Punitive Tariffs On Russian Oil Purchase

The US House of Representatives on Wednesday passed the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026 by 262-159, after the Senate approved it 86-11, giving US President Donald Trump the authority to impose punitive tariffs (up to 100%) on major purchasers of Russian oil and gas, including India and China. The legislation still requires Trump's signature and does not automatically impose a 100 percent tariff.

If Washington uses the new authority to force a rapid reduction in Russian crude purchases, India could face higher global oil prices, a larger import bill, renewed pressure on the rupee, weaker corporate margins and slower growth. At the same time, Indian exporters could face sharply higher barriers in the US market.

The result would be an unusual double squeeze: energy costs could rise just as access to India's biggest export market becomes more expensive.

India's Ministry of External Affairs said Thursday that the government had already raised the issue with US interlocutors and had "very clearly articulated" its potential implications for both bilateral relations and international energy markets. "India remains firmly committed to ensuring energy security for its 1.4 billion people and will continue to pursue it through diversified sources of supply based on market dynamics," the ministry said.

But will Washington really deploy such a tariff weapon? Economists are divided on this question. 

The answer lies in the arithmetic. India imports more than 90% of its crude requirements. Russia accounted for 50.83% of India's crude imports in July, equivalent to about 2.47 million barrels per day. Between April and July, Russia's average share was 43.25%.

Earlier, Gulf producers supplied more than half of India's crude. Then, Russian barrels, offered at discounts after Western buyers withdrew from the market, allowed Indian refiners to diversify while lowering feedstock costs. West Asia's share of India's crude imports subsequently fell to about 30% in April-July from 43% a year earlier, while Latin American supplies rose to 12.7%.

The problem now is that alternative supply exists, but replacing Russian volumes quickly and at comparable economics is another matter.

Global Prices

Indian refiners can turn to Iraq, Saudi Arabia, the UAE, the US, Brazil, Venezuela, and other producers, but an abrupt shift by one of the world's largest crude importers would itself alter global prices.

That is precisely why economists are questioning whether Washington will actually deploy the maximum tariff weapon. Gaura Sen Gupta, Chief Economist at IDFC First Bank Economics Research, said, "In our base case we don't think it will be implemented as it would restart the tariff tensions between the US and other countries."

She also pointed to the geopolitical contradiction embedded in the measure: countries have increased Russian purchases partly because of disruptions caused by the West Asia crisis, while forcing India and China simultaneously to retreat from Russian crude could produce substantial upward pressure on international oil prices. "Given the current elevated levels of crude oil prices, we don't think this measure will be implemented," Sen Gupta said.

Brent is hovering around US$105 a barrel, with West Texas Intermediate (WTI) near US$102, while India's crude basket has been substantially higher amid regional supply disruptions.

Against that backdrop, forcing India to replace Russian barrels would amount to introducing an additional supply shock into an already strained market.

The immediate macroeconomic consequence would be felt in India's external accounts. India's crude import bill rose 25.8% year-on-year to US$ 16.69 billion in August, when its crude basket averaged US$ 90.19 a barrel; the average had risen to US$ 109.76 in September in the latest government data cited in the source material.

The broader current-account position is already deteriorating. Dharmakirti Joshi, Chief Economist at Crisil, said India's current account deficit widened to US $4.2 billion, or 0.5% of GDP, in the first quarter, from US $3.4 billion, or 0.4%, a year earlier. 

The merchandise trade deficit widened even more sharply, to US $86.1 billion from US $68.9 billion, as imports rose on the back of higher commodity prices.

India's Current Account Deficit

Crisil expects the current account deficit to widen to 1.5% of GDP this fiscal year, from 0.6% last year, with elevated oil and commodity prices keeping the import bill high, while global trade disruptions weigh on goods exports.

"Elevated crude oil prices are likely to exert additional pressure on the current account," Joshi said, forecasting Brent at an average of $82-$87 a barrel for the fiscal year, around 20% higher than last fiscal year. Oil accounted for 36% of India's total goods trade deficit last fiscal year, he said.

The significance of those numbers is that the US measure could widen India's external deficit even if the country succeeds in maintaining physical crude supplies: India would simply be paying more for replacement barrels.

The current account shock would not remain confined to the external sector. "If import volumes decline, it would pose downside risk to growth as ability to source crude will get impacted," Sen Gupta said. "A jump in global prices would impact company margins. Moreover, the drag from net imports will rise."

That creates a potentially damaging chain reaction.

Impact On Prices

Higher crude prices would raise the cost of transportation, petrochemicals, plastics, packaging, and industrial inputs. Refiners would face higher feedstock and freight costs. Manufacturing companies would have less room to absorb higher input costs, particularly in sectors operating on thin margins.

