The US Treasury extended GL-134B, the OFAC General License authorising Russian seaborne-oil transactions, to 16 May 2026 on the same calendar day Iran's GL-U was allowed to lapse 1. Treasury Secretary Scott Bessent oversees both files; either renewal could have been declined or signed at his discretion. Treasury's choice to sign one and not the other on a single Saturday produced a policy act rather than a scheduling artefact.
Russia's side of the ledger had a readable expiry. GL-134A expired on 11 April and an extension had been widely expected since ; Treasury's silence between 14 April and 19 April made the asymmetry predictable rather than surprising . When Treasury did break silence, it broke it only for Russia. GL-134B now covers Russian seaborne-oil transactions through 16 May; GL-U covers no Iranian tanker past midnight Washington time.
For crude buyers, Saturday's paperwork produces a legally two-tier oil market. An Indian state refiner loading Russian crude this week retains signed cover under GL-134B; the same refiner loading Iranian crude loses it under the GL-U lapse and picks up secondary-sanctions exposure. The instruments governing the two flows are no longer symmetrical, and the asymmetry is now on paper that compliance teams, banks and foreign ministries can read without interpretation.
