDP, but what happens to workers’ jobs.

It’s when unemployment starts shooting up – because workers are being laid off and because young people finishing their education can’t find their first proper job – that you know you’re in recession.

In the month of July, the rate of unemployment ticked up from 3.5 per cent to 3.7 per cent, leaving an extra 35,000 people out of a job. If we see a lot more of that, there will be no doubt we’re in recession.

But why has the economy’s growth become so weak? Because households account for about half the total spending in the economy, and they’ve slashed how much they spend.

Although consumer spending grew by 0.8 per cent in the September quarter of last year, in each of the following two quarters it grew by just 0.3 per cent, and in the June quarter it slowed to a mere 0.1 per cent.

Households’ disposable (after-tax) income rose by 1.1 per during the latest quarter but, after allowing for inflation, it actually fell by 0.2 per cent – by no means the first quarter it’s done so.

What’s more, it fell even though more people were working more hours than ever before. People worked 6.8 per cent more hours than a year earlier.

So why did real disposable income fall? Because consumer prices rose faster than wage rates did. Over the year to June, prices rose by 6 per cent, whereas wage rates rose by 3.6 per cent.

Understandably, people make a big fuss over the way households with big mortgages have been squeezed by the huge rise in interest rates. But they say a lot less about the way those same households plus the far greater number of working households without mortgages have been squeezed a second way: by their wage rates failing to rise in line with prices.​

This is why I say the nation’s households are paying the price for fixing an inflation problem they didn’t cause. It’s the nation’s businesses that put up their prices by a lot more than they’ve been prepared to raise their wage rates.

Businesses have acted to protect their profits and – in more than a few cases – actually increase their rate of profitability. In the process, they risk maiming the golden geese (aka customers) that lay the golden eggs they so greatly covet.

If you think that’s unfair, you’re right – it is. But that’s the way governments and central banks have long gone about controlling inflation once it’s got away. It was easier for them to justify in the olden days – late last century – when it was often the unions that caused the problem by extracting excessive wage rises.

But those days are long gone. These days, evidence is accumulating that the underlying problem is the increased pricing power so many of our big businesses have acquired as they’ve been allowed to take over their competitors and prevent new businesses from entering their industry.

The name Qantas springs to mind for some reason, but I’m sure I could think of others.

Hate rising prices? Please blame supply and demand, not me

Have you noticed how, to many economists, everything gets back to the interaction of supply and demand? Understand this simple truth and you know all you need to know. Except that you don’t. It leaves much to be explained.

Why has the cost of living suddenly got much worse? Because the demand for goods and services has been growing faster than the economy’s ability to supply those goods and services, causing businesses to put their prices up.

Since there is little governments can do to increase supply in the short term, the answer is to use higher interest rates to discourage spending. Weaker demand will make businesses much less keen to keep raising their prices. If you hit demand really hard, you may even oblige businesses to lower their prices a little.

But, as someone observed to me recently, saying that everything in the economy is explained by supply and demand is a bit like saying every plane crash is explained by gravity. It’s perfectly true, but it doesn’t actually tell you much.

Consider this. After rising only modestly for about a decade, rents are now shooting up. Why? Well, some people will tell you it’s because almost half of all rental accommodation has been bought by mum and dad investors using borrowed money (“negative gearing” and all that).

The sharp rise in interest rates over the past year or so has left many property investors badly out of pocket, so they’ve whacked up the rent they’re charging.

Ah no, say many economists (including a departing central bank governor), that’s not the reason. With vacancy rates unusually low, it means that the demand for places to rent is very close to the supply available, and landlords are taking advantage of this to put up their prices.

So, what’s it to be? I think it’s some combination of the two. Had the vacancy rate been high, mortgaged landlords would have felt the pain of higher interest rates but been much less game to whack up the rent for fear of losing their tenants.

But, by the same token, it’s likely that the coincidence of a tight housing market with a rise in interest rates has made the rise in rents faster and bigger than it would have been. It would be interesting to know whether landlords with no debt have increased their prices as fast and as far as indebted landlords have.

The point is that knowing how the demand and supply mechanism works doesn’t tell you much. It doesn’t allow you to predict what will happen to either supply or demand, nor tell you why they’ve moved as they have.

