The International Monetary Fund projects in its October outlook that Japan’s nominal GDP in 2027 will be overtaken by both India and the United Kingdom, dropping Japan to sixth place. A weak yen is seen as the key factor speeding the slide.
According to Seoul Economic Daily’s English edition and The Japan Times, the IMF’s October World Economic Outlook, released on October 14, estimates Japan’s 2027 nominal GDP at $4.4676 trillion. India is put at $4.5211 trillion in fourth place and the UK at $4.4889 trillion in fifth. Seoul Economic Daily said it would be the first time since 1968 that Japan ranks sixth.

Even for this year, the figures are $4.3419 trillion for Japan and $4.0602 trillion for India, so the gap is closing fast.
Japan passed West Germany in 1968 to become the second-largest economy, ceded second place to China in 2010 and lost third place to Germany in 2024. Seoul Economic Daily noted that over the past two decades Japan’s nominal GDP grew 1.2% while Germany’s grew 95.2%, turning Japan from more than twice Germany’s size to smaller than it. The new projection suggests the trend continues.
Exchange rates matter a great deal here. Nominal GDP is converted into dollars, so when the yen keeps weakening against the dollar, the dollar size of the economy shrinks even if real output grows. Seoul Economic Daily said the yen’s continued weakness has weighed on Japan’s dollar-based ranking. The reports we reviewed gave no specific inflation figures, so we do not draw conclusions on prices.
Real growth forecasts also contrast. The IMF projects 2026 growth of 0.7% for Japan, 7% for India (revised up), 1.3% for the UK (raised) and 3.3% for South Korea (revised up on semiconductor and AI exports). Global growth is put at 3.1%, 0.1 percentage point above July, as AI demand offset the effect of higher energy prices.
Still, nominal GDP rankings are sensitive to currency and price moves and are not the same as per-person income, which better reflects living standards. India’s rise also reflects structural growth from its large population. The projection is only an IMF estimate, and rankings could shift if exchange rates change. It also carries lessons for other Asian economies that compete with Japan.
