RBA Hikes Interest Rate to 4.60% as Inflation Risks Rise

The Reserve Bank of Australia raised interest rates by 25 basis points on Tuesday, taking borrowing costs to their highest level in nearly 15 years as policymakers respond to persistent inflation and rising energy prices.

The RBA increased its cash rate target to 4.60%, the highest since October 2011. The decision was unanimous, with members of the rate-setting board pointing to increasingly persistent inflation pressures across the Australian economy.

The move marked the central bank’s fourth rate hike of 2026 after it began a new monetary tightening cycle earlier this year. Markets had widely anticipated the increase following hawkish comments from RBA officials and recent inflation readings that remained above the bank’s 2% to 3% annual target range.

In its policy statement, the RBA said it would continue taking necessary steps to return inflation sustainably to target, including raising the cash rate further if required.

Policymakers said some upside inflation risks identified in August were now materializing. Higher global energy prices stemming from the prolonged Middle East conflict have added to price pressures, while growing technology demand linked to artificial intelligence has also contributed to inflation.

Domestic capacity constraints remain another concern. The RBA has previously indicated that demand may need to weaken to ease inflation, potentially resulting in slower economic growth and softer employment conditions.

Capital Economics analysts said they still believe the cash rate has reached its peak but acknowledged that risks to that outlook are increasing. They highlighted the RBA’s decision to remove its previous description of monetary policy as “somewhat restrictive,” potentially signaling greater uncertainty over whether current rates are sufficient to contain inflation.

Australian markets showed a relatively muted reaction to the decision. The Australian dollar strengthened slightly following the announcement, with AUD/USD gaining about 0.06%, while the benchmark ASX 200 slipped around 0.1%.

Investors will now closely watch upcoming Australian inflation, employment and economic growth data for indications of whether the RBA could deliver another interest rate hike.
