Crude prices climbed back above prewar benchmarks after attacks on three commercial vessels in a critical Middle East strait disrupted one of the world's most vital oil transit routes. The assaults, concentrated over a single week, forced tankers to alter course or delay passage, tightening immediate supply availability and injecting a fresh geopolitical risk premium into the market.

Brent crude, the international benchmark, rose above $85 a barrel as traders priced in the possibility of sustained interference with the roughly 20 million barrels per day that typically flow through the chokepoint. Shipping insurers have already raised war-risk premiums, adding direct costs to every cargo and effectively functioning as a tax on global energy trade.

The price response underscores how fragile the current supply-demand balance remains. OPEC+ spare capacity sits at multi-year lows, strategic petroleum reserves are depleted, and non-OPEC growth has failed to meet earlier forecasts. Any prolonged disruption cannot be easily offset, leaving markets vulnerable to further escalation.

For investors, the episode reinforces that energy inflation remains a live risk despite recent demand concerns. Equity exposure to tanker operators and insurers faces near-term volatility, while central banks monitoring headline inflation data must now account for a potential energy-driven upside surprise in coming months.
