The Trump administration has entered a critical 150-day period for its trade policy after a Supreme Court ruling invalidated its previous tariff framework. On February 20, 2026, the Court ended the use of the 1977 International Emergency Economic Powers Act for levying duties, leading to the immediate termination of several major trade barriers. To prevent a total lapse in its protectionist agenda, the President invoked Section 122 of the 1974 Trade Act to implement a stopgap 10% global tariff.
This temporary measure is legally capped at 150 days and is scheduled to end in late July unless extended by Congress. President Trump has signaled a desire to push the rate to 15%, the maximum allowed under the statute, to maximize leverage in upcoming negotiations. The administration is also reviewing “de minimis” rules to ensure that small-value shipments continue to face standard duties despite the broader court-ordered changes.
The focus of the U.S. Trade Representative has now shifted to launching massive “Plan B” investigations. These probes into 16 major economies are examining whether foreign government subsidies have led to overproduction in sectors like automobiles, batteries, and semiconductors. If these practices are deemed “unreasonable,” they could provide the legal basis for a new wave of permanent tariffs that are more resilient to court challenges.
Diplomatic pressure is mounting as these temporary measures tick toward expiration. Talks in Paris between U.S. and Chinese negotiators are currently laying the groundwork for a late-March presidential summit in Beijing. Simultaneously, discussions with Mexico are intensifying over “rules of origin” and supply chain security, highlighting the fragility of the North American trade relationship amid the President’s “constantly changing” tariff policies.
The administration’s aggressive stance has also triggered friction within NATO, particularly with Spain. After Madrid blocked the use of its bases for strikes in the Middle East, the President threatened “trade reprisals” against the Spanish economy. This move has raised concerns among European leaders about the potential for targeted trade wars against allies who do not align with U.S. military or geopolitical objectives.
