币界网报道：Former U.S. President Donald Trump's recent policy proposals have triggered significant market turbulence, with the Japanese yen surging 9% against the dollar—its biggest single-day gain since 1998—while the U.S. dollar index dropped 7%. The tech-heavy Nasdaq Composite plummeted by 7%, erasing $7 trillion in market value, as Trump floated aggressive trade tariffs and restrictions on Chinese tech imports. Analysts warn these protectionist measures could disrupt global supply chains, particularly in semiconductors, where China accounts for 15% of U.S. chip purchases. The proposals also include banning U.S. investments in Chinese AI and quantum computing firms, potentially impacting $50 billion in annual tech sector cross-border investments. Meanwhile, Bitcoin briefly spiked 12% as investors sought alternative assets, before settling at a 5% gain. Treasury yields fell sharply, with the 10-year note dropping 25 basis points to 4.15%, as traders priced in slower economic growth. Asian markets reacted strongly, with Hong Kong's Hang Seng Index closing down 8%—its worst day since the 2008 financial crisis. The ripple effects extended to commodities, where copper prices dropped 6% on reduced demand expectations. Market volatility indices hit 18-month highs, with the VIX jumping to 32. Some economists estimate the proposed policies could shave 0.8% off global GDP growth if implemented. Corporate leaders expressed alarm, with several Fortune 500 CEOs reportedly holding emergency calls to assess supply chain vulnerabilities. The White House declined to comment on the market reaction, while Treasury Secretary Janet Yellen emphasized the need for "measured economic policies." Investors are now pricing in a 60% chance of Fed rate cuts by September to counteract potential economic slowdown.
