For five years, the Reserve Bank of Australia (RBA) has been trying to bring inflation back to its 2.5% target, and for years it has essentially failed. This was reported by Qazaqyia.kz citing The Guardian.

The result is a cost-of-living crisis that has generated intense community grievance. The RBA's deputy governor, Andrew Hauser, acknowledged as much on the ABC's 7:30 report on Tuesday.

"People are furious about inflation," Hauser said. "Inflation has been above target for a long period of time and at some point we will have to say, 'That is long enough'."

Are we at that point? Not yet, said Hauser, even as he hinted we are getting closer every day.

The RBA's nine-member board had hoped this year's three interest rate hikes would be enough to bend the arc of inflation slowly back to reach 2.5% by the end of next year.

The latest blow is the complete breakdown of the US-Iran ceasefire, with escalating tit-for-tat strikes on oil tankers and infrastructure in and around the Strait of Hormuz.

The global oil benchmark has risen above $US100 a barrel for the first time since July. Fuel prices are tracking higher once again, with unleaded approaching $2.10 a litre and diesel passing $2.50.

Then there is this year's sudden explosion in datacentre investment. That has heaped pressure on a construction sector already struggling to get the materials and labour it needs to build the massive pipeline of work to build homes, roads and rails.

Households are complaining a lot and feeling depressed, but there's still a surprising lot of spending happening, which is keeping consumption growth ticking along.

Meanwhile, Australia's productivity performance – the thing that could make it easier for the economy to grow without pushing inflation up – remains flat.

Investors and an increasing number of economists believe we are approaching that point when the RBA has to say "enough is enough" and act more aggressively to get price rises back under control.

Financial markets are pricing in more than a 70% chance of another rate hike on 29 September, and even the chance of a second by the end of the year.

"Of course we could raise interest rates sharply," Hauser said. "We could do it tomorrow. We could no longer take seriously the full employment part of our objective [and say] we're gonna bring inflation down come hell or high water."

Here Hauser is pointing out that the RBA has not been asleep at the wheel, but has been making a conscious calculation.

Since mid-2021, annual inflation has only been below 3% for one year. On the other hand, unemployment has been below 5% for almost all of that time – a labour market record unmatched in modern Australian history.

"The reason as a board we have decided to take it slowly is to preserve as many jobs in this country as we could," Hauser said, and not for the first time.

"We have one big problem, and that's inflation," he said. "Inflation is too high, that's why we raised interest rates three times at the beginning of this year. The question now, frankly, for us is have we done enough, or is more needed?"
