The World Economy in 2040: Three Powers, Half of Global GDP
The world economy in 2040 will be larger, more Asian and more concentrated than today’s. Projections from the Centre for Economics and Business Research (Cebr) put global output at $227 trillion in 2040, up from about $124 trillion in 2026, an increase of 83 percent in nominal dollar terms. Three countries account for just over half of that total: the United States at $52.9 trillion, China at $47.9 trillion and India at $14.1 trillion.
The headline most readers expect is missing. China does not overtake the United States in any year through 2040. The gap narrows from $10.7 trillion in 2026 to about $5 trillion, but America keeps first place. For boards setting 15-year strategies, the planning question is no longer when the lead passes to China. It is how a two-superpower economy, with India as a fast-growing third pole, will reshape demand, supply chains and capital allocation.
The world economy in 2040 rests on a three-power core
Cebr’s World Economic League Table, published in December 2025 and covering 190 economies, measures GDP in current US dollars without inflation adjustment. On that basis, the United States holds about 26 percent of world output in 2026 and 23 percent in 2040. China’s share rises from 17 percent to 21 percent. India’s reaches 6.2 percent.
Together the three produce 50.6 percent of global GDP in 2040. No other economy exceeds 3.5 percent. Germany, fourth at $7.8 trillion, is little more than half India’s size. The rest of the top 20 sits in a dense middle band between $2 trillion and $7 trillion, where a single exchange-rate swing can move a country several places.
The implied growth rates explain the shape. Over the 14 years from 2026 to 2040, the projections imply nominal dollar growth of roughly 3.7 percent a year for the United States, 6.1 percent for China and 8.5 percent for India, against about 4.4 percent for the world as a whole.
The receding crossover: why China narrows the gap but never closes it
CEOWORLD Magazine calls this pattern the receding crossover: a forecast date for China overtaking America that moves further out each time it is revised, until it drops off the horizon. Cebr’s own league table, published in December 2020, projected that China would become the world’s largest economy in 2028. Five editions later, the crossover does not occur at all before 2040.
Several forces account for most of the revision. China’s population is shrinking and ageing, which caps the labor force. Its property sector, once a major engine of investment, has contracted. And because the table measures output in dollars, years of weak domestic prices and a softer renminbi reduce China’s dollar GDP even when real activity grows.
By a different yardstick, the race is already over. Adjusted for purchasing power parity, which accounts for lower prices in China, the International Monetary Fund ranks China as the world’s largest economy in 2026. The two measures answer different questions. PPP better captures domestic production and living standards; dollar GDP better captures what an economy can buy abroad, the size of its market for multinational companies and its weight in global finance. For a CFO pricing a market entry or a central bank sizing reserves, the dollar figure is usually the relevant one.

India and Indonesia climb as Germany and Japan slip
India is the largest mover among major economies. Cebr places it fourth in 2026, having passed Japan, and third by 2030, a position it holds through 2040. Its economy more than triples over the period, from $4.5 trillion to $14.1 trillion, exceeding the combined 2040 output of Germany ($7.8 trillion) and Japan ($5.9 trillion).
Cebr ties Asia’s rise to demographics: younger populations in South and Southeast Asia provide a labor force that Europe and Japan, and now China, are losing. Scale and income remain different things, though. Divided across roughly 1.6 billion people, India’s projected 2040 output works out to under $9,000 a head, far below every other top-five economy. India in 2040 will be a vast market with a relatively low average income, and companies that price for the average will miss most of it.
Indonesia makes the largest jump in the top 10. It climbs from sixteenth in 2026 to eighth in 2040, and its projected $4.2 trillion economy overtakes Italy’s $3.8 trillion, pushing Italy out of the top 10. Brazil and Canada hold ninth and tenth.
Germany and Japan both keep growing in dollar terms but lose rank. Germany falls from third to fourth as India passes it. Japan slips from fifth to sixth, overtaken by the United Kingdom, which holds fifth from 2030.
Asia’s rising share and the capital allocation question
Cebr projects Asia’s share of world GDP rising from 35.6 percent in 2025 to 42.1 percent by 2040, while Europe’s falls to about 20.5 percent. Within that shift, the composition matters as much as the total. China’s contribution grows mainly through industrial upgrading; India’s and Indonesia’s grow through population and urbanization. The first creates competition for Western manufacturers. The second creates consumer and infrastructure demand.
For investors, the difference shows up in where returns accrue. A rising share of world GDP does not guarantee a rising share of listed corporate profits, because many of the fastest-growing economies have shallow equity markets, large state sectors or capital controls. The opportunity in India and Indonesia is real, but much of it will be captured through direct investment, private markets and local partnerships, with index weights a poor guide to exposure.
What nominal projections leave out
Any 15-year forecast in current dollars carries large exchange-rate risk. A sustained 10 percent move in the dollar against a basket of currencies would reshuffle much of the middle of the table, where Canada, Italy, Spain, South Korea, Australia, Mexico and Russia are separated by about $570 billion. The ranking is best read as a central scenario, not a destination.
The projections also predate the full effect of US tariff policy. Cebr notes that global growth slowed for a fourth straight year in 2025, to an estimated 2.6 percent, and expects a further slowdown in 2026 as tariffs work through the economy. How trade rerouting settles, and which economies gain from supply chains moving out of China, is the largest single uncertainty in the medium-term order.
Executive takeaways
- What changed. The long-expected moment when China overtakes the United States in dollar GDP no longer appears in Cebr’s 2040 horizon, while India is projected to become the third-largest economy by 2030.
- Why it matters. Global strategy now has to plan for two economies of similar size that operate under different rules, plus a third pole whose market is large but low-income. Europe and Japan lose relative weight in global demand.
- What leaders should do next. Stress-test 2030 and 2040 plans against both dollar and PPP measures, including exchange-rate scenarios for mid-table markets. Size India and Indonesia by income segment, not headline GDP.
The principal uncertainty over the next 12 to 24 months is trade. If tariffs push a lasting share of manufacturing out of China, India and Southeast Asia could reach these projections early; if the shift stalls, Asia’s rise will depend more heavily on China alone. Executives should watch foreign direct investment into India and Indonesia, along with China’s price level and the dollar’s trade-weighted value. Together these will decide whether the 2040 table is a forecast or a ceiling.
Key insights and takeaways
- The world economy is projected to grow from about $124 trillion in 2026 to $227 trillion by 2040, an 83 percent rise in nominal dollars, on Cebr’s World Economic League Table projections.
- The United States, China and India are projected to produce 50.6 percent of global GDP in 2040, with the US at $52.9 trillion, China at $47.9 trillion and India at $14.1 trillion.
- China does not overtake the United States in Cebr’s dollar-based projections through 2040, although the gap narrows from $10.7 trillion in 2026 to about $5 trillion.
- India is projected to become the world’s third-largest economy by 2030, passing Germany, and to exceed the combined output of Germany and Japan by 2040.
- Indonesia is projected to climb from sixteenth in 2026 to eighth in 2040, with a $4.2 trillion economy that pushes Italy out of the global top 10.
