US allows waiver on Russian oil to expire, tightening global supply at the worst possible time

The US Treasury let its temporary sanctions waiver on Russian seaborne crude oil expire on May 16, effectively slamming the door on a relief valve that had been keeping some barrels flowing to energy-hungry buyers like India.

What the waiver actually did

The General License allowed the sale and delivery of certain Russian oil cargoes that were already at sea, giving buyers a narrow window to complete transactions without running afoul of US sanctions.

The waiver first appeared in March 2026, during a period when the Iran conflict was causing serious disruptions near the Strait of Hormuz. When one major oil chokepoint was under threat, Washington quietly opened a back channel to keep global supply from cratering.

But the license was never meant to be permanent. It went through a pattern of short-term extensions, expiring and getting briefly renewed. Treasury Secretary Scott Bessent had signaled that the waiver would not be renewed this time around, and he followed through.

This marks at least the second time the waiver has expired without renewal, but previous lapses were followed by extensions.

Why this matters beyond oil trading desks

The most immediate impact lands on countries that were the primary beneficiaries of the waiver, with India at the top of that list. Indian refiners had been among the largest buyers of discounted Russian crude, and losing that access forces them to compete for barrels from other producers in an already tight market.

Crude prices were already nearing the $100 per barrel mark due to supply concerns tied to the Iran conflict. Removing restricted Russian barrels from the equation adds further upward pressure.

The crypto connection

No specific crypto tokens were cited as being directly affected by the waiver expiration. However, historical correlations exist between commodity shocks and movements in digital asset markets.

Rising oil prices feed into higher inflation readings, which create uncertainty about central bank policy. That uncertainty increases volatility across risk assets, including crypto. If oil prices sustain above $100 per barrel, the inflation narrative could resurface in crypto markets, potentially benefiting Bitcoin’s store-of-value thesis while creating pressure on more speculative altcoins.
