The United States Treasury Department has imposed new sanctions on eight Iranian oil tankers and 10 affiliated entities, seeking to intensify pressure on Iran’s energy sector. Information on the latest measures was published on the Office of Foreign Assets Control website, according to a report published on July 29, 2026.

The US administration said the action is part of its “maximum pressure” policy aimed at cutting revenue flows from Iran’s oil trade and its covert fleet. Washington alleges that Tehran has used proceeds from oil sales to produce weapons and finance regional allies or proxy groups.

The announcement comes amid heightened tensions in the Middle East, where reciprocal military strikes between the United States and Iran are continuing, the report said. Conflict has effectively blocked the Strait of Hormuz, disrupting international shipping routes and severely affecting oil and energy supplies to global markets.
