Financial markets are pricing in a significantly higher risk of a Reserve Bank interest rate hike as escalating conflict in the Middle East pushes Brent crude oil prices toward $US90 a barrel. Traders have doubled the probability of a rate increase by November to 80%, according to ANZ, as rising fuel costs threaten to exacerbate Australia’s already high inflation.
The Link Between Middle East Conflict and Australian Interest Rates
The collapse of the ceasefire between the US and Iran has triggered a 23% surge in international Brent crude prices over the past two weeks. According to CBA chief economist Luke Yeaman, this energy shock risks creating a “stagflationary pulse” through the Australian economy. While the Reserve Bank has held rates steady, the combination of rising energy costs and persistent inflation is shifting market expectations.
Data from ANZ indicates that the likelihood of an interest rate hike on 12 August has risen to nearly 30%, up from 16% just two weeks ago. Markets are increasingly concerned that the Reserve Bank may be forced into a fourth rate hike to combat the inflationary pressure of higher global energy costs.

Diesel prices on the Australian east coast have climbed by 40 cents during July, reaching approximately $2.10 a litre, according to data from Motormouth. Diesel remains the fuel type most sensitive to global supply chain disruptions.
Oil Market Volatility and the Risk of $US150 Barrels
Global energy markets are currently at a “critical juncture,” according to ANZ senior commodity strategist Daniel Hynes. The threat of a blockade in the Red Sea and declarations of “full-scale war” have left analysts warning of a potential tipping point. Hynes noted that if current conditions persist, the $US100-a-barrel mark could be reached within weeks.
CBA’s Luke Yeaman warned that if the Strait of Hormuz remains closed for an extended period, global oil prices could climb as high as $US150 a barrel. However, Yeaman remains cautious about predicting multiple rate hikes, suggesting that if oil prices spike significantly, the government may intervene by reinstating fuel excise discounts to shield households.
Economic Growth Projections Amid Energy Shocks
The Australian economy is already showing signs of sharp deceleration due to previous interest rate hikes and a cooling housing market. Luke Yeaman has forecast economic growth to slow to 1.5% by the end of this year, down from 2.5% in 2025. A prolonged conflict in the Middle East could cause growth to slow even more aggressively.
Daniel Hynes highlighted that US oil inventories are already breaching technical limits, which will likely increase global competition for scarce seaborne cargoes. This structural fragility means that even a short-term resolution to the conflict is necessary to prevent long-term damage to global supply chains.
Keep an eye on the Brent crude benchmark as a leading indicator for local fuel prices. When global benchmarks surge, local pump prices typically follow within a one-to-two-week window.

- Why does the Middle East conflict affect Australian interest rates?
Rising oil prices increase inflation. When inflation remains too high, the Reserve Bank may raise interest rates to cool the economy, according to analysis from CBA and ANZ. - How high could oil prices go?
CBA’s Luke Yeaman warns that prices could reach $US150 a barrel in a worst-case scenario involving a prolonged closure of the Strait of Hormuz. - Is a rate hike guaranteed in August?
No. While market bets have increased to nearly 30%, economists like Luke Yeaman currently maintain forecasts for no further rate hikes this year, citing the potential for government intervention in fuel costs.
