OFAC designated the two bodies selling IRGC-approved transit cover in the Strait of Hormuz, payable in Bitcoin, alongside four shadow-fleet tankers and a front that crowdsourced targeting tips.

Key takeaway

Tehran collects a Hormuz toll through insurance paperwork, with no gunboat and no signed agreement.

The Office of Foreign Assets Control (OFAC), the US Treasury unit that administers American sanctions, designated Persian Gulf Marine Insurance Company and HormuzSafe Marine Services Authority on Wednesday 29 July under Executive Order 13902 ¹. The scheme those two bodies run makes cover compulsory: a vessel transiting the Strait of Hormuz must buy IRGC-approved insurance against risks Iran itself creates. HormuzSafe accepts Bitcoin and other digital assets, and the sanctioned financier Babak Zanjani promoted it on social media.

HormuzSafe collects without putting a boarding party on a single deck. No port accepts an uninsured hull and no charterer books one; cargo owners, classification societies and flag states all demand valid cover before a ship moves. Forcing transits to buy Iranian-approved paper therefore extracts payment through the commercial liability chain, at the point where a refusal costs the shipowner the voyage rather than the ship. Washington's answer to a Hormuz toll has been that nobody may charge for passage at all, and this scheme collects without ever putting the question to a negotiator .

OFAC named eight shadow-fleet tankers in the same action, hulls that disguise Iranian crude through flag-of-convenience registration, opaque ownership and ship-to-ship transfers, among them WELL SAIL, LILY, AL SALMI and BREEZE V. That takes Treasury past 100 vessels designated this year ². A separate release the following day, under Executive Order 13224, named six targets across China, India, Russia and Iran ³.

DadeNegar Startup Studio neither moves cargo nor sells tickets. The IRGC-affiliated front ran a public website soliciting crowdsourced locations of American and Israeli equipment and relayed strike requests to the Guard ⁴. Iran has used front companies to procure components for decades, and the Zanjani network drew its own designation on 24 July . Buying targeting information from passers-by is a different function from buying centrifuge parts, and it places anyone who photographed a convoy inside the kill chain.

Deep Analysis

In plain English

The US Treasury's sanctions arm, OFAC, added two Iranian shipping insurance companies and eight tankers to its blacklist on 29 July, and an Iranian tech investment firm called DadeNegar Startup Studio the following day. This is part of a long-running effort to stop Iran from selling oil by cutting off the insurance and financial services that let its ships keep operating despite sanctions. The tankers and companies named will struggle to get insurance, dock at most ports, or use the international banking system.

What could happen next?

Consequence
The four newly sanctioned tankers will likely re-flag and seek alternative insurance within weeks, following the pattern of prior 2026 designation rounds.
Meaning
Naming the insurance company directly, rather than only the tankers, targets the mechanism that has let sanctioned vessels keep operating.

Primary parallel: The 2019 OFAC designation of the National Iranian Tanker Company established the template of sanctioning the insurance and shipping-management layer around Iranian oil exports rather than individual vessels, forcing repeated re-flagging cycles that this action against HormuzSafe now extends to the insurance underwriters themselves.

Counter-parallel: Unlike 2019, when NITC's designation measurably reduced Iranian tanker insurability for over a year, the pace of shadow-fleet reconstitution has accelerated through 2026's repeated OFAC rounds (ID:3971, ID:3310), suggesting the substitution network has grown more resilient with practice.

The dual-authority structure, Executive Order 13902 against the insurers and tankers, Executive Order 13224 against DadeNegar Startup Studio, reflects Treasury targeting two distinct financial functions: 13902 covers Iranian petroleum-sector facilitation, while 13224 covers terrorism-financing conduits, meaning DadeNegar is being treated as a financing vehicle rather than a petroleum-trade entity.

Each of the four newly designated shadow-fleet tankers now faces the same re-flagging cost structure prior rounds imposed: loss of P&I cover typically forces a vessel through a chain of shell-company ownership changes lasting four to eight weeks before it can resume port calls under a new flag.

Consensus view: RUSI's Sidharth Kaushal reads the OFAC pairing of Persian Gulf Marine Insurance Company and HormuzSafe under Executive Order 13902 as targeting the underwriting layer specifically, since shadow-fleet tankers cannot obtain port access or P&I cover in most jurisdictions without a domestic Iranian substitute insurer standing behind the hull.

Counter-view: Tehran's Institute for International Energy Studies argues the designation changes little in practice, pointing to the precedent of the April 2026 OFAC round after which sanctioned tankers simply re-flagged and re-insured through parallel Iranian entities within weeks.

Key tension: Whether targeting the insurance intermediaries themselves, rather than only the tankers, closes the substitution loophole that let prior sanctions rounds be absorbed so quickly.

Treasury names a Hormuz insurance racket

Tehran has found a way to collect a Hormuz toll through commercial liability rather than gunboats, and it works whether or not any diplomatic version of the same demand ever succeeds.

Treasury goes quiet on Iran for days

OFAC's 29 July designation of HormuzSafe and Persian Gulf Marine Insurance was its last Iran-related action before a four-day gap opened in the sanctions tempo.

Different Perspectives

Shipping and insurance industry

UKMTO counted about 20 US-facilitated Hormuz transits a day to 11 September against only 6 visible on AIS, with traffic still around 90% below the 138-a-day pre-war baseline. War-risk underwriters cannot price hulls they cannot see, or resolve whether the tanker El Gaia hit a mine, as Iran claims, or a missile and drone, as CENTCOM says.

European refiners

European refiners, including Poland's Orlen, absorbed a roughly $26 gap between Dated Brent at $130.80 on 15 September and ICE Brent futures settling at $103.87 on 18 September, a spread that widened from $13.45 on 9 September rather than newly opening. Their futures hedges no longer cover what they now pay for physical barrels.

Saudi Arabia

Saudi Aramco zeroed European term customers' October allocations and rerouted roughly 60 million barrels to Asia through Ras Tanura and Sohar, using Red Sea and Gulf terminal capacity built years ago to cut Hormuz exposure. Riyadh reallocated existing supply rather than negotiating a shortfall with Europe.

Qatar

Qatar's energy minister Saad al-Kaabi told Bloomberg at the Qatar Economic Forum on 20 September that Bessent's two-year Hormuz-obsolescence forecast is wrong, and that Doha has deliberately built no bypass pipeline. Qatar's gas exports run through one waterway by choice, not oversight.

Iran (foreign ministry and Majlis)

Iran's foreign ministry and 130 Majlis deputies moved toward NPT withdrawal this week, with lawmaker Hossein-Ali Haji Deligani filing a triple-urgency bill on 20 September that Speaker Qalibaf has not yet scheduled. Tehran treats treaty membership as leverage still on the table, not yet spent.

Russia and China

Moscow and Beijing vetoed the Panel of Experts' renewal, maintaining Resolution 2231 lapsed in October 2025 and the 2025 snapback was never validly triggered, so the sanctions architecture the Panel enforces has no current legal standing. Both governments frame the veto as upholding law, not shielding Tehran.
