The United States has announced a new round of sanctions targeting Iran’s crude oil sector, intensifying economic pressure on Tehran. The move, confirmed by the U.S. Treasury Department, focuses on disrupting networks allegedly involved in facilitating Iran’s oil trade.

According to officials, the sanctions specifically target individuals and entities linked to the Shamkhani network, a group associated with Iranian businessman Mohammad Hossein Shamkhani. Authorities claim the network has been actively involved in bypassing existing restrictions through complex financial and shipping operations.

U.S. Treasury Secretary Scott Bessent stated that those sanctioned have benefited financially while contributing to economic hardship within Iran. He emphasized that the measures aim to curb illicit activities tied to the country’s oil exports.

The Treasury Department further noted that the Shamkhani network operates across multiple regions, including Iran and the United Arab Emirates, using front companies, consultancies, and shipping firms to evade sanctions.

In addition to the network, sanctions have also been imposed on Seyyed Badruddin Mousavi, accused of providing financial support to the Iran-backed militant group Hezbollah. Three additional companies have been targeted for their alleged role in laundering funds generated from Iranian crude oil sales.

The latest measures highlight Washington’s continued efforts to tighten restrictions on Tehran, particularly around the strategically vital Strait of Hormuz, a key global oil transit route. Officials say these actions are part of a broader strategy to limit Iran’s economic capabilities and curb its regional influence.
