Lindsey O. Graham Act: 100% U.S. Tariff Threatens India’s Oil‑Import Strategy

On September 20, 2026, the U.S. Senate approved a law that will impose a 100% tariff on goods from any country that re among the five largest importers of Russian crude oil or natural gas after a 30‑day review period, directly targeting India. The measure is part of Washington’s strategy to pressure Russia’s energy revenues while reshaping global trade ties with major oil‑dependent economies. India’s exports to the United States, which surged 18% in the April‑August 2025 window, fell to a modest 3.8% growth through February 2026 after the tariffs took effect

•India’s crude‑oil basket now draws more than half its volume from Russia, and a new U.S.
•law could slap a 100 % tariff on all Indian exports if the country does not curb those purchases within 30 days.
•The move forces New Delhi to choose between higher import costs and a potential collapse of its export earnings to the United States.

India’s crude‑oil basket now draws more than half its volume from Russia, and a new U.S. law could slap a 100 % tariff on all Indian exports if the country does not curb those purchases within 30 days. The move forces New Delhi to choose between higher import costs and a potential collapse of its export earnings to the United States.

What the Act Mandates

The Lindsey O. Graham Sanctioning Russia and Iran Act—signed by President Donald Trump on 30 July 2026—authorises the U.S. Trade Representative, in consultation with the Secretary of State and the Secretary of Energy, to levy a full‑tariff on any nation that (i) ranked among the five biggest importers of Russian crude oil or natural gas in the preceding 12 months and (ii) continues those imports after a 30‑day grace period.

▸The tariff can reach 100 % of the customs value of goods originating in the target country.
▸The first review of qualifying importers must occur within 180 days of the initial tariff imposition.
▸The Act was amended to extend sanctions on Iran until 2031.

If India remains in the top‑five list—its share of Russian crude rose to >51 % in July 2026—the United States could immediately trigger the punitive duty on Indian merchandise destined for the U.S. market.

India’s Growing Dependence on Imported Oil

India’s oil‑import dependence, as measured by the Ministry of Petroleum and Natural Gas, climbed to 84.6 % in FY 2023‑24, up from 78.1 % in FY 2022‑23. The fiscal year’s import bill stood at ₹13.2 trillion, while the current‑account deficit widened to 2.1 % of GDP (RBI, 2024).

▸The National Energy Policy 2022 and the Hydrocarbon Exploration and Licensing Policy 2023 set a target of 60 % import dependence by 2030.
▸Domestic production contributed only 15.4 % of total crude consumption in FY 2023‑24.
▸The Strait of Hormuz bottleneck has limited alternative supply routes, raising the cost of rapid import adjustments.

These figures underscore the fiscal pressure of high‑priced imports and the vulnerability of India’s balance of payments to external shocks.

Lessons from the 50 % Tariff Episode

During the earlier punitive regime (August 2025 – February 2026), the United States imposed a 50 % tariff on Indian goods. Export data reveal a sharp slowdown after the tariff took effect.

▸Merchandise exports to the U.S. grew 18 % YoY in April‑August 2025, driven by front‑loaded shipments.
▸Over the longer window April 2025 – February 2026, export growth to the U.S. fell to 3.8 %, reflecting reduced competitiveness.
▸Exporters reported sharing up to 50 % of the tariff cost with American buyers to retain contracts.

The experience shows that even a half‑tariff erodes profit margins and can trigger a rapid decline in export volumes, a scenario that would be amplified under a full‑tariff regime.

Did You Know? In 2024, India voluntarily reduced oil purchases from Venezuela and Iran after earlier U.S. pressure, demonstrating its willingness to adjust import sources when faced with trade sanctions.

Macro‑Economic Ripple Effects

A 100 % tariff would double the landed cost of Indian goods in the United States, likely slashing demand for sectors ranging from textiles to pharmaceuticals. The resulting export contraction would worsen the current‑account deficit, already at 2.1 % of GDP, and could compel the Reserve Bank of India to tighten monetary policy, raising the repo rate.

▸A 10 % fall in export earnings could add ₹0.8 trillion to the fiscal deficit, pressuring the government’s FY 2025 budget.
▸Higher import bills for Russian crude would push the import bill beyond ₹14 trillion, inflating the trade deficit.
▸Energy‑price volatility would feed into consumer‑price inflation, threatening the RBI’s 4 % target.

These dynamics illustrate how a trade sanction on oil imports can cascade through fiscal, monetary and price‑stability channels.

Strategic Choices Ahead

India now faces a binary decision: (i) curtail Russian oil purchases to fall out of the top‑five importers and avoid the tariff, or (ii) absorb the tariff and bear the attendant economic costs. Reducing dependence would require accelerating domestic exploration under the Hydrocarbon Exploration and Licensing Policy 2023, expanding renewable capacity, and diversifying import sources through strategic petroleum reserves.

▸Achieving the 60 % import‑dependence target by 2030 would demand an annual 5 % increase in domestic output.
▸Strengthening the Petroleum Ministry’s strategic reserve could provide a buffer against short‑term supply shocks.
▸Engaging diplomatically with the United States to seek a waiver or phased‑in tariff could buy time for structural adjustments.

The path chosen will shape India’s energy security, fiscal health, and its standing in the evolving geopolitics of energy trade.
