What did the RBA decide on March 17, 2026?

The RBA raised the cash rate by 25 basis points to 4.1% in a close 5-4 vote. The board signaled data dependence as inflation risks from services and oil remain. Banks have begun passing the increase to variable loans, and markets priced higher-for-longer policy near term.

How much will my mortgage repayments increase?

A 0.25 percentage point increase typically adds about A$15 per A$100,000 to monthly repayments on a 30-year principal-and-interest loan. For A$600,000, that is roughly A$90 a month. Check your lender’s comparison rate and consider offsets or refinancing to reduce interest costs.

How did markets respond to the hike?

The ASX 200 closed up 0.4% as investors weighed tighter policy against hopes for a mid-year plateau. Banks often benefit on margin expectations, while rate-sensitive tech and REITs can be mixed. Bond yields at the front end usually rise on hawkish surprises, pressuring long-duration equities.

Will the RBA pause in May?

A pause is possible if monthly CPI, wages, and growth cool further. Economists say inflation may need more time, especially with Brent above $104. The board’s close 5-4 split shows rising uncertainty, so upcoming data will heavily influence whether RBA interest rates hold or rise again.
