Global oil prices edged modestly lower in Wednesday afternoon trading, remaining nearly 10% higher than before Israel’s first attack on Iran last week, as investors look for evidence of supply disruption in crude markets as the conflict enters its sixth day.

This surge reflects the market's concerns regarding the disruption of oil supplies from the Persian Gulf region. The Strait of Hormuz, a strategic passage that separates Iran and Oman, is a major route for global oil shipments, with approximately 20 percent of the world's total oil supply passing through the strait daily.

Despite not relying on Iran for its oil supplies, petrol and other prices in Australia will rise due to the global impact of the Israel–Iranian war.
