Oil Prices Spike as U.S.-Iran Military Strikes Resume, Driving Brent and WTI to Multi-Month Highs

The Quick Take

• Brent crude and WTI oil prices surged sharply after the U.S. and Iran resumed military strikes against each other
• The resumption of hostilities ended a month-long hiatus and reignited fears over Strait of Hormuz disruption
• Energy markets are pricing elevated geopolitical risk premium as the conflict escalation threatens global supply routes

The resumption of U.S.-Iran military strikes — after a month-long pause — sent crude oil prices sharply higher across both Brent and WTI benchmarks, as energy markets priced an elevated geopolitical risk premium into near-term supply expectations. The Strait of Hormuz, through which approximately 20% of global seaborne oil trade transits, is the critical chokepoint whose operational status drives the magnitude of the oil market response to U.S.-Iran conflict escalation. Any credible threat to Strait traffic translates directly into supply disruption fears that push crude prices higher regardless of actual flow changes, as traders hedge through futures markets preemptively.

The oil price spike carries significant second-order market implications beyond the energy sector. Higher crude prices re-ignite inflation concerns in economies already sensitive to energy input costs — the U.S. Federal Reserve, which had been signalling a patient stance on rate policy, faces renewed pressure if oil-driven inflation translates into sticky CPI readings. Gold prices fell concurrently (a pattern seen in prior U.S.-Iran escalation cycles) as the rate-hike probability repriced upward. Equity markets, particularly consumer discretionary and airlines, face margin headwinds from elevated jet fuel and energy costs.

The forward signal is whether the Strait of Hormuz remains operationally open — any confirmed disruption to tanker traffic would push Brent above $100/barrel rapidly. Key geopolitical triggers include Iranian government statements on Strait closure intentions and U.S. Navy escort operations for commercial tankers. The macro variable is the OPEC+ spare capacity buffer: Saudi Arabia and UAE hold approximately 3-4 million barrels per day of spare capacity that could partially offset a Hormuz disruption, but releasing it under active conflict conditions carries its own political risks.
