The RBA Meets Today With $104 Oil, 5.2 Per Cent Inflation Expectations, and No Good Options
The Reserve Bank board sits down today to decide what to do about interest rates. The answer, according to 23 of 30 economists surveyed by Reuters and all four major banks, is a 25 basis point hike to 4.10 per cent. Cash rate futures put the probability at 75 per cent.
On paper, that makes this the most predictable RBA meeting in months. In reality, it might be the most consequential one in years. Because the decision being made today is not really about one quarter point. It is about whether Australia's central bank believes the fuel crisis reshaping household budgets across the country is a temporary shock or the beginning of something that changes the inflation outlook for years.
The Numbers Driving the Decision
Start with what the board already knows.
Headline inflation in January came in at 3.8 per cent, well above the 2 to 3 per cent target band. Trimmed mean, the measure the RBA watches most closely because it strips out volatile items like fuel, ticked up to 3.4 per cent from 3.3 per cent in December. Both numbers are moving in the wrong direction.
Then there is the number that will have kept the board up last night: consumer inflation expectations hit 5.2 per cent in March, the highest reading since July 2023. That is exactly the kind of figure that makes central bankers reach for the rate lever. When people expect prices to keep rising, they demand higher wages, businesses raise prices pre-emptively, and inflation becomes self-fulfilling. The RBA's entire framework is built around preventing that spiral.
Deputy Governor Andrew Hauser said on March 10 that the February oil price jump would push inflation "above the 4.2 per cent forecast" from the February Statement on Monetary Policy. He warned of "a very genuine debate" at the March meeting and stressed the danger of under-reacting. Markets repriced a March hike immediately after those comments.
Governor Michele Bullock was even more direct on March 3, saying she is "very alert" to inflation risks from the Middle East conflict and that "every meeting is live." In RBA language, that is about as close to pre-announcing a hike as a governor gets without actually doing it.
Why Fuel Is the Problem That Will Not Go Away
Automotive fuel carries a 3.3 per cent weight in the CPI basket. On its own, that sounds modest. But fuel is not like other prices. When petrol goes up 50 cents a litre, it does not just make driving more expensive. It makes everything that moves by truck more expensive. Groceries, building materials, farm inputs, online deliveries. The second round effects of an oil shock flow through the economy over months, not days.
Across the more than 8,000 stations we track at Petrolmate, national unleaded averages sit between 229 and 253 cents per litre depending on the state. Diesel, which is what actually moves the freight network, is averaging 268 to 274 cents. The Australian Trucking Association has warned that diesel above 210 cents triggers industry wide freight rate renegotiations. We are 60 cents past that line.
The National Farmers' Federation has warned food prices could rise by up to 50 per cent. Even if that number proves conservative, any material increase in food costs flows directly into CPI and directly into the inflation expectations the RBA is trying to anchor.
Brent crude closed last week at $104 a barrel, up from $72 before the Strait of Hormuz effectively closed on February 28. Oil analysts expect prices to remain above $95 for at least two months. If the strait does not reopen, there is no obvious ceiling.
The Central Banker's Dilemma
Here is what makes today's decision genuinely difficult, and why it matters beyond the usual rate watch commentary.
The textbook says you do not tighten monetary policy into a supply shock. When oil prices spike because of a geopolitical event, that is not demand driven inflation. Raising rates does not create more oil. It does not reopen the Strait of Hormuz. It does not build tankers or refineries. What it does is slow an economy that is already being squeezed by higher energy costs, hitting households with a double blow: more expensive fuel and more expensive mortgages.
That is the argument for holding.
The argument for hiking is that the RBA does not have the luxury of theory right now. Inflation expectations at 5.2 per cent are a clear warning. If those expectations become entrenched, if workers start demanding wage increases to offset fuel costs, if businesses start pricing in sustained energy inflation, then the temporary shock becomes permanent. And unwinding entrenched inflation is far more painful than preventing it.
The February hike was the RBA's way of saying it takes the risk seriously. A March hike would say it is willing to act even when the cause of inflation is beyond its control, because the consequences of inaction are worse.
All four major banks, CBA, Westpac, NAB, and ANZ, now forecast at least two more hikes after today, taking the cash rate to 4.35 per cent by mid year. Westpac and NAB have flagged the possibility of three consecutive hikes. Bond markets are pricing a terminal rate that could reach 4.60 per cent. The 10 year government bond yield has pushed to nearly 5 per cent, the highest since 2011.
What Other Central Banks Are Doing
The RBA is an outlier. The US Federal Reserve is expected to hold rates steady this week, having paused its cutting cycle to assess the oil shock. The European Central Bank meets on March 19 and is also expected to hold. The Bank of England is in wait and see mode. None of them are actively hiking.
That makes the RBA the most aggressive major central bank in the world right now. Whether that is courageous or reckless depends entirely on how the next three months play out.
If oil falls back below $80 as the IEA's reserve release takes effect and diplomatic efforts gain traction, the RBA will look like it overreacted, raising rates into a temporary shock that was already fading. Mortgage holders will have paid the price for nothing.
If oil stays above $100 and second round effects push trimmed mean inflation above 4 per cent, the RBA will look prescient. Early action will have prevented a worse outcome.
The honest answer is that nobody knows which scenario unfolds. The RBA is making a judgment call under genuine uncertainty, and it is choosing to err on the side of fighting inflation rather than supporting growth.
What This Means for Households
For a household with a $600,000 mortgage on a variable rate, a 25 basis point hike adds roughly $95 a month to repayments. Combined with the fuel increases since late February, a typical family is looking at $150 to $200 a month in additional costs between the rate hike and the petrol spike.
That is real money. For families in Western Sydney, outer Melbourne, or SE Queensland, where long commutes mean higher fuel bills and larger mortgages mean higher rate sensitivity, the combined hit is significant.
The practical response remains the same as it has been since the crisis began: track fuel prices, fill up at cycle lows, use tools like Petrolmate to find the cheapest stations in your area, and avoid panic buying. At current price spreads, choosing the right station in your suburb can save $15 to $20 per fill. That will not offset a rate rise, but it helps at the margins.
The Bigger Picture
Today's decision will be announced at 2:30 PM AEDT. The press conference that follows will matter more than the number itself. What the market wants to hear is whether the RBA sees this as a one-off adjustment or the beginning of a sustained tightening cycle. The language around "further action" and "data dependent" will be parsed to the syllable.
But beyond the market mechanics, today's meeting represents something worth paying attention to. The RBA is being forced to make a call on a question that has no clean answer: when a geopolitical shock sends fuel prices surging in a country that imports 90 per cent of its fuel, is the right response to tighten financial conditions further, or to accept temporarily higher inflation and protect household budgets?
Every major central bank in the world is wrestling with some version of that question right now. Australia, because of its uniquely exposed fuel supply chain and its already elevated inflation, is the first to answer it with action rather than words.
We will be tracking fuel prices across every state as the market digests today's decision. If history is any guide, servo pricing tends to drift higher in the days following a rate announcement, regardless of whether the fuel cost has actually changed. Keep an eye on your local prices and fill up before the cycle turns.
