RBA Delivers Third Consecutive Hike

The Reserve Bank of Australia raised its cash rate by 25bps to 4.35% at its May 2026 meeting, in line with expectations. This marks the third straight hike this year and, in an 8–1 vote, fully unwinds last year’s easing cycle. The decision reflects a material pickup in inflation in H2 2025, which continues to feed into price pressures in 2026. The Bank noted that the earlier rise was driven by stronger capacity constraints in the economy, while higher fuel and commodity prices linked to the Middle East conflict added to inflationary pressure. Updated forecasts show inflation peaking higher than expected before easing as demand slows and capacity pressures fade. The outlook remains uncertain, with risks skewed to the upside if geopolitical tensions persist and lift energy prices, feeding broader inflation. The Board judged inflation likely to remain above target, warranting the increase, and reiterated a data-dependent approach.

Australia faces a difficult macro backdrop, with elevated inflation and limited supply capacity raising stagflation risks if energy shocks persist. In a fireside chat, RBA Deputy Governor Andrew Hauser warned of the “nightmare” scenario where inflation accelerates even as growth weakens, complicating policy choices. He noted inflation remains too high, while supply constraints limit the economy’s ability to absorb shocks. A key concern is surging energy prices tied to the Middle East conflict, which Hauser described as a major income shock. Rising costs are eroding household purchasing power and lifting business expenses, threatening growth. At the same time, the RBA is focused on anchoring inflation expectations, cautioning that second-round effects could entrench price pressures. This mix of weak growth risks and persistent inflation leaves the central bank with little scope to ease, reinforcing the need to keep policy restrictive.

Australia’s inflation remains elevated, with excess demand persisting, according to the Reserve Bank’s March minutes. Rising oil prices, driven by Middle East tensions, were flagged as a key near-term inflation driver, lifting short-term expectations, though longer-term ones stayed anchored. Higher energy costs are expected to weigh on growth domestically and globally, though the scale of impact is uncertain. Policymakers noted financial conditions have tightened slightly but questioned how restrictive current settings are. Most members judged further rate hikes likely necessary to return inflation to target, as risks tilt upward. Supply constraints could worsen amid geopolitical developments, adding pressure. Yet demand outlook remains unclear, given Australia’s energy-export role and resilient household balance sheets. Members estimated that if oil prices hold near USD 100 per barrel, headline CPI could rise to about 5% in the June quarter.
