When the Reserve Bank of Australia last moved on interest rates two months ago, it caught many observers off guard. The February rise to 3.85 per cent marked the first hike in roughly two years, reversing course after three cuts delivered the previous year. That decision signalled the end of the easy-money chapter and the start of a much harder one.
Today's board meeting brings the RBA to a genuine crossroads. The board enters its March 17 meeting with no clear consensus on rates, with Deputy Governor Andrew Hauser acknowledging that policymakers face a genuinely divided decision shaped by conflicting economic signals at home and growing instability abroad.
At first glance, the case for another hike looks straightforward. Australia's economy expanded 2.6% over the past year, the fastest pace in nearly three years. That strength reinforces concerns that growth is running above the RBA's estimated sustainable level. More problematic still, underlying inflation came in at 3.4% for the December quarter, and the RBA doesn't expect it to fall back within the 2 to 3% target band until early 2027.
The geopolitical backdrop has shifted the calculation dramatically. Oil prices spiked above US$100 a barrel as conflict in the Middle East raised fears about disrupted shipping routes, jumping from mid-60s levels six months earlier. For an import-dependent economy, this matters. Australia imports more than 90 per cent of the fuel we use, and it is priced in US dollars.
Treasurer Jim Chalmers warned that Australian households are likely to face increased cost-of-living pressures, with inflation potentially peaking somewhere between the mid-to-high fours. Some analysts have flagged even steeper scenarios. National Australia Bank projected that Australia's inflation rate could climb as high as 5 per cent in the second quarter of 2026.
Yet the argument for holding rates steady carries real force too. Weaker-than-expected consumer spending and softer labour cost figures point to an economy already feeling the strain of previous rate increases, and acting too aggressively risks tipping Australia into a sharper slowdown, driving up unemployment and ultimately pushing inflation below target. Household consumption grew just 0.3% for the quarter, suggesting the consumer is already feeling pressure.
The path of oil prices adds another layer of complexity. Higher oil prices can lift some prices, but they can also leave households with less spare cash to spend elsewhere, which can soften demand in other parts of the economy. Iran's blockade of the Strait of Hormuz is stopping crude oil from the Gulf states reaching the Asian refineries that supply 80 per cent of Australia's petrol, diesel and jet fuel. This supply shock differs from demand-driven inflation, yet demands a monetary response nonetheless.
The economic stakes are material. A rate hike would be the second of the year, meaning if you have a million-dollar mortgage, you are handing over an extra 317 dollars per month. For households already stretched on fuel and grocery bills, another rise threatens to compress spending further.
What the RBA ultimately decides matters less than what it signals about the road ahead. Several major banks now expect a follow-up 25 basis point hike in May, potentially bringing the terminal rate to 4.35 per cent. Some remain cautious. Among economists providing forecasts beyond the March meeting, 17 of 27 expect rates to reach 4.35% by the third quarter, while others see the policy rate peaking at 4.10%.
The fundamental tension is unresolved. Australia faces genuine inflation that requires restraint, yet it is being driven partly by forces beyond the RBA's control—a Middle East conflict that threatens energy security, a tight labour market inherited from an earlier expansion, and an economy still running hot. Rate rises alone cannot fix a global oil shock. Neither can the central bank afford to ignore inflation expectations unanchoring on the back of soaring fuel prices.
Whether the board moves today or waits until May, the economic pain is real. Households are already under pressure. Businesses face margin squeeze. The question is not whether rates will need to rise; it is how fast, how far, and whether the RBA can achieve the narrow path between reining in inflation and tipping the economy into avoidable recession. Inflation is not expected to return toward the middle of the target band until 2028. That timeline alone speaks to the grinding challenge ahead.
