📰 Top Global Headline — U.S. Supreme Court Strikes Down Major Tariffs

In a 6–3 decision, the Supreme Court struck down some of former President Donald Trump’s most expansive tariffs, ruling they were improperly justified under emergency powers meant for national crises. The ruling is expected to reshape U.S. trade policy and ease global supply chain tensions, with ripple effects on global markets and international trade relationships.

🏛️ Politics & International Relations

• Ukraine war diplomacy: As Europe marks the fourth anniversary of Russia’s invasion, Ukrainian President Volodymyr Zelenskyy reiterated calls for renewed peace talks involving the U.S. and Russia.

• Supreme Court Strikes Down Trump's Tariffs In a landmark 6-3 decision, the U.S. Supreme Court ruled that President Trump violated federal law when he unilaterally imposed sweeping tariffs using the International Emergency Economic Powers Act (IEEPA). The ruling in Learning Resources Inc. v. Trump strikes down all IEEPA tariffs, including the "Liberation Day" reciprocal tariffs and border security tariffs on China, Mexico, and Canada. The court found that IEEPA does not authorize the president to impose tariffs. Chief Justice John Roberts joined Justices Sotomayor, Kagan, Gorsuch, Barrett, and Jackson in the majority, while Justices Thomas, Kavanaugh, and Alito dissented. The case has been remanded to the U.S. Court of International Trade to address refunds, with over $160 billion in tariff payments potentially due for refund to U.S. importers.
• Trump Considers Military Action Against Iran President Trump is considering a "limited military strike" against Iran aimed at forcing Tehran to agree to a new nuclear deal, with an opening assault possibly coming within days, according to the Wall Street Journal. Trump extended his timeline for a decision to "10-15 days, pretty much maximum," stating "We're either going to get a deal or it's going to be unfortunate for them." The U.S. has deployed two aircraft carriers to the Middle East—the USS Abraham Lincoln in the Arabian Sea and the USS Gerald R. Ford transiting from the Caribbean. British Prime Minister Keir Starmer has blocked U.S. requests to use UK airbases including Diego Garcia for strikes on Iran, citing international law concerns.
• Trump's Board of Peace Inaugural Meeting President Trump convened the first meeting of his newly created Board of Peace at the U.S. Institute of Peace, bringing together officials from nearly 50 countries. Trump announced the U.S. will pledge $10 billion to the organization, with member countries committing $7 billion for Gaza relief. The board aims to rebuild Gaza and establish an International Stabilization Force of 20,000 troops from Indonesia, Morocco, Kazakhstan, Kosovo, and Albania. Trump stated the board will "almost be looking over the United Nations." Several key allies including the U.K., France, and Canada declined to join.
• Former Prince Andrew Arrested in UK Prince Andrew Mountbatten-Windsor was arrested and held for 11 hours by British police on suspicion of misconduct in public office related to his ties with Jeffrey Epstein.

Police are investigating whether he shared confidential government documents with Epstein while serving as UK trade envoy. King Charles III issued a statement saying "the law must take its course."
• Norway Withdraws Troops from Middle East Norway relocated some of its approximately 60 military personnel stationed in Iraq and other parts of the Middle East back to Norway, citing security concerns amid heightened tensions between Iran and the United States.

Context: These diplomatic shifts underscore the complex interplay between security alliances, economic policy, and international conflict management.

💰 Economy & Markets

• Record U.S. trade deficit: Data show the U.S. posted an all-time high trade deficit of $1.24 trillion in goods in 2025, driven by imports significantly exceeding exports.

• Tariff ruling impacts: The Supreme Court’s decision to invalidate broad emergency tariffs signals a recalibration of U.S. trade posture, potentially easing inflationary pressures and encouraging multilateral negotiations with trading partners.

• IMF review ahead: The International Monetary Fund is set to release its annual assessment of U.S. economic policy late this week, likely addressing fiscal strategy, trade balance issues, and currency valuation.

• Reuters’ markets update says Wall Street opened lower on Friday after data showed U.S. growth slowed more than expected in Q4 and inflation picked up in December, before stocks then rose as investors digested the Supreme Court’s anti‑tariff ruling and its potential to ease trade frictions.​

• Nasdaq and Barchart this week have highlighted that AI‑related stocks and chipmakers remain highly volatile, with recent sessions swinging between sell‑offs on disruption fears and rallies when strong economic data or Big Tech announcements restore confidence.

• Nasdaq’s AI‑risk note says investors worry that huge AI capex might not generate matching profits and could cannibalize existing businesses, even as long‑term optimism about AI’s role in productivity and cloud infrastructure remains.

• Tariff Refund Chaos Expected The Supreme Court's ruling striking down IEEPA tariffs will spark a chaotic refund process, with over $160 billion potentially due to U.S. importers. President Trump fretted on social media that refunds "would be a complete mess, and almost impossible for our Country to pay." Treasury Secretary Scott Bessent said the federal government could issue refunds but questioned whether businesses like Costco would pass savings to consumers. California Governor Gavin Newsom called for immediate tariff refund checks.
• Economic Impact of Tariff Ruling According to the Yale Budget Lab, without IEEPA tariffs consumers face an overall average effective tariff rate of 9.1%—the highest since 1946 excluding 2025. The remaining tariffs will raise consumer prices by 0.6% in the short run, representing a loss of about $800 for the average household. The unemployment rate is estimated to be 0.3 percentage points higher by end of 2026. Had IEEPA tariffs remained, these impacts would have been approximately twice as large
