Financial markets responded with mixed signals Friday after the U.S. Supreme Court struck down President Donald Trump’s extensive tariff program, delivering a blow to the administration’s trade policy while creating new concerns about government spending.
The high court’s decision validated a lower court ruling that determined the Republican president overstepped his legal authority when implementing the import duties under a 1977 statute. Stock markets initially climbed roughly 0.5% following the announcement, with retail companies and consumer-focused businesses leading the gains, though some of those increases faded within an hour.
The ruling potentially requires the federal government to reimburse between $150 billion and $200 billion to domestic and international companies that previously paid these trade duties. This development could particularly benefit automobile manufacturers and businesses that import consumer products.
However, the decision also triggered concerns in bond markets, where 10-year Treasury yields rose to 4.102% as investors worried about the government’s fiscal position.
“The big question for everyone is what exactly happens to refunds and whether this means the government has to refund the tariff revenue and how quickly that happens. And the key source of uncertainty is what the administration does in response,” explained Gennadiy Goldberg, who leads U.S. rates strategy at TD Securities in New York.
Goldberg added that “What matters for the fixed income market is forward collections of tariffs.”
Economists from Penn-Wharton Budget Model estimated the potential refund amount at approximately $175 billion, according to Friday reports. However, trade law specialists caution that the reimbursement process will likely face significant legal challenges, making refunds far from certain.
The court’s action raises questions about projected government revenue streams that could total trillions of dollars over the coming decade, money needed to manage the nation’s $30 trillion debt load. This uncertainty adds to existing market anxiety about America’s deficit spending and might prompt bond investors to demand higher yields on government securities.
“Fixed income yields jumped over concerns that the U.S. Treasury is now going to have to pay a significant amount back to U.S. corporations. This would lead to a higher deficit and a potential degradation in credit standards of the United States,” stated Phil Blancato, chief market strategist at Osaic in New Jersey.
Trump’s April 2nd “Liberation Day” tariff announcement had previously caused significant disruption in global stock and Treasury bond markets, with his unpredictable trade approach continuing to create market volatility throughout the past year, including a major selloff in October.
Earlier bond market turmoil in April had forced the administration to scale back some of its tariff plans, leading to pauses in certain duties while pursuing new trade deals and reducing others after agreements were reached. Companies worldwide have filed thousands of lawsuits challenging the tariffs’ legality while seeking refunds.
Eddie Ghabour, CEO of KEY Advisors Wealth Management, warned that another surge in Treasury yields could become a “major headwind for markets.”
Some market participants believe the administration will find alternative legal pathways to reimpose similar tariffs, potentially limiting the long-term impact of Friday’s Supreme Court decision.
“I think the Trump administration has contingency plans in place,” said Jeff Leschen, managing director at Bramshill Investments in Florida, noting that investors need time to process the news. “I don’t expect there will be major revisions to the S&P targets for the year.”
The ruling could negatively affect investor confidence, particularly for those anticipating Trump will pursue alternative methods to restore import duties. This uncertainty may impact sectors with substantial international revenue or those vulnerable to raw material and component price changes, including technology, materials, energy, and industrial companies.
