Odaily Planet Daily - Deutsche Bank said that if the turbulence that once pushed the long-term borrowing cost of the United States to more than 5% continues, the Federal Reserve will need to act to stabilize the U.S. treasury bond market. On Wednesday, due to Trump's tariff war, doubts about the security of US assets continued to escalate, intensifying the selling of US treasury bond bonds. The yield of 30-year treasury bond rose to 5.02%, the highest level since November 2023. If this situation continues, the Federal Reserve will need to intervene, which the bank's global head of foreign exchange strategy, George Saraveros, calls the "circuit breaker mechanism" - emergency quantitative easing. He wrote: "If the recent turmoil in the US treasury bond bond market continues, we believe that the Federal Reserve has no choice but to urgently purchase US treasury bond bonds to stabilize the bond market."
