Trump Imposes Novel Tariffs After Supreme Court Ruling
The U.S. Supreme Court’s recent decision striking down President Donald Trump’s sweeping tariffs has triggered a swift response from the White House, with the announcement of a new 10% global tariff. This move, coupled with ongoing concerns over Iran’s nuclear program and rising political tensions in France, is reshaping the global geopolitical landscape.
Supreme Court Rejects Trump’s Tariff Authority
On Friday, February 20, 2026, the Supreme Court ruled 6-3 that President Trump overstepped his executive authority when using the International Emergency Economic Powers Act (IEEPA) to impose broad tariffs on U.S. Trading partners. Chief Justice John Roberts, writing for the majority, stated that the President needed “clear congressional authorization” to enact such tariffs, a power not granted by IEEPA. USAToday
The court found that IEEPA does not explicitly authorize the imposition of tariffs and no president had previously interpreted the act to include such power. The ruling casts doubt on the legality of over $175 billion in tariff revenue collected under IEEPA, potentially requiring refunds to companies. USAToday
New Tariffs Under Section 122
In response to the ruling, President Trump announced a new 10% global tariff, this time invoking Section 122 of the Trade Act of 1974. The Guardian This section allows the president to impose tariffs of up to 15% for a maximum of 150 days to address balance-of-payments deficits, but requires congressional approval for extension. The Guardian
Although Trump claims this authority allows for even greater tariff imposition, experts note that Section 122 is more limited in scope and duration than the powers previously claimed under IEEPA. The Guardian
Global Reactions

South Korean government ministers convened an emergency meeting to review the ruling and the new tariff order. CNN The European Union is holding an emergency meeting to reassess its trade agreement with the U.S., while the United Kingdom is seeking clarification on the impact of the ruling on existing tariffs.

Iran Negotiations and Potential Military Action
Alongside the tariff developments, the Trump administration is considering a limited military strike against Iran to pressure Tehran into a nuclear deal. CNN Top Democrats are urging the administration to seek congressional approval before any military action. CNN The U.S. Military has reportedly reached an advanced stage in planning potential targets, including military and government sites. Iran has vowed retaliation in the event of an attack. CNN
Political Tensions in France
Rising political tensions in France are also contributing to the volatile global climate. Police reinforcements have been deployed to Lyon ahead of a planned rally for a far-right activist killed last week. The incident has sparked accusations and counter-accusations between right-wing and left-wing political factions. CNN
The confluence of these events – the tariff dispute, the Iran situation, and the French political unrest – underscores a period of heightened global uncertainty.
