In a significant twist for the markets, U.S. stocks experienced a rally on Friday following a landmark ruling from the Supreme Court that declared Donald Trump’s tariffs illegal. This decision reversed earlier declines and has injected a fresh wave of optimism among investors, who were previously grappling with uncertainty surrounding the controversial trade policies that were first introduced in April of last year.
The Supreme Court’s ruling has not only provided clarity on this contentious issue but has also raised questions about how Trump and his administration may pursue alternative avenues for implementing tariffs. Trump’s economic team has already indicated that there are numerous other options available should they need to navigate around the court’s decision. Matthew Ryan, head of market strategy at Ebury, emphasized that while short-term disruptions may follow, the long-term strategy for tariffs seems resilient as the White House could explore different methodologies to continue its agenda.
As trading settled on Thursday afternoon, major U.S. indexes showed notable improvement, suggesting a positive market sentiment. The ruling provided a welcome distraction from a disappointing economic report that revealed GDP growth of only 1.4% year-over-year, significantly trailing expectations. Compounding concerns, the Personal Consumption Expenditures (PCE) index—the Federal Reserve’s preferred inflation measure—rose by 0.4% in December, surpassing the anticipated increase of 0.3%.
Jose Torres, a senior economist with Interactive Brokers, reflected on the market response, stating, “The market just totally erupted.” He noted that while the economic growth figures were lackluster, the tariff ruling had revitalized corporate earnings prospects, thus benefitting investors. Additionally, there is speculation about potential corporate stimulus resulting from the government potentially refunding tariffs previously paid by firms—a move that could further boost investor confidence, according to Michael Brown, a senior research strategist at Pepperstone.
However, experts are advising caution. Despite the Supreme Court’s ruling being viewed as a setback for Trump’s administration, analysts like Brown caution that the President is likely to seek alternative methods to impose tariffs, suggesting that fundamental changes in policy may not be imminent. “From a tariff perspective, nothing is likely to change particularly much,” he added.
Torres also commented on the broader landscape of the stock market, which has been under pressure recently, with sell-offs affecting various sectors, including software, insurance, and real estate. He noted the recent rally is a sign that investors are eager to generate upward momentum in what has been an uncertain market climate.
As the market digests the implications of the Supreme Court ruling, all eyes will remain on the administration’s next steps and the potential for new strategies in the ongoing trade war.
