Various economists are arguing that price rises have been “broadly based” so as to show that price rises are now “demand-driven”, but the main reason so many prices have risen is that there have been so many different supply shocks coming at the same time, with so many indirect effects, ranging from transport costs to fertiliser and food.

Two thirds of the quarterly increase in prices came from four items. In order of effect on the index: cost of new dwellings (up 5.7 per cent), fuel prices (11 per cent), university fees (6.3 per cent) and food (2.8 per cent).

Of those, only new dwelling prices can be attributed mainly to strong demand, coming from the now-ended HomeBuilder stimulus measure. The rise in uni fees was a decision of the Morrison government.

America’s economy is “overheating”, but ours isn’t. It’s true our jobs market is very tight, and that much of this strength is owed to our now-discontinued stimulus measures.

But, paradoxically, the economics profession’s ideological commitment to growth by immigration has blinded it to the obvious: job vacancies are at record levels also because of another pandemic-related supply constraint: our economy has been closed to all imported labour (and we even sent a fair bit of it back home). This constraint has already been lifted.

The thing about supply shocks is that they’re once-only and not permanent. So, left to its own devices, without further shocks the rate of price increase should fall back over time. Petrol and diesel prices, for instance, have already fallen a bit but, in any case, won’t keep rising by 35 per cent a year year-after-year.

It’s sloppy thinking to think a rise in prices equals inflation. The public can be forgiven such a basic error, but professional economists can’t. A true inflation problem arises only when the rise in prices is generalised and is ongoing. That is, when it’s kept going by a wage-price spiral.

When a huge rise in prices, from whatever source, leads to an equally huge – or huger – rise in wages, which prompts a further round of price rises. That’s inflation.

In their panic, business economists have assumed that the loss of employee bargaining power we’ve observed in most of the years since the global financial crisis, which has done so much to confound the econocrats’ wage and growth forecasts, and caused inflation to fall short of the Reserve’s target range for six years in a row, has suddenly been transformed. Union militance is back!

Really? I’m sure employees and what remains of their unions will be asking for pay rises of at least 5 per cent this year, but how many will get anything like that much? They’ll all be on strike until they do, you reckon?

They’re safe to get more than the 2.3 per cent they got in the year to December, according to the wage price index, but the greatest likelihood is that real wages will continue to fall. And the cure for that is to raise interest rates, is it?

It is true that, if wages rose in line with prices, we would have an inflation problem, but how likely is that?

There’s been much concern about stopping a rise in “inflation expectations”, but this thinking involves a two-stage process: in expectation of higher inflation, businesses raise their prices. And in expectation of higher inflation, unions raise their wage demands.

All the sabre-rattling we’ve seen by the top retailers and their employer-equivalent of union bosses – so breathlessly reported by the media – suggests they’re increasingly confident they can get away with big price rises. But how much success individual employees and unionised workers have in realising their expectations remains to be seen.

Perhaps in this more inflation-conscious environment, employers will be a lot more generous – more caring and sharing – than they have been in the past decade. Perhaps.

The Reserve is under immense pressure from the financial markets, the bank and business economists, the media, the actions of other central banks and even the International Monetary Fund to start raising interest rates.

It will, with little delay. It must be seen to act. But whether it’s at panic stations with the media and the business economists is doubtful. And you don’t have to believe the inflation genie is out of the bottle to see that the need for interest rates to be at near-zero emergency levels has passed.

As BetaShares’ David Bassanese has predicted, the Reserve will be “not actively trying to slow the economy, but rather [will] begin the process of interest-rate normalisation now that the COVID emergency has passed”. Moving to “quantitative tightening” will be part of that process.
