World growth will be 3.1% in 2026, according to the International Monetary Fund October 2026 World Economic Outlook, released on 13 October. World growth is expected to slow from 3.5% in 2025, with global output above $128 trillion in current United States dollars. Headline inflation is forecast at 4.7% for 2026, driven mainly by higher energy and food prices, before easing in later years as energy costs settle.
The United States is the largest economy at $32.6 trillion, followed by China at $21.5 trillion, Germany at $5.47 trillion, Japan at $4.34 trillion, the United Kingdom at $4.27 trillion and India at $4.06 trillion. The IMF expects United States growth of 2.3% in both 2026 and 2027, China growth of 4.5% in 2026 and 4.0% in 2027, and India growth of 7.0% in both years. Japan is the slowest among large economies at 0.7%, while the euro area is expected to grow by 1.1% in 2026.

The outlook, titled Resilience Under Pressure, Urgent Choices, cautions that forecasts carry large uncertainty. Energy prices, trade friction and the pace of investment in artificial intelligence all affect the outcome. The Fund expects global growth to rise to 3.4% in 2027, supported in part by strong investment linked to artificial intelligence, but it cautions that higher energy prices could hold back households and firms in energy-importing economies.
On a purchasing power basis, China output is put at $44.6 trillion in international dollars, about 36% larger than the United States, while India moves to third at $19.2 trillion, nearly three times Germany. The IMF notes that purchasing power figures are useful for comparing living standards, while market exchange rates matter more for trade and finance. Per person, India output in 2025 was $2,670, against Japan $36,119, less than one-thirteenth of Japan figure, showing how averages hide wide differences in living standards.
For the United Kingdom, the IMF forecast puts growth at 1.3% in 2026, ahead of the euro area, with the United Kingdom remaining the fifth largest economy in 2026 at $4.27 trillion. In 2027, India is projected to overtake both Japan and the United Kingdom, reaching $4.52 trillion, while the United Kingdom reaches $4.49 trillion and Japan $4.47 trillion. That shift reflects faster growth in India and the effect of exchange rates on dollar measures of output.
