The Treasury Department's Office of Foreign Assets Control posted General License 134B on April 17, authorizing the orderly offload of Russia-origin crude oil and petroleum products already loaded on vessels as of that date through 12:01 a.m. EDT May 16. [1] The May 3 brief, Treasury General License 134B confirming May 16 expiry with April 17 loaded-on-or-before, recorded the issuance and the expiry calendar. The clock has now been running thirteen days. The watch is whether OFAC issues a GL 134C extension before the cliff or lets it expire. The X stack has the answer half-priced from Bessent's earlier statement.

The mechanic is narrow. GL 134B authorizes "all transactions ordinarily incident and necessary to the unloading or offloading" of Russia-origin oil products that were already at sea on April 17, when the underlying sanctions designation under Executive Order 14114 took full effect. [2] It does not authorize new loadings, new contracts, or new financing. It is a closeout window for cargoes already in transit. The Baker McKenzie sanctions desk's analysis frames it as a technical extension of the orderly-wind-down convention OFAC has used since the 2014 Crimea sanctions; IndexBox's coverage emphasizes the administrative, not commercial, character of the license. [3]

What the X stack supplies is the political register the technical analysis omits. The Kyiv Independent's post quoted Treasury Secretary Scott Bessent saying "will not be renewing the general license on Russian oil," a statement made April 14 — three days before GL 134B was posted. [4] The discrepancy between Bessent's no-renewal posture and OFAC's actual issuance of a 30-day extension license tells the policy fight inside Treasury. Bessent's office has been pressing for clean-cliff enforcement; OFAC's career sanctions desk has been pressing for orderly-wind-down conventions to preserve the sanctions program's procedural legitimacy with allied jurisdictions. The 30-day window is the desk's win, with Bessent's no-renewal framing the political cover for what the cliff itself will be.

The market mechanic of the cliff is the secondary-market price of Russia-origin Urals trading from non-U.S. counterparties. Urals through April 25 traded approximately $9.20 below dated Brent; the discount widened to $11.40 by week-end as buyers priced in the cliff risk. The roughly $20-per-barrel total discount Urals carries against Brent now reflects both the price-cap regime (still $60/bbl, though widely circumvented) and the GL 134B cliff. If 134B expires without 134C, the discount widens further as European and Asian counterparties dump exposure to U.S. clearing risk; if a 134C is issued, the discount normalizes back toward $9–$10. The market is short-term agnostic and structurally pricing the cliff probability at approximately 60%.

The Iran-side comparison is also active. The U.S. Treasury's parallel "Economic Fury" sanctions package, issued the same week as GL 134B, targeted an Iranian shipping network run by Mohammad Hossein Shamkhani, the son of senior Iranian security official Ali Shamkhani. [5] The Treasury's X post characterized the action as part of a coordinated pressure campaign on the Iranian-Russian shadow fleet that has carried oil through both jurisdictions during the war period. The convergence is the operational story: OFAC is building a unified sanctions architecture that treats Russian and Iranian oil supply as analogous problems, with GL 134B's expiry and the Iran sanctions tightening as parallel pressure points.

What 134B does not cover is the Lukoil retail-station network. That carve-out is governed by a separate license, GL 128B, issued late 2025 and authorizing certain transactions involving non-Russia Lukoil retail gas stations until April 2026. [6] The Lukoil network in Europe, the Mediterranean, and Eastern Europe operates approximately 2,000 stations under brand and finance arrangements that depend on continuing OFAC permission. The Lukoil license has been extended twice already; whether it is extended a third time is a separate watch item that pairs with the 134B cliff for the European retail-fuel supply chain.

Sanctions Twitter has been handicapping the cliff at roughly 60-40 for hard expiry. The reasoning rests on Bessent's public framing, the Treasury's "Economic Fury" tightening on the Iran side, and the absence of allied lobbying for a 134C extension visible in the unclassified Treasury readouts. The 40% extension probability rests on the operational reality that twelve days remain for cargoes still at sea on April 17 to clear ports, and OFAC's institutional preference for orderly-wind-down architecture. Either outcome will be telegraphed by the Treasury's daily filings and the OFAC website's recent-actions feed.

The cliff is May 16 at 12:01 a.m. EDT. The last business day before is May 15. Treasury's call comes by the close that Friday.
