Trump Hikes Global Tariff to 15% After Supreme Court Rejects Levies

Introduction: A Swift Response to a Judicial Setback

US President Donald Trump announced on Saturday an immediate increase of a newly established global import tariff from 10% to 15%. This move came just one day after the US Supreme Court delivered a significant blow to his trade agenda, striking down the sweeping tariffs he had imposed under emergency powers. Characterizing the court's decision as "extraordinarily anti-American," the President signaled his intent to use alternative legal channels to maintain his protectionist trade policies, creating fresh uncertainty for global markets and trading partners, including India.

The Supreme Court's Landmark Decision

On Friday, February 21, the Supreme Court ruled in a 6-3 decision that President Trump had overstepped his authority by unilaterally imposing widespread tariffs. The majority opinion, written by Chief Justice John Roberts, stated that the International Emergency Economic Powers Act (IEEPA) of 1977 does not grant the president the power to levy broad, economy-wide tariffs. The court affirmed that the constitutional power to set taxes and duties rests with the US Congress. The ruling invalidated the legal foundation for a significant portion of Trump's tariff regime, which had collected over $133 billion in import taxes. The decision, however, left unanswered the question of what would happen to the funds already collected.

Trump's Immediate Retaliation

Reacting swiftly to the judicial setback, President Trump took action within hours. On Friday evening, he signed an executive order invoking a different legal authority, Section 122 of the Trade Act of 1974. This provision allows the president to impose a temporary import surcharge for up to 150 days to address a balance-of-payments deficit. Under this order, a new 10% global tariff was set to take effect on February 24, 2026. This initial step ensured that a tariff structure remained in place despite the Supreme Court's ruling, albeit under a more limited and temporary legal framework.

Escalation to the 15% Maximum

Less than 24 hours later, President Trump escalated his response. In a post on his Truth Social platform on Saturday, he announced that the 10% tariff would be immediately raised to 15%. He stated the decision followed a "thorough, detailed, and complete review of the ridiculous, poorly written, and extraordinarily anti-American decision on Tariffs issued yesterday." The 15% level represents the maximum surcharge allowed under Section 122, indicating the administration's intent to push its authority to the legal limit. Trump further added that his administration would, "during the next short number of months, determine and issue the new and legally permissible tariffs" under other authorities.

Legal and Constitutional Context

The rapid shift in legal justification from the IEEPA to Section 122 highlights the administration's search for alternative tools to pursue its trade agenda. Legal experts noted the distinction. Jonathan Adler of William & Mary Law School remarked, "The President cannot just pour new wine out of old bottles. If there are problems current statutes do not address, the president must ask Congress for a newer vintage." The new 15% tariff is temporary and will expire after 150 days unless Congress votes to extend it, setting the stage for a potential confrontation between the White House and lawmakers.

Impact on Global Trade and India

The fluctuating tariff landscape has created significant confusion for global businesses and US trading partners. For India, the situation has been particularly volatile. Last year, India faced 25% reciprocal tariffs, which were later increased to 50% over its Russian oil imports. In February 2026, this rate was reduced to 18% following an interim trade framework agreement. While the Supreme Court ruling initially suggested a potential rollback to pre-Trump tariff levels of around 3.5%, the new 15% global tariff changes the calculation. India's effective tariff rate would now stand at 18.5%, a marginal increase over the recently negotiated 18% rate, but still far from a return to lower, pre-existing levels.

A President's Unprecedented Criticism

President Trump's reaction was marked by unusually direct and personal criticism of the Supreme Court justices. He expressed that he was "absolutely ashamed" of the judges who ruled against him, including his own appointees, Justices Neil Gorsuch and Amy Coney Barrett. At a news conference, Trump said of their decision, "I think it’s an embarrassment to their families." He praised the three dissenting justices—Brett Kavanaugh, Clarence Thomas, and Samuel Alito—for supporting his agenda. This public rebuke of the judiciary, particularly of justices he appointed, underscores the political intensity surrounding his signature economic policies.

Key Tariff Developments at a Glance

What Lies Ahead

The 15% tariff under Section 122 is a temporary measure. President Trump has already indicated that his administration is preparing to use other legal provisions, such as Sections 232 and 301 of trade law, to impose new, more durable tariffs. These actions would likely involve investigations by the Commerce Department into trade practices of other countries. This strategy suggests that the 15% levy is a stopgap measure designed to maintain pressure while a more permanent tariff structure is developed, ensuring that trade policy remains a central and contentious issue.

Conclusion

The events of the past 48 hours represent a significant clash between the executive and judicial branches of the US government over trade authority. While the Supreme Court reasserted Congressional power in setting tariffs, President Trump demonstrated his resolve to use every available legal tool to continue his protectionist policies. The immediate imposition and subsequent increase of a new global tariff ensures that trade relations will remain fraught with uncertainty, leaving global businesses and partner nations to navigate a complex and rapidly changing policy environment.
