Australia’s central bank on Tuesday raised interest rates by the most in 22 years and flagged more tightening to come as it battles to restrain surging inflation, stunning markets and sending bond yields flying.

Wrapping up its June policy meeting, the Reserve Bank of Australia (RBA) lifted its cash rate by 50 basis points to 0.85 per cent, wrong-footing investors who had wagered on a move of either 25 or 40 basis points.

“Given the current inflation pressures in the economy, and the still very low level of interest rates, the Board decided to move by 50 basis points today,” RBA governor Philip Lowe said in a statement.

“The Board expects to take further steps in the process of normalizing monetary conditions over the months ahead.”

The central bank had already lifted rates by a quarter-point in May, the first increase since 2010, and many had thought it would stick to quarter-point moves. The last time it hiked by more was in early 2000.

Investors initially sent the local dollar up half a US cent to as far as US$0.7248, where it ran into profit-taking. Bonds took a beating as three-year yields shot up 16 basis points to 3.27 per cent, levels not seen since early 2012.

Futures shifted to price in the real risk of another 50-basis-point rise in July and rates around 1.5 per cent by August after the release of inflation figures for the second quarter, which are expected to be red-hot.

“The door is open to further 50bp hikes with inflation pretty much the sole focus, similar to the front-loading of hikes we have seen by other central banks,” said Alvin Tan, an analyst at RBC Capital Markets.

“The RBA looks to be firmly in that mode now as it heads towards neutral sooner rather than later.”

Mr. Lowe in the past has said “neutral” for rates could be around 2.5 per cent.


Consumer price inflation had already hit a 20-year peak of 5.1 per cent in the first quarter and could approach 6 per cent this quarter amid rising costs for energy, food, rents and home building.

“Higher prices for electricity and gas and recent increases in petrol prices mean that, in the near term, inflation is likely to be higher than was expected a month ago,” Mr. Lowe said.

In just his third week in office, Treasurer Jim Chalmers warned Australians inflation would get worse before it got better and to brace for a “difficult and expensive” winter.

Mr. Chalmers promised some cost-of-living relief would be included in a budget due in October, centred on child care and health. The Labor government ousted the Liberal-National coalition in an election in late May, inheriting almost one trillion Australian dollars ($906-billion) in debt and endless budget deficits.

With inflation looking set to stay high for longer, investors are wagering the RBA will have to raise rates to near 3 per cent by the end of the year making it easily one of the most aggressive tightening campaigns on record.

Most economists had doubted rates would rise that far given house-hunting Australians are sitting on 2 trillion Australian dollars in mortgage debt, making them very sensitive to borrowing costs.

House prices have already begun to slip in Sydney and Melbourne after a stellar run in 2021, and consumer sentiment is back to the depths of the pandemic.
