South Korea Overtakes India as 6th Largest Stock Market, UK Reclaims 5th Largest Economy | First Time in History


New Delhi/Mumbai: In a double blow to India's global standing, the country has been overtaken on two critical economic fronts. South Korea has surged past India to become the world's sixth-largest stock market, while the United Kingdom has reclaimed its position as the fifth-largest economy, pushing India down to sixth place .
South Korea Surges in Market Cap
On June 2, 2026, South Korea's combined market capitalization — encompassing the KOSPI, KOSDAQ, and KONEX exchanges — rose to approximately $5.01 trillion*, surpassing India's National Stock Exchange valuation of *$4.85 trillion . This marks the first time South Korea has ranked above India in equity market size.
The dramatic shift has been driven by a massive rally in AI semiconductor stocks. Samsung Electronics and SK Hynix have each surpassed a market capitalization of $1 trillion this year, propelling South Korea's total market value up by an extraordinary 86% in 2026 alone . In contrast, India's market capitalization has contracted by about 9% over the same period .
Just last month, Taiwan had overtaken India to claim the fifth spot, and now South Korea's ascent has pushed India further down to seventh place globally .
Why India Has Fallen Behind
The decline in Indian equities reflects a perfect storm of headwinds:
Foreign investor exodus: Overseas investors have pulled out a record *$26.4 billion* from Indian stocks so far in 2026, surpassing the previous annual record of $18.91 billion set in 2025 .
Weak market performance: The Nifty 50 and BSE Sensex have lost 10.1% and 12.5% respectively this year .
Limited AI exposure: Unlike South Korea's chip-heavy market, India lacks significant exposure to the AI-driven tech rally that has lifted global markets .
UK Overtakes India in GDP Rankings
On the economic front, the International Monetary Fund's April 2026 World Economic Outlook has confirmed that the United Kingdom has overtaken India to become the world's fifth-largest economy by nominal GDP .
The current rankings stand as follows:
Rank Country Nominal GDP (2026)
1 United States $32.38 trillion
2 China $20.85 trillion
3 Germany $4.90 trillion
4 Japan $4.38 trillion
5 United Kingdom $4.26 trillion
6 India $4.15 trillion
Why India Lost Its Spot
Paradoxically, India's slide in the rankings has nothing to do with weak economic growth. India continues to be one of the world's fastest-growing major economies, with a projected real GDP growth of approximately 7.6% for FY2026 . The culprit is the sharp depreciation of the Indian rupee.
The rupee has weakened by nearly 10% against the US dollar over the past year, falling to historic lows around 95 per dollar amid the US-Iran conflict and soaring crude oil prices . Since global GDP rankings are calculated in dollar terms, this currency depreciation has significantly reduced the dollar value of India's economic output — by an estimated $400 billion .
As India Infoline notes, "India can continue to grow domestically while slipping in global dollar-based rankings" . This situation highlights the vulnerability of import-dependent economies like India to external shocks.
Looking Ahead
Despite these setbacks, economists remain optimistic about India's medium-term trajectory. Current projections suggest India could regain lost ground and potentially move back to fourth place by 2027, overtaking both the UK and Japan again . On a Purchasing Power Parity (PPP) basis, India remains the world's third-largest economy, behind only the US and China, reflecting its genuine domestic economic strength .
The current ranking shift serves as a reminder that currency movements — not just growth fundamentals — can dramatically alter a country's perceived economic standing on the global stage.