At the national-account level, more expensive imported energy would increase the drag from net imports, while weaker industrial margins could restrain investment.

Aditi Nayar, Chief Economist at ICRA, said, "Any imposition of higher tariffs by the US, and the associated uncertainty, would cast a downside on Indian growth prospects."

That uncertainty could itself become economically relevant. Companies do not need to face a 100% tariff for investment decisions to change; uncertainty over market access, product coverage and future US trade action can cause exporters to delay capacity expansion or redirect investment.

The other side of India's vulnerability is trade. The US was India's largest export destination in 2025-26, while Indian goods exports to the US reached US $42.79 billion in April-August 2026, compared with US $40.39 billion a year earlier.

The sectors exposed to a punitive tariff are not confined to a single industry. The same crude shock that raises costs for Indian manufacturers could be accompanied by a tariff shock that reduces their access to American consumers.

For smaller exporters, where margins are already limited, absorbing a substantially higher tariff may not be possible. Larger companies may attempt to redirect shipments to Europe, West Asia, Africa or other markets, but such diversification cannot be achieved instantly and could require price discounts.

Trade Negotiation

Ajay Srivastava, founder of the Global Trade Research Initiative, sees the sanctions legislation as potentially becoming leverage in the broader India-US trade negotiations.

"Washington may use the tariff threat to pressure India to reduce Russian oil purchases and accept a deeply unequal trade agreement," Srivastava said.

That raises a broader policy concern for New Delhi: whether a concession made on energy imports today would create a precedent for future US demands on India's trade, industrial or strategic policies.

The immediate issue is therefore not simply whether India can afford to stop buying Russian crude. It is whether the economic cost of doing so rapidly would exceed the cost of managing US tariff pressure while retaining a diversified crude portfolio.

Refiners In A Spot

Indian refiners sit at the center of this dilemma because Russian crude is both a geopolitical issue and a commercial input. The value of Russian oil to India has never been simply its availability. Discounts, freight costs, insurance, crude quality and refinery configurations determined whether a particular Russian grade was economically attractive.

A forced reduction would therefore not mean simply replacing one barrel with another.

Refiners would need to alter crude blends, secure alternative grades and potentially pay higher freight and insurance costs. If the replacement crude is more expensive, refinery margins would come under pressure unless higher costs can be passed through to customers.

The problem is compounded by the West Asia crisis, which has already disrupted conventional supply routes. India's experience during earlier supply disruptions demonstrates the role Russian crude has played as a hedge: when Middle Eastern supplies weakened, Russian shipments rose, reaching about 2.64 million barrels per day in June, almost half of India's total imports.

Rupee Pressure, China Factor

A larger oil bill would also increase India's dollar requirement. That could put additional pressure on the rupee, which in turn would raise the local-currency cost of imported crude and reinforce inflationary pressures. 

The effectiveness of the US strategy will also depend heavily on China. India is a major Russian crude buyer, but China is an even larger market. If both countries materially reduce purchases, Russian barrels would need to find alternative destinations while India and China compete for replacement supplies.

That is why Sen Gupta expects substantial upward pressure on global crude prices if the two Asian buyers shift away from Russian oil. For India, this means that even a decision to comply with US pressure may not insulate the economy from the oil shock it is designed to avoid.

What India Can Do

India's diversification options are real but constrained. But replacing more than 2 million barrels a day at short notice without pushing prices higher is a fundamentally different proposition.

The strategic objective, therefore, is likely to be diversification rather than abrupt substitution. That would allow Indian refiners to reduce exposure to any single supplier while avoiding a sudden demand shock in alternative markets.

The legislation's potential 180-day adjustment period, subject to presidential discretion, could give Indian refiners and policymakers some time to restructure procurement, negotiate waivers, and assess the final tariff architecture.

But the economic variables are already moving.

Crude prices are elevated. India's current account deficit is projected to widen. Inflation has moved above the RBI's target. The oil import bill is rising. At the same time, the US market remains central to India's export strategy.

Period Of Uncertainty

This is why the most consequential question for India may not be whether Trump has the legal authority to impose a 100% tariff, but whether Washington actually uses that authority at a time when the resulting oil-market shock could impose costs on India, China and other net energy importers while simultaneously disrupting American trade relations with major economies.

For New Delhi, the immediate task is consequently a delicate one: retain access to competitively priced crude, accelerate diversification, protect exporters from a sudden loss of U.S. market access and negotiate with Washington without converting temporary tariff relief into a structural constraint on India's energy choices.
