Trump Signs Russia Sanctions Bill to Cut Moscow's Ukraine War Funds

President Trump signed sweeping Russia sanctions legislation Thursday, a move the White House framed as a major step toward cutting off the financial flows that sustain Moscow’s war in Ukraine, WCVB reported.

The legislation carries a provision that Reuters described as giving Trump “sweeping new tariff powers” — authority that goes beyond direct sanctions on Russian entities and extends economic leverage to third-party countries that continue doing business with Moscow.

What the Bill Does

The sanctions component targets Russian entities and individuals and is consistent with the broader framework of restrictions the United States and its allies have imposed on Russia since the 2022 invasion of Ukraine. What distinguishes this legislation, according to Reuters, is the accompanying tariff authority.

Tariff powers allow the executive branch to levy duties on goods from countries that trade with sanctioned parties. In the context of Russia policy, this mechanism would give the administration a graduated tool to pressure nations that have continued purchasing Russian energy exports, weapons components, or other sanctioned goods — stopping short of formally sanctioning those countries but imposing a measurable economic cost on continued trade.

The provision addresses a persistent gap in the existing sanctions architecture. Prior rounds of Western sanctions have demonstrated that Russia can partially offset their impact by redirecting exports toward non-Western markets. Secondary pressure tools — whether tariffs or the threat of them — are aimed at narrowing that exit.

A Shift in Posture

The bill’s signing is notable given the Trump administration’s record on Ukraine. Trump campaigned in part on skepticism toward open-ended U.S. support for Kyiv, and his administration has pursued negotiations aimed at ending the conflict through a brokered settlement. Those talks have stalled. A U.S. envoy’s approach generated frustration in both Moscow and Kyiv as of September 18, according to earlier reporting.

Signing sweeping sanctions legislation while peace negotiations remain deadlocked signals that the administration is willing to sustain economic pressure on Russia even absent a diplomatic resolution. Whether the tariff powers will be deployed — and against which trading partners — remains to be seen.

The Russia Sanctions Landscape

Thursday’s signing adds to an expanding set of economic restrictions against Moscow. Separate legislation targeting Russia’s Arctic oil sector was reported September 18, with sanctions aimed at the Vostok oil project, a major source of Kremlin revenue. Coverage of those developments is here.

Russia has continued its military campaign in Ukraine through the sanctions period. Missile and drone attacks on Kyiv were reported as recently as September 18, and Moscow held elections earlier this month in what analysts described as a test of domestic support for the war.

The relationship between the Trump administration and Russia has been complicated by separate reporting on potential business ties that critics say create conflicts of interest in U.S. policy toward Moscow — an argument the administration disputes.

Market and Diplomatic Implications

Russia is a major global supplier of oil, natural gas, and industrial metals. Sanctions legislation and the threat of tariffs on countries that continue trading with Moscow tend to move commodity markets, as traders reprice supply-chain risk.

The tariff authority, if exercised, would place a difficult choice before countries like China and India that have expanded Russian energy imports since 2022. Both have so far resisted Western pressure to curtail that trade. Formal tariff threats backed by statutory authority may represent a harder line than prior diplomatic requests.

Moscow is expected to respond to the legislation through official channels. Russia has consistently characterized Western sanctions as illegitimate economic warfare and has taken countermeasures including restrictions on foreign investment withdrawals and export controls on certain commodities.

What to Watch

The administration has not announced a timeline for deploying the new tariff authority or specified which trading partners are in scope. Congressional reaction — including from members who may have sought stronger or weaker provisions during the legislative process — will shape the political durability of the approach.

Diplomatic responses from Beijing, New Delhi, and Gulf state capitals, all of which have maintained Russian trade ties, will indicate how seriously the secondary pressure tool is being taken. Energy market pricing in the days following the signing will reflect early trader assessments of enforcement probability.

The bill’s passage and signing come as the broader geopolitical landscape around Russia and Ukraine remains volatile, with no negotiated ceasefire in sight and military operations on both sides continuing at significant tempo.
