Russia-related General License 134B expires at 12:01 a.m. EDT Friday, May 16 — eight days from Thursday's close, eight days after Pakistan's IMF Executive Board approval cleared, six days before Aramco's Sunday preliminary release lands. [1] No GL 134C has been pre-announced. OFAC's last week of substantive Russia-Iran sanctions architecture activity was its update to the Hormuz-toll FAQ guidance, which now states explicitly that "payments to the government of Iran or the Islamic Revolutionary Guard Corps (IRGC), directly or indirectly, for safe passage through the Strait of Hormuz would not be authorized for U.S. persons, including U.S. financial institutions, or for U.S.-owned or -controlled foreign entities." [2] The Russia-inside, Iran-outside enforcement architecture has, in the same operational week, hardened on both axes.

The May 7 paper opened the cliff at T-9 against the credibility line Bessent had crossed when his "we will not be renewing" pledge of April 15 was answered by OFAC's renewal April 17. Today's standard advances to T-8 with the architecture intact and the asymmetry sharpening. The April 17 license — replacing GL 134A — authorizes "the delivery and sale of crude oil and petroleum products of Russian Federation origin loaded on vessels as of April 17, 2026," extending sanctions wind-down for cargoes already in transit through May 16. [1] The carve-out language explicitly excludes "any transaction involving a person, entity or joint venture located in Iran, North Korea, Cuba, or parts of Ukraine." [3]

The volume the waiver covers is roughly 100 million barrels of Russian crude on tankers worldwide, per repeated public statements by Russian presidential envoy Kirill Dmitriev — a figure that survived the March 12 GL 134, the March 19 amendment to 134A, and the April 17 rollover to 134B. [3] The April 17 license is the third extension of a wind-down originally framed as transitional. The transitional framing has become persistent. Treasury's documentary architecture is now best read as a structural sanctions design — Russian crude inside an enforcement envelope, Iranian crude outside it — rather than a narrowing wind-down.

Treasury Secretary Scott Bessent has not addressed the architectural choice publicly since the April 17 reversal. His Wednesday $920 million crude-short timing question — raised in financial-press inquiries about whether the Treasury secretary's known equity positions had been fully divested before the April 17 license action — remains unanswered on the record. The May 16 cliff falls inside Bessent's first hundred days. A 134C extension would mark the fourth Russia-oil license action in nine weeks. A non-extension would produce immediate shipping-market disruption layered onto the Hormuz disruption already in progress.

Friday's exchange of fire in the Strait of Hormuz reopens the war-premium bid the cliff sits inside. Brent settled $102 Thursday after touching $96.75 intraday Tuesday; Friday's kinetic day pulled the curve back toward $103-$104 on early Friday electronic trading per Reuters wire reporting. The Hormuz-disruption premium and the Russia-waiver premium are running on the same tape, in opposite directions. A Russia-waiver lapse on May 16 would compound the Hormuz disruption. A Russia-waiver extension on May 16 confirms the architectural choice. Either move produces a price signal, and the price signal will be read inside the Iran-deal week.

The OPEC+ decisions sit on top. The cartel added 188,000 barrels per day for June. The OPEC+ Joint Technical Committee's June 7 communiqué will read whatever Treasury does on May 16 as a structural input to the cartel's volume calculus. If Russia stays inside the global market by virtue of GL 134C, OPEC+ has incentive to hold the June add and reassess at the June meeting. If Russia exits via lapse, OPEC+ has an opportunity to absorb a portion of the displaced Russian volume — at the cost of internal cartel discipline that has held since 2024.

The Treasury Hormuz-toll guidance update that landed last week is the cleanest indicator that OFAC's posture toward Iran is hardening even as its posture toward Russia accommodates. The IRGC-affiliated Persian Gulf Strait Authority has been issuing transit-permit demands at reported levels of $2 million per vessel, per CNN's documentary review of the Authority's invoicing. [2] Treasury's FAQ guidance is now explicit that any U.S. person or U.S.-controlled entity paying that toll exposes itself to enforcement liability. Shipowners with U.S. exposure now face a binary: pay Iran for transit and risk OFAC enforcement, or stay out of the strait. Most have stayed out. April Hormuz traffic per Lloyd's was 191 vessels against a 3,000-vessel monthly baseline. [4]

The Iran-deal week's architecture runs through these decisions in sequence. Saturday and Sunday absorb the Aramco preliminary release. Monday brings the Cole Allen prelim and Israel-Lebanon ambassador-level talks. Tuesday-Wednesday the Trump-Xi summit. Friday May 16 the GL 134B cliff. The waiver decision is the calendar's load-bearing sanctions event. Treasury has publicly committed to no posture in advance.

OFAC has issued three Russia-oil general licenses in nine weeks. The fourth is the one that defines the sanctions architecture the rest of the calendar runs through. The market is reading the silence.
