US Supreme Court Overturns Critical Tariff: Potential Risks for Global Trade and Turkey

Supreme Court Ruling and Uncertainty in Trade Policy In a landmark decision on February 23, 2026, the US Supreme Court overturned a controversial tariff regulation that had been implemented previously.
This ruling has sparked widespread debate within international trade circles regarding the future of protectionist policies.
However, experts agree that this legal victory is far from ending global trade tensions.
The decision's political and economic repercussions may be more limited than expected.
Presidential Powers and New Tax Mechanisms Professor Dr.
Pınar Artıran, the WTO Chair at Istanbul Bilgi University, noted that the canceled regulation is not the only instrument available to the US administration.
She highlighted that new tariff mechanisms could be activated under different legal frameworks within the scope of presidential powers.
Additional taxes against unfair trade practices, anti-dumping processes, and subsidy investigations are expected to regain momentum in the coming period.
Shift from Multilateral Systems to Bilateral Negotiations The ruling is anticipated to trigger a more fragmented structure rather than strengthening the World Trade Organization (WTO)-centered multilateral trade system.
Artıran stated that the US has preferred bilateral pressure and negotiation methods over institutional mechanisms in recent years, which reduces predictability in global trade.
Warnings were issued that a chaotic system managed through bilateral negotiations presents new challenges for developing economies.
Turkey's Export Sectors and Strategic Risks The effects of the decision are expected to be felt particularly in Turkey's leading sectors, such as textiles and automotive.
Regarding the discussions on a 15% general tax equalization, Prof.
Artıran stated that such an application would violate international trade law but would create serious cost pressure and competitive disadvantages for Turkish exporters if implemented.
Furthermore, it was emphasized that free trade agreements the European Union might sign with third countries could weaken Turkey's Customs Union advantages, making it critical for Ankara to take strategic and parallel steps.
Refund Process Begins for Importers The Supreme Court's cancellation has also opened a new legal avenue for US importers who previously paid duties under these tariffs.
Companies may initiate legal proceedings to reclaim the taxes paid, which is expected to directly impact both US public finances and the balance sheets of international corporations.
Experts warn that this short-term relief may be balanced by more complex legal and political moves in the long run.
