India has officially surpassed Japan to become the world’s fourth-largest economy in 2025, a milestone confirmed by NITI Aayog CEO B V R Subrahmanyam.
According to the IMF's April 2025 report, India’s GDP reached
$4.19 trillion, marking rapid economic growth and increasing global influence.
Japan, previously the fourth-largest economy, now ranks fifth with a GDP of
$4.19 trillion despite a robust growth rate of
6.5%.
This shift highlights India’s accelerating economic momentum amid global economic realignments.
"India has become the fourth largest economy in the world, overtaking Japan," Subrahmanyam said.
The milestone reflects India’s expanding market size, investment inflows, and structural reforms driving growth.
The overtaking of Japan, a long-standing economic powerhouse, underscores India’s rising stature on the global stage and its potential to influence international economic policies.
As India continues to grow, this new ranking is expected to attract further foreign investment and strengthen its geopolitical influence.
The economic data from IMF and statements from Indian officials confirm a significant shift in the global economic hierarchy, with India emerging as a key player in the coming decades.
