US President Donald Trump’s announcement of 100% tariffs on China sent shockwaves through global stock markets. The decision came after Beijing announced new export controls on strategic minerals that have dual-use in military applications, framing the measures as necessary for national security and compliance with international obligations.
Trump, who returned to the political spotlight with his post on Truth Social, framed China’s actions as “extremely hostile” and “unprecedented”, vowing to impose tariffs that would surpass any existing duties. According to his statement, these measures would affect all countries, with Washington also imposing export controls on critical software starting the same day.
The Trump administration’s stance has raised concerns among investors, given that the announcement has triggered widespread market volatility. The S&P 500 fell by nearly 2.7%, marking its largest single-day loss since April, while the Dow Jones Industrial Average dropped nearly 900 points, or 1.9%. The tech-heavy Nasdaq plunged 3.6% as investors sought safety in lower-risk assets, signaling fear over the potential disruption to global supply chains.
A recent trade truce between the U.S. and China, which had seen tariffs on Chinese goods drop from 145% to 30%, is set to expire in November, adding to the uncertainty over future trade relations. Analysts warn that the full impact of Trump’s announcement will depend on how China and other trading partners respond, potentially reshaping global economic dynamics in the coming months.
