Former Treasury Secretary Steven Mnuchin has called for the discontinuation of the 20-year Treasury bond, which he reintroduced in 2020, citing its higher yields and additional costs to taxpayers. The bond’s reintroduction has resulted in approximately $2 billion in extra annual interest expenses, totaling around $40 billion over its lifespan. Despite the Biden administration’s preference for maintaining the bond to ensure stability, Mnuchin argues that the bond has not met expectations and is financially burdensome. The debate over the bond highlights the complexities of managing the U.S. government’s growing deficit.
