The US Treasury let its sanctions waiver for Russian seaborne oil purchases expire on May 16, closing a window that had allowed countries to buy Russian crude without triggering secondary sanctions. The Trump administration chose not to renew the temporary licenses, marking a harder line on energy enforcement against Moscow.

What the waiver actually did

The US issued General License 134, along with subsequent versions 134A and 134B, which permitted the delivery and sale of Russian crude and petroleum products that were already loaded on vessels by specific cutoff dates.

Around 10 countries had requested continued relief, citing supply risks tied to instability in the Strait of Hormuz. Treasury Secretary Scott Bessent responded by extending sanctions relief for an additional 30 days. That 30-day extension has now run its course, and no further renewal followed.

Bessent also pushed back on claims that Iran had benefited by more than $14B from related sanctions relief measures, though he did not provide an alternative figure.

Why this matters for global oil markets

The lapse creates a binary choice for oil-importing nations: stop buying Russian seaborne crude, or risk being hit with US secondary sanctions.

India has been one of the largest buyers of discounted Russian oil since Western nations began restricting purchases following the invasion of Ukraine. Losing access to those barrels, or paying a sanctions-risk premium to keep buying them, forces a recalculation of supply strategies across Asia.

The crypto angle: follow the macro breadcrumbs

Oil prices are one of the most important inputs into global inflation expectations. When crude rises, it feeds through to transportation costs, manufacturing, food prices, and eventually the Consumer Price Index readings that the Federal Reserve watches. Higher inflation expectations tend to delay rate cuts, which mean tighter financial conditions.

For crypto investors, the key variable to watch is not the sanctions themselves but the oil price response over the coming weeks. A sustained move higher in crude, particularly Brent, above recent ranges would signal that the supply tightening is real and not just theoretical.
