Sensex, Nifty Fell | Why Did Indian Stock Market Plunge Today? Trump Tariffs | Recession Fears Loom US President Donald Trump's tariffs have unleashed chaos across the globe, wiping out trillions of dollars worldwide and plunging the Indian equity markets to their 10-month low. Sensex opened nearly 4,000 points lower, sliding over 3.5% since its last trading session, while Nifty tanked over 1,000 points this morning. The crash follows a massive sell-off in Asian equities, panicked by Trump's radical policies, and US futures pointing at significant losses when it resumes trading this evening.
