Tuesday's hike took the cash rate to 4.6 per cent, the highest in 15 years. The Reserve Bank is now considered newly hawkish and has signalled more rate hikes could come. The current rate is the second highest in the advanced world outside Iceland, and significantly higher than nations such as New Zealand and Canada, where policymakers accepted more job losses to curb inflation.
The impact on households is expected to be more severe than the 2023 cycle. During that earlier period, COVID stimulus was still supporting household budgets. That support has now gone. While savings buffers remain in reasonable shape, the share of mortgages on fixed rates has fallen from about 40 per cent then to around 5 per cent now, leaving many more borrowers exposed to variable rates.
The political ramifications are significant. Prime Minister Anthony Albanese, who previously used election spending to see off former Coalition leader Peter Dutton, now faces a new threat from One Nation's Pauline Hanson. With a depleted budget, his options for similar relief are limited.
