Iran's Islamic Revolutionary Guard Corps (IRGC) has issued a fresh threat against the United States, vowing to inflict "greater humiliation" in response to what it described as American interference in the Strait of Hormuz.

The statement arrives as the military wing maintains its declaration that the waterway remains closed to unauthorized maritime traffic, a move that has already disrupted global energy flows and triggered a surge in shipping insurance costs.

The hardline rhetoric reinforces the operational reality on the water: the Strait of Hormuz, which handles roughly a fifth of the world's oil consumption, is effectively under Iranian control.

Since the IRGC Navy declared the closure earlier this week, international tankers have been forced to reroute or halt operations, creating immediate bottlenecks for crude exports from the Gulf region.

The new verbal escalation suggests that diplomatic off-ramps are currently nonexistent, with Tehran signaling that military posturing will continue until its demands are met.

Markets have already begun pricing in the supply disruption.
