Internet reported that on Friday, U.S. Treasury yields soared to their highest level since February this year. Traders complain that liquidity is deteriorating as the $29 trillion U.S. Treasury market slump intensifies. The U.S. 10-year Treasury yield climbed 0.19% to 4.58%. Treasury bonds, traditionally regarded as the ultimate safe haven for the global financial system, are slipping into a deeper downturn. Earlier this week, U.S. Treasury yields were less than 3.9%, but Trump's erratic tariff policy shook investors 'confidence in U.S. policymaking and the economy, triggering a flood of investors fleeing U.S. assets. "If you are a foreign holder, there is real pressure to sell U.S. Treasurys and corporate bonds globally," said Peter Tchir, head of U.S. macro strategy at Academy Securities. "What the world is really worried about is that they don't know what Trump is going to do." Friday's sell-off led to the worst week for U.S. Treasuries since 2019, and was accompanied by a fall in the dollar, based on returns from the Bloomberg Treasury Index. "We are concerned because the trend you are seeing suggests that this is not a normal sell-off," said a senior executive in the bulk services division of a European bank. "They show a complete loss of confidence in the world's strongest bond market."
