Indian Markets Plunge as US Yields and Oil Prices Surge

Indian equity markets experienced extreme volatility between September 15 and 16, 2026, characterized by an early rally followed by a sharp crash. On Tuesday, the BSE Sensex and NSE Nifty initially opened higher, driven by a surge in information technology stocks including HCL Technologies and Infosys. This early recovery briefly ended a five-day losing streak, with the Sensex climbing over 500 points in early trade.

However, the market reversed course sharply, with the Sensex plunging 778 points to close at 74,003.82, a three-month low. The Nifty dropped to 23,118.60, its lowest level in five months, wiping out approximately ₹9 lakh crore in market capitalization. Analysts attributed the crash to a combination of US 10-year Treasury yields crossing 5%, Brent crude oil rising above $108 per barrel following attacks on Saudi Arabian energy infrastructure, and investor anxiety over a potential interest rate hike by the Federal Reserve System.

While most sectors declined, IT stocks remained resilient as calls for a slower pace of AI development from industry leaders eased fears of rapid service disruption. By Wednesday morning, the markets saw a modest rebound driven by value buying, with the Sensex rising 244.02 points. Despite this recovery, analysts warn that the Federal Reserve's guidance on future tightening remains the primary trigger for market direction, as a hawkish tone could further pressure the Indian rupee and global equities.
