US Treasury Extends Russian Oil Sanctions Waiver Amid Iran War Shortages

The U.S. Treasury Department extended a sanctions waiver for Russian oil shipments on April 18, 2026, to alleviate global supply pressures stemming from the Iran war, reversing a position taken just days earlier by Treasury Secretary Scott Bessent who had ruled out such an extension.

The extension, issued as a general license by the Office of Foreign Assets Control (OFAC), allows U.S. Sanctions to not apply for 30 days on deliveries of Russian crude oil loaded onto tankers as of April 18, 2026. This follows a similar 30-day waiver granted in March for Russian oil loaded by March 11, 2026, which was set to expire before the new extension.

According to OFAC documentation, the license specifically covers Russian oil that has been loaded onto vessels prior to the effective date, permitting its transport, insurance, and financing under U.S. Jurisdiction without triggering secondary sanctions, provided the cargo remains unchanged and is destined for non-U.S. Markets.

The decision marks a notable shift in U.S. Energy sanctions policy, coming after Secretary Bessent stated at the White House on April 16, 2026, that the administration would not renew either the Russian oil waiver or a parallel waiver for Iranian oil. “We will not be renewing the general license on Russian oil, and we will not be renewing the general license on Iranian oil,” Bessent said during a press briefing, offering no immediate rationale for the impending reversal.

Treasury officials did not publicly explain the change in position between April 16 and April 18. However, the timing coincides with heightened global oil market volatility following escalations in the Iran war, which began in early March 2026 and has disrupted shipping lanes in the Strait of Hormuz, a critical chokepoint for approximately 20% of global oil seaborne trade.

Analysts note that the waiver extension effectively allows Russia to continue exporting crude oil loaded before the deadline without fear of U.S. Punitive measures on third-party insurers, financiers, or port operators — a significant relief for Moscow’s energy revenue stream, which had been constrained since the 2022 invasion of Ukraine and subsequent G7 price cap and sanctions regime.

Prior to the extension, Russian oil exports faced growing logistical and financial hurdles due to the declining willingness of Western insurers and lenders to engage with cargoes linked to sanctioned entities, even when the oil itself was not directly restricted under secondary sanctions. The waiver helps mitigate these chokepoints by clarifying that certain pre-loaded cargoes remain permissible under U.S. Rules.

The move underscores the complex interplay between regional conflicts and global energy markets, where supply disruptions in one region — such as those caused by naval blockades, mine-laying, or port closures in the Persian Gulf — can prompt policy adjustments elsewhere to prevent broader economic strain.

As of April 18, 2026, Brent crude traded near $89 per barrel, up from $82 two weeks prior, reflecting market anxiety over Gulf supply stability. The extension does not authorize new Russian oil shipments to be loaded after the deadline under the waiver, nor does it lift any underlying sanctions on Russian state energy firms like Rosneft or Gazprom Neft, which remain subject to blocking sanctions and export restrictions.

U.S. Officials have not indicated whether further extensions will be considered beyond the 30-day window. The license is set to expire on May 18, 2026, unless renewed or modified by OFAC before that date.
