To understand this thinking lets go back to the whole objective of the RBA.
The RBA has two jobs – maintain a stable currency (which means keep inflation steady) and maintain full employment.
The problem is the RBA thinks you can only have full employment when inflation is below 3%.This is because it has swallowed whole the economic theory of the “non-accelerating inflation rate of unemployment” (NAIRU) where “full employment” is at a point where inflation is not accelerating (ie going from 3% to 4% to 5% etc).
It’s all based around a belief that if unemployment falls too low, too many people are earning money (so spending) and also businesses will have to increase wages to keep staff, which means more money being spent and that will also raise prices and thus cause inflation to rise (or accelerate).
Higher interest rates slow spending (because you have to pay your home loan) and also makes it harder for small business to borrow.
It’s bunkum, but anyway, to achieve this, back in the 1990s the RBA followed other central banks (New Zealand was the first) by setting an inflation target. They chose 2% to 3% .
The policy notionally delivers stable inflation, but inherently prioritises low wage growth and low inflation ahead of low unemployment.
There is no reason why the target should be 2% to 3%. Canada for example targets 1% to 3% inflation.
The 2% to 3% target was basically adopted just because in 1992 the RBA governor at the time Bernie Fraser gave a speech in which he said “there is no reason why the current underlying inflation rate of 2 to 3 per cent cannot be sustained” and then in 1994 he gave another speechin which he suggested “In our judgment, underlying inflation of around 2 to 3 per cent is a reasonable goal for monetary policy.”
And that was it.
They could make it 2% to 4% or 3% to 4%, or they could, which Michele Bullock seems to think is the right thing to do, and not really have a target range but a midpoint of 2.5%.
The point is this is all arbitrary.
But it matters, because rather quietly earlier this year the RBA admitted it no longer believed in the NAIRU.
Sarah Hunter, the Assistant Governor (Economic) of the RBA gave a speech in which she noted that inflation no longer “accelerates” when unemployment is lower than the RBA thinks it should be – it’s just that inflation is above 3%. Hunter said “the ‘non-accelerating’ part of the NAIRU name is a bit out of date”
Why does this matter?
As Hunter said:
“When the labour market is tight and operating beyond full employment, we expect to see inflationary pressures across the economy and an elevated rate of inflation. But the rate of inflation doesn’t have to be continually increasing.”
What that means is the RBA no longer believes it needs inflation to be rising in order for it to think unemployment is too low and to justify raising rates – it just needs inflation above 3%.
So the RBA believes it needs to keep raising rates in order to get more people to be out of a job purely because it has set 2% to 3% as the inflation target.
And so they will keep doing so. And when inflation is below 3% they will say we have “full employment”

Probably a dumb question; but why can’t you ask her? Or why can’t someone ask something similar? Is there tight control on who can be at these events? Are there no journalists present with a good understanding of economics?
'yell obscenities at the RBA' - well Mr Grogs start a yellin' then
