Australian Households Brace for Rate Hike and Petrol Prices Above $2

Australian households are bracing for a potential double whammy of financial pressures in the coming weeks: a possible interest rate hike from the Reserve Bank of Australia (RBA) and petrol prices soaring above $2 a litre. This comes as economists warn of the escalating Middle East crisis pushing global crude oil prices back above $US100 a barrel. Financial markets are now pricing in a significantly increased probability that the RBA board will deliver a fourth cash rate increase at its next meeting on August 11.

The RBA's cash rate currently stands at 4.35%, having seen three consecutive increases totaling 0.75 percentage points since February 2026. The bank's next monetary policy decision is scheduled for Tuesday, August 11, 2026. Market expectations are divided, with most major banks like Commonwealth Bank (CBA), National Australia Bank (NAB), and Australia and New Zealand Banking Group (ANZ) anticipating a hold. However, Westpac is an outlier, forecasting a 25 basis point increase in August. A survey of economists by Finder revealed that 55% expect at least one further hike in 2026, with 62% of that group nominating August as the most likely timing.

The surge in petrol prices is primarily driven by the escalating Middle East crisis, stemming from the US-Iran war. This conflict, coupled with Houthi threats in the Red Sea and tensions in the Strait of Hormuz, is disrupting global oil supplies. Brent crude, which had peaked at $126 a barrel in April and eased to $71 in early July, has now climbed back above $100. Warwick McKibbin, director of the ANU's Centre for Applied Macroeconomic Analysis, stated that crude oil prices are likely to remain elevated for “at least a year” as the US-Iran war enters a more dangerous phase. Adding to the pressure, the Australian government's fuel tax relief is set to be fully phased out from August 2, adding another 16 cents per litre to fuel costs.

These developments are poised to have significant repercussions for the Australian economy. Elevated oil prices fuel inflationary pressures by increasing transport, freight, and overall household costs. This situation complicates the RBA's efforts to bring inflation back within its target range of 2-3%. Despite stronger-than-expected job growth in June, with 76,300 new positions added, the unemployment rate held steady at 4.4%, presenting a complex picture for the RBA's monetary policy deliberations. Rising inflation concerns are also reflected in Australian government bond yields, which have climbed close to 15-year highs.

The global energy market is at a critical juncture due to geopolitical tensions in the Middle East. Fatih Birol, head of the International Energy Agency (IEA), cautioned that while global oil markets have benefited from “cushioning factors” so far, there is no room for complacency amid escalating hostilities. Analysts warn that oil prices could reach $120 a barrel by year-end if exports via the Strait of Hormuz do not restart. This scenario could increase the risk of stagflation for global economies and lead to prolonged high energy costs.

Analysts and market participants are closely monitoring key data that will influence the RBA's August decision. The June-quarter inflation figures, in particular, will play a crucial role in shaping the RBA's monetary policy stance. Should inflation persist above the RBA's target range, the likelihood of a rate hike will strengthen. The ability of households to cope with intensifying cost-of-living pressures and potentially higher borrowing costs will be a significant factor in determining the smoothness of the economic adjustment. Economists caution that a combination of heightened cost-of-living pressures and another rate hike could create a challenging situation for a segment of households.
