Australia’s central bank raised its benchmark interest rate by 25 basis points to 4.85% on Tuesday, the highest level in 18 years. The Reserve Bank of Australia warned that inflation will remain elevated through much of 2027. It pointed to energy costs and AI-related investment as key sources of price pressure.
The monetary policy board voted 6–3 for the increase, with three members preferring to hold rates at 4.60%. The decision was widely expected. The bank pushed back its forecast for inflation to return to the top of its 2% to 3% target range until late 2027, around three quarters later than previously expected.
The board said AI-related investment is driving rapid growth in prices for technology-related goods. Higher fuel and commodity prices affected by the Middle East conflict are also adding to inflation. The decision underscores how new cost pressures are complicating monetary policy.
Treasurer Jim Chalmers said the decision was widely expected but would not make things easier for families and businesses. He called it difficult news for many Australians already paying a hefty price for circumstances outside their control. The increase will raise borrowing costs for mortgage holders and firms.
The move contrasts with the US Federal Reserve’s decision to hold rates last week. Fed officials have also warned that the AI investment boom is adding to price pressures, including for computer equipment and utilities. The divergence highlights the global challenge of containing inflation amid rapid technology spending.
Higher rates are intended to cool demand and bring inflation back to target. They also risk slowing economic growth and straining household budgets. The RBA has signaled that controlling inflation remains its priority.
Inflation is expected to stay elevated until late 2027. Future decisions will depend on incoming data. Energy prices and AI-related investment remain key factors.
