Gold, silver futures close lower Tuesday

International gold and silver prices closed lower on Tuesday, weighed down by a stronger U.S.dollar.

On the New York Mercantile Exchange, gold futures for December delivery lost 0.44 percent to settle at 4,332.80 U.S. dollars per ounce, while silver futures for December delivery also dropped 0.44 percent to close at 63.856 dollars per ounce.

The World Trade Organization (WTO) warned Tuesday that failure to modernize the global trading system could leave global GDP as much as 10 percent lower than under a strengthened multilateral system, as trade policy faces its most serious and sustained disruption in decades.

The warning came in the WTO's annual flagship publication, World Trade Report 2026: A Critical Juncture for the World Trading System, which examines the achievements of the multilateral trading system over the past 80 years and the challenges it now faces.

"The multilateral trading system has delivered enormous benefits over the past 80 years, helping to create a more integrated and resilient global economy," WTO Director-General Ngozi Okonjo-Iweala said.

About 72 percent of global merchandise trade still takes place under the WTO's most-favored-nation terms, she said.

The global trading landscape has changed significantly but the founding logic of the system, that all economies are better off cooperating rather than acting unilaterally, remains as relevant today as ever, Okonjo-Iweala said.

She said WTO members are actively discussing reforms and recognize that "the status quo is not an option."

The report models three possible futures for the global trading system.

Under a strengthened multilateral framework, global GDP could rise 2.9 percent and exports 17.9 percent by 2050 compared with the baseline trajectory.

The other two scenarios envision an erosion of multilateral trade rules. In a "geo-fragmented world," where trade cooperation is organized around geopolitical blocs, global GDP could fall 5.1 percent and exports 18.6 percent, while in a world where multilateral cooperation is replaced by a network of free trade agreements, GDP could fall 6.9 percent and exports 26.9 percent.
