WTO Warns Global GDP Could Decline by Up to 10 Percent by 2050 Without Trade System Modernization

The World Trade Organization (WTO) has issued a warning that failing to modernize the global trading system could result in a decline of up to 10 percent in the world’s gross domestic product (GDP) by 2050. This cautionary outlook was highlighted in the WTO’s “World Trade Report 2026: At a Critical Juncture for the Global Trade System,” released on Tuesday. The report emphasizes that trade policies are facing serious and ongoing challenges that have persisted for decades. It offers a review of the achievements of the multilateral trading system over the past 80 years alongside the current obstacles.

“The multilateral trading system has delivered significant benefits over the last eight decades and has supported the development of a more integrated and resilient global economy,” stated WTO Director-General Ngozi Okonjo-Iweala. She noted that approximately 72 percent of global merchandise trade still operates under WTO’s Most-Favored-Nation (MFN) framework. “Despite notable transformations in the global trade landscape, the core principle upon which this system was established—that cooperation, not unilateralism, benefits all economies—remains highly relevant today,” she added.

Director-General Okonjo-Iweala also indicated that WTO member countries are actively engaged in discussions about the necessary reforms and stressed that maintaining the status quo is not an option. The report outlines three potential future scenarios for the global trade system. Should a robust multilateral system persist, baseline projections estimate that global GDP could increase by 2.9 percent and exports by 17.9 percent by 2050.

Conversely, if multilateral trade rules weaken and trade cooperation shifts toward geopolitically driven alliances, global GDP could decline by 5.1 percent and exports by 18.6 percent, according to the report. In the scenario where multilateral cooperation is replaced by independent trade agreements, global GDP is projected to fall by 6.9 percent and exports by 26.9 percent. Robert Stiger, WTO’s chief economist, noted that the difference in real global GDP between strong multilateral cooperation and a weakened trade system could be as much as 10 percent.

The report also highlights that over more than eight decades, the multilateral trading system has played a vital role in reducing trade barriers, expanding global trade nearly fiftyfold, and contributing significantly to building a more integrated and rule-based global economy.
