MUMBAI — The Bombay Stock Exchange's benchmark Sensex index crossed 100,000 points for the first time in July 2026, a milestone celebrated with diyas and sweets on the trading floor of the 150-year-old exchange on Dalal Street. The moment carried symbolic weight beyond the numbers: the Sensex has delivered total returns of approximately 180% over the past five years, making India the best-performing major equity market in the world over that period.

Analysts point to three structural forces driving the rally. First is demographics: India has a median age of 28, a rapidly expanding middle class projected to reach 500 million by 2030, and a workforce growing at 1.5% annually at a time when most major economies face demographic decline. Second is digital infrastructure: the India Stack — a suite of government-backed digital identity, payment, and data-sharing platforms — has enabled a fintech revolution that has brought 400 million Indians into the formal financial system, many of whom are investing in equities for the first time. Monthly SIP (systematic investment plan) flows into mutual funds have reached $3.5 billion, providing a steady domestic bid for equities. Third is a manufacturing renaissance driven by government production-linked incentive schemes that have attracted $50 billion in electronics manufacturing alone.

"We are in the early stages of what could be a multi-decade compounding story," said Ridham Desai, Morgan Stanley's head of India equity strategy. "The question isn't whether India will be the world's third-largest economy — it's whether the capital markets are priced for a future that's arriving faster than anyone expected."
