How could the US-Israeli war on Iran affect Brent crude oil prices?
War on Iran may increase supply risk and volatility for Brent The ongoing U.S.-Israeli conflict with Iran is increasing regional volatility and straining security arrangements in the Middle East. This instability has allowed Iran to gain leverage by effectively closing the Strait of Hormuz, a critical trade route for oil and gas. Disruptions to this vital energy infrastructure and the resulting global supply risk are rattling the global economy, which directly influences the price and volatility of Brent crude oil.

Why it matters
Brent crude is a global benchmark for oil prices, and its volatility is highly sensitive to geopolitical risks in major oil-producing regions. The Middle East, particularly the Gulf States, is central to global energy supply, making any disruption to its trade routes a major factor for international markets.
The conflict has already demonstrated that regional powers are seeking to diversify security partnerships, as Gulf states question the reliability of traditional American security arrangements. This shift in regional power dynamics, combined with Iran's strategic leverage over the Strait of Hormuz, creates significant uncertainty for global energy markets.
