The United States has launched military strikes against Iranian coastal defense systems on the island of Greater Tunb, marking a significant escalation in tensions at the entrance to the Strait of Hormuz.

US Central Command confirmed the air attacks on Wednesday, targeting strategic military infrastructure in one of the world's most critical maritime chokepoints.

The operation places direct pressure on global shipping routes, as Greater Tunb sits at a key juncture for oil and gas transit.

Markets are likely to react to the heightened risk of disruption, with potential implications for freight rates, tanker insurance premiums, and energy commodity prices.

The strikes follow a 90-minute airstrike campaign that targeted Iranian military defenses, signaling a shift from diplomatic posturing to direct kinetic engagement in the region.

This development intensifies existing concerns about the security of energy flows through the Strait of Hormuz, which handles a substantial portion of global oil trade.
