The Supreme Court has struck down a large portion of the tariffs that are a key element of President Trump's economic agenda. By a six-to-three majority, the court ruled that the law cited by the administration to levy trade duties 'does not authorize the president to impose tariffs.' Many, though not all, tariffs during the second Trump administration have been imposed under the International Emergency Economic Powers Act (IEEPA). The IEEPA, which makes no mention of tariffs, gives the president the power to regulate imports of foreign property but only after declaration of a national emergency to deal with tangible threats. The administration's use of IEEPA was considered unconventional. The court's ruling relates to reciprocal tariffs as well as those imposed to impede illegal drug flows. The stock market so far has had a guardedly optimistic response to the ruling. Meanwhile, fourth-quarter GDP data, also released today, highlighted the impacts of the government shutdown; but some economists also noted the potential impact of tariffs on government and business spending. The administration may look to work around the ruling by enlisting help from Congress. In the intermediate term, the uncertain future of tariff policy may overhang the market.
