The deal’s implementation now has four working groups, Sanctions Termination, Nuclear Affairs, Reconstruction, and Monitoring, plus two coordination mechanisms for Lebanon and Hormuz demining. Reading the architecture reveals the gap: there is no working group for strait governance. The waterway the crisis was about got a demining mechanism and nothing else. The basket post asked to decouple the strait; instead it was dropped. This post argues for the fifth working group, the one the strait actually needs.

The crisis taught the world’s shipping to go dark. By May, more than two-thirds of non-Iranian transits through Hormuz were switching off AIS, carrying legitimate UAE, Qatari, Kuwaiti, and Iraqi oil through Gulf-of-Oman transfers with transponders off. The dark-fleet tactic, pioneered for sanctions evasion, became a commercial norm for allied oil, and the transparency the market depends on broke in a way that cannot be unseen. A governed strait makes identified transit a condition of passage. This post reads the opacity the vacuum normalized.

The deal now runs on two 60-day clocks. The first is the strait’s no-toll window. The second started this week: Treasury issued a temporary 60-day general license authorizing Iranian oil sales, freeing ~67M stranded barrels. It is the buyer-leg counterpart to the no-toll window, and it has the same shape: relieve the emergency now, defer the institution. A general license is a revocable waiver carved out of a standing prohibition, not the permanent settlement durable commerce requires. This post reads the second clock.

Iran and the US are circulating different versions of the deal: one draft releases $25bn in frozen Iranian assets, the other contains no such provision; Iran briefs near-simultaneous relief, the US briefs sequenced rewards. The strait clause is consistent, but the pattern isn’t: a deal whose text the parties dispute is the document-level twin of a strait whose status they dispute. No authoritative reference, at any level. This post reads the parallel.

On 27 May 2026, OFAC added the Persian Gulf Strait Authority to the SDN list, framing it as an IRGC instrument and warning shippers, insurers, financiers, and charterers of sanctions exposure regardless of payment method. Designating the collector itself is the institutional crux — and it collides directly with a reopening deal that would route global shipping through that very body. This post reads the collision and what an acceptable collector looks like.
