Petrol Relief Ends as Oil Hits $100: Double Hit at the Bowser

Australian motorists are bracing for a sharp rise at the pump after Brent crude oil broke through the US$100-a-barrel mark, colliding almost perfectly with the scheduled end of the federal government's petrol excise relief on 2 August. The convergence of the two events risks delivering one of the steepest single-week price jumps drivers have experienced in years.

Dr Christian Bayliss, founder of Fort Lake Asset Management, described the timing as deeply unfortunate. "We're going to see this double jump come through," he told 7NEWS, pointing out that the crude price has climbed rapidly from around US$70 just weeks ago — a move that caught many economists off guard. "They were just not expecting oil to stay so elevated for so long," he said.

The sustained high price is no longer contained to forecourts. Bayliss flagged that the ripple effect is already working its way into everyday grocery bills. Fertiliser costs are rising in step with oil, and critically, one third of the world's seaborne fertiliser passes through the Strait of Hormuz — a route that remains under pressure from ongoing Houthi attacks in the Red Sea. Fresh food prices are among the first to feel that squeeze, and a 5 per cent round of minimum wage increases is adding further upward pressure on retail prices across the economy.

On top of the oil shock, Australia this week received confirmation that US tariffs on its exports have been lifted from the 10 per cent interim rate to 12.5 per cent. However, Bayliss offered some measured reassurance on that front. Australia's export economy is oriented primarily toward manufacturers such as China — iron ore being the most prominent example — rather than finished goods shipped directly to American consumers. "We are reasonably unaffected as an economy compared to those others sitting on the 12.5 per cent," he said, noting the country is partly insulated by the structure of its trade flows.

The picture on domestic fuel security is more stable. Australia currently holds around 46 days' worth of petrol stocks, which provides a short-term buffer. The catch is structural: the country imports between 80 and 90 per cent of its oil and is therefore fully exposed to global spot prices. "If we produced all of our own oil, we would be somewhat immunised," Bayliss said. "But the fact is, we are reliant on global markets." Asked how high prices could climb in a worst-case scenario, he put a ceiling of around US$150 a barrel on the table while stressing he considered that outcome unlikely, provided the Middle East situation does not deteriorate further.

The fuel crunch feeds directly into next week's critical Reserve Bank of Australia deliberations. Wednesday's Consumer Price Index release will be the pivotal data point ahead of the August interest rate decision. While headline inflation is broadly expected to ease slightly — dropping from 4 per cent to approximately 3.8 per cent — the trimmed mean figure, which the RBA uses as its core inflation gauge, is forecast to move in the opposite direction. That divergence, driven in part by persistently high energy costs seeping into services and food, means a rate rise remains firmly on the table.

Bayliss put the probability of an August hike at roughly 50-50, but cautioned mortgage holders to plan for at least one more increase before year's end. "This elevated oil price is creeping into all of these parts of life that we didn't think it was going to," he said. For households already stretched by rising rents, grocery bills and borrowing costs, the coming weeks look set to test budgets even further.