It’s mainly useful for what economists call “ex-post rationalisation” – aka the wisdom of hindsight.

Economic theory assumes that all businesses – including landlords – are “profit-maximising”. But in their landmark book, Radical Uncertainty, leading British economists John Kay and Mervyn King make the heretical point that, in practice rather than in textbooks, firms don’t maximise their profits.

Why not? Well, not because they wouldn’t like to, but because they don’t know how to. There is a “price point” that would maximise their profits, but they don’t know what it is.

To economists, when you’re just selling widgets, it’s a matter of finding the right combination of “p” (the price charged) and “q” (the quantity demanded). Raising p should increase your profit – but only if what you gain from the higher p is greater than what you lose from the reduction in q as some customers refuse to pay the higher price.

What you need to know to get the best combination of p and q is “the price elasticity of demand” – the customers’ sensitivity to changes in price. In textbooks or mathematical models, the elasticity is either assumed or estimated via some empirical study conducted in America 30 years ago.

In real life, you just don’t know, so you feel your way gently, always standing ready to start discounting the price if you realise you’ve gone too far. And the judgments you make end up being influenced by the way you feel, the way your fellow traders feel, what you think the customers are feeling and how they’d react to a price rise.

How flesh-and-blood people behave in real markets is affected by mood, emotion, sentiment, norms of socially acceptable behaviour and other herding behaviour – all the factors that economists knowingly exclude from their models and know little about.

Keynes called all this “animal spirits”. Youngsters would call it “the vibe of the thing”. It’s psychology, not economics. And it’s because conventional economics attempts to predict what will happen in the economy without taking account of airy-fairy psychology that economists’ forecasts are so often wrong.

They may know more about how the economy works than the rest of us, but there’s still a lot they don’t know. Worse, many of them don’t think they need to know it.

It’s clear to me that psychology has played a big part in the great post-pandemic price surge. It didn’t cause it, but it certainly caused it to be bigger than it might have been.

The pandemic’s temporary disruptions to supply and the Ukraine war’s disruption to fossil fuels and food supply provided a cast-iron justification for big price rises, and it was a simple matter for businesses to add a bit extra for the shareholders.

It was clear to the media that big price rises were on the way, so they went overboard holding a microphone in front of every industry lobbyist willing to make blood-curdling predictions about price rises on the way. (I’m still waiting to see the ABC’s prediction of the price of coffee rising to $8 a cup.)

Thus did recognition that the time for margin-fattening had arrived spread from the big oligopolists to every corner store. One factor that constrains the prices of small retailers is push-back from customers – both verbal and by foot.

All the media’s fuss about imminent price rises softened up customers and told the nation’s shopkeepers there would be little push-back to worry about.

In the home rental market, dominated as it is by amateur small investors, who rightly worry about losing a tenant and having their property unoccupied for more than a week or two, it’s the commission-motivated estate agents who know when’s the right time to urge landlords to raise the rent, and how big an increase they can be confident of getting away with.

Why you should and shouldn't believe what you're told about inflation

If you don’t believe prices have risen as little as the official figures say, I have good news and bad. The good news is that most Australians agree with you. The bad news is that, with two important qualifications, you’re wrong.

Last week the officials – the Australian Bureau of Statistics – reminded us of a truth that economists and the media usually gloss over: the rate of inflation, as measured by the consumer price index, can be an unreliable guide to the cost of living. Especially now.

But first, many people who go to the supermarket every week are convinced they know from personal experience that prices are rising faster than the CPI claims. Wrong. Your recollection of the price rises you’ve noticed at the supermarket recently is an utterly unreliable guide to what’s been happening to consumer prices generally.

For a start, only some fraction of the things households buy are sold in supermarkets. The CPI is a basket of the manifold goods and services we buy – some weekly, some rarely.

Apart from groceries, the basket includes the prices of clothing and footwear, furnishings, household equipment and services, healthcare, housing, electricity and gas, cars, petrol and public transport, internet fees and subscriptions, recreational equipment and admission fees, local and overseas holidays, school fees, insurance premiums and much more.

But the main reason no one’s capable of forming an accurate impression of how much prices have risen is our selective memories. Have you noticed that no one ever thinks prices have risen by less than the CPI says?

