RBA raises cash rate to 4.35%; Bullock warns further hikes possible

The Reserve Bank of Australia (RBA) increased its official cash rate by 25 basis points to 4.35% at the May Monetary Policy Board meeting. The Board said the move was intended to address persistent inflationary pressures and maintain the RBA’s commitment to returning inflation to the 2–3% target band.

In its statement, the RBA highlighted a recent spike in fuel and related commodity prices as a significant near-term driver of inflation, noting the risk of second-round effects across goods and services. Governor Michele Bullock remarked that the rate rises to date aim to reduce demand and restrain price- and wage-setting behavior, and that further increases could be necessary if elevated energy costs continue to feed through to broader inflation. The Board’s decision was taken by a majority vote.

Markets reacted promptly: the Australian dollar strengthened and government bond yields rose as investors priced in the higher policy rate and the risk of additional tightening. Mortgage borrowers face heightened borrowing costs, and several economic commentators noted that while some forecasters expect a pause to assess the cumulative policy impact, others point to upside inflation risks that could compel the RBA to act again.

The rate rise comes against a backdrop of elevated global energy prices and geopolitical tensions that have pushed fuel costs higher, creating an extra inflation impulse beyond domestic demand-side pressures. The RBA’s May Statement on Monetary Policy updated its projections and signalled a higher path for the cash rate through the year compared with earlier forecasts, reflecting these persistent upside risks.

Analysts say the RBA will monitor incoming inflation and labour market data closely; a period of data-dependent pause is possible, but the central bank has not ruled out further tightening if inflation proves more persistent. Market attention will centre on CPI releases, wage outcomes and oil price movements as key determinants of the policy outlook. Institutions and investors are preparing for a scenario in which the RBA maintains a moderately restrictive stance until clear evidence of a durable disinflation trend emerges.
