Market Overview: The index opened high and surged, with gains later retreating.
On Tuesday, the Indian stock market shot up quickly at the opening: the Nifty 50 initially soared by about 5%, then pared its gains to around 3%; the Sensex also rose over 5% in early trading.
According to Reuters statistics, both the Nifty and Sensex intraday gains were around 2.8%, marking one of the largest intraday gains in nearly five years.
Key Catalyst: Tariff Reduction and Withdrawal of "Punitive Tariffs"
The immediate trigger for the market came from trade news: U.S. President Donald Trump announced an arrangement with Narendra Modi's government to reduce tariffs on Indian goods to 18% and to withdraw previously imposed additional punitive tariffs related to Russian crude oil purchases (which had compounded to as high as about 50%).
Leading the Surge: Export Chains and Heavyweight Stocks Fuel Broad Rebound
From the sectoral perspective, this rally resembles a "resonance of export and foreign capital-sensitive industries": sectors related to automobile parts, textiles, and engineering products, which are linked to exports, are considered among the main beneficiaries.
Among heavyweight stocks, Reliance Industries led gains intraday, further bolstering the indices.
Rupee and Capital Flows: Currency Strengthens, Market Bets on Foreign Capital Return
With risk appetite recovering, the rupee rose by over 1% against the dollar, which the market interpreted as a simultaneous reflection of "cooling trade uncertainties and expectations of capital return."
Reuters mentioned that since early 2025, due to high tariffs, a weak rupee, and lackluster earnings expectations, net foreign outflows had accumulated to about $23 billion; this news is seen as a key turning point in reversing capital sentiment.
Still Need to Watch: Implementation Details, Import Substitution, and Inflation Costs
Although the arrangement is viewed as "majorly positive" by the market, analysts still caution that landing clauses, procurement commitment execution, and the cost changes after reducing Russian oil imports (inflation and energy bills) will all affect the sustainability of the subsequent market trends.
