Are Trump's Tariffs Still In Effect? What To Know After Court Rules Most Levies Are Illegal

An appellate court has ruled that most tariffs imposed by former President Trump were illegal, asserting he exceeded his authority under the International Emergency Economic Powers Act (IEEPA), as the power to impose such levies is exclusively legislative. The U.S. Court of Appeals for the Federal Circuit's 7-4 decision, which upholds a lower court ruling, states the IEEPA does not grant broad tariff authority. While the ruling is stayed until October 14 to allow the Trump administration to appeal to the Supreme Court and tariffs remain in effect, an upheld decision would invalidate "reciprocal" tariffs on key trade partners like China, Mexico, and Canada, potentially altering trade dynamics and market outlook.

Analysis

A U.S. Court of Appeals for the Federal Circuit has introduced significant uncertainty into U.S. trade policy by ruling most tariffs imposed by the Trump administration illegal. In a 7-4 decision, the court affirmed that the president overstepped his authority by using the International Emergency Economic Powers Act (IEEPA) for tariff imposition, a power it deemed "vested exclusively in the legislative branch." Critically, the tariffs remain in effect, as the ruling is stayed until October 14 to permit an appeal to the Supreme Court, an action the White House has confirmed it will pursue. Should the ruling be upheld, it would nullify the "reciprocal" tariffs affecting key trade partners such as China, Mexico, and Canada. However, it would not impact separate tariffs on steel, aluminum, and copper, which were enacted under a different presidential authority. The situation creates a binary risk scenario for companies dependent on international supply chains, with the final outcome contingent on a Supreme Court decision, and the article notes it is unclear how this will ultimately affect existing trade agreements or broader market dynamics.

Key Decisions for Investors

• Investors should closely monitor the Supreme Court's response to the administration's impending appeal, as its decision to hear the case, or not, will be the primary catalyst for resolving the current trade policy uncertainty.
• Review portfolio exposure to sectors with high import volumes from China, Mexico, and Canada, such as retail and manufacturing, which could experience significant margin relief if the tariffs are ultimately voided.
• Anticipate continued volatility and headline risk for assets tied to global trade, as the legal battle and strong political rhetoric will persist until a final judicial resolution is reached.
• It is crucial to distinguish between the tariffs at risk in this ruling and those on industrial metals like steel and aluminum, which are unaffected and will continue to impact relevant sectors.
