WASHINGTON – U.S. Stock futures declined sharply early Monday as President Donald Trump responded to the Supreme Court’s Friday ruling against his global tariffs by announcing a new 10 percent levy on a broad range of imported goods. The immediate imposition of the new tariffs has injected further uncertainty into global trade and prompted concerns about escalating economic tensions.
The Supreme Court, in a 6-3 decision, struck down the tariffs initially imposed by Trump, finding that the law used to justify them did not authorize the President to impose such duties. Chief Justice John Roberts delivered the court’s opinion, with Justices Clarence Thomas, Samuel Alito, and Brett Kavanaugh dissenting. The ruling represented a significant rebuke of Trump’s signature economic policy, which he had characterized as essential for protecting American industries and jobs.
The initial tariffs, implemented during Trump’s second term, had been widely criticized by trading partners and domestic businesses alike. Opponents argued they raised costs for consumers and disrupted supply chains. The court’s decision was hailed by many as a restoration of congressional authority over trade policy, as the Constitution grants Congress the power to tax.
However, Trump’s swift response – the announcement of the new 10 percent tariffs – has undermined any sense of resolution. The White House did not specify which goods would be subject to the new tariffs, only stating that they would be applied “across the board.” This lack of specificity has fueled anxiety among businesses and investors.
Wall Street reacted negatively to the news, with S&P 500 futures falling 0.8 percent, Nasdaq futures dropping 1.2 percent, and Dow Jones Industrial Average futures declining 0.7 percent in early trading. The dollar also weakened as traders sold off U.S. Assets in response to the escalating trade risks. Asian markets showed a mixed response, with some indices rising while others declined.
The European Union issued a statement expressing concern over the new tariffs, calling on the U.S. To honor existing trade agreements. The statement followed a similar rebuke from the EU after the initial Supreme Court ruling, where they urged the U.S. To abide by international trade rules.
The CNBC report noted that Trump’s legal stance on tariffs “would represent a transformative expansion of the President’s authority over tariff policy.” The Supreme Court majority explicitly rejected this expansion, emphasizing the constitutional role of Congress in regulating trade. The ruling is expected to trigger a wave of legal challenges to any future attempts by the President to impose tariffs without congressional authorization.
As of Monday morning, the White House has remained silent on the specific legal justification for the new tariffs, and no timeline for their implementation has been announced. The Office of the U.S. Trade Representative has not responded to requests for comment.
