Indian markets plunged sharply as Sensex fell 1,930 points and Nifty slipped below 22,500, erasing ₹13 lakh crore in market cap. Escalating Iran-US tensions, Brent crude above $113, a record weak rupee at ₹93.84 and heavy FII outflows of over ₹86,000 crore in March triggered a broad-based selloff across sectors, with global markets also under pressure.
Indian equity markets saw a sharp and broad-based selloff on Monday, March 23, 2026, as a mix of global and domestic factors dented investor confidence. The BSE Sensex dropped 1,930 points or 2.59% to 72,602.63, while the Nifty 50 fell 607.40 points or 2.63% to 22,507.10 around 12:28 pm.
The decline wiped out nearly ₹13 lakh crore in investor wealth, with the total market capitalisation of BSE-listed companies falling to ₹416 lakh crore. Selling pressure was visible across the board, with all 30 Sensex stocks trading in the red. Tata Steel, State Bank of India, HDFC Bank, Bajaj Finance, Titan and Mahindra & Mahindra were among the major losers, each declining around 2% to 3%.
Market breadth remained weak. On the NSE, 2,328 stocks declined, while only 249 advanced and 74 remained unchanged. Sector-wise, all indices traded lower, with Nifty Metal and Nifty PSU Bank indices falling more than 3%, making them the worst-performing segments.
The timing of the fall is notable, as it coincides with the sixth anniversary of March 23, 2020, when the Nifty had plunged 13% in a single session following the nationwide COVID-19 lockdown announcement. While the current situation is different, the date added to the cautious mood in the market.
The biggest trigger behind the fall remains the worsening geopolitical situation in the Middle East. The Iran–US–Israel conflict has entered its fourth week, and tensions escalated further over the weekend.
The United States issued a fresh ultimatum to Iran, warning of potential strikes on energy infrastructure if the Strait of Hormuz is not reopened within 48 hours. Iran responded by threatening to target key infrastructure across the Gulf region. With no clear path to de-escalation, uncertainty has increased sharply.
Crude oil prices surged as concerns over supply disruptions intensified. Brent crude rose to $113 per barrel. The Strait of Hormuz, which handles over 20% of global oil supply, remains at the centre of the crisis.
For India, higher crude prices translate into a rising import bill and inflation risks. This has a direct negative impact on both the currency and equity markets.
The Indian rupee weakened further, hitting a record low of ₹93.84 against the US dollar. It opened at ₹93.83, marking its weakest opening level ever. On Friday, the rupee had already fallen sharply by ₹1.2% to close at ₹93.71, its steepest single-day fall since February 2022.
Since the start of the conflict, the rupee has depreciated nearly 3%. Persistent dollar demand, rising crude prices and continued foreign outflows have kept the currency under pressure. The near-term range is seen between ₹93.00 and ₹94.25.
Foreign institutional investors have been consistent sellers in the market. They have sold equities for 16 straight sessions up to Friday, including ₹5,518 crore in the last session.
Total FII outflows for March up to March 20 stand at over ₹86,000 crore. This sustained selling has been a key factor behind the weakness in the market.
US bond yields have moved higher, reducing the relative appeal of equities. The 10-year US Treasury yield has climbed above 4.4%, its highest level in about a year, while the 2-year yield has risen to 3.93%.
Higher yields typically lead to capital moving away from emerging markets like India towards safer fixed-income assets.
The selloff was not limited to India. Global markets also came under pressure. In Asia, South Korea’s Kospi fell over 6%, Japan’s Nikkei declined more than 4% and Hong Kong’s Hang Seng dropped 3.5%.
US markets had already closed lower on Friday, with the Nasdaq down more than 2% and the S&P 500 falling over 1.5%. European markets also ended in the red, with Germany’s DAX and France’s CAC falling around 2%, and the UK’s FTSE down nearly 1.5%.
State-run oil marketing companies increased industrial diesel prices by 25%, or around ₹22 per litre. While retail prices remain unchanged, the hike is expected to raise costs for sectors such as railways, transport, mining, infrastructure, manufacturing and telecom.
Industrial diesel accounts for roughly 13% of total diesel consumption in the country, making the increase significant for many businesses.
Despite the geopolitical tensions, gold prices have not seen a strong rally. The main reason is the strength of the US dollar, which is currently acting as the preferred safe-haven asset, limiting gains in gold.
With the conflict showing no signs of easing and crude oil prices staying elevated, market volatility is likely to continue. Currency weakness and global risk aversion remain key concerns.
At the same time, some sectors may see relative resilience. Export-oriented segments such as pharmaceuticals, automobiles and auto ancillaries could benefit from the weaker rupee. The IT sector, which has seen recent pressure, may also see some recovery if global cues stabilise.
For now, markets are expected to remain driven by geopolitical developments, crude oil prices and currency movements.
