Trump signs Russia sanctions bill into law
A new US statute, the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026, was signed into law on 18 September 2026, after clearing the Senate in August and the House in mid-September.
The law authorises the US President to impose tariffs of up to 100% on the five largest purchasers of Russian crude oil or natural gas, or on the top five facilitators of Russian sanctions evasion — a category that includes India and China as the two largest importers of discounted Russian crude since 2022.
Beyond the tariff provision, the Act codifies sanctions on Russian government officials, financial institutions, defence-linked entities, and the "shadow fleet" of tankers used to move sanctioned oil, and extends the existing Iran Sanctions Act framework for five years.
The legislation is named for the late US Senator who championed it before his death in 2026, giving the President discretionary — not mandatory — authority to impose the tariffs.
Secondary Sanctions and Extraterritorial Jurisdiction
Secondary sanctions are measures a country imposes not on its adversary directly, but on third-party states or entities that continue to trade with that adversary — extending the sanctioning country's domestic law beyond its borders (extraterritorial application). This is distinct from primary sanctions, which restrict the sanctioning country's own nationals and companies from dealing with the target.
Key Details
- The US pioneered large-scale secondary sanctions through the Iran and Libya Sanctions Act (1996) and later CAATSA (2017), which created secondary-sanctions exposure for transactions with Russia's defence and intelligence sectors under Section 231.
- Secondary sanctions are controversial under international law because they apply US domestic legal consequences (tariffs, asset freezes, banking restrictions) to entities and states that have no jurisdictional nexus to the US beyond a transaction with the target country.
- They differ from UN Security Council sanctions, which are binding on all member states under Chapter VII of the UN Charter; unilateral secondary sanctions bind no one directly but coerce compliance through market access risk.
The new Act's oil-tariff mechanism is a textbook secondary sanction — it does not restrict US trade with Russia (already minimal) but instead penalises third countries like India for their trade with Russia, extending US foreign policy leverage extraterritorially.
CAATSA and the Precedent of Discretionary Presidential Sanctions Authority on India
The Countering America's Adversaries Through Sanctions Act (CAATSA), signed into law on 2 August 2017, is the earlier landmark US statute consolidating sanctions on Russia, Iran, and North Korea. Its Section 231 exposed any country conducting a "significant transaction" with Russia's defence sector to secondary sanctions — the provision under which India's 2018 purchase of the Russian S-400 air defence system has remained a standing, unresolved sanctions risk.
Key Details
- Under CAATSA, the US sanctioned Turkey's Presidency of Defence Industries in December 2020 over its S-400 purchase and removed Turkey from the F-35 fighter programme — the only instance of CAATSA Section 231 sanctions being actually imposed on a US partner.
- India has never been sanctioned under CAATSA for the S-400 deal; successive US administrations have used the President's discretionary waiver authority under CAATSA Section 231, citing the US-India strategic relationship.
- Like CAATSA, the 2026 Act gives the President discretion ("may impose") rather than a mandatory obligation to act, preserving room for diplomatic negotiation before any tariff is triggered.
The 2026 Act follows the same legislative architecture as CAATSA — Congress creates a broad sanctions/tariff authority, and the President retains discretion over whether and when to invoke it against a specific partner like India, making the actual outcome a matter of bilateral diplomacy rather than automatic law.
India's Crude Oil Import Diversification and Strategic Autonomy
India imports roughly 85-88% of its crude oil needs and diversified sourcing sharply toward discounted Russian crude after 2022, when Western buyers shunned Russian oil following the invasion of Ukraine. India's official position, reiterated by the Ministry of External Affairs, is that energy security for a population exceeding 1.4 billion is a sovereign policy priority, consistent with India's longstanding doctrine of "strategic autonomy" — engaging multiple powers without full alignment to any bloc.
Key Details
- Russia rose from a marginal supplier (under 2% of India's crude imports pre-2022) to India's largest single source of crude oil in recent years, overtaking Iraq and Saudi Arabia, on the back of price discounts.
- India has consistently argued that its Russian oil purchases do not violate any UN Security Council sanction (there is no UN embargo on Russian oil), distinguishing them from the unilateral US/EU measures.
- The G7 price cap mechanism (since December 2022) sets a ceiling on Russian oil prices for services like insurance and shipping provided by G7-linked firms, operating alongside — but separately from — the tariff threats in the new US Act.
The Act's 100% tariff threat is aimed squarely at reversing India's (and China's) diversification toward Russian crude, testing whether India's strategic-autonomy posture can hold against direct economic coercion from a major trading partner.
- The Lindsey O. Graham Sanctioning Russia and Iran Act of 2026 was signed into law on 18 September 2026.
- It authorises tariffs of up to 100% on the five largest buyers of Russian oil/gas or top sanctions-evasion facilitators.
- CAATSA, the precedent statute, was signed on 2 August 2017; its Section 231 covers significant transactions with Russia's defence/intelligence sectors.
- India imports approximately 85-88% of its total crude oil requirement; Russia has been its largest crude supplier since the 2022 price-discount shift.
- The Act also extends the Iran Sanctions Act framework for five years.
