U.S. Sanctions 8 Vessels and 15 Entities in Iran Military Oil Trade

Eight vessels and more than 15 companies were newly sanctioned by the U.S. Treasury for moving Iranian crude and petroleum products tied to Tehran's military oil network.
Treasury said the measures aim to block Iran from boosting oil revenue to rebuild its armed forces, naming firms in Hong Kong and Dubai and tankers flagged in the Marshall Islands, Comoros and Panama.
Worth Seen Energy was cited for procuring refined products for the National Iranian Oil Company on behalf of Sepehr Energy Jahan, the oil sales arm of Iran's Armed Forces General Staff.
The move came even as Washington and Tehran reached a tentative agreement to extend a ceasefire and reopen shipping through the Strait of Hormuz, which normally carries about 20% of global oil and gas flows.
Trump has not yet approved the ceasefire tied to the war launched by the U.S. and Israel on Feb. 28, leaving sanctions pressure in place as markets watch the strait.
Amidst a fragile ceasefire, why is the US sanctioning Iran while negotiating to reopen the Strait of Hormuz?
Will the escalating dispute over tolls in the Strait of Hormuz shatter the tentative US-Iran peace agreement?
U.S. Sanctions on Iran’s Oil Trade in 2026: Impact, Evasion Networks, and the Geopolitical Battle for the Strait of Hormuz
Overview
On May 27, 2026, the United States imposed new sanctions on Iran by adding the Persian Gulf Strait Authority to its list of sanctioned entities, citing threats to U.S. national security. This move followed Iran’s closure of the Strait of Hormuz after a war began between the U.S., Israel, and Iran. The Persian Gulf Strait Authority, which manages passage through this vital waterway, is now at the center of concerns about international maritime security. These actions highlight escalating tensions and the strategic importance of the Strait, as the U.S. seeks to counter Iran’s influence and protect global energy flows.