That’s because we remember the big price rises we’ve seen – they’re “salient”, as psychologists say; they stick out – but quickly forget the prices that have fallen a bit. Nor do we take much notice of prices that don’t change. We don’t, but the statisticians do – as they should to get an accurate measure of the rise in the total cost of all the stuff in the basket.

Sometimes the price of the latest model of a car or appliance has risen partly because it now does more tricks. Because they’re trying to measure “pure” price increases, the statisticians will exclude the cost of this “quality increase”.

My son, who watches his pennies, was sure the eggheads in Canberra wouldn’t have noticed “shrinkflation” – reducing the contents of packets without changing the price. No. This trick’s intended to fool the unwary punter; it doesn’t fool the statisticians. It counts as a price rise.

But now for the two reasons the CPI can indeed be misleading. The first is that averages can conceal as much as they reveal. Remember the joke about the statistician who, with his head in the oven and his feet in the fridge, said he was feeling quite comfortable on average.

The most recent news that, according to the CPI, prices rose by 0.8 per cent in the three months to the end of June, and 6 per cent over the year to June, was an average of all the households – young, middle-aged and old; smokers and non-smokers, drinkers and teetotallers, no kids and lots, renters, home buyers and outright owners – living in the eight capital cities.

Now note this. Economists, politicians and the media tend to treat the CPI and the “cost of living” as synonymous. But if you read the fine print, the bureau says that, while the CPI is a reasonably accurate measure of the prices of the goods and services in its metaphorical basket, it’s not, repeat not, a measure of anyone’s cost of living.

Why not? Partly because it does too much averaging of households in very different circumstances, but mainly because of the strange – and, frankly, misleading – way it measures the housing costs of people with mortgages.

The cost of being a home buyer is the interest component of your monthly payments on your mortgage.

But that’s not the way the CPI measures the cost of home buying. Rather, it’s measured as the price of a newly built house or unit. Which makes little sense. Many people with mortgages haven’t bought a new home.

And even those people who did buy a newly built home, did so some years ago when house prices were lower than they are now.

The bureau changed to this strange arrangement a couple of decades ago. Why? Because the Reserve Bank pressured it to. Why? Well, as you well know, the Reserve uses its manipulation of interest rates to try to keep the annual rate at which prices are rising, as measured by the CPI, between 2 and 3 per cent on average.

But, after it had adopted that target in the mid-1990s, it decided that it didn’t want the “instrument” it was using to influence prices – interest rates – to be included in the measure of prices it was targeting, the CPI.

So, the bureau – unlike other national statistical agencies – switched to measuring home buyers’ housing costs in that strange way. And the bureau began publishing, in addition to the CPI, various “living cost indexes” for “selected household types”.

The main difference between these indexes and the CPI is that home buyers’ housing cost is measured as the interest they’re paying on their loans, not the cost of a newly built house. But, of course, different types of households will have differing collections of goods and services in the basket of things they typically buy.

So, whereas the CPI tells us that prices rose by 6 per cent over the year to the end of June, the living cost indexes show rises varying between 6.3 per cent and 9.6 per cent.

Among the four selected household types (which between them cover about 90 per cent of all households), the type with the highest price rises was the employees, whose costs rose by 9.6 per cent overall.

That’s mainly because most of the people with mortgages would be is this category. Mortgage interest charges rose by 9.8 per cent in the quarter and (hang onto your hat) by 91.6 per cent over the year.

At the other end of the spectrum, supposedly “self-funded retirees” had the lowest living-cost increase of 6.3 per cent – mainly because almost all of them would own their homes outright.

Then come age pensioners, with cost rises of 6.7 per cent – few with mortgages, but some poor sods renting privately.

And finally, “other government transfer recipients” - those of working age, including people on unemployment benefits, on the disability pension and some students. They’re costs are up 7.3 per cent. Some of these would have mortgages, most would have seen big rent rises.

What this proves is that using interest rates to control prices makes the cost of living worse before making it better.

Don't miss the good news among the bad: we've hit jobs, jobs, jobs

Here is the news: not everything in the economy is going to hell. Right now, jobs, jobs, jobs are going great, great, great.

