China's rare earth export controls rattle markets as Trump threatens massive tariff retaliation
Oct 10, 2025
Key Points
- President Trump threatened massive tariff increases on Chinese products after China restricted rare earth exports, sending the S&P 500 down 70 points and signaling he will skip the APEC meeting with President Xi Jinping.
- Trump claims the U.S. holds stronger monopoly positions on critical materials than China but has refrained from weaponizing them until now, framing China's export controls as unprecedented hostility.
- Market traders view the escalation as part of a broader trade negotiation cycle, noting that similar tariff threats have historically led to reversal and that underlying business fundamentals can survive acute political uncertainty.
Summary
China's restriction on rare earth material exports triggered the first major market shock of the trade cycle. President Trump posted on Truth Social threatening massive tariff increases on Chinese products in response, sending the S&P 500 down 70 points. He described China's move as "sinister and hostile," noting that China has sent letters to countries worldwide demanding export controls on rare earth elements and related materials. Trump said he no longer sees reason to meet President Xi Jinping at APEC in South Korea, scheduled for two weeks out.
Trump argued that the U.S. holds stronger monopoly positions on critical materials than China does but has chosen not to use them until now. He signaled two immediate countermeasures: a massive increase in tariffs on Chinese products and additional unspecified sanctions under "serious consideration."
Traders noted the broader context. The S&P 500 reached a record high just days before this announcement. Similar trade escalations, including the earlier "Liberation Day" tariff threats, have historically been followed by negotiation and reversal. Base Power experienced severe near-term pressure over supply chain concerns during the previous tariff cycle but raised over $1 billion in an oversubscribed round shortly after, suggesting underlying business fundamentals can survive acute political uncertainty.
China's export controls are part of a broader trade negotiation where both sides signal leverage. The Journal reported yesterday that China's restrictions would disrupt global markets and give Beijing more leverage in talks. Trump's response confirms the administration views this as a trade war dynamic requiring immediate, forceful countermeasure, though the longer-term outcome remains uncertain.
