Detailed Summary
Trump's Tariffs Before the Supreme Court
The US Supreme Court will potentially decide today (January 9, 2026) on the constitutionality of President Trump's tariffs. The IEPA authority (International Emergency Economic Powers Act) forms the legal basis for these tariffs, which were introduced in April 2025.
Multiple lawsuits argue that the President does not have the authority to rely on this 1977 emergency statute. Lower courts have already ruled in favor of the plaintiffs. The collected tariffs have so far generated approximately 150 billion dollars for the US Treasury – total volume around 200 billion dollars. A loss for the Trump Administration would result in refund obligations on this scale.
Trade adviser Peter Navarro expressed confidence that the government could quickly reimplements the tariffs under alternative legal grounds (Section 232, Section 301). These authorities are already being used for steel, aluminum, automotive, and China tariffs.
Iran: Internet Blackout During Escalating Protests
Iran has cut off telephone and internet services as massive protests in the capital Tehran have escalated. According to unverified social media videos, thousands have taken to the streets.
The unrest began on December 28 in Tehran's Grand Bazaar, triggered by the rapid devaluation of the Iranian currency. The protests are being interpreted as a direct challenge to Supreme Leader Ayatollah Ali Khamenei. According to the Human Rights News Agency, 42 people have already been killed in security force operations.
US President Trump announced he would judge the regime and threatened a "very hard" response should Iranian authorities crack down on protesters.
Greenland Payments and Transatlantic Tensions
The USA is considering payments of up to $100,000 per capita to Greenlanders to promote Greenland's separation from Denmark. US Vice President J.D. Vance confirmed that the Trump Administration is prepared to go "as far as necessary" to protect US interests.
French President Emmanuel Macron sharply criticized these plans. At the Élysée ambassadors conference, he warned against increasing fragmentation of the international order and characterized the USA as a power that is slowly distancing itself from alliances and international rules.
Other Markets and Trends
Copper Market: Rio Tinto is conducting merger negotiations with BHP. A merger would create the world's largest mining company with a market value over 200 billion dollars. Copper has reached record highs above $13,000 per ton.
China: Inflation is accelerating to the fastest rate in three years (0.8% YoY), driven by food prices. Producer prices fell for the 39th consecutive month by 2.1%.
United Kingdom: Unemployment has reached a three-year high. The number of potential layoffs is at the second-highest level since the pandemic, increasing pressure on the Bank of England to cut interest rates.
Tech Trend: Microsoft CEO Satya Nadella launches a personal blog with minimalist design without filters – a symbol of a new trend of "visionary technology leaders without censorship".
