Australia Inflation Cools in May, But Core CPI Keeps RBA Rate Hike Risks Alive

Australia’s inflation rate eased more than expected in May, offering signs that price pressures may be gradually cooling and strengthening the case for the Reserve Bank of Australia (RBA) to keep interest rates unchanged in the near term. However, underlying inflation remained elevated, highlighting persistent challenges for policymakers and keeping the possibility of further rate hikes on the table.

According to data released by the Australian Bureau of Statistics (ABS) on Wednesday, Australia’s Consumer Price Index (CPI) increased 4.0% year-over-year in May. The figure came in below market expectations of 4.3% and was also lower than April’s 4.2% reading.

Despite the softer headline inflation result, core inflation showed renewed strength. The trimmed mean CPI, a key measure of underlying inflation that excludes volatile items such as automotive fuel, rose 3.6% in May from 3.4% in the previous month. This remains above the RBA’s target range of 2% to 3%, suggesting that inflationary pressures are still present within the economy.

Electricity prices were a major driver of inflation during the month, climbing after state and federal government energy rebates expired. Meanwhile, lower global oil prices and a temporary reduction in Australia’s fuel excise helped ease fuel-related inflation.

The latest inflation data arrives as the RBA evaluates the impact of recent monetary tightening measures. The central bank raised interest rates by a total of 75 basis points earlier this year in response to a resurgence in inflation but opted to leave rates unchanged at its June meeting.

Economists believe the persistence of core inflation could encourage the RBA to maintain a hawkish stance. Analysts at Capital Economics noted that stronger underlying price pressures suggest the battle against inflation is not yet over. They argue that an additional 25-basis-point rate increase remains a realistic possibility as insurance against future inflation risks.

For financial markets, the inflation outlook remains a key factor influencing the Australian dollar (AUD/USD), interest rate expectations, and broader economic sentiment. While headline inflation is showing signs of moderation, stubborn core inflation may continue to shape RBA policy decisions in the months ahead.
