In February 2026, the U.S. Supreme Court struck down the tariffs President Trump had imposed under emergency powers, ordering hundreds of billions of dollars in duties refunded to importers. Within days, the administration invoked a different legal authority to reimpose a 10% global tariff, only for a federal trade court to strike that down too, in May. The whiplash captures where global trade policy stands in 2026.
The pattern indicates that there is a constantly shifting patchwork of duties, safeguards, and retaliations that businesses now have to plan around as a permanent feature. The Yale Budget Lab estimated the U.S. average effective tariff rate reached 11.8% by April 2026, marking the highest level since the early 1940s before easing towards 7% as temporary measures lapsed.
The Tax Foundation calculates the tariffs cost the average American household about $1,000 in 2025 and will add roughly $700 more in 2026. Federal Reserve researchers have traced a direct line from the levies to prices, exploring how tariffs implemented through late 2025 pushed core goods inflation up significantly by early 2026.
Crucially, the trend is no longer a bilateral U.S.-China story. A joint WTO and IMF tracking index found global trade-policy activity running nearly double 2024 levels in the first five months of 2026. Protectionism has been widely adopted as a defensive reflex by importers and competitors globally, reshaping supply chains and increasing costs for small businesses.
