The Trump administration let a waiver encouraging Russian crude oil sales expire on April 11, sparking immediate anxiety about global supply constraints. Then, after Treasury Secretary Scott Bessent publicly declared on April 16 that the US would not renew waivers for Russian or Iranian oil, the administration did an about-face just two days later and issued a brand new one.

The fresh waiver, announced April 18, permits purchases of Russian oil loaded from that date through May 16. The license specifically excludes transactions involving Iran, Cuba, and North Korea.

The policy ping-pong, explained

Here’s the timeline. The original general license for Russian oil sales expired on April 11. That license had allowed Russian crude loaded by March 12 to continue being sold and settled through the financial system without triggering sanctions violations.

When it lapsed, the market held its breath. Five days later, Bessent appeared to settle the question by saying the US would not extend the waivers. Then came the reversal. On April 18, Treasury issued a new month-long waiver. The rationale, according to the administration’s framing, was to alleviate surging energy prices driven by broader geopolitical tensions and tighter global supply caused by restrictions on Iranian oil.

Why crypto traders are paying attention

Crude oil prices are one of the most direct inputs into consumer inflation. When supply gets tighter, oil prices rise, which feeds into transportation costs, manufacturing costs, and eventually the headline CPI numbers that the Federal Reserve watches when setting interest rate policy.

Interest rates, in turn, are arguably the single most important variable for risk assets. That includes crypto. Higher rates make yield-bearing instruments like Treasury bonds more attractive relative to speculative assets. Lower rates do the opposite, pushing capital further out on the risk curve toward things like BTC and ETH.

The May 16 cliff and what to watch

The new waiver runs through May 16. If it genuinely expires, removing Russian crude from accessible supply channels, even partially, could tighten an already nervous global oil market. The waivers were originally designed to ease shortages caused by Iranian restrictions, so pulling back on Russian supply while maintaining pressure on Iran creates a compounding effect.

There’s also the revenue question that makes this genuinely difficult policy. Every barrel of Russian oil that flows under a waiver generates income for Moscow. The entire point of sanctions is to restrict that revenue stream. By repeatedly extending waivers, the US is effectively funding one side of a conflict it’s trying to contain through economic pressure.

For crypto market participants, the key metric to track isn’t really oil prices themselves. It’s how oil price movements shift inflation expectations, particularly the 5-year breakeven rate and similar forward-looking measures. Those expectations influence Fed rate path projections, which in turn move Treasury yields, which ultimately affect how much capital flows into risk assets like Bitcoin.
