Trump's verbal attacks are causing trouble again. Is global capital beginning to "abandon the United States" collectively?

As concerns grow about U.S. President Donald Trump potentially fulfilling his threat to dismiss Federal Reserve Chair Powell and implement policies that could lead to an economic recession, a wave of "selling U.S. assets" is unfolding. Data shows the S&P 500 index plummeted 2.7% on Monday to 5,142.18 points, down 13% year-to-date and 16% from recent highs; the Dow Jones Industrial Average dropped 972 points, a 2.5% decline; the Nasdaq Composite fell deeper into bear market territory, down 21% from its peak. The bond market is equally pessimistic, with 10-year U.S. Treasury yields rising 7 basis points to 4.41% and 30-year yields jumping 10 basis points to 4.91%. In the currency market, the U.S. Dollar Index fell 0.9%, depreciating over 5% against the euro and yen, hitting a three-year low. Investors are struggling with the risk of Powell potentially being dismissed (the White House indicated last week it was evaluating this) and Trump's policies' potential impact on the world's largest economy. They are withdrawing from U.S. safe-haven assets, and broader risk-off sentiment has driven gold to a historic high on Monday, with cryptocurrencies also rising, with Bitcoin touching $88,000 for the first time since March.
