Australia's Reserve Bank raised the official cash rate to 4.10 per cent on 17 March in a decision that split its board like few in recent memory. Five members voted to increase; four voted to hold at 3.85 per cent. That narrow majority sends a signal louder than the rate rise itself: Australia's central bank is deeply uncertain about whether the path ahead leads to controlling inflation or walking into recession.
For households, the message is more immediate and painful. The increase adds roughly $120 a month to repayments on an average home loan of $736,000. For a mortgagee with 30 years remaining, their monthly repayment rises to $4,410. Banks moved swiftly to pass the hike through. Commonwealth Bank, NAB, Westpac, and ANZ all raised their variable rates by the full 0.25 per cent, effective from late March.
The RBA's reasoning is familiar. Inflation picked up in the second half of 2025, rising above the target band of 2-3 per cent. The labour market has tightened. Demand is outstripping supply. Added to this, petrol prices have spiked because of conflict in the Middle East, pushing inflation expectations higher still. Under normal conditions, raising rates would be straightforward.
But the conditions are not normal. Governor Michele Bullock has essentially acknowledged what the divided vote makes plain: inflation and recession are now in direct tension. When asked whether the combination of rate rises and high petrol costs would push Australia into recession, Bullock said bluntly that the RBA would accept that possibility if it was necessary to bring inflation down. "We don't want to have a recession," she said, "but if it's hard to get inflation down, then we're going to have to deal with that possibility."
This is the governing trade-off the four dissenters appear to have rejected. They may have believed that further rate increases, when energy prices are already doing the RBA's tightening work, risked unnecessary harm to the labour market and consumer spending. They may have judged that inflation expectations, though rising, will eventually settle without pushing rates higher still.
The split decision reveals a genuine economic dilemma, not a simple error. Australia's policymakers face a choice between two painful outcomes. What it does not reveal is consensus about which pain is preferable. The banks are divided too. ANZ and NAB have publicly forecast another 25-basis-point hike in May. Others are less certain. For mortgage holders watching their costs rise and economic growth cloud over, the RBA's institutional disagreement offers no comfort. What matters now is whether Bullock's willingness to countenance recession proves proportionate to the inflation threat, or whether Australia's central bank has begun a tightening cycle that will prove unnecessarily harsh.
