# Brent slips to $105 as Trump's Russian diesel deal offsets Gulf supply fears

A bipartisan group of senators says the deal breaks the 2022 ban on Russian energy imports, even as the promise of 800,000 tons of Russian diesel pulls prices back from a four-week high.

Brent crude futures [fell 61 cents, or 1.05%, to $105 a barrel](https://m.economictimes.com/markets/commodities/news/oil-price-today-october-13-crude-oil-falls-to-105-as-traders-assess-russian-supply-mideast-attacks-whats-next/articleshow/134906049.cms) in Asian trading on Tuesday. West Texas Intermediate fell 92 cents to $93. Brent had settled at $106.65 on Monday, its highest close since September 15, according to the Economic Times, which put the gain in crude prices this year at more than 70%. Traders weighed the prospect of [more Russian diesel against continued attacks in the Gulf](https://www.investing.com/news/commodities-news/oil-ticks-lower-as-russia-diesel-supply-prospects-counter-gulf-supply-risks-4945271).

The diesel came from a call between President Donald Trump and Russian President Vladimir Putin. Trump said Russia would "immediately supply" [more than 300,000 tons of diesel](https://www.cnn.com/2026/10/11/politics/us-russia-diesel-deal-bipartisan-criticism), with another 500,000 tons promised for November. The deal requires the United States to ease sanctions on those Russian barrels.

Four Republican and three Democratic members of the Senate Foreign Relations Committee [urged Trump to "immediately reverse course"](https://en.mercopress.com/2026/10/12/republican-senators-urge-trump-to-cancel-the-putin-diesel-deal-as-unlawful?utm_source=feed&utm_medium=rss&utm_content=main&utm_campaign=rss). They argued that the deal breaks the 2022 law that banned imports of Russian energy. Senator Thom Tillis, a Republican from North Carolina, told NBC News there is a ["legitimate case for saying the president's not following the law."](https://www.nbcwashington.com/news/national-international/senators-demand-trump-immediately-reverse-course-russian-diesel-plan/4166232/)

The volumes involved are small relative to global demand, but the product matters more than the volume. Diesel powers freight transport and farm machinery, and shortages of it reach consumers' costs faster than shortages of most other fuels. The administration has chosen lower pump prices over the sanctions regime that Congress wrote. Moscow gains export revenue and a precedent for further waivers.

## What this means

The channel runs through refined-product margins. Russian diesel returning to Western-linked markets narrows the premium of diesel over crude, which hurts refiners that earned high margins from the shortage and helps freight, airline and agricultural users. Russia gains revenue and a negotiating lever. The market has priced the first 300,000 tons. It has not priced the possibility that the waiver becomes a routine tool every time pump prices rise before an election. The consensus treats congressional anger as a constraint, but Congress has rarely forced a president to reverse an energy waiver quickly. The 2022 license that let Chevron resume Venezuelan oil output followed the same path: it started narrow and was renewed and widened over time. The likelier outcome over the next few months is that the November tranche goes ahead and further Russian product waivers follow, as long as Brent stays above $100. A court injunction or a veto-proof vote in Congress to block the deal would prove this forecast wrong.

## What to watch

- Whether the second, 500,000-ton November shipment is confirmed: delivery would show that the waiver is becoming a supply channel, not a one-time gesture.
- The gap between diesel and crude prices in Europe and the US Gulf Coast: a sustained narrowing would show the Russian supply is reaching buyers.
- Any lawsuit or binding Senate measure against the deal: that is the only route by which Congress can actually stop the imports.
