Iran has blocked tanker traffic through the Strait of Hormuz since late February, when the U.S. and Israel began military operations, causing disruptions to global oil supply and pushing prices higher. Separately, Iran claimed it struck a U.S. warship in the strait, a claim the U.S. military has denied.

Why the Strait of Hormuz Matters

The Strait of Hormuz is the world's most important oil chokepoint. Roughly 20% of global oil supply and a significant share of liquefied natural gas passes through this narrow waterway between Iran and Oman. Any sustained blockade directly tightens global energy supply, with immediate effects on crude oil prices and shipping costs.

Iran's move to block tanker traffic since late February has already created supply and price shocks, according to the source. The longer the closure holds, the more pressure builds on oil-importing economies, including India, which relies heavily on Gulf energy flows.

Conflicting Claims Add Military Tension

Iran's assertion that it struck a U.S. warship in the strait marks a significant escalation in rhetoric, even if the U.S. military flatly denies it. In active conflict zones, disputed claims like this can move energy markets quickly, as traders price in the risk of a broader confrontation that could further restrict passage through the strait.

The U.S. denial means the full picture remains unclear. What is established is that the strait is already disrupted, and any confirmed military exchange there would almost certainly intensify the supply shock already underway.

For India, the stakes are direct. India imports a large share of its crude oil from the Persian Gulf, and Hormuz is the exit route for most of that supply. A prolonged closure or military escalation raises the cost of every barrel that has to be rerouted around Africa or sourced from further afield.

Watch for: any independent confirmation of the warship incident, changes in oil futures pricing, and whether major tanker operators reroute vessels away from the strait in coming days.
