Australia lifts rates to 18-year high as AI boom, energy costs fuel inflation

The Reserve Bank of Australia (RBA) increased its benchmark interest rate to 4.85%, the highest level in 18 years, amid surging technology costs from AI investment and higher energy prices. The central bank lifted its key rate by 25 basis points to 4.85% on Tuesday, warning that inflation would remain high throughout 2027 due to energy costs and AI-related investment fueling price pressures.

The Reserve Bank of Australia's monetary policy board voted 6-3 in favor of the hike, with three members opting to keep rates at 4.60%. The bank delayed its forecast for inflation to return to within its 2% to 3% target range until late 2027, about three-quarters later than initially expected. The RBA attributed the price increases to AI-related investment driving rapid growth in technology goods and higher fuel and commodity prices influenced by the Middle East conflict.

Australian Treasurer Jim Chalmers acknowledged the decision as widely anticipated but expressed difficulty for families and businesses grappling with the news. The move contrasts with the Federal Reserve's decision last week to keep rates unchanged, despite officials warning that AI investment is contributing to price pressures, affecting computer equipment and utilities.
