The US Supreme Court has invalidated tariffs imposed by the previous administration, prompting a swift response from the current President who announced a new 15% tariff on all imports. This escalation has rattled markets, as the initial tariffs had served as a bargaining chip in securing trade agreements with key partners like the EU. The legal challenge centers on the constitutionality of the tariffs, and the decision opens the door to a wave of litigation from importers seeking refunds.

Why it matters

The Supreme Court's ruling on the unconstitutionality of the unilateral tariffs imposed under the International Emergency Economic Powers Act has significant implications for US trade policy and relations with major trading partners like the EU. The potential for billions in refunds to importers and the suspension of a key trade agreement with Washington underscores the broader economic and geopolitical fallout from this decision.

The details

In a 6-3 vote, the Supreme Court struck down the 'reciprocal' tariffs enacted by the previous administration, with two of the three judges appointed by the former President voting against the legality of the tariffs. In response, the current President announced a new 15% tariff on all imports, up from an initial 10% proposal, in an effort to replace the invalidated duties and leverage new trade negotiations. This move has further rattled markets, as the initial tariffs had served as a bargaining chip in securing trade agreements with the EU, Japan, and the UK. The legal challenge centered on the constitutionality of the tariffs imposed unilaterally under the IEEPA, and while the court did not rule on potential refunds to importers, Bloomberg estimates the figure could exceed $170 billion, more than half the revenue generated by the tariffs. This decision opens the door to a wave of litigation, with more than a thousand legal challenges already underway, including one from shipping giant COSCO.
