The United States has officially enforced a naval blockade against Iranian ports and the country's coastline, a move that took effect Tuesday evening.

The Joint Maritime Information Center, which is led by the US Navy, confirmed the implementation of the restrictions, marking a significant escalation in maritime tensions in the region.

The price jump follows a period of heightened volatility, with Brent having climbed above $75 a barrel on Monday after initial reports of the reimposed naval blockade circulated.

Brent crude futures surged past $82 a barrel in response to the news, reflecting immediate market anxiety over potential disruptions to global energy supplies.

The latest enforcement action removes any ambiguity about the operational status of the blockade, prompting traders to price in a higher risk premium for shipping through the Strait of Hormuz.

The blockade represents a sharp reversal in diplomatic and military posture, coming shortly after the US Treasury Department revoked the general license that had permitted the sale of Iranian crude oil.
