President Donald Trump signed the Lindsey O. Graham Sanctioning Russia and Iran Act on September 18, 2026. This legislation introduces potential 100% duties on products from countries that continue to purchase Russian energy or violate sanctions.
Why it matters
The law introduces significant regulatory risk for importers that rely on supply chains within nations currently purchasing energy from Russia or Iran. It arrives alongside heightened geopolitical tensions, elevated bond yields, and persistent inflation pressures that complicate operational forecasting.
The legislation mandates duties reaching 100% on products from targeted nations, a shift occurring as the Federal Reserve raised interest rates to a 3.75%-4.00% range. These developments coincide with a 5.4% increase in producer prices for August 2026.
The players
Donald Trump
The current President of the United States who signed the new sanctions legislation into law.
Xi Jinping
The leader of China, a nation identified as a major buyer of Russian oil, scheduled for a diplomatic visit.
The details
The new law empowers the U.S. to impose massive tariffs on countries that sustain energy trade with Russia or Iran. For operators, this creates a compliance requirement to audit tier-one and tier-two suppliers for energy sourcing vulnerabilities that could trigger these duties. With producer prices already rising by 5.4% in August, any additional tariff costs will likely face pressure to be passed through to customers to protect margins.

Market Landscape
The introduction of the Lindsey O. Graham Sanctioning Russia and Iran Act intensifies the existing pressure from high interest rates and Middle East geopolitical volatility. This move signals a significant hardening of U.S. trade policy regarding global energy supply chains.
Operators must immediately review international supply chain dependencies to determine if any vendors reside in nations that purchase Russian energy. Consult with trade compliance counsel to assess potential exposure to the 100% duty threshold established by the new law.
The takeaway
The signing of this sanctions act adds a new layer of risk for businesses relying on global trade routes, especially regarding energy-dependent economies. Owners should audit their supplier contracts for tariff liability and prepare for potential price volatility resulting from the new trade duties.
What happens next
Potential interest rate hikes are expected to be considered by the Federal Reserve in October 2026.
