How US sanctions on Russian energy could affect its trading partners

The House on 16 September 2026 cleared H.R.5334, a bipartisan package that tightens sanctions on Moscow and grants the president large tariff and waiver authorities — raising questions for allies, markets and enforcement.

U.S. House passes the Lindsey O. Graham Sanctioning Russia and Iran Act

On 16 September 2026 the House of Representatives approved H.R.5334, the Lindsey O. Graham Sanctioning Russia and Iran Act, sending the measure to President Donald J. Trump. The vote — 262 to 159 — ratified a bill that the Senate had cleared earlier and that backers say represents the most ambitious U.S. economic pressure campaign against Moscow since Russia’s full‑scale invasion of Ukraine.

The legislation combines expanded sectoral sanctions on Russian finance and leadership with new authorities to penalise purchasers of Russian energy. Crucially for transatlantic relations, it also grants the president broad waiver and tariff powers — including the ability to impose levies of up to 100 per cent on large importers of Russian crude and natural gas under specified conditions.

Why the bill matters now

H.R.5334 arrives at a sensitive moment for European energy security and global commodity markets. Proponents argue that targeting buyers of Russian energy will cut Moscow’s revenue streams and coerce a negotiated end to hostilities in Ukraine. The bill also extends certain Iran sanctions authorities, a measure that helped secure wider Republican support.

But the measure’s most geopolitically consequential feature is the tariff authority and an expansive waiver standard contained in the Senate amendments adopted by the House. That combination hands the White House a toolkit that could be used to compel behaviour by foreign states or to reward cooperation, while simultaneously raising the prospect of friction with allied governments and major trading partners.

Potential effects on allies and markets

European cohesion: Several European countries still depend on Russian gas and refined products. The threat of U.S. tariffs on purchasers could force EU governments into difficult trade‑offs between immediate energy needs and longer‑term pressure on Moscow.
Global trade partners: The bill names large importers of Russian energy among potential tariff targets. Analysts have noted that China and India — major buyers of Russian hydrocarbons — could be particularly exposed, which risks pushing two crucial geopolitical actors closer to Moscow in response.
Energy markets: The prospect of U.S. penalties on buyers risks volatility in oil and gas markets. Firms and states that have adapted to Russian supplies over the past years may face steep commercial and political costs if compelled to shift quickly.

These are not hypothetical concerns. Trade specialists and former administration officials have warned that tariff powers of the sort authorised in H.R.5334 could be applied flexibly, provoking spill‑over effects well beyond their intended targets. Scholarly and media analysis published as the legislation moved through Congress underlined the tension between coercive leverage and the need for allied coordination on sanctions enforcement.

Waivers, executive discretion and checks

The bill includes waiver provisions that allow the president to exempt countries or entities from sanctions or tariffs where the administration determines doing so is in the national interest and reports the decision to Congress. Critics in both parties cautioned during floor debate that the standard may be broad enough to permit selective application, potentially undermining the bipartisan impetus behind the measure.

Supporters counter that the waiver is necessary to retain diplomatic flexibility. They also point to reporting requirements intended to provide congressional oversight. In practice, however, oversight depends on Congress’s willingness and capacity to scrutinise the executive’s determinations — a dynamic that will shape how the law is used.

Immediate diplomatic questions

Allies in Europe will now be watching how quickly and in what manner the White House exercises the new authorities. Will the administration use tariffs primarily as a pressure instrument against Moscow and its major energy customers, or will it employ them selectively to extract concessions from partners on other issues? The answer will determine whether H.R.5334 strengthens coordinated pressure or becomes a source of transatlantic discord.

Likewise, major buyers in Asia will face a choice: acquiesce to U.S. pressure and diversify supplies at considerable short‑term cost, or resist and risk economic penalties that could compound diplomatic strains. Governments from Paris to New Delhi and Beijing will weigh those options with an eye to domestic energy needs and broader strategic priorities.

What comes next

The bill now rests with President Trump. The administration indicated support for the Senate amendment package when it moved through the upper chamber, and Republican and Democratic leaders have indicated the president is likely to sign the measure. If enacted, implementation will test the balance between U.S. unilateral leverage and the practical necessities of allied coordination on sanctions and energy security.

For policymakers in Washington and abroad, the immediate task will be to translate the statute’s broad authorities into a credible, coherent strategy that tightens pressure on Moscow without destabilising markets or rupturing partnerships that the United States needs to uphold long‑term pressure on Russian behaviour.
