Sanctioning Russia and Iran Act: Economic Implications of Expanded Presidential Tariff Power

The Sanctioning Russia and Iran Act, which expands tariff authority to the U.S. President, threatens to destabilize global trade flows.

A New Pivot in Washington’s Trade Playbook

The legislation pushes Presidential Tariff Power beyond its traditional bounds, allowing up‑to‑100% duties. The congressional attempt to confine this power to a handful of nations appears to be a superficial fix rather than a robust policy solution.

Hidden Risks Behind the Limited Country List

■China and India are the top recipients of Russian energy exports; tariffs on these two markets could affect up to 30% of U.S. export revenue.

■Turkey imports roughly 20% of its natural gas from Russia, meaning indirect cost pressures could rise.

■Other G7 economies risk facing similar sanctions, injecting uncertainty into global supply chains.

Market Ripples from Past Tariff Waves

■The Trump tariffs of 2018‑2019 triggered a 5% decline in the S&P 500 index.

■Agriculture and technology sectors bore the brunt, with Apple and Intel shares slipping 7% and 9%, respectively.

■Currency markets saw the USD/EUR pair climb 0.02 units following the tariff announcements.

What Investors and Corporations May Face

■Profit margins: New duties could lift logistics and air‑cargo costs, eroding operational margins by 2‑3%.

■Supply chain: Customs delays in China‑U.S. trade could shrink air‑freight volumes by 15%.

■Financial markets: Tariff news tends to boost equity volatility by 10%, raising risk premiums.

Expert Insight (Gökberk Uçar): Extending tariff authority to the executive will generate cost shocks across global supply chains, with air freight being a primary conduit. Hubs such as Istanbul Airport may need to raise cargo rates by 12‑18%, a pass‑through that will feed higher consumer prices and add inflationary pressure.
