The Reserve Bank of Australia raised its official cash rate to 4.6% on Tuesday, the fourth increase this year and the highest level since late 2011. The 25 basis point rise will add about A$120 per month to an average mortgage of A$730,000, bringing total annual increases to A$480 monthly. The RBA cited persistent inflation at 3.5% and stronger-than-expected economic growth, though it warned of recession risks if tightening goes too far.

Why the RBA kept hiking despite economic weakness

The RBA’s Monetary Policy Board voted unanimously to raise rates, citing inflation that remains above its 2-3% target. Annual inflation stood at 3.5% in July, with underlying inflation at 3.6%. The board said recent inflation outcomes were stronger than expected, driven by higher global energy prices, Middle East conflict spillover, and AI-related demand for technology goods. The RBA left the door open to further increases, stating it would do what is necessary to bring inflation back to target.

Mortgage holders face mounting pressure

Australians with home loans are bearing the brunt of the hikes. Over 2026, the four rate rises have added A$480 monthly to average family repayments. For a typical new mortgage of A$731,000 at 6.2%, the latest rise adds A$119 to monthly payments of A$4,477. Families already stretched financially are cutting back sharply. One Sydney toolmaker with a A$345,900 loan balance, paying A$625 weekly, told The Guardian his family has eliminated streaming services, reduced food spending, and stopped family holidays. His wife has returned to full-time work to cope with the pressure.

Savers get relief while recession risks loom

While mortgage holders suffer, savers are seeing higher returns on deposit accounts as banks pass on rate rises. However, the RBA faces a difficult balancing act. RBA Governor Michele Bullock told reporters that recession is not the bank’s central case at this point, yet the economy is already losing momentum and the housing market is weak. The key challenge is whether the RBA can control inflation without triggering a sharper slowdown than intended.

Banks pass on the increase to customers

Commonwealth Bank announced it will increase home loan variable rates by 0.25% per annum, effective October 9, 2026. CBA’s Group Executive Retail Banking, Angus Sullivan, said the bank’s teams are ready to help customers understand their options, including switching to fixed-rate loans for payment certainty or splitting loans to combine stability with flexibility. Customers experiencing financial difficulty can contact CBA’s Financial Assistance Solutions Team.

Final Thoughts

The RBA’s fourth rate rise of 2026 has pushed the cash rate to its highest level in 15 years, adding significant monthly costs to Australian households already cutting discretionary spending. The central bank faces mounting pressure to balance inflation control against recession risk.
