Book. The $13 Trillion Question. Managing the U.S. Government’s Debt (David Wessel, Brookings)

Everyone talks about the size of the U.S. national debt: now at $13 trillion and climbing, but few talk about how the U.S. Treasury does the borrowing—even though it is one of the world’s largest borrowers. Everyone from bond traders to the home-buying public is affected by the Treasury’s decisions about whether to borrow short or long term and what types of bonds to sell to investors.
