WTO Cuts Global Trade Forecast to 1.9% as Strait Crisis Collides With Tariff Refund Liability

The World Trade Organization's latest Global Trade Outlook and Statistics projects merchandise trade volume deceleration to 1.9% growth in 2026, sharply down from the 4.6% rate in 2025. The primary drivers are the Strait of Hormuz closure, which eliminates transit capacity for 20% of global oil and one-third of fertilizer shipments, and the residual impact of US tariff policy uncertainty. The Hormuz disruption is providing the exogenous supply shock. The tariff policy rupture is providing the demand-side uncertainty. Together, they are creating a two-front contraction in global goods flows.

The tariff dimension adds regulatory-liability complexity. On February 20, 2026, the US Supreme Court altered the legal basis for several tariff regimes, creating immediate refund exposure. According to US Customs and Border Protection data compiled by IndexBox, approximately USD 166 billion in tariffs collected under now-questionable legal authority could be subject to repayment across approximately 330,000 importers. The precise refund mechanism remains unclear—hence "legal uncertainty" rather than "legal liability"—but the tail-risk exposure is substantial for logistics, retail, and manufacturing sectors that absorbed those tariffs.

The compounding effect is a three-layer trade shock: the energy-price shock (Hormuz closing = crude oil at USD 110+ = input cost increases across all energy-dependent manufacturing), the supply-disruption shock (Hormuz closing = fertilizer shortage = agricultural cost increases), and the regulatory-uncertainty shock (tariff refund questions = balance-sheet risk for importers = deferred purchasing). Individually, each creates friction in trade flows. Simultaneously, they create a demand pause—importers are delaying forward commitments until tariff questions clarify and Hormuz status stabilizes.

The freight cost premium is direct. Shipping lines have imposed USD 1,500 per-container war-risk surcharges. Alternative routing (land-bridge around the Hormuz chokepoint via Saudi pipelines and rail) increases transit times and costs. Container availability is tightening as the global pool of Empty Container Units concentrates in Western nodes (US, Europe) while Asian export capacity is constrained by Hormuz closures. Lagos port is experiencing acute container shortages as exporters cannot find equipment for cargo movement. The cost of logistics has risen while the reliability of logistics has fallen—exactly the combination that freezes trade.

For trade finance professionals: the USD 166 billion refund exposure creates secondary liability cascades. Importers that collected these tariffs and passed them to end customers may face clawback requests if refunds are mandated. Insurance policies written on tariff pass-through may be triggered. Duty-drawback claims filed before the Supreme Court decision may be subject to adjustment. Customs brokers face potential liability for improper duty payment advice. The regulatory clarity window is still open, but it is narrowing. Advance planning is now critical.

The WTO's 1.9% forecast assumes the Hormuz situation resolves within 6-12 months and tariff regulatory framework stabilizes. If either assumption fails, the 2026 trade forecast could drop below 1.5%—the slowest global trade growth rate since the 2008-2009 financial crisis. Shipping companies dependent on containerized cargo volumes should prepare for reduced utilization rates and reduced per-container revenue. Manufacturing companies should prepare for extended supply-chain cycle times and elevated logistics costs persisting into Q3 2026.

The precedent-setting risk is geopolitical rather than economic. Two major shock categories (energy supply, regulatory trade policy) are arriving simultaneously. Governments facing domestic cost-of-living pressures will face pressure to ease tariff exposure and accelerate trade rules clarification. The risk is that competing trade blocs use the moment to fragment trade rules further rather than harmonize them—accelerating the shift from globalized to regionalized supply chains. The WTO's projections assume continued rules-based trade. If the next 12 months see regional trade blocs building walls rather than bridges, the 2026 forecast becomes optimistic by years, not quarters.
