- New network, same oil. The October 21 designations added five individuals, four entities and nine vessels to the Treasury’s Iran sanctions list, targeting what officials describe as the legal and maritime infrastructure that enables Iranian crude to reach customers without triggering existing restrictions.
- Panama and Singapore links. The sanctioned parties include a Panama- and Greece-based law firm, Karnakis and Karnakis, and two shipping companies registered in Singapore and the UAE, expanding US enforcement geography beyond the Middle East.
- Iran’s counter-condition. Iran’s President Masoud Pezeshkian has reiterated that sanctions relief must precede any nuclear or diplomatic talks — a condition Washington has not accepted — making the latest round an additional obstacle to negotiations that have stalled since February’s ceasefire.
The US Treasury’s Office of Foreign Assets Control announced the designations on October 21, acting under Executive Order 13902, which targets Iran’s energy, petrochemical and metals sectors. Steptoe’s sanctions tracker identified the named parties as Karnakis and Karnakis, a law firm with offices in Panama and Greece; Roxette Maritime Shipping and Trading S.A., along with seven of its cargo vessels; Amigoz Singapore Pte. Ltd.; and Whales Shipping Line LLC, a UAE-registered company controlling two additional vessels. Five individuals connected to these entities were also designated.
What the Designations Cover
Operation Economic Outcast is the label Treasury has used since mid-2026 for enforcement rounds that target the commercial intermediaries in Iran’s petroleum supply chain — not refiners or terminal operators, but the law firms, ship managers and financial agents who arrange chartering, paperwork and payment transfers. The October 21 round focuses on companies that, according to OFAC, have provided services that helped Iran move crude and petroleum products despite the existing US sanctions regime.
General Licenses GG and HH, also issued on October 21, authorise counterparties to wind down existing dealings with the newly designated entities through November 20, 2026. This follows an earlier and larger action that targeted 22 vessels and 27 entities — which Treasury called its biggest Iran shadow fleet strike at that point — and together the rounds form a sustained campaign against the service layer of Iran’s oil exports.
Iran’s Position and Diplomatic Deadlock
President Pezeshkian confirmed in recent remarks that Tehran will not enter substantive nuclear or broader diplomatic talks while the current sanctions architecture is intact. That position puts the two sides in a formal impasse: Washington conditions any sanctions relief on verifiable cuts to Iran’s uranium enrichment program, while Tehran insists relief must come first. Neither side has moved toward the other’s position since the ceasefire that ended the February conflict.
Iran’s petroleum exports have continued at roughly 1.7 million barrels per day, according to third-party tracking estimates, primarily to buyers in Asia who are either outside the dollar system or willing to absorb the legal risk of dealing through the shadow fleet. The October 21 action targets the legal and corporate structures that make those transactions harder to trace and stop.
Transatlantic Sanctions Picture
European and US approaches to Iran sanctions have remained relatively coordinated. On Russia, the picture is more fractured: the EU confirmed this week that its 22nd Russia sanctions package is in preparation, while Washington has authorised Russian diesel imports until April 2027 — a carve-out European capitals have criticised as undermining the joint Western stance on Russian energy. On Iran’s petroleum trade, enforcement continues on both sides of the Atlantic.
