Australian Petrol Prices Poised for Up to 40-Cent Surge Amid Middle East Tensions

Global Oil Prices Surge Following Military Action

Australian petrol prices are anticipated to climb by as much as 40 cents per litre in the coming days and weeks, a direct consequence of recent military actions undertaken by the United States and Israel against Iran. These developments have significantly escalated tensions in the Middle East, leading to a sharp increase in global oil prices. Brent crude, a key international benchmark, has seen an 8 to 10 per cent surge, reaching approximately US$78 to US$79 a barrel, with intraday trading pushing above US$82. Analysts warn that prices could potentially exceed US$150 a barrel if the disruption persists.

Strait of Hormuz: A Critical Chokepoint

A primary factor driving the oil price hike is heightened concern over the security of the Strait of Hormuz. This narrow waterway, situated between Iran and Oman, is a vital shipping lane through which approximately 20 per cent of the world's oil supply passes daily. Reports indicate that Iran has responded to the military actions by effectively closing the Strait to shipping, resulting in a significant reduction in tanker traffic. Any disruption, or even the threat of one, in this critical chokepoint can cause global oil prices to jump rapidly.

Impact on Australian Motorists and Economy

The expected 40-cent per litre increase in Australia is based on a widely accepted rule-of-thumb: every US$10 rise in crude oil prices typically translates to an approximate 10 cents per litre increase at Australian fuel pumps. Motorists in major Australian cities, including Sydney and Brisbane, were already paying around $2 a litre for unleaded petrol on Monday morning, March 2, 2026, with some prices reaching as high as 213.9 cents per litre. These prices had yet to fully reflect the recent surge in crude oil. International crude price movements generally take 7 to 10 days, or up to two weeks, to be fully passed on to Australian bowser prices.

Broader Economic Implications

Economists are warning of broader economic consequences beyond the bowser. Higher petrol prices are anticipated to contribute to inflation, potentially adding 0.8 per cent to the Consumer Price Index (CPI). This inflationary pressure could influence future decisions by the Reserve Bank of Australia (RBA) regarding interest rates. While Australia imports over 90 per cent of its refined fuel, a significant portion is sourced from Singapore, which in turn receives oil from various regions including South Korea, Japan, Indonesia, Brunei, and Malaysia. Despite this diversification, the interconnected nature of global fuel pricing means that when international crude prices rise, wholesale costs increase, inevitably flowing through to local consumers.
