Iran has begun to formalize a demand for transit tolls in the Strait of Hormuz, a critical artery for global oil trade, during a two-week ceasefire with the United States.
This new policy requires tankers to pay for passage in non-USD currencies, specifically the Chinese yuan and, in some cases, cryptocurrency. This isn't just a theoretical demand; reports confirm that a de facto 'toll-booth' system was already in place, with at least two vessels having paid in yuan for escorted passage through an Iranian-controlled corridor. The ceasefire provides a political opening for Tehran to transition this ad-hoc system into a more formalized revenue stream.
This development is the culmination of several escalating factors. First, the conflict that began in late February led to a near-shutdown of the strait, drastically reducing vessel traffic and highlighting Iran's strategic leverage. Second, in response to the heightened risk, maritime war-risk insurance premiums skyrocketed, surging to 3-5% of a vessel's hull value. For a large tanker, this translates to a $3-5 million cost per voyage, making a reported Iranian toll of around $2 million seem economically attractive by comparison. Third, Iranian lawmakers had already been laying the domestic legal groundwork for such fees, framing them as payments for 'security services.'
Iran's demand directly challenges long-standing international norms, particularly the UN Convention on the Law of the Sea (UNCLOS), which prohibits charging fees solely for passage. While Iran argues the fees are for services rendered, this interpretation is contested. Furthermore, the insistence on yuan and crypto payments is a clear move toward de-dollarization, leveraging financial channels that bypass the U.S. financial system and complicate sanctions enforcement.
This situation creates a significant compliance dilemma for shippers and insurers. A temporary U.S. sanctions waiver, General License U, allows for transactions 'ordinarily incident and necessary' for oil deliveries, but it's highly ambiguous whether a toll paid to an entity linked to Iran's IRGC would qualify. The license's expiration on April 19 adds another layer of urgency and uncertainty to this complex geopolitical and economic puzzle.
