The Reserve Bank of Australia (RBA) has increased its official cash rate by 25 basis points to 4.1%, the highest level in ten months. The decision, made on March 17, 2026, reflects growing concerns about persistent inflationary pressures, which have been intensified by the recent escalation of conflict in the Middle East. This is the second consecutive month the RBA has raised interest rates, following a similar hike in February.
The central bank's move comes as domestic price pressures, including a tight labor market and strong economic growth, were already pushing inflation above the RBA's preferred 2-3% target band. The US-Israeli attack on Iran, which led to the closing of the Strait of Hormuz, has further destabilized global energy markets and added to inflationary concerns. According to data from the Australian Bureau of Statistics, headline inflation rose 3.8% in the year to January.
RBA Governor Michele Bullock, in a press conference following the announcement, acknowledged the uncertainty surrounding the conflict's impact but emphasized the need to address rising inflation. "Middle East uncertainty was a big thing in [the board's] discussion," Bullock stated, adding that the risks to inflation are currently "more on the upside than downside for employment". She also noted that the decision to hike rates was not influenced by higher petrol prices alone.
The rate hike is expected to impact Australian households, with those holding a typical $600,000 mortgage facing increased monthly repayments. While the RBA's decision aligns with market expectations, some economists anticipate further rate adjustments depending on how the geopolitical and economic landscapes evolve. Other central banks, including the US Federal Reserve and the Bank of Canada, are expected to hold rates steady this week.
