India is on course to become the world's fourth-largest economy by 2027, surpassing Japan in nominal GDP terms, according to projections cited in an IMF report. At that point, India's economy is expected to be valued at approximately $4.5 trillion, pushing Japan down to sixth place — behind both India and the United Kingdom.

India's Growth Trajectory

The IMF's forecasts highlight a sharp divergence in economic momentum between Asia's two major democracies. India's GDP growth is projected at 7 per cent in 2026, reflecting sustained resilience even as geopolitical tensions and global energy price shocks weigh on many other economies. Japan, by contrast, is expected to expand by a modest 0.7 per cent in the same year.

Speaking at the release of the IMF's Asia-Pacific regional economic outlook earlier in October, a senior IMF official noted that India entered the recent surge in global energy prices from a position of strength, supported by solid growth, fiscal discipline, and substantial foreign exchange reserves. According to the IMF, these macroeconomic fundamentals have allowed India to absorb higher energy costs more effectively than most peer economies.

Japan's Structural Headwinds

Japan continues to face a cluster of deep-seated structural challenges. An ageing population, weak domestic demand, and sluggish long-term growth have persistently capped its economic expansion. Consumer prices in Japan have been rising steadily since 2022, and recent geopolitical developments have compounded inflationary pressures through elevated fuel and energy costs.

The yen's sharp depreciation — hitting its lowest level in 40 years against the US dollar over the summer — has further inflated import costs, squeezing households and businesses alike, according to the analysis. Japan's shrinking working-age population adds another structural drag that monetary or fiscal policy cannot easily offset.

What the Rankings Shift Means

Japan currently holds the fourth position in global GDP rankings and is expected to retain it through 2026. However, the IMF's trajectory points to India crossing ahead in 2027. This would make India the third Asian economy — after China and Japan currently — to rank among the world's top five, and would cement its status as the fastest-growing major economy globally.

Notably, India only overtook the United Kingdom to become the world's fifth-largest economy in 2022, having earlier displaced France. The projected leap past Japan would represent another milestone in a rapid, decade-long ascent up the global rankings.

Outlook and Caveats

While the IMF projections are broadly optimistic for India, analysts caution that nominal GDP comparisons are sensitive to currency fluctuations. A significant strengthening of the yen or a sharper-than-expected slowdown in Indian growth — whether from a global recession, domestic demand softness, or geopolitical disruption — could alter the timeline. Sustained execution on fiscal consolidation and infrastructure investment will be critical to India maintaining its growth premium over the coming years.
