U.S. Treasury yields fell across the board by at least 3 basis points on Thursday, with the 30-year yield hitting 5.38%, its lowest level since September 23. Global capital clearly flowed into traditional safe-haven assets, with the Japanese Yen appreciating 0.3% against the U.S. Dollar to 157.68, and the Swiss Franc also rising 0.2%. Market sentiment turned fragile as investors' doubts grew regarding the profitability and return on investment of AI-related assets, triggering a stock market decline and activating safe-haven demand for government bonds.
