Trump Signs Lindsey Graham Sanctions Act Targeting Russia’s Oil Buyers and Iran Sectors

What Happened

On Friday, September 18, 2026, President Donald Trump signed the Lindsey O Graham Sanctioning Russia and Iran Act of 2026 into law after Congress passed the bill with bipartisan support.

The legislation, named for the late Senator Lindsey Graham (R‑SC) who co‑authored it with Senator Richard Blumenthal (D‑CT) before his death in July 2026, cleared the Senate last month and the House of Representatives on Wednesday, September 16, 2026, with 58 Democrats joining Republicans in favor.

The signing ceremony took place at the White House, marking the first major Ukraine‑related bill to become law in more than two years.

The bill’s provisions include sanctions on Russian leadership, financial institutions, energy and defense sectors, and a mechanism for tariffs on the top purchasers of Russian crude oil and natural gas.

What the Evidence Establishes

The Al Jazeera report states that the bill “sanctions Russian President Vladimir Putin, senior officials and oligarchs, along with Russian banks and financial institutions.”

It also notes that the legislation “targets Moscow’s energy and defence sectors and the so‑called shadow fleet of tankers used to move Russian oil around Western sanctions.”

The Hill article confirms that the law “authorizes the president to impose tariffs of up to 100 percent on the five largest buyers of Russian oil and gas,” a measure expected to affect China and India.

Both outlets record that Ukrainian President Volodymyr Zelenskyy described the bill as “an extremely powerful tool” and that House Speaker Mike Johnson said it placed “maximum pressure” on what he called “the Russian war machine.”

Where the Accounts Conflict

While supporters argue the sanctions will starve the Kremlin of war funds, House Minority Leader Hakeem Jeffries warned that the tariff authority could raise costs for American families and labeled the sanctions provisions “full of loopholes.”

In contrast, Indian officials said this week that the country “remains firmly committed to ensuring energy security for its 1.4 billion people,” signalling potential resistance to any U.S. tariffs on Russian oil purchases.

The sources do not provide a unified estimate of how much revenue Russia might lose, leaving the economic impact uncertain.

Context and Stakes

The legislation represents the first major congressional action on Ukraine since early 2024, reflecting renewed bipartisan concern over Russia’s continuing invasion.

It comes roughly one week before President Trump is scheduled to host Chinese President Xi Jinping at the White House, a meeting where the new tariff authority could be discussed.

Analysts note that similar sanctions packages in the past have produced mixed results, with some leading to negotiated settlements and others prompting retaliatory measures from targeted states.

The bill’s extension of sanctions on Iran’s energy and weapons sectors adds a second geopolitical layer, potentially influencing Tehran’s calculations amid ongoing nuclear negotiations.

What to Watch Next

Implementation of the tariff provision: observers will monitor whether the Trump administration publishes a list of the five largest Russian oil buyers and announces specific tariff rates within the next 30 days.

Potential counter‑measures: China and India may respond by seeking alternative energy supplies or by filing complaints at the World Trade Organization.

Congressional oversight: committees may hold hearings to assess whether the sanctions are achieving their stated goal of pressuring Putin toward negotiations.

Market reactions: energy traders will watch for shifts in crude oil prices and freight rates for the shadow‑fleet tankers as the sanctions take effect.

Bottom Line

President Trump has enacted a sweeping sanctions law that targets Russia’s war financing apparatus and grants the president broad tariff authority over top Russian oil consumers.

The law’s immediate effect will depend on how swiftly the administration defines the tariff targets and how Beijing and New Delhi choose to respond.

If the measures succeed in cutting Russian revenue, they could create incentives for a negotiated settlement; if they provoke significant retaliation or market disruption, the policy may face heightened scrutiny domestically and abroad.
