The Australia Institute’s chief economist is betting on a Melbourne Cup interest rate rise, after RBA governor Michele Bullock confirmed Australia’s rate hikes this year have outpaced those of other major advanced economies.
The Reserve Bank has lifted rates four times this year, taking the official cash rate to 4.6 per cent – its highest level in 15 years.
During Senate estimates this week, Senator Dave Sharma pressed Ms Bullock on whether any of the world’s 43 advanced economies had raised rates by 100 basis points or more this year.
“The ones we compare ourselves with, no, Senator,” she replied.
Ms Bullock said Australia was in a different position to other countries, with demand outstripping supply even before the latest global instability – meaning there weren’t enough goods, services or workers to meet demand, pushing prices higher.
“The problem for us is that we started from a position of excess demand. Other countries did not,” she said.
The comments came as fresh figures showed Australia’s annual inflation rate had climbed to 4.3 per cent, up from 4 per cent in August, well above the RBA’s target range of two to three per cent.
The numbers have fuelled concerns that another interest rate rise when the RBA meets on Tuesday.
However, Ms Bullock cautioned that the impact of previous increases was still filtering through the economy.
“Because monetary policy works with a lag, the full effects of recent rate increases are yet to be felt on domestic activity,” she said.
Greg Jericho, chief economist at the Australia Institute, agreed, warning unemployment was already rising, and another rate hike will make it worse.
“The full impact of the rate rises is yet to flow through, but we are already seeing unemployment rise from 4.1 per cent at the start of the year to 4.7 per cent,” he said.
“Given the most recent rate rise occurred at the end of September and the RBA is almost certain to raise rates next week, that means it is very likely that unemployment will rise closer to 5 per cent by the end of this year.”

Greens senator Nick McKim pointed to Australia’s data centre investment pipeline, which he valued at around $156 billion and described as the world’s third largest, and questioned the inflationary impact of the “massive looming investment”.
Ms Bullock acknowledged that the data centre boom was adding to inflationary pressures, with construction projects competing for skilled labour.
“Investment’s been much stronger than we thought,” she told the committee.
“To the extent that it’s drawing resources from there, those resources have to come from somewhere. So that does add to inflationary pressure.”
RBA Assistant Governor Sarah Hunter also emphasised the scale of investment.
“Business investment, which has increased very sharply over the last 12 months, and a decent portion of that increase has been from the data centre investment,” she said.
Senator Fatima Payman questioned whether the RBA should be advising the government on other measures to tackle inflation, rather than relying solely on interest rates.
“It’s not within our remit, Senator,” replied Ms Bullock.
“Our remit is to use the tools available to us to deal with inflation and full employment. That is what we do. Independence goes both ways.”
Ms Bullock maintained that it was not the RBA’s role to advise government on policy decisions.
“They’re not for us to tell the government what to do,” she said.
Earlier this month, former RBA governor Bernie Fraser argued the central bank was “over preoccupied” with inflation and encouraged Treasurer Jim Chalmers to be more outspoken in his criticism of its approach.
