RBA Interest Rate Hike Likely as US-Iran War Drives Fuel... 2026

The likelihood of an RBA interest rate hike has doubled amid the escalating US-Iran conflict and surging fuel prices. Market forecasts now place a nearly 30% chance of a rate rise on 12 August, up from 16% two weeks ago, as global oil reserves dwindle and the Middle East crisis deepens.

How the US-Iran War Is Driving Fuel Prices Higher

The breakdown of the fragile ceasefire between the US and Iran has sent the international Brent crude benchmark soaring by 23% over the past two weeks, bringing it within reach of $US90 a barrel. Experts warn the global energy market is at a critical juncture. Australian motorists face climbing fuel costs, with diesel jumping 40 cents to about $2.10 per litre in major east coast cities, according to Motormouth. Unleaded petrol has risen 25 cents to around $1.75, partly due to the removal of federal fuel excise relief.

Market Reactions and Stagflation Concerns

Traders have upped bets on a fourth RBA rate hike as inflation remains stubbornly high. Luke Yeaman, CBA’s chief economist, noted that a total lack of trust between warring parties makes it difficult to judge the conflict’s trajectory. “In the current dynamic, we believe this will drag on for at least several weeks and possibly longer,” Yeaman said. He warned that the situation would send a fresh stagflationary pulse through the Australian economy, combining slow growth with rising prices.

Key Data Points: Fuel Price Surge

Global oil stockpiles are already depleted. Iran’s leader has declared “full-scale war” with the US, and Houthi rebels threaten to blockade Saudi Arabian oil passing through the Red Sea. Analysts warn of a coming tipping point that could send fuel prices even higher.

What This Means for Australian Households

Higher fuel costs ripple through the economy, increasing transport and production expenses. If the RBA raises rates, mortgage holders will face higher repayments, squeezing household budgets. The combination of rising energy prices and potential rate hikes creates a challenging environment for consumers and businesses alike.
