RBA Hikes Cash Rate to 4.85%: Highest in 18 Years Amid Inflation
In an extraordinary Melbourne Cup Day monetary policy announcement, the Reserve Bank of Australia (RBA) Board resolved on Tuesday, 3 November 2026, to lift the official cash rate target by 25 basis points to 4.85%. The decision marks the fifth rate hike delivered in 2026, propelling Australia's benchmark borrowing costs to their highest level in 18 years—matching the peak recorded in October 2008 before the global financial crisis. The Board also lifted the interest rate on Exchange Settlement balances to 4.75%.
The monetary tightening follows an unwelcome resurgence in domestic prices. Data from the Australian Bureau of Statistics (ABS) revealed that headline Consumer Price Index (CPI) inflation accelerated to 4.3% year-on-year in the September quarter of 2026, up from 3.8% in June. Crucially, the trimmed mean—the RBA's preferred core inflation gauge—rose to 4.1%, remaining outside the statutory 2% to 3% target band for a seventeenth consecutive quarter.
Persistent domestic demand, sticky services inflation, and global energy shocks forced the RBA's hand. Yet the decision fractured the nine-member board in a historic 6-3 division, sparking political friction in Canberra and confronting millions of mortgaged households with immediate repayment increases.
