US Imposes Fresh Iran Oil Sanctions Despite Progress on Ceasefire Talks

The United States has announced a new round of sanctions targeting Iran’s military-linked oil trade, even as Washington and Tehran move closer to extending a ceasefire agreement and restoring shipping access through the strategically important Strait of Hormuz.

According to the U.S. Treasury Department, sanctions were imposed on eight vessels allegedly involved in transporting Iranian crude oil and petroleum products to international markets. Among the targeted ships are the Marshall Islands-flagged tanker Flora, the Comoros-flagged crude carrier Hauncayo, and the Panama-flagged tanker Ill Gap.

U.S. Treasury Secretary Scott Bessent said the measures are designed to prevent Iran from increasing oil revenues that could be used to rebuild its military capabilities. The sanctions form part of Washington’s broader effort to pressure Tehran while maintaining restrictions on entities connected to Iran’s armed forces.

The latest action comes amid ongoing diplomatic discussions between the United States and Iran regarding a ceasefire following the conflict that began on February 28. Although negotiators have reportedly reached a tentative understanding, President Donald Trump has not yet formally approved the proposed ceasefire arrangement.

The conflict has significantly disrupted global energy markets by affecting operations in the Strait of Hormuz, one of the world’s most critical maritime trade routes. Roughly 20% of global oil and natural gas shipments typically pass through the narrow waterway connecting the Persian Gulf to international markets. Any disruption to shipping activity in the region has immediate implications for global energy prices and supply chains.

In addition to the vessel sanctions, the Treasury Department designated more than 15 companies and organizations allegedly involved in facilitating Iranian oil exports. These include Hong Kong-based Worth Seen Energy Limited, Dubai-based Symphony Shipping and Maritime Management Inc., and Hong Kong-based Mehdiyev Trading Co.

U.S. officials stated that several sanctioned entities support the oil sales network linked to Iran’s armed forces. Treasury authorities specifically accused Worth Seen Energy Limited of procuring refined petroleum products for the National Iranian Oil Company on behalf of Sepehr Energy Jahan, an organization previously sanctioned by the United States and identified as the oil sales arm of Iran’s Armed Forces General Staff.

The new sanctions highlight Washington’s continued pressure campaign against Iran’s energy sector, even as diplomatic efforts seek to stabilize the region and reopen critical global shipping routes.
