India stocks tumble as Iran tensions, US tariffs drive oil higher
India's benchmark indices fell over 1% as escalating US-Iran tensions pushed Brent crude above $92 and new American tariff threats compounded the risk of foreign capital outflows.
Indian equities suffered a broad selloff on Wednesday, with the Nifty 50 breaching a key support level of 24,000 to hit an intraday low of 23,961.40. The Sensex plummeted more than 800 points to 76,641.19, while mid- and small-cap indices underperformed with losses of up to 1.5%. The declines reflect a rapid shift in risk appetite as external headwinds mount for the import-dependent economy.
The immediate catalyst for the risk-off move is the widening US-Iran conflict, which has driven oil prices to their highest levels in over a month. Iran launched a large drone attack on what it described as US ammunition facilities in Kuwait, while the US military conducted an 11th night of strikes and threatened action near Iran's primary nuclear enrichment facilities. Brent crude surged to $92.67 a barrel, a level not seen since June 11.
For India, a major oil importer, the crude spike threatens to inflate the import bill and complicate the domestic inflation outlook. The Indian rupee weakened by 11 paise to 96.36 against the dollar in early trade. "The continuing U.S.-Iran conflict and rising Brent crude price will continue to weigh on markets despite positive news on other fronts," said VK Vijayakumar, Chief Investment Strategist at Geojit Investments.
Tariff shock to pharma sector
Renewed US protectionism also targeted one of India's most significant export sectors. President Donald Trump announced a phased tariff regime on generic drugs, while USTR Jamieson Greer indicated broader measures targeting dozens of countries are imminent. "Effective August 1st, 2026, all Generic Drugs being brought into the United States will continue to have a TARIFF of ZERO PERCENT for a two-year period of time, after which the TARIFF will be raised to 100% for a one-year period of time, and 200% thereafter," Trump said.
These overlapping pressures are aligning with a stronger US dollar and rising Treasury yields, raising the probability of sustained foreign capital outflows from emerging markets. The dollar index sits above 101, and the US 10-year yield has climbed to 4.635% in just four sessions. "Technically, the rupee is expected to trade in the 96–96.45 range in the near term," said Jateen Trivedi, VP Research Analyst at LKP Securities, adding that focus will now shift to the Federal Reserve's July 29 policy decision for direction.
