How could US-Iran conflict and attacks affect Brent crude oil prices?

This instability makes critical maritime chokepoints, like the Strait of Hormuz, highly sensitive to conflict. When tensions escalate or attacks occur near the Strait of Hormuz, the resulting disruption to oil flows and market sentiment directly influences the price and volatility of Brent crude oil.

Why it matters
Brent crude oil is a global benchmark, and its price movements are critical indicators of global economic health and supply chain stability. Because the Strait of Hormuz is a vital maritime chokepoint for global energy transport, any disruption or heightened risk in that region can immediately impact the cost of energy worldwide.
This dynamic is not unique to the Middle East. Historically, geopolitical tensions have been a primary driver of commodity price volatility, forcing markets to price in the risk of supply interruption. The reports show that while tensions push prices up, diplomatic efforts can quickly reverse that trend, making the political situation as important as the physical supply.
