The World Trade Organization projects that a breakdown of multilateral trade rules could cost the global economy 5–10% of real GDP by 2050. The estimate appears in the WTO's 2026 World Trade Report, released September 15 at the Public Forum in Tashkent. The report contrasts a strengthened-rules scenario with two fragmentation scenarios, with least-developed countries facing the steepest losses.

Key Facts

The WTO's 2026 World Trade Report was presented on September 15 at the Public Forum in Tashkent.
Under a strengthened multilateral rules scenario, global GDP could rise 2.9% and global exports 17.9% by 2050 relative to baseline.
In a 'geo-fragmented world' scenario, global GDP would fall 5.1% and exports 18.6%.
In a 'free trade agreements world' scenario, global GDP would fall 6.9% and exports 26.9%.
Least-developed countries, which account for less than 1% of world trade, could see GDP rise 7.7% under strengthened rules but fall 16.5% under the FTA scenario.

Report Scenarios

The WTO report models three scenarios for the global trading system through 2050. Under strengthened multilateral rules, global GDP could rise 2.9% and global exports 17.9% relative to the baseline trajectory. This scenario assumes broader market-opening commitments, new multilateral rules on digital trade and services, expanded WTO membership, and a balanced approach to security. In a 'geo-fragmented world' where trade cooperation aligns with geopolitical blocs, global GDP would fall 5.1% and exports 18.6%. In a 'free trade agreements world' where multilateral cooperation is replaced by a network of FTAs, GDP would fall 6.9% and exports 26.9%.

Vulnerable Economies

Least-developed countries, which currently account for less than 1% of world trade, are the most vulnerable under the fragmentation scenarios. Under strengthened multilateral rules, their GDP could rise 7.7%, while under the FTA scenario it would fall 16.5%. That loss is more than three times the decline projected for high-income economies. High-income economies would gain about $1.7 trillion in 2023 prices under strengthened rules, mainly from lower services trade costs.

System Pressures

WTO Director-General Ngozi Okonjo-Iweala said the global trade landscape has changed substantially but the system's core logic remains as relevant as ever. She noted that about 72% of world merchandise trade still takes place on WTO most-favoured-nation terms. The report identifies four trends complicating cooperation: shifting economic power, growing state intervention including industrial policy, digitalization and global value chains, and rising geopolitical tensions. The report does not offer a ready-made WTO reform plan but points to areas where rules may need to change.
