The Reserve Bank of Australia raised the official cash rate from 3.85 per cent to 4.10 per cent at its second board meeting of the year, placing the central bank on a collision course with Australian household budgets as it battles inflation driven largely by the Middle East conflict and rising fuel costs.
The decision marked the board's first non-unanimous decision since July last year, decided by just a single vote, with five members voting to increase the rate and four voting to leave it unchanged. The split reveals genuine tension within the central bank over the right policy path given the extraordinary circumstances: information since February indicated increases in inflation reflected greater capacity pressures, and the conflict in the Middle East had led to sharply higher fuel prices that, if sustained, would add to inflation.
RBA Governor Michele Bullock acknowledged that while the bank does not want to have a recession, that was not out of the question if inflation proved hard to get down. This candid admission frames the predicament facing Australian policy makers: they face genuine economic trade-offs with no clean solution in sight.
The household squeeze intensifies
A 25-basis point increase on an average $700,000 home loan will see repayments rise by about $115 per month, coming on top of an interest rate increase from the February meeting which saw average home loan repayments rise by around $110 per month. This means Australian households are confronting cumulative pain: the average family will be paying an additional $225 monthly just from rate rises in the first quarter of 2026.
But the pressure extends far beyond mortgages. The average Australian household with a mortgage and at least one car is almost $75 per week worse off than they were six weeks ago, with fuel price hikes creating a sudden hit to household budgets. Unleaded fuel in Sydney is currently averaging 229c/L compared to 180.4c/L in the last quarter of 2025, meaning families are spending an additional $25.80 per week on fuel alone.
Two of Australia's big four banks, ANZ and NAB, have restated their belief there will be another cash rate increase in May to 4.35%, with ANZ saying this should mark the end of the current tightening cycle. This provides some reassurance that further rises may not be indefinite, though if another hike occurs in May it would be the first time the interest rate has been hiked at three consecutive meetings since March 2023.
The inflation-recession dilemma
The central bank faces a genuine policy bind. Inflation was already too high before the Middle East conflict, reflecting demand outstripping supply. Yet the conflict causes prices to rise at the same time as it pushes down economic growth, a stagflationary event; this differs from post-pandemic inflation spikes where strong growth could absorb rising prices without severe economic damage.
January headline inflation sat at 3.8%, well above the RBA's target band of 2-3%. Treasurer Jim Chalmers warned inflation may climb towards five per cent should the Iran war and blockade on the Strait of Hormuz drag on. Yet the Treasurer said a recession is not something the government is anticipating or expecting, stating that federal modelling shows it expects a hit to growth but not the kind of dramatic contraction of an economic crash.
This optimism deserves scrutiny. According to Westpac, a one-month disruption to supply from the Strait of Hormuz would lift Australia's Consumer Price Index by around one percentage point with GDP growth 0.2 percentage points lower, while a three-month disruption could see the CPI spike by 1.5 percentage points with GDP 0.5 percentage points lower by the end of 2026. The economic mathematics of a prolonged Middle East conflict remain uncertain.
The RBA said it will be attentive to the data and evolving assessment of the outlook and risks, paying close attention to developments in the global economy and financial markets, trends in domestic demand and the outlook for inflation and the labour market, as monetary policy is well placed to respond to developments. In practice, this means further moves in either direction remain possible depending on how global energy markets evolve.
Competing claims and reasonable disagreement
The policy debate contains genuine intellectual merit on both sides. Those supporting the March hike argue that there is a material risk that inflation will remain above target for longer than previously anticipated, requiring early action before inflation expectations become entrenched. Coalition Treasury spokesperson Tim Wilson argued that Australia's inflation problem was reported in the December data from Canberra rather than created by international factors, suggesting that tighter policy is warranted regardless of external shocks.
Conversely, the four board members who voted against the hike appear to have believed that they considered whether to hold off until May, with those voting against still feeling a need for an eventual rate rise but disagreeing on timing. Their view likely reflected concern that raising rates during an oil price spike driven by supply constraints, rather than demand pressures, may choke off growth without effectively controlling prices.
These are not partisan positions. They represent different answers to a genuinely difficult question: when faced with inflation driven simultaneously by domestic demand pressures and external supply shocks, does tightening monetary policy reduce inflation without causing unnecessary economic damage?
Looking ahead
The next decision arrives in May, and a second hike appears increasingly likely. Markets are now pricing nearly three rate increases across 2026, meaning the cash rate could rise substantially from current levels. Three more rate rises in total across 2026 would see the RBA cash rate hit a 15-year high of 4.6 per cent and add $361 to monthly repayments on an average new mortgage of $736,000, totalling $4,332 in extra annual repayments.
Yet the outlook hinges entirely on developments beyond Australia's control. Commodity prices, including oil, remain volatile amid geopolitical uncertainty, which is one reason the outlook can shift quickly. If the Middle East conflict resolves quickly, energy prices stabilise and inflation moves back towards target, the RBA may pause. If disruption persists, further hikes remain likely. Australian policy makers and households alike are now hostages to events in Tehran and Washington.
