The US Treasury's Office of Foreign Assets Control (OFAC), the bureau that runs American sanctions, let General License 134C lapse on 17 June with no successor issued as of 1 July 1. The licence is the waiver that lets buyers take Russian crude loaded before a cut-off date, and its expiry has now stretched into a 15-day gap.
Every earlier lapse was bridged within one or two days; this is the longest of the war 2. A permanent lapse would strip the legal cover under which some buyers still take Russian crude, tightening the channel further. Whether OFAC issues a General License 134D or lets the waiver die will decide how much Russian oil can move without sanctions risk.
Washington's mediation has been dormant since Secretary of State Marco Rubio declared it stagnant on 22 May, and Vladimir Putin's published calendar shows no US or Ukrainian diplomatic contact in the week 3. The unrenewed waiver sits inside that same absence, one of the few levers Washington still holds over Russian oil revenue, currently left idle.
