The US Supreme Court could rule on the president’s legality on Friday Donald TrumpTariffs, a decision likely to have considerable impacts not only on trade policy, but also on the budgetary situation of the United States.
Although it is unclear whether the High Court will issue its decision, it has scheduled Friday as a “decision day” to issue its opinions, and there is widespread speculation that the tariff case will be raised.
Basically, the decision will address two questions: whether the administration can use provisions of the International Emergency Economic Powers Act whether to lift tariffs, and if that is not appropriate, whether the United States will have to reimburse importers who have already paid the duties.
However, the final decision could also lie somewhere in between.
The court has the ability to grant limited powers under IEEPA and require only limited reimbursement, as well as many other options on how it handles a sensitive issue that is closely watched on Wall Street.
Furthermore, even if the White House lost its case, it would have other tools in his chest to implement tariffs that do not require the emergency powers cited in the law.
Treasury Secretary Scott Bessent himself said Thursday that he expected a “hodgepodge” decision.
“What is beyond doubt is our ability to continue to collect tariffs at about the same level, in terms of overall revenue,” Bessent said during an appearance in Minneapolis. “What is questionable, and it is a real shame for the American people, is that the president loses the flexibility to use tariffs both for national security and as negotiating leverage.”
Trump used IEEPA in part as an emergency measure to stop the flow of fentanyl into the United States.
The impact of loss
Removing tariffs would have multiple consequences, said Jose Torres, senior economist at Interactive Brokers.
“If the court blocks the tariffs, the administration will find solutions,” Torres said. “President Trump is very ambitious in passing this agenda despite the potential controversies that could surround such a decision.”
“Blocking tariffs would harm reshoring ambitions. It would be bad for fiscal conditions, rates would increase,” he added. “But it would be good for corporate profits. Input prices would be lower and trade would be smoother.”
Administration officials cited a number of options to counterbalance the court’s decision if it doesn’t go their way. Prediction Markets Site Kalshi points there is only a 28% chance that the court will rule in favor of the tariffs as implemented. Torres said his firm’s clients have similar expectations.
Bessent said the administration had at least three other options thanks to the Trade Act of 1962 which will keep most tariffs in place. However, he also worries that the refunds could strain the administration and its efforts to reduce the budget deficit. Tariffs brought in some $195 billion in fiscal 2025 and another $62 billion in 2026, according to Treasury data.
Ultimately, Morgan Stanley analysts “see significant room for nuance” in the Supreme Court’s decision.
The court “has wide latitude when making rulings; a range of outcomes are possible, such as the Court reducing the scope of existing tariffs but not requiring their complete removal or limiting future application of the tariffs,” Morgan Stanley analysts Ariana Salvatore and Bradley Tian said in a note.
“We believe it is possible for the administration to take a lighter approach to the overall tariff regime given the recent policy emphasis on affordability,” they added.
So far, the impact of the tariffs has defied analysts’ projections: there has been a limited impact on inflation, while the trade deficit has plungedthwarting expectations among some that the tariffs could make the United States a pariah on the global trade stage. October’s trade imbalance reached its lowest level since the end of the financial crisis in 2009, at a time when imports had fallen sharply due to the massive recession generated by the crisis.
