India Passes Japan to Claim 4th-Largest Economy at $4.18 Trillion

Powerhouses shuffle rank roughly once a generation: Japan displaced West Germany in 1968, China vaulted past Japan in 2010, and now India edges Japan in 2025. Each leap has accompanied a demographic surge, export-led or consumption-led growth, and a re-wiring of global supply chains. India’s ascent reflects longer-term currents—urbanisation, digital public infrastructure, and a pivot of multinationals diversifying away from China—yet it also spotlights persistent per-capita gaps reminiscent of China’s position when it overtook Japan (GDP per head barely 1⁄10th of Japan’s in 2010). Over a century horizon, this milestone matters less for the bragging rights than for confirming that economic gravity keeps drifting toward the populous South and that late-industrialisers can still climb the ladder—provided they convert scale into broad-based productivity and jobs before the demographic window narrows in the 2040s.
