RBA Rate Hike March 2026: Cash Rate 4.10%, AUD/USD Reaction and Outlook
RBA Hikes to 4.10%: AUD/USD Surges as Iran War Drives Australia’s Second Rate Rise in 2026
The Reserve Bank of Australia raised rates 25bps to 4.10% in a narrow 5–4 split decision — Australia’s second consecutive hike this year — as Iran war oil costs pushed inflation back into dangerous territory.

The RBA’s board voted five to four to lift the cash rate from 3.85% to 4.10% on Tuesday — the narrowest margin of the current tightening cycle and a decision that surprised markets expecting a cleaner majority. It is Australia’s second rate hike in 2026, effectively reversing all three cuts delivered last year.
The driving force was unmistakeable. Iran war oil prices above $100 a barrel have added materially to Australian fuel costs, threatening to push headline CPI above 4% before the RBA’s next quarterly forecast update. January CPI already sits at 3.8% — above the 2–3% target band. The board concluded waiting for more data carried more risk than acting now.
“It will be much worse if inflation gets built into the fibres — that will be a far worse outcome than the temporary pain we are asking households to accept today.”

The four who voted to hold were not doves. Bullock confirmed they still believe a hike is necessary — they simply preferred May over March. The market read the statement correctly: a unanimously hawkish board, regardless of the vote, means rates are going higher.
All four major banks — ANZ, NAB, Westpac, and CBA — immediately reaffirmed their May hike calls, pricing a further 25bps to 4.35% on 5 May. NAB went further, flagging a possible third hike in H2 2026 if Iran war inflation proves stickier than expected. For mortgage holders, today’s move adds approximately $160/month to a $1 million loan. Combined with February, 2026 has added up to $320/month to large mortgages.
Higher Australian rates vs a Fed on hold this week widens the rate differential in AUD’s favour. Key resistance: 0.7140. Key support: 0.7015. A break above 0.7140 opens 0.7200+. The Iran risk-off factor remains a competing downward pressure. Track live: FX Rate Live.
