The Indian stock market witnessed a sharp downturn on Tuesday, May 20, as key benchmark indices plunged amid mixed global cues and domestic uncertainties. The BSE Sensex dropped 873 points, or 1.06%, to close at 81,186.44, while the NSE Nifty 50 declined 262 points, or 1.05%, ending the day at 24,683.90.
During the session, the Sensex hit an intraday low of 81,153.70 after opening slightly higher at 82,116.17, whereas the Nifty touched a low of 24,669.70 after starting at 24,996.20. The selloff wasn’t limited to large-cap stocks—the BSE Midcap and Smallcap indices also fell sharply, closing with losses of 1.65% and 0.96% respectively.
As a result of this broad-based decline, investors’ wealth eroded by over ₹6 lakh crore in a single trading session. The total market capitalisation of companies listed on the BSE dropped from nearly ₹444 lakh crore to ₹438 lakh crore.
Here are the five major reasons behind today’s market slump:
1. Uncertainty Around India-US Trade Deal
Hopes of a trade agreement between India and the United States are fading, as investors seek greater clarity on the status of negotiations. Recent reports suggest that India is discussing a deal in three tranches and aims for an interim agreement before July. However, the lack of concrete progress has kept markets on edge—especially as China and the UK have already secured trade agreements with Washington.
2. Stretched Market Valuations
India’s stock valuations are currently elevated, raising concerns among analysts. The Nifty’s price-to-earnings (PE) ratio is at 22.3—its highest in six months and slightly above the two-year average of 22.2. Such high valuations typically make investors cautious, as they suggest limited upside potential and increased vulnerability to correction.
3. US Credit Rating Downgrade
Moody’s recent downgrade of the United States’ sovereign credit rating from Aaa to Aa1 has added to global investor unease. The downgrade reflects growing debt levels and persistent political discord in the US. As the world’s largest economy shows signs of fiscal stress, global markets, including India’s, have responded negatively.
4. Lack of New Market Triggers
The Indian stock market has been moving sideways in recent sessions, largely due to the absence of fresh triggers. With tariff-related tensions and geopolitical concerns easing, investors are now waiting for the upcoming Q4 GDP data and corporate earnings to gauge the strength of the economic recovery. Additionally, the monetary policy meetings of the Reserve Bank of India and the US Federal Reserve in June are likely to shape near-term market direction.
5. Cautious Approach by Foreign Investors
Foreign Portfolio Investors (FPIs) turned net sellers on May 19, offloading Indian equities worth ₹525.95 crore in the cash segment. The selloff comes amid rising concerns over expensive valuations and weak earnings growth. Moreover, with China showing signs of economic recovery and having finalized a trade deal with the US, global investors may temporarily shift capital there, reducing short-term inflows into Indian markets.
Today’s market rout reflects a mix of domestic and global challenges that have made investors risk-averse. With uncertainties around trade talks, elevated valuations, and cautious FPI sentiment, the Indian stock market may remain volatile in the coming weeks. Market watchers will closely track macroeconomic indicators, policy decisions, and global developments to assess the future trajectory.
