World Ranking of Economies · A Colaeb Annual Report
The world economy reached US$118.35 trillion
The inaugural World Ranking of Economies ranks 196 economies by 2025 GDP in current U.S. dollars. World output reached US$118.35 trillion, and the United States alone produced 26.00% of it. The UK edged back past India into 5th place, US$4.00 trillion to US$3.96 trillion, despite India's faster real growth; the IMF projects India will pass both the UK and Japan in 2027. Swiss and Polish GDP crossed US$1 trillion, taking the trillion-dollar club to 21, while the edition's biggest rank moves, led by Ghana up 10 and Venezuela down 12, were driven mainly by exchange rates and prices rather than output.
The world economy reached US$118.35 trillion
World GDP in 2025 came to US$118.35 trillion in current U.S. dollars. Measured across the economies with data for both years, dollar GDP rose 6.0% on 2024. (World total is the World Bank's world aggregate.)
The U.S. alone is 26.00% of world output
At US$30.77 trillion, the United States produced 26.00% of world GDP. Add China and the two account for 42.47%. The U.S. economy is 1.58 times the size of China's.
The UK retook fifth place from India, narrowly
The UK's US$4.00 trillion edged out India's US$3.96 trillion, even though India's real growth (+7.6%) outpaced the UK's (+1.4%). Both the World Bank and IMF figures put the UK ahead for 2025.
India passes Japan and the UK in 2027, the IMF projects
In the IMF's October 2026 forecasts, India reaches US$4.52 trillion in 2027, ahead of the UK (US$4.49 trillion) and Japan (US$4.47 trillion), making it the 4th-largest economy that year. In 2025, Japan was 4th and India 6th.
The trillion-dollar club grew to 21
21 economies topped US$1 trillion in 2025, up from 19 in 2024. The newcomers: Switzerland (US$1.04 trillion) and Poland (US$1.04 trillion).
Currency, not output, drove the biggest climb
Ghana rose 10 places to 71st, the biggest climb in this edition. Its dollar GDP jumped 37.1% while real output grew 6.0%: most of the gain came from exchange-rate and price effects.
Fast growth, falling rank
Ethiopia's real economy grew 9.8%, the 6th-fastest rate in the world, yet it fell 7 places to 68th as its GDP measured in dollars dropped 15.6%.
Ten economies hold 66.3% of world output
The top 10 produced 66.3% of world GDP. The smallest 100 economies together produced 1.42%.
China's economy is 15.9 times its 2000 size
China grew from US$1.22 trillion in 2000 to US$19.50 trillion in 2025 in current dollars, and from 6th in the world to 2nd.
Per person, a 936-fold gap
GDP per person ranged from US$218,978 in Liechtenstein to US$234 in Burundi, a gap of 936 times.
