Fridays were reserved for the usual headlines. Since Donald Trump was re-elected, Fridays have become a day of explosive news.
Last Friday, the US Supreme Court delivered a constitutional shock to global commerce. The US Supreme Court, in a ruling of 6-3, struck down the use by President Donald Trump of his emergency powers to impose tariffs. This removed the “on/off” switch that defined Trump’s trade policy.
In just a few hours, Trump raised the tariff from 10% to 15% under Section 122 (the 1974 Trade Act).
The implications of Trump’s tariffs are huge. The implications are huge for the US, China, Europe, India, and all other trading partners.
What was stopped by the court and what remains
The Court found that the International Emergency Economic Powers Act did not authorize a President to raise tariffs. John Roberts, Chief Justice of the United States wrote that if Trump were to be accepted as reading his interpretation it would mean a “transformative extension” of executive power. Congress has the right to impose taxes.
Other statutes still exist. The Section 122 tariff allows for a maximum of 15% in 150-day periods.
After investigations relating to national security, safeguards or unfair trading practices, Sections 201 232 301 permit duties. Trump immediately moved to Section 122 and set a global 15% rate.
Bloomberg predicts that the average effective tariff will remain at around 11 to 12 percent, or four times what it was before Trump.
Goldman Sachs estimates that since the beginning of 2025, tariffs will increase by just under 10 percent points.
Although the legal system has changed, economic pressures remain high.
What is the leverage question?
Prior to the decision, the White House was able to impose tariffs on specific countries in a matter of days. This tool requires investigation and procedural measures. Speed is lost.
China is the first to notice a difference.
Morgan Stanley predicts that the average weighted tariff rate for Asian exports will drop from 20 to 17 percent.
The average levies for Chinese products have dropped from 32 to 24 percent. Tariffs on fentanyl of 10% are gone. Beijing will be less pressed at the summit on March 31.
US Trade Representative Jamieson Greer insisted that the administration has leverage. He said: “We already have these tariffs in place against China and we are conducting open investigations.”
Tariffs against China are still around 40 percent for other governments.
Escalation is also slower and more discretionary. In negotiations, speed often equals strength.
Europe’s Credibility Test
The European Union agreed to a deal last summer that included a US 15% tariff on the majority of EU exports, while eliminating tariffs for American products entering the EU.
Metals from Europe are still subject to 50% duty.
This agreement was intended to prevent a wider trade conflict.
Now, European legislators are reconsidering. Members of the European Parliament’s Trade Committee called it “pure chaos in customs” and suggested freezing the ratification process until there is clarity from the US.
The President of the European Central Bank, Christine Lagarde, said that knowing rules before trade commitments is “critically” important.
Predictability is her main concern. Business had become accustomed to previous arrangements. This equilibrium is undermined by rapid resets.
US policy is one of continuity, as the US claims that current agreements are valid and should be respected by all parties.
This tension is revealing a variable new to global trade. The issue isn’t the tariff headline rate, but rather whether the counterparties have confidence in the US.
What is the winner and what are the losers of 15%
With the new global 15% tariff, differences between countries are reduced. This creates winners.
China, India and Brazil enjoy lower rates than the emergency regime that has been invalidated.
Canada and Mexico benefit from the USMCA exemptions and removal of duties related to fentanyl if they remain in place.
After the decision, Chinese stocks in Hong Kong rose.
Countries like the UK, Australia and others that previously negotiated at 10% now pay 15%. Japan’s relative advantage is lost at this level.
Bloomberg estimates that under the new regime, the average effective tariff has fallen to 12%. This is the lowest rate since April’s so-called Liberation Day Tariffs.
Goldman Sachs anticipates a pickup in the imports of countries that are experiencing reductions. However, overall GDP effects will be limited because inventory adjustments and rerouting should limit any impact.
Tariffs: Are they economically beneficial?
The original goals of the administration with tariffs was to reduce trade deficits and revitalize manufacturing.
A recent analysis shows who paid the final cost of import duties, and the impact on prices and growth.
The US trade deficit is largely unchanged. Manufacturing hasn’t experienced a sustained recovery. And the majority of tariffs have been transferred to American consumers and importers, rather than being absorbed by exporters from abroad.
Although the economy avoided a severe downturn thanks to strong AI investment, it has not yet achieved its structural transformation.
Power debate and refund overhang
The Court’s final decision could result in up to $170 Billion of refunds for importers. Over 1,500 lawsuits were filed with the US Court of International Trade.
The economists of Yale’s Budget Lab believe that if refunds are made in 2026 they may temporarily counteract the growth drag caused by remaining tariffs.
The greater consequence, however, is geopolitical. Geopolitical.
The White House could raise or decrease tariffs against specific countries under IEEPA almost immediately.
This tool allows Trump to threaten European governments when disputes arise over Greenland, defence expenditures, or soybean purchases, as well as to tie tariff relief with concrete concessions, such a rare earth flow or the purchase of soybeans.
This gave the president direct influence over foreign governments as well as multinational corporations. This instrument has now been restricted.
Trump still has the option to impose tariffs on Sections 301 and 232. However, this requires time for investigations. Section 122 limits rates to 15% for 150 days.
It is less surprising. It is less credible to say that overnight escalated violence will occur.
China is now facing lower tariff average pressure. European legislators are questioning openly whether they should freeze the ratification. India has delayed the discussions.
Allies who once enjoyed preferential treatment now find themselves on a level playing field.
Prior to the decision, there was a lot of leverage in unilateral actions. Persuasion, statutory processes and legal process are more important now.
Protectionism remains. Protectionism remains. The presidency does not have the same level of discretion. Speed and asymmetries are often the defining factors of bargaining power in global trade politics. These have been reduced.
