General License 134C (GL 134C), the US Treasury waiver that lets buyers take Russian-origin crude loaded before 12 March, expires at 12:01am Eastern Daylight Time on Wednesday 17 June, with no GL 134D announced 1. A general licence is a standing carve-out from sanctions; this one is the legal shield that has kept Russian seaborne oil moving through Western-touched insurance and shipping channels. Treasury has stayed silent on renewal.
This is the third consecutive 30-day bridge. The previous waiver, GL 134B, lapsed in mid-May , and the Cuba-excluded GL 134C that followed was issued on 18 May . Both earlier cliffs closed at the last minute without ending the trade, which is why the market is not yet pricing a clean break.
Let GL 134C lapse, and the consequence is structural rather than symbolic. Shadow-fleet operators who currently point to the waiver when arranging insurance would have to self-insure against secondary US sanctions on every cargo. The timing compounds the pressure: the legal cover drains away in the same week the Strait of Hormuz, due to reopen under the new US-Iran ceasefire, removes the scarcity premium that had lifted Russian crude prices through the spring. The price leg and the legal leg would tighten together, the combination Western sanctions architects have wanted since 2022.
