Stock markets today: Sensex, Nifty tank as US-Iran uncertainty, crude oil prices weigh on investor sentiment
Indian benchmarks fell in early trade as US-Iran negotiation uncertainty, higher crude prices and foreign selling weighed on sentiment. The BSE Sensex dropped 699.74 points to 73,959.48 and the Nifty fell 177.40 to 23,302.50. Brent rose 0.89% to $96.85/bbl. FIIs sold equities worth Rs 8,362.92 crore on Tuesday, exchange data showed.

Price action likely reflects positioning unwind in Indian IT rather than new Infosys news.
Infosys is named among Sensex laggards as IT stocks fall sharply after a recent rally.
Choppy-to-lower near term until risk sentiment stabilizes.
Background
The piece frames India’s early-session decline around US-Iran negotiation uncertainty, a Brent crude spike toward ~$97, and continued foreign equity selling. It also adds a US Trade Representative proposal for additional forced-labor import duties affecting 54 countries including India.
Why it matters
The dominant drivers are macro/geopolitical and flow-based, implying broad beta pressure on Indian equities—especially IT—while some large caps show relative strength.
Market relevance
For traders, the actionable signal is a macro-driven risk-off open in India with IT underperforming and oil/geopolitics headlines likely to drive intraday volatility.
Market effects
Indian IT stocks face heightened downside risk from profit-taking and risk-off flows; oil strength reinforces macro pressure across cyclicals.
India underperforms on foreign outflows despite mixed Asia tape (Japan higher, Hang Seng lower).
US trade policy (forced-labor duties) and West Asia tensions can spill into global risk sentiment and commodity pricing, feeding into EM equity volatility.
Alternative perspectives
Gainers within the Sensex (Maruti, Adani Ports, Asian Paints, Airtel) may indicate selective rotation that can limit downside if crude stabilizes.
The article cites FIIs selling on Tuesday; intraday reversal is possible if oil cools or US-Iran headlines improve, but no hedging levels are provided.
