The bond market is skeptical of the plan of US Treasury Secretary Besant to deal with US $40 trillion of US treasury bond. Besant announced its plan to increase the repurchase scale of long-term treasury bond bonds and promised to use its toolbox to support the market. John Arnold stated that the lack of change in the US fiscal situation will continue until a crisis is triggered. Tracy Chen said that Besant failed to curb the yield of long-term treasury bond bonds, and the bond vigilantes still distrusted Besant. Besant needs to take more action to persuade investors to prove that the Trump administration is taking US fiscal issues seriously.
