It’s not hard to determine what part of GDP has done the most to cause that slowdown. One component accounts for more than half of total GDP – household consumption spending. Here’s how it’s grown over the past six quarters: 0.8 per cent, 0.2 per cent, 0.5 per cent, 0.0 per cent, 0.3 per cent and 0.4 per cent.

A further sign of how tough households are doing: the part of their disposable income they’ve been able to save each quarter has fallen from 10.8 per cent to 0.9 per cent over the past two years.

So, if the object of the squeeze has been to leave households with a lot less disposable income to spend on other things, it’s been a great success.

The point is, when our demand for goods and services grows faster than the economy’s ability to supply them, businesses take the opportunity to increase their prices – something we hate.

But if we want the authorities to stop prices rising so quickly, they have only one crude way to do so: by raising mortgage interest rates and income tax to limit our ability to keep spending so strongly.

When the demand for their products is much weaker, businesses won’t be game to raise their prices much.

So, is it working? Yes, it is. Over the year to December 2022, consumer prices rose by 7.8 per cent. Since then, however, the rate of inflation has fallen to 3.6 per cent over the year to March.

Now, you may think that 3.6 per cent isn’t all that far above the Reserve’s inflation target of 2 per cent to 3 per cent, so we surely must be close to the point where, with households flat on the floor with their arms twisted up their back, the Reserve is preparing to ease the pain.

But apparently not. It seems to be worried inflation’s got stuck at 3.6 per cent and may not fall much further. In her appearance before a Senate committee this week, Reserve governor Michele Bullock said nothing to encourage the idea that a cut in interest rates was imminent. She even said she’d be willing to raise rates if needed to keep inflation slowing.

It’s suggested the Reserve is worried that we have what economists call a “positive output gap”. That is, the economy’s still supplying more goods and services than it’s capable of continuing to supply, creating a risk that inflation will stay above the target range or even start going back up.

With demand so weak, and so many people writhing in pain, I find this hard to believe. I think it’s just a fancy way of saying the Reserve is worried that employment is still growing and unemployment has risen only a little. Maybe it needs to see more blood on the street before it will believe we’re getting inflation back under control.

If so, we’re running a bigger risk of recession than the Reserve cares to admit. And if interest rates stay high for much longer, I doubt next month’s tax cuts will be sufficient to save us.

Another possibility is that what’s stopping inflation’s return to the target is not continuing strong demand, but problems on the supply side of the economy – problems we’ve neglected to identify, and problems that high interest rates can do nothing to correct.

Problems such as higher world petrol prices and higher insurance premiums caused by increased extreme weather events.

I’d like to see Bullock put up a big sign in the Reserve’s office: “If it’s not coming from demand, interest rates won’t fix it.”
