Market investors are expected to closely monitor the implications of US President Donald Trump signing the Sanctioning Russia and Iran Act as crude oil prices and geopolitical developments are likely to influence equities this week. Last week, the BSE benchmark Sensex fell by 486.8 points, or 0.65 percent, while the NSE Nifty dipped by 51.7 points, or 0.22 percent.

Key Drivers of Market Sentiment

Analysts suggest that Indian equities will be influenced by several factors:

  • Crude oil prices
  • Global bond yields
  • Geopolitical developments

A new source of uncertainty has emerged regarding trade, particularly due to the expanded powers granted to the Trump administration to impose tariffs of up to 100 percent on imports from major buyers of Russian oil and gas, which includes India.

Details of the Sanctioning Russia and Iran Act

On September 18, 2026, President Trump signed into law H.R. 5334, the 'Lindsey O. Graham Sanctioning Russia and Iran Act of 2026'. This legislation:

  • Authorizes and expands sanctions on Russia and its energy sector.
  • Allows tariffs of up to 100 percent on countries purchasing Russian oil and gas, including China and India.
  • Comes into effect within 30 days of signing.
