US Sanctions Iran, IRGC-Linked Entities Over Hormuz Attacks
The U.S. Treasury has imposed a fresh sanctions package targeting Iran and IRGC-linked entities in response to recent attacks in the Strait of Hormuz.

The United States has imposed a new round of sanctions on Iran and entities linked to the Islamic Revolutionary Guard Corps in response to recent attacks in the Strait of Hormuz, according to reporting from the Jerusalem Post. The designations were issued by the U.S. Treasury and require any U.S.-based involvement with the sanctioned companies to be reported to the Office of Foreign Assets Control (OFAC).
What we know
The action targets Iran and a set of entities described as IRGC-linked, following the tanker and shipping attacks in and around the Strait of Hormuz that have rattled global oil markets over the past week. The measures direct any U.S. person with a nexus to the newly designated parties to disclose that involvement to OFAC, the Treasury office that administers economic sanctions.
The move builds on the Treasury’s July 7 revocation of Iran’s oil export license, which was itself a direct response to the Hormuz tanker strikes. That earlier action pulled General License X and replaced it with a 10-day wind-down provision.
What we don’t know
At the time of publication, the full list of designated entities, the specific IRGC sub-units named, and the precise secondary-sanctions exposure for foreign firms have not been independently confirmed. Treasury has not yet published an accompanying press release visible on OFAC’s public feed, and the story is developing.
Context
Sanctions are the U.S. lever of choice while the ceasefire memorandum brokered in June continues to fray. Washington has publicly demanded that Tehran commit to halting attacks on shipping in the strait, and the OFAC track is running in parallel with the ongoing U.S. strike campaign that CENTCOM says has now hit roughly 90 targets across Iran.
For markets, the practical question is how aggressively OFAC enforces against the Chinese “teapot” refiners that have been the main buyers of sanctioned Iranian barrels. Enforcement posture — not the paper designations — is what determines whether Brent reprices again.
What to watch
- OFAC’s official Specially Designated Nationals (SDN) list update and any accompanying general licenses or FAQs.
- Whether the package names Chinese, Emirati, or Hong Kong front companies — the tell for secondary-sanctions enforcement.
- Brent and WTI open on Sunday evening and any Iranian regime response, including further Hormuz activity.
