Brent crude briefly climbed above $91 per barrel as escalating US-Iran tensions rattled energy markets and heightened concerns about supply risks. The move reflects a sharp geopolitical jolt for oil traders, who are now focused on the potential fallout from conflict near one of the world’s most important shipping routes.

At the center of the market reaction is the Strait of Hormuz, a critical energy chokepoint for global crude flows. Any threat to shipping through the passage can quickly lift prices, and the latest military escalation has renewed fears that disruptions there could tighten supply and increase volatility across oil markets.

The price jump is also feeding through to consumers in the United States, where gasoline prices have moved above $4. Higher fuel costs add pressure to household budgets and can revive wider inflation worries, especially when crude is already trending higher.

For now, traders appear to be pricing in the risk that the conflict could deepen or affect transport through the region. With oil markets absorbing one of their biggest geopolitical shocks in years, Brent’s move above $91 underscores how quickly tensions in the Middle East can ripple through global energy prices.
