US Treasury allows sanctions waiver on Russian seaborne oil to lapse

The US Treasury has let its sanctions waiver on Russian seaborne oil cargoes quietly expire, closing one of the last remaining legal windows for Russian crude to move through international shipping channels. The waiver, known as General License 134B, lapsed as of May 16, 2026, with no renewal notice posted.

What the waiver actually did

General License 134B was issued back in April, and it served a very specific purpose. It allowed vessels that had already loaded Russian-origin oil before a certain cutoff date to complete their deliveries without running afoul of US sanctions.

The groundwork for this moment was laid months ago. Back in March 2025, the lapse of a related license, General License 8L, restricted financial transactions tied to Russian energy. That move alone contributed to a measurable decline in Russian seaborne crude export volumes, as banks and shipping companies grew increasingly cautious about touching anything connected to Russian oil.

Why the timing matters

Global oil supply chains are already strained by continued disruptions in the Strait of Hormuz, one of the most critical chokepoints for energy shipments worldwide. Roughly a fifth of the world’s oil passes through that narrow waterway on any given day.

The revised sanctions approach reflects a broader strategic posture that has been building for some time. The Trump administration initiated this campaign to systematically constrict the financial channels that Russia uses to monetize its energy exports.

What this means for investors

For crypto investors specifically, the dynamic is worth watching closely. Periods of tightening monetary policy and rising inflation have historically driven increased interest in non-sovereign assets. Bitcoin, in particular, tends to attract attention as a potential hedge when traditional financial systems face stress from geopolitical disruptions.

What to watch from here: whether any new waiver or license emerges in the coming weeks, how Russian crude export volumes respond to the lapse, and whether oil prices begin reflecting the tighter supply picture.
