Oil at $113 adds $36 to Australian fuel tanks

The global benchmark oil price reached US$113 per barrel overnight, a figure that translates directly into higher costs for Australian households. Motorists are now paying 60 cents more per litre than they did before the US and Israel launched their attacks on Iran. For a family that refuels weekly, this increase adds $36 to the cost of filling a standard 60-litre tank. Over a month, that amounts to $144 in additional expenses compared with February.

The surge in energy costs is the primary factor behind a darkening economic outlook for Australia. Treasury officials are currently lowering their growth forecasts ahead of the December mid-year budget update. Slower economic expansion and higher unemployment rates are now expected outcomes of the current conditions. This shift marks a departure from earlier optimism. Last week, Treasurer Jim Chalmers suggested the economy would be slightly better in a year. By Friday, he was acknowledging that the official projections were being revised downward.

The central cause of this pressure is the widening conflict in the Middle East. The International Monetary Fund issued warnings earlier this month about the potential for further escalation. Analysts at Westpac have outlined a scenario where oil prices head toward US$150. The New York Times reported overnight that the US and Israel have drawn up plans to resume attacks on Iran after the American midterm elections. Such an escalation would have major consequences for inflation and interest rates. A fifth rate rise is possible on 3 November.

Global financial markets are also showing signs of stress. Investors are growing uneasy about the sharp rise in debt among companies building artificial intelligence infrastructure. This anxiety triggered a steep sell-off on Wall Street overnight. Heavy spending on AI has helped mask weakness elsewhere in the global economy, but the sector is now under scrutiny. Community opposition to new datacenters could further slow the build-out, adding to short-term economic stress.

Reserve Bank governor Andrew Hauser described the combination of high inflation, low growth, and rising unemployment as a central banker's nightmare. This difficult position creates a dilemma for Treasurer Jim Chalmers, who is in need of a public win. Chalmers told Politico that the pressures on people right now are very substantial and that the situation keeps him awake at night. He noted that the government is hostage to decisions made in Washington, Tehran, and Eastern Europe, where two wars are pushing up inflation and weighing on growth globally.

Domestic factors compound the external pressures. High government spending works against the fight against inflation, a point the opposition raises frequently. Productivity growth is stagnant, meaning the economy reaches its speed limit sooner and inflation runs higher at lower rates of growth. The government faces a set of hard choices, each carrying a distinct cost.

One option is to cut the fuel excise again on a temporary basis to lower petrol prices. This would put billions of dollars back into motorists' pockets but would make it harder for the Reserve Bank to rein in inflation. Alternatively, the Labor government could announce large spending cuts in the December update. This would assist the central bank but would weigh on an already weak economy and push unemployment higher. It is unclear whether such austerity would earn the government credit with voters.

The next major economic signal is scheduled for the December mid-year budget update. Treasury officials will present the revised forecasts at that time. The Reserve Bank's rate decision is set for 3 November. The outcome of these events will determine the immediate trajectory of the Australian economy.
