What happened to Indian markets today?
The selloff was broad-based. The BSE 150 Midcap index fell 2.51% and the BSE 250 Smallcap index declined 2.57%.
Across the two sessions, markets shed the following:
Sensex: down 3,326 points, or 4.42%
Nifty 50: down 975 points, or 4.18%
BSE total market cap: fell from ₹431 lakh crore to below ₹413 lakh crore
Investors lost more than ₹18 lakh crore in wealth across both sessions.
Why did the Sensex fall? Six reasons
1. US-Iran war enters fifth week
The US-Iran conflict, which began on 28 February 2026, has entered its fifth week with no resolution in sight. The Trump administration sent a 15-point ceasefire proposal to Iran, but no formal talks have taken place. Communication between the two sides has been limited to back channels and intermediaries, including Pakistan’s efforts to mediate.
Yemen-based Houthis, backed by Iran, have joined the conflict and said they will continue operations until US and Israeli strikes on Iran and allied groups cease, according to Bloomberg. The deployment of additional US troops to the region signals escalation rather than de-escalation.
2. Crude prices surge above $115
Brent Crude climbed above $115 per barrel as the Strait of Hormuz, through which approximately 20% of global crude oil and LNG flows, remained effectively closed to most shipping.
India is the world’s third-largest crude oil importer and meets 85 to 90% of its oil needs through imports. Analysts have warned that India’s pre-war macroeconomic position, marked by strong GDP growth, low inflation, and manageable fiscal and current account deficits, faces significant pressure if crude prices remain elevated.
3. India VIX spikes to 28
India VIX, the market’s volatility gauge, jumped 4% to 28. Its normal range is 12 to 15. A reading above 15 indicates markets expect elevated volatility over the next 30 days. A reading of 28 reflects significant investor nervousness around the persistence of the West Asia conflict and its potential to disrupt energy supplies and global growth.
4. FPIs pull ₹1.23 lakh crore in March
Foreign portfolio investors withdrew ₹1,23,025 crore from Indian financial markets in March through 27 March, according to NSDL data.
FPI equity holdings fell by $79 billion to $710 billion in the fortnight to 15 March, the steepest fortnightly decline in at least six years, exceeding the COVID-19 pandemic-era selloff.
5. Rupee hits record low of 95.23
The Indian rupee fell 42 paise during the session to a record low of 95.2350 against the US dollar, according to Bloomberg data. A weaker rupee accelerates foreign capital outflows and amplifies broader market pressure.
6. March F&O expiry
Monday marked the expiry of the March futures and options series. Tuesday, 31 March, is a market holiday on account of Shri Mahavir Jayanti. F&O expiry sessions typically see elevated volatility as traders close or roll over positions to the April series.
Outlook
With the US-Iran conflict in its fifth week and Brent Crude above $115, analysts have flagged the prospect of lower GDP growth, higher inflation, and wider fiscal and current account deficits in FY27. No formal ceasefire talks are scheduled as of 30 March 2026.