The news media (and yours truly) focus on whatever’s going wrong – the cost of living, interest rates, to take two minor examples – because they know that’s what interests their paying customers most.

This bias in our thinking exists because humans have evolved to be continually on the lookout for threats. Those threats used to be wild animals, poisonous berries and the rival tribe over the river, but these days they come more in the form of politicians who aren’t doing their job and business people on the make.

If you’re not careful, however, the preoccupation with bad news can leave you with a jaundiced view of the total picture. Everything’s bad and nothing’s good.

But it’s rare for anything to be all bad or all good. And, particularly where the economy’s concerned, it’s common for good things and bad things to go together.

For instance, when unemployment is high, inflation is usually low. And when inflation is high, unemployment’s usually low. (It’s in the rare event where they’re both high at the same time – “stagflation” – that you know we’re really in trouble.)

So, when our present Public Enemy No. 1 – Reserve Bank governor Dr Philip Lowe – began a speech last week by making this point, I realised I should make sure that you, gentle reader, hadn’t missed the rose among all the thorns.

Lowe said the high inflation we’re experiencing was “one of the legacies of the pandemic and of Russia’s invasion of Ukraine”. But “another remarkable, but less remarked upon, legacy of the pandemic is the significant improvement in Australia’s labour market”.

“Significant improvement” is putting it mildly. Have you heard of “full employment”, where everyone who wants a job has one? It’s the way our economy used to be for about three decades following World War II.

But you have to be as ancient as me to remember what it was like. One reason I quit my job and embarked on a course that eventually led me to this august organ was the knowledge that, should I need to get a job, all I had to do was wait until next Saturday’s classified job ads, and pick the one I wanted.

That’s full employment. And the world hasn’t been like that since Gough Whitlam was prime minister. Until now. We have more people with jobs than ever in our history.

At about 3.5 per cent, the rate of unemployment is lower than at any time since 1974. And before any of the imagined experts let fly on Twitter, this is not because any government, Labor or Liberal, has fiddled the figures.

What’s true is that, in recent decades, more people have been under-employed – they haven’t been able to get as many hours of work as they’ve needed.

But as Lowe says, in recent times, people have found it easier to obtain more hours of work. So the rate of underemployment is at multi-decade lows, and the proportion of jobs that are full-time is higher than it’s been in ages.

We now have 64 per cent of people of working-age actually in a job, the highest ever. The proportion of people either already in a job or actively seeking one – the “participation rate” - is also at its highest.

A lot of this is explained by the record high in women’s participation in the labour force.

Lowe says the rate of participation by young people is “the highest it has been in a long time” and the youth unemployment rate is “the lowest that it has been in many decades”.

If all that’s not worth celebrating, I don’t know what is.

But for all those desperate to find a negative – often for reasons of partisanship – it’s not that you can’t believe the figures. It’s this: can you believe they’ll continue?

With the Reserve raising interest rates so fast and far to slow the economy’s growth and reduce inflation pressure, it’s clear that this is as good as it gets in the present episode.

For the past couple of months, we’ve seen the figures edging back a fraction from their best, and on Thursday we’ll see if that’s yet become a trend.

At present, Lowe is at the controls bringing the economic plane in to land. He’s aiming for a soft landing, but may miscalculate and give us a bumpy landing which, to mangle the metaphor, will send unemployment shooting up.

If so, we may have had just a fleeting glimpse of full-employment nirvana before it disappeared into the mist.

But for the more optimistically inclined, even if the landing is harder than planned, we’ll have started from a much lower unemployment rate than in past recessions, meaning it won’t go as high as it has before, and it should be easier to get back to the low levels we’d now like to become accustomed to.

How about sharing the economic pain arround?

If you don’t like what’s happening to interest rates, remember that although the managers of the economy have to do something to reduce inflation, it’s not a case of what former British prime minister Maggie Thatcher called TINA – there is no alternative.

As Reserve Bank governor Dr Philip Lowe acknowledged during his appearance before the House of Representatives Standing Committee on Economics last week, there are other ways of stabilising the strength of demand (spending) and avoiding either high inflation or high unemployment, which are worth considering for next time.

