US President Donald Trump has announced a major change in the implementation of sanctions targeting Russia and countries purchasing Russian energy, offering temporary relief to several major oil-importing economies, including India.

On October 16, 2026, Trump signed an executive order waiving important sanctions, restrictions and tariffs under the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026.

The legislation, signed into law on September 18, introduced measures intended to increase economic pressure on Russia following its invasion of Ukraine.

One of its most significant provisions threatened additional tariffs of 100% on qualifying imports into the United States from major purchasers of Russian crude oil and natural gas.

The measures were scheduled to become applicable from October 18, making the timing of the waiver particularly important for international trade.

The executive order invokes Section 115 of the Graham Act, allowing the US president to waive specified measures after certifying that doing so serves the national interests of the United States.

For India, the decision reduces an immediate source of uncertainty surrounding its purchases of Russian crude oil and its broader trading relationship with the United States.

However, the waiver is not a permanent cancellation of the legislation, and Washington retains the authority to reconsider the suspended measures.

Another important distinction is that the threatened 100% duties concerned qualifying goods imported into the United States from targeted countries, rather than a universal 100% tax specifically on Indian refined petroleum exports.

India’s energy sector has become closely connected with Russian crude supplies since international trade patterns shifted following the outbreak of the Russia-Ukraine war.

Indian refiners increased purchases of Russian crude when commercially attractive cargoes became available, helping diversify the country’s sources of imported petroleum.

The economics of these purchases depend on crude quality, shipping expenses, insurance, payment arrangements and the discount relative to alternative international supplies.

Russian crude can offer a procurement advantage when its delivered cost is below that of comparable grades available from other producing countries.

However, a lower headline crude price does not automatically guarantee higher refining profits because processing costs, product yields and market conditions also matter.

The latest American waiver could reduce the immediate risk of new trade penalties influencing purchasing decisions by Indian refiners.

Nevertheless, existing US sanctions imposed under other legal authorities remain relevant, and the waiver should not be interpreted as unrestricted permission for every Russian energy transaction.

Reliance Industries is one of the most important listed Indian companies to monitor because of its extensive refining operations and exposure to international crude procurement.

Its Jamnagar refining complex processes different crude grades and produces petroleum products for domestic consumption and international markets.

Greater certainty around eligible crude purchases may provide operational flexibility, although Reliance’s actual financial benefit will depend on procurement economics and the applicable sanctions framework.

Indian Oil Corporation is another major company affected by developments in international crude oil markets.

As India’s largest state-owned oil marketing company, Indian Oil operates across refining, pipelines, petroleum marketing and other energy businesses.

Changes in crude sourcing conditions can influence its refinery feedstock costs, inventory requirements and working capital.

Bharat Petroleum Corporation also depends on international crude supplies for its refining operations.

For BPCL, procurement flexibility may help manage input costs, but its profitability will continue to depend on refining margins and domestic fuel marketing economics.

Hindustan Petroleum Corporation faces similar considerations because its financial performance reflects both refining operations and the marketing of petroleum products.

Investors should therefore distinguish between the possible benefits of sourcing flexibility and the broader earnings outlook of these companies.

Mangalore Refinery and Petrochemicals and Chennai Petroleum Corporation are additional listed refining businesses worth monitoring.

Their sensitivity to developments in Russian crude supply will depend on the crude grades they process, purchasing arrangements and refinery configurations.

A major issue for all refiners is the relationship between crude acquisition costs and the market value of finished petroleum products.

Gross refining margins measure the difference between the value of refined products and crude input costs before certain operating expenses.

If crude procurement costs decline while product prices remain relatively stable, refining margins may improve.

However, if international petrol and diesel prices fall simultaneously, the benefit from cheaper crude can be reduced.

The global oil market also remains exposed to disruptions involving shipping routes, producing countries and regional conflicts.

This is especially important for India because imported crude oil accounts for a substantial portion of its petroleum requirements.

High crude prices can increase India’s import bill and create additional demand for US dollars. Greater dollar demand can contribute to pressure on the Indian rupee, particularly when foreign capital flows are also unfavourable.

Currency movements can then influence the rupee-denominated cost of crude imports, creating another variable for refiners to manage.

A reduction in geopolitical trade uncertainty may improve business planning, but it does not guarantee lower crude prices or a stronger rupee.

Beyond oil companies, industries such as aviation, logistics, paints and chemicals are also sensitive to petroleum-related costs.

InterGlobe Aviation is an example because aviation turbine fuel represents an important operating expense for airlines.

Asian Paints and Berger Paints also face exposure to petroleum-derived raw materials, although their cost structures and pricing arrangements differ.

For these businesses, any improvement would depend on actual changes in input prices rather than the sanctions waiver alone.

The decision may also influence investor perceptions of Indian export-oriented businesses because the suspended tariff provisions extended beyond the petroleum sector.

Companies exporting goods to the United States could face less immediate uncertainty from the Graham Act’s additional country-based tariff threat.

However, other existing US tariffs and trade restrictions are unaffected by this particular waiver.

The next developments to monitor include US implementation guidance, Russian crude shipment volumes, oil-price movements and any subsequent changes to the waiver.

For investors tracking Reliance Industries, Indian Oil, BPCL, HPCL and other energy companies, the key question is whether reduced policy uncertainty translates into measurable improvements in procurement costs and profitability.

Trump’s October 16 decision provides temporary relief from a potentially disruptive set of new trade measures. Its longer-term significance will depend on future US policy, existing sanctions compliance and the direction of international energy markets.
