India's stock market reclaims $5 trillion valuation; what’s driving the rally?

Driven by a sustained rally, India's stock market has reclaimed the $5 trillion valuation milestone, adding nearly $290 billion in investor wealth over the past four trading sessions.

The landmark achievement comes as global markets reassess risk following a peace agreement between the US and Iran, easing concerns over a prolonged conflict in West Asia. For India, one of the world's largest crude oil importers, the development has been particularly beneficial.

The latest surge has propelled the combined market capitalisation of all BSE-listed companies to $5.01 trillion (around ₹474 lakh crore), a level last seen on May 8.

The BSE Sensex has rallied 3,250 points in four sessions, while the NSE Nifty has added over 900 points during the same period. At the time of reporting, the Nifty50 was up 59.30 points at 24,045, and the Sensex was trading 245 points higher at 77,054 level.

The rally has been driven by a sharp correction in crude oil prices, which is expected to reduce pressure on inflation, improve fiscal dynamics and support corporate profitability.

Investor sentiment has also been aided by a steep decline in market volatility. India VIX, often referred to as the market's fear gauge, has fallen more than 15% over the past week to around 13.3, signalling a significant easing in risk perception as geopolitical tensions moderate.

BSE m-cap rises 6% in four sessions

Over the last four trading sessions, the aggregate market capitalisation of BSE-listed firms has risen by more than 6%. Since the beginning of April, the value of listed companies has expanded by nearly 14%, highlighting the strength and breadth of the ongoing rally.

Notably, the gains have been driven more by the broader market than by benchmark heavyweights. While the Sensex has advanced around 7% since April, the BSE MidCap, SmallCap and MicroCap indices have delivered substantially stronger returns, reflecting increased investor confidence in domestic growth-oriented businesses and continued participation from retail investors.

Despite crossing the $5 trillion mark again, India's equity market remains below its historic peak. The total market capitalisation is still about 13 % lower than the record high of roughly $5.7 trillion reached in September 2024 and remains modestly below levels seen at the beginning of 2026.

Globally, India continues to rank among the world's largest equity markets, although its position has slipped in recent months. The US remains the dominant market by a wide margin, followed by China and Japan. Meanwhile, Taiwan and South Korea have strengthened their standing, buoyed by a powerful rally in semiconductor and artificial intelligence-linked stocks.

India's relative ranking has also been impacted by foreign capital flows and currency movements. During the first five months of 2026, foreign institutional investors (FIIs) were significant net sellers of Indian equities, withdrawing around $27.5 billion. However, strong domestic participation helped absorb the selling pressure, with domestic institutional investors (DIIs) investing nearly $50 billion during the same period.
