US Treasury Targets Iran’s Bitcoin “Insurance” Scheme for Hormuz Transit, Sanctions Two Firms

Washington is moving to shut down Tehran’s attempt to graft crypto rails onto a coercive toll at the world’s key oil chokepoint. On July 29, the U.S. Treasury’s Office of Foreign Assets Control sanctioned two Iranian firms that force commercial ships to buy IRGC-approved maritime “insurance” to cross the Strait of Hormuz, a corridor that carries roughly one-fifth of global oil flows.

How the mechanism works - Vessels transiting Hormuz are required to purchase coverage that, according to Treasury, protects against risks Iran itself manufactures—chiefly seizure. - Policies are brokered by the Persian Gulf Marine Insurance Company, created by Iran’s insurance regulator. - The cover is approved by the IRGC-backed Persian Gulf Strait Authority, which Washington designated in May.

The crypto rail The second sanctioned entity, HormuzSafe Marine Services Authority (often branded “HormuzSafe”), was developed by Iran’s Ministry of Economy. It markets traffic control, security, emergency response, and insurance—and accepts Bitcoin and other digital assets. OFAC said that crypto acceptance is meant to sidestep Western sanctions. Iranian financier Babak Morteza Zanjani, sanctioned earlier this year, promoted HormuzSafe on social media.

Analysts were skeptical this spring when reports suggested Iran would levy crypto transit fees starting at $1 per barrel. In April, TRM Labs policy lead Ari Redbord said he saw no evidence of crypto being used at scale for Hormuz tolls, and observers noted the spokesperson cited then was a union official, not a government decision-maker. Treasury’s designation resolves at least one ambiguity by naming a ministry-built firm that explicitly takes Bitcoin.

Shadow fleet squeeze Treasury Secretary Scott Bessent said the regime is “desperate for cash,” its economy “in freefall” with triple‑digit inflation, and vowed the U.S. would not let Iran “hold global commerce hostage.” The same action targeted eight tankers and their operators over Iranian crude and petroleum cargoes, with most of those companies registered in Hong Kong. Since January, more than 100 vessels linked to Iran’s shadow fleet have been sanctioned. Treasury said the insurance scheme was designed to replace revenue lost to Operation Epic Fury.

What actually matters here: Bitcoin as a coercion conduit Iran is testing whether open blockchain payments can operationalize state-backed shakedowns at scale. That bet has trade‑offs: - Technological: On-chain flows are traceable. Sustained use would inevitably touch identifiable services or liquidity venues, inviting rapid blacklisting. If actors pivot to obfuscation, they raise cost and friction—and still leave metadata crumbs. This rarely scales cleanly. - Business calculus: Shippers juggle seizure risk versus sanctions exposure. A “mandatory insurance” paywall offers a deterministic path through Hormuz, but it also tags payers for potential secondary sanctions. Many risk officers will prefer lawful reroutes or insured alternatives over a wallet address posted by an IRGC‑aligned authority. - Signaling and compliance: A government‑linked platform that accepts Bitcoin forces exchanges, OTC desks, and service providers to harden controls around any counterparties associated with HormuzSafe. Expect fresh OFAC identifiers and broader screening rules, even without definitive volume on-chain. - Ethics and perception: Dressing extortion as insurance doesn’t alter what it is. Using Bitcoin for it doesn’t indict the tech, but it does raise reputational stakes and accelerates policy convergence between crypto compliance and maritime sanctions enforcement.

Two near-term indicators to watch: verifiable on‑chain receipts tied to entities named by OFAC, and whether shipping payments migrate to private arrangements off public ledgers. For now, market participants still see uncertainty—on Myriad, a prediction market, users assign a 38% probability the Iranian blockade ends by August 31. If that eases, the incentive to lean on a crypto toll weakens; if it persists, enforcement and analytics will dictate whether this experiment gains any real throughput.
