The United States has revoked the general license that previously authorized the sale of Iranian crude oil, a decisive policy shift that removes a key outlet for Tehran's exports.

The move, reported by multiple wire services, signals a hardening of Washington's stance on Iranian energy revenues amid ongoing geopolitical friction in the region.

This development tightens the constraints on Iranian oil flows, which have long been a wildcard in global supply calculations.

By eliminating the general license, the U.S. effectively narrows the legal pathways for international buyers to engage with Iranian crude, potentially forcing Tehran to rely more heavily on informal or sanctioned channels.

For traders, this adds a layer of uncertainty to Persian Gulf supply dynamics, particularly as markets remain sensitive to any disruption in the region.

The revocation comes against a backdrop of heightened tensions in the Persian Gulf, where shipping security and export routes have been under scrutiny.
