WTO Scenarios Split Global Exports by 44.8 Points by 2050
A strengthened multilateral trading system would raise global GDP by 2.9 percent and global exports by 17.9 percent by 2050 against the baseline, the World Trade Organization said on 15 September in its World Trade Report 2026. A world where multilateral rules are replaced by a network of free trade agreements would cut GDP by 6.9 percent and exports by 26.9 percent. A world organised into geopolitical blocs would cut GDP by 5.1 percent and exports by 18.6 percent.
The distance between the best and worst of those three is 9.8 percentage points on the 2050 GDP path and 44.8 percentage points on the 2050 export path, both measured against the baseline, on our calculation. The organisation itself frames the gap as an opportunity cost of roughly 5 to 10 percent of global real GDP.
Trade moves several times as far as output
In each scenario the export number is a multiple of the GDP number: roughly 6 times in the strengthened case, and roughly 4 times in each of the two erosion cases, on our calculation. The organisation publishes each figure to one decimal, so the multiples cannot be stated more precisely. That ratio is the report’s most useful single property for a trading economy: whatever happens to world output under these scenarios, trade volumes move roughly four to six times as far.
| Scenario | GDP by 2050 | Exports by 2050 |
|---|---|---|
| Strengthened multilateral system | 2.9% | 17.9% |
| Geo-fragmented world | -5.1% | -18.6% |
| Free trade agreement world | -6.9% | -26.9% |
World Trade Report 2026, A Critical Juncture for the World Trading System, issued by the WTO Secretariat on 15 September 2026. Changes are against the baseline trajectory to 2050. The headline 3 percent and 3 trillion dollars quoted by the organisation correspond to the 2.9 percent shown.
Who gains is not who gains most
The gains divide in two directions at once. High income economies take about 1.7 trillion dollars in 2023 dollars, more than half of the roughly 3 trillion the organisation attaches to the upside, on our calculation. Both figures are the organisation’s own approximations, so the share cannot be put more precisely. Least developed countries take the largest proportional gain, 7.7 percent of GDP, more than 2.5 times the 2.9 percent global figure, on our calculation, from a group that currently accounts for less than 1 percent of world trade.
The system the report defends still governs most trade. Around 72 percent of global merchandise trade takes place under most favoured nation terms, Director-General Ngozi Okonjo-Iweala said, and the system has supported an almost 50 fold expansion in global trade across 8 decades.
Why it matters: In all three scenarios global trade moves substantially more than global output, which makes the direction of the trading system more consequential for trade exposed economies, including re-export hubs and energy exporters, than the headline output figures suggest on their own. The organisation does not estimate an equivalent multiplier for any individual country.
Outlook: The report presents scenarios to 2050 and no forecast for any year before that. It was launched on the first day of the organisation’s Public Forum on 15 September in Geneva.
