Global Markets Hit by Fierce Trade Turmoil (Oct 2025)

President Donald Trump just made headlines again—this time with a strong warning to China. In a post on Truth Social, he accused China of taking hostile trade actions and said the U.S. might respond with major tariff hikes on Chinese imports.

That’s because China is planning to tighten export controls on rare earth elements and other key materials used in global manufacturing. These controls could affect not just Chinese-made products, but also supply chains around the world. Trump called this move “unprecedented and destructive”, saying it could seriously disrupt international trade.

He also claimed that many countries are angry about China’s decision and see it as a sign of economic aggression. Trump added that China has been trying to keep the world dependent by controlling rare metals and magnets, but the U.S. has powerful tools too, and won’t hesitate to use them.

As a result, Trump canceled his upcoming meeting with China’s President at the APEC summit, calling China’s timing “deliberate and strategic.” He ended his message by saying that while the U.S. response might be tough in the short term, it will ultimately help both America and the global free market.

Impacts of This News on Markets

Trump’s warning and China’s export controls have already started to rattle global markets.

The S&P 500 (SPX) fell more than 2.5%, as investors grew anxious about the potential fallout from escalating trade tensions. Concerns over disrupted supply chains, rising costs, and geopolitical uncertainty triggered a broad sell-off, especially in sectors like technology, manufacturing, and consumer goods, which rely heavily on Chinese imports and rare earth materials. As a result, Nasdaq (NDX) fell more than 3%.

Trump’s tariff warning and China’s rare earth restrictions aren’t just shaking up U.S. markets; they’re sending ripples across the globe.

  • Stock indexes in the U.S., Europe, and Asia fell 1.2–2.5%.
  • Rare earth prices surged, especially neodymium and dysprosium, used in EVs, wind turbines, and defense tech.
  • Oil prices dipped as fears of slower global growth outweighed supply concerns.
  • Currency volatility increased.
