[Bank of America: the Federal Reserve may purchase $2 trillion of short-term treasury bond bonds within two years] Bank of America analysis said that the Federal Reserve may adjust its asset portfolio and purchase nearly $2 trillion of short-term treasury bond bonds in the next two years, almost covering the amount of bonds issued by the US Treasury Department in the same period. Bank of America strategists say that this move can optimize the Federal Reserve's asset liability structure, reduce interest rate and negative equity risks, and shorten the duration of liabilities. This demand matches a large number of short-term treasury bond issued by the Ministry of Finance due to the increase of the debt ceiling recently, injecting new demand into the market.
