Oil Price Shock: Iran Conflict's Impact on Global Economy | Financial Markets Analysis (2026)

Financial markets brace for oil price shock and economic fallout as Iran conflict escalates

The world is on edge as oil prices are set to skyrocket when commodity markets open tomorrow, with reports indicating that the air war between the US, Israel, and Iran has effectively closed the Strait of Hormuz to shipping. This critical shipping route, connecting major oil producers in the region to the global market, is at the heart of the escalating conflict.

The region, encompassing Saudi Arabia, Iraq, Iran, the UAE, Kuwait, Qatar, Bahrain, and Oman, is a powerhouse in oil production, contributing 27% of the world's crude oil. A staggering three-quarters of this production, equivalent to a substantial 20% of the global oil supply, transits through the Strait of Hormuz.

While no single country holds exclusive control over the Strait of Hormuz, Iran's military presence poses a significant threat. With the ability to exercise sovereignty within 12 nautical miles of its coastline, Iran can restrict shipping at the narrowest points, potentially causing widespread disruption.

Vessels in the area have received radio alerts, confirming the closure of the Strait of Hormuz. The UK Maritime Trade Operations agency and the US Department of Transportation Maritime Administration have issued warnings, urging vessels to avoid the area. Reuters reports that major oil companies and trading houses have halted crude oil, fuel, and liquefied natural gas shipments through the Strait of Hormuz, following Iran's declaration of closed navigation.

The implications are dire. One industry executive predicts that ships will remain stationary for days, while satellite images show vessels backed up near major ports. The conflict's impact on oil prices is expected to be severe, with analysts forecasting a sharp spike, potentially surpassing $100 per barrel, from the current $67 for West Texas crude.

The duration of the conflict is a critical factor. A prolonged dispute could cause more significant economic damage, according to experts. The 2022 Russia-Ukraine invasion led to a similar oil price surge above $120 per barrel, but this conflict's potential impact is heightened due to the involvement of key oil-producing nations.

Economists advise Australians to fill their tanks, as a $10-barrel increase could translate to a 10-cent-per-litre rise in petrol prices, resulting in a 40-cent increase from the current $67 per barrel.

The conflict's immediate effects on the Australian economy are uncertain. While disruptions to oil supplies from the Middle East to China could harm China's economy and its imports from Australia, the region also exports a significant portion of the world's liquefied natural gas (LNG) through the Strait of Hormuz. This dual impact on LNG prices could be a double-edged sword for Australia, affecting both domestic gas prices and the country's role as an LNG exporter.