So, relying primarily on “monetary policy” – manipulating interest rates – is just a policy choice we and the other advanced economies made in the late 1970s and early 1980s, after the arrival of “stagflation” – high unemployment and high inflation at the same time – caused economists to lose faith in the old way of smoothing demand, which was to rely primarily on “fiscal policy” – manipulation of taxation and government spending in the budget.

The economic managers have a choice between those two “instruments” or tools with which smooth demand. The different policy tools have differing sets of strengths and weaknesses.

Whereas back then we were very aware of the weaknesses of fiscal policy, today we’re aware of the weaknesses of monetary policy, particularly the way it puts a lot more pain on people with home loans than on the rest of us. How’s that fair?

Lowe says the conventional wisdom is to use monetary policy for “cyclical” (short-term) problems and fiscal policy for “structural” (lasting) problems, such as limiting government debt.

But it’s time to review what economists call “the assignment of instruments” – which tool is better for which job. The more so because the government has commissioned a review of the Reserve Bank’s performance for the first time since we moved to monetary policy dominance.

It’s worth remembering that the change of regime was made at a time when Thatcher and other rich-country leaders were under the influence of the US economist Milton Friedman and his “monetarism”, which held that inflation was “always and everywhere a monetary phenomenon” and could be controlled by limiting the growth in the supply of money.

It took some years of failure before governments and central banks realised both ideas were wrong. They switched back to the older and less exciting notion that increasing interest rates, by reducing demand, would eventually reduce inflation. There was no magic, painless way to do it.

Macroeconomists long ago recognised that using policy tools to manage demand was subject to three significant delays (“lags”). First there’s the “recognition lag” – the time it takes the econocrats and their bosses to realise there’s a problem and decide to act.

Then there’s the “implementation lag” – the delay while the policy change is put into effect. Lowe described the cumbersome process of cabinet deciding what changes to make to what taxes or spending programs. Then getting them passed by both houses, then waiting a few weeks or months for the bureaucrats to get organised before start day.

He compared this unfavourably with monetary policy’s super-short implementation delay: the Reserve Bank board meets every month and decides what change to make to the official interest rate, which takes immediate effect.

He’s right. While the two policy tools would have the same recognition lag, monetary policy wins hands down on implementation lag.

But on the third delay, the “response lag” – the time it takes for the measure, once begun, to work its way through the economy and have the desired effect on demand – monetary policy is subject to “long and variable lags”.

Lowe said it took interest rate changes 18 months to two years to have their full effect. But I say most budgetary changes – particularly tax changes – wouldn’t take nearly that long. So, that’s a win for fiscal.

The sad truth is that measures to strengthen demand by cutting interest rates, or cutting taxes and increasing government spending, are always popular with voters, whereas measures to weaken demand by raising interest rates, or raising taxes and cutting government spending, are always unpopular.

This meant politicians were always reluctant to increase interest rates when they needed to, Lowe said. This is a good argument for giving the job to the econocrats at the central bank and making them independent of the elected government.

This became standard practice in the rich economies, although we didn’t formalise it until the arrival of the Howard government in 1996. Lowe advanced this as a good reason to stick with monetary policy as the dominant tool for short-term stabilisation of demand.

Against that, using monetary policy to get to the rest of us indirectly via enormous pressure on the third of households with mortgages shares the burden in a way that’s arbitrary and unfair.

What’s more, it’s not very effective. Because such a small proportion of the population is directly affected, the increase in interest rates has to be that much bigger to achieve the desired restraint in overall consumer spending.

But if the economic managers used a temporary percentage increase in income tax, or the GST, to discourage spending, this would directly affect almost all households. It would be fairer and more effective because the increase could be much smaller.

Various more thoughtful economists – including Dr Nicholas Gruen and Professor Ross Garnaut – have proposed such a tool, which could be established by legislation and thus be quickly activated whenever needed.

A special body could be set up to make these decisions independent of the elected government. Ideally, it would also have control over interest rates, so one institution was making sure the two instruments were working together, not at cross purposes.

Another possibility is Keynes’ idea of using a temporary rate of compulsory saving – collected by the tax office – to reduce spending when required, without imposing any lasting cost on households.

They say if it ain’t broke, don’t fix it. It’s obvious now that macroeconomic management needs a lot of fixing.
