India Overtakes Japan as World's Fourth-Largest Economy

Milestone Driven by Growth Gap and Yen Weakness

India's nominal gross domestic product reached approximately $4.27 trillion in calendar year 2025, surpassing Japan's $4.19 trillion to make India the world's fourth-largest economy behind the United States ($28.8 trillion), China ($18.5 trillion), and Germany ($4.46 trillion). The milestone, confirmed by IMF data released on February 27, was accelerated by the yen's persistent weakness, which reduced Japan's dollar-denominated GDP.

India's economy grew 6.8% in real terms during its fiscal year ending March 2026, while Japan grew just 1.2%. The yen's 15% depreciation against the dollar between January 2024 and December 2025 widened the gap in nominal dollar terms.

Structural Drivers of India's Rise

India's economic ascent reflects several structural advantages: a population of 1.44 billion (the world's largest since 2023), a median age of 28 years, and an expanding services sector that accounts for 55% of GDP. The country's digital infrastructure — including the Unified Payments Interface, Aadhaar biometric system, and Open Network for Digital Commerce — has created efficiencies that accelerate formalization and financial inclusion.

"India's growth trajectory is supported by favorable demographics and a rising investment rate," said Raghuram Rajan, former RBI governor and professor at the University of Chicago. "But per-capita income remains low at roughly $3,000, and the quality of growth — in terms of employment generation and inclusion — needs attention."

Japan's Relative Decline

Japan's nominal GDP in dollar terms has fallen from $6.3 trillion at its peak in 2012 to $4.19 trillion, largely due to the yen's depreciation from approximately 80 per dollar to 148. In yen terms, Japan's nominal GDP has grown modestly, but persistent deflation and low population growth have constrained expansion.

Japan remains significantly wealthier on a per-capita basis, with GDP per capita of approximately $33,800 compared to India's $2,960. Japan also holds a commanding lead in human development indicators, infrastructure quality, and technological sophistication.

India's Path to Third

The IMF projects that India will overtake Germany to become the world's third-largest economy by 2028 if current growth differentials persist. India's GDP is growing at approximately $300 billion per year in nominal terms, while Germany's has stagnated in dollar terms due to economic headwinds in its manufacturing sector.

Finance Minister Nirmala Sitharaman said the milestone reflected "the fruits of structural reforms" including the goods and services tax, insolvency code, and production-linked incentive schemes. She set a target of making India a $7 trillion economy by 2030.

Challenges Ahead

India's growth faces several headwinds. Youth unemployment remains elevated at approximately 15% for ages 15-29. Manufacturing's share of GDP has stagnated at about 17%, below the 25% target. Infrastructure deficiencies, regulatory complexity, and land acquisition challenges continue to constrain industrial expansion.

The government's fiscal deficit of 5.1% of GDP limits the scope for public investment, and the Reserve Bank of India must balance growth support with inflation management and currency stability.

Market Implications

India's weight in the MSCI Emerging Markets Index has risen to 19.5%, approaching China's 26%, and is expected to surpass it by 2028 if current trends continue. Foreign institutional ownership of Indian equities has declined from 22% to 16% over the past three years as domestic mutual funds have absorbed a growing share of market capitalization, which now stands at approximately $4.8 trillion.
