The U.S. Treasury extended its Russian seaborne oil sanctions waiver for a third consecutive month on May 18, with benchmark crude near $103 a barrel, underscoring how Strait of Hormuz disruptions are repeatedly overriding stated sanctions policy.
For long-horizon investors, the pattern of waiver-then-reversal signals that the sanctions architecture underpinning global energy risk pricing may be less durable than previously assumed, potentially compressing the risk premium embedded in oil-sector equities.
Key Takeaways
- Treasury issued General License 134B, extending Russian oil relief through June 2026.
- U.S. benchmark crude traded around $103 per barrel at the time of the extension.
- Secretary Bessent reversed course twice after publicly pledging to let the waiver lapse.
Market Reaction & Context
U.S. benchmark crude was up approximately 2% to around $103 a barrel on May 18, the day Treasury Secretary Scott Bessent confirmed the latest extension 1. That price level reflects the cumulative supply shock from an ongoing conflict involving Iran that has choked commercial traffic through the Strait of Hormuz for nearly three months.
The waiver saga began in March 2026 with the first issuance of General License 134A, which authorized delivery of Russian oil already in transit 2. That license expired April 11; a replacement – General License 134B – was issued April 17, running through May 16, before the third iteration extended relief into June 1.
Detailed Analysis
The recurring reversal pattern carries measurable implications for commodity traders, shipping insurers, and refiners who price Russian crude at a discount to Brent. Each extension narrows the legal uncertainty window but simultaneously signals that Washington’s willingness to enforce the full sanctions regime is conditional on oil-market stability.
Sanctions expert Brett Erickson of Obsidian Risk Advisors said the humanitarian logic Bessent invoked for the first extension made subsequent reversals structurally inevitable.
“He effectively cited ‘humanitarian reasons’ to justify the extension – we’re now almost a full month longer into the conflict, Hormuz is still closed, and the crisis for many Asian countries has only become exponentially worse. There’s really not another option.” 1
The license is narrowly drawn: it covers only oil already loaded aboard vessels as of the issuance date, providing a defined legal pathway for shipowners, insurers, and commodity traders to complete in-transit transactions 2. Critics, however, argue the repeated use of such instruments is progressively hollowing out the broader Russia sanctions framework built since February 2022.
Leading Senate Democrats – including Chuck Schumer, Elizabeth Warren, and Jeanne Shaheen – condemned each extension as a “180-degree reversal,” arguing the relief funnels additional revenue to Moscow’s war effort at a moment when Russia continues military operations in Ukraine 2. Fourteen Senate Democrats separately urged Bessent in late April to reinstate the full sanctions regime, calling the waiver “a mistake that President Trump must reverse immediately” 1.
Geopolitical Crosscurrents
Ukraine’s position adds a further layer of complexity for investors assessing sanctions durability. Vladyslav Vlasiuk, a senior adviser to President Volodymyr Zelenskyy, has argued that even temporary waivers translate into billions of dollars in additional revenue for Russia and questioned whether discounted Russian oil volumes are large enough to offset Hormuz-driven supply gaps 2.
On the Iran side, Treasury allowed a parallel waiver permitting Iranian oil sales to expire in April and has since issued new sanctions on so-called “teapot” refineries in China that process Iranian crude – an initiative Bessent dubbed “Operation Economic Fury” 1. President Donald Trump separately indicated he is considering lifting those refinery sanctions, adding another variable to the global supply equation 1.
Outlook
Matthew Murray, former deputy assistant secretary of commerce and now an adjunct professor at Columbia University and Georgetown University, framed the waivers as a calculated, if uncertain, balancing act. “The question now is whether President Donald Trump can successfully apply both carrots and sticks,” Murray said, suggesting selective relief may be intended to influence Moscow’s behavior 2.
For investors with exposure to energy infrastructure, tanker operators, or commodity-linked equities, the central risk is not the current waiver itself but the precedent: if Hormuz pressure persists or resurfaces, further extensions appear the path of least resistance, keeping a ceiling on the effective enforcement of Russia energy sanctions for the foreseeable future.
