Six weeks after the outbreak of new conflict in the Middle East, global oil prices have doubled, triggering stark warnings from top Australian central bank officials that the country could face what many call the “central banker’s nightmare” — a toxic combination of rising inflation and slowing economic activity. The unfolding economic shock is already casting uncertainty over household finances and interest rate trajectories for Australian mortgage holders.\n\nReserve Bank of Australia (RBA) Deputy Governor Andrew Hauser outlined the grave risks during a public fireside chat with the Money Marketeers group in New York, speaking as national consumer sentiment indexes have slumped to all-time historic lows across Australia. While Hauser noted that weak sentiment readings do not always guarantee a corresponding drop in consumer spending, he cautioned that if the surveys accurately reflect underlying trends, Australia is heading for a significant income shock.\n\n“That is the central banker’s nightmare, you know, inflation up, activity down and judging the balance between the two is how we earn our money,” Hauser told the audience. This worst-case outcome, known as stagflation, creates an intractable policy dilemma for central banks: raising interest rates to curb inflation can further drag on already slowing growth, while cutting rates to stimulate activity can make soaring price pressures even worse.\n\nThe disruption to global energy markets from the Middle East conflict has already complicated the RBA’s long-running push to bring inflation back down to its target range of 2 to 3 percent, Hauser added. “I wouldn’t say we have high confidence that we’ve set interest rates at the right level because you never do have that high confidence. But we’re going to have to monitor this new shock pretty carefully,” he said. “I think it is easy to see that upside inflation pressure. More important for us now is to think through what the medium-term impact might be.”\n\nHauser emphasized that inflation is already “too high” in Australia, and the energy price spike spurred by the Gulf conflict is delivering a “big income shock for Australia” that ripples through every sector of the economy. The conflict has disrupted shipping through the Strait of Hormuz, the strategic global oil chokepoint that typically carries roughly one-fifth of the world’s daily oil trade, cutting off key supply routes for global energy markets.\n\nBefore the conflict began six weeks ago, benchmark oil traded at roughly $US56 per barrel; as of this week, prices hover around $US100 per barrel. For Australian motorists, this surge translates directly to higher fuel costs: every $US10 per barrel increase in oil prices adds approximately 10 Australian cents to the price of fuel at the pump, piling extra pressure on already stretched household budgets.\n\nPrior to the outbreak of conflict on February 28, Australia’s annual Consumer Price Index (CPI) fell 0.1 percentage points to 3.7 percent in February, but that figure still remained well above the RBA’s 2-3 percent target range. Already, federal Treasurer Jim Chalmers has updated the government’s economic modelling to account for worsening supply disruptions: early projections showed that prolonged fuel market disruption could push Australian inflation close to 5 percent, and Chalmers recently noted that even that grim forecast “look pretty conservative now.”\n\n“ We’ve asked for some more, challenging circumstances to be modelled,” Chalmers said. The two core variables shaping the government’s scenario planning, he added, are the duration of the conflict and how long it will take for global energy markets and the Australian economy to “get back on track after the hot part of hostilities.”\n\nWhile Hauser stopped short of predicting that Australia will enter a full recession, even with consumption already running at relatively low levels, financial markets are already bracing for further interest rate hikes. The RBA has already raised interest rates twice in 2025, pushing the official cash rate back to 4.1 percent — undoing two of the three rate cuts implemented in 2024, and leaving rates at their highest level since April 2012. As of the latest market pricing, investors see a roughly 65 percent chance of another rate increase when the RBA holds its next policy meeting in May, just one week ahead of the release of the federal government’s annual budget.
