In the October update of "Global Trade Outlook and Statistics", WTO economists provide new analysis on the build-up in inventories in 2025 and the robust trade in artificial intelligence-related goods such as semiconductors, servers, and telecommunications equipment.
They note however that trade growth will likely slow in 2026 as the impact of the cooling global economy and new tariffs set in.
Director-General Ngozi Okonjo-Iweala said: "Countries' measured response to tariff changes in general, the growth potential of AI, as well as increased trade among the rest of the world, particularly among emerging economies, helped ease trade setbacks in 2025," noting that South-South trade grew 8% year-on-year, in value terms, in the first half of 2025, compared to 6% for world trade overall. South-South trade involving partners other than China is growing even faster, up around 9%.
"Trade resilience in 2025 is thanks in no small part to the stability provided by the rules-based multilateral trading system. Yet complacency is not an option. Today's disruptions to the global trade system are a call to action for nations to reimagine trade and together lay a stronger foundation that delivers greater prosperity for people everywhere," Okonjo-Iweala said.
The volume of world merchandise trade, as measured by the average of exports and imports, grew 4.9% year-on-year in the first half of 2025. The value of world merchandise trade in current US dollar terms was up 6% year-on-year in the first six months of 2025 following a 2% increase in 2024.
Trade growth drivers in the first half included the frontloading of imports in North America and favorable macroeconomic conditions such as disinflation, supportive fiscal policies, and strong growth in emerging markets. Industry reports, including purchasing managers' indices (PMIs) and national statistics, show rising inventories, with inventories-to-sales ratios in North America increasing in the first half of 2025 across sectors like machinery, motor vehicles, lumber, construction equipment, and non-durable goods
AI-related goods—including semiconductors, servers, and telecommunications equipment—drove nearly half of the overall trade expansion in the first half of the year, rising 20% year-on-year in value terms. Trade growth spanned the digital value chain, from raw silicon and specialty gases to devices powering cloud platforms and AI applications. Asia's export performance was strong in AI-related products, consistent with the worldwide surge in investment in this sector.
Higher tariff rates and elevated trade policy uncertainty are set to eventually unwind some of the effects of earlier frontloading. Already, rising input prices and a slowdown in trade shipments suggest inflation could increase in late 2025 as inventories shrink in tariff-affected, highly-exposed sectors. With higher tariffs taking effect in August, some of the impacts projected in the WTO Secretariat's April 2025 forecast are now likely to materialize later in the year and into 2026.
World merchandise trade volume growth is expected to slow from 2.8% in 2024, to 2.4% in 2025 and 0.5% in 2026. The projection for global GDP growth is 2.7% for 2025 and 2.6% for 2026. While the 2025 merchandise trade forecast has been revised upwards from the April and August projections, the downgrade for 2026 results in a similar overall impact over the two-year horizon. This indicates that the tariff impact has shifted into 2026, with the slight improvement reflecting that some inventory build up in early 2025, particularly of durable goods, will not be fully reversed in 2026.
WTO economists highlight that the key downside risk to the forecast is the spread of trade-restrictive measures and policy uncertainty to more economies and sectors. On the upside, sustained growth in trade for AI-related goods and services could provide a medium-term boost to global trade.
Asia and Africa are expected to record the fastest export volume growth in 2025, with modest performances also anticipated from South and Central America the Caribbean and the Middle East, while Europe will likely see slower growth. North America and the Commonwealth of Independent States (CIS) face declining exports. Least-developed countries (LDCs) are expected to show robust export gains but face weakening trends ahead. On the import side, Africa and LDCs are set to experience the fastest growth, contrasting with a contraction in North America. In 2026, only North America, Europe and CIS will post an improvement in export performance; all regions will record weaker import performance in 2026.
