[The Federal Reserve Will Roll Over Maturing Treasury Principal Starting in December] In its latest Federal Open Market Committee (FOMC) statement, the Federal Reserve announced that starting December 1, 2025, it will roll over (reinvest) the principal of all maturing U.S. Treasury securities. This policy means the Federal Reserve will reinvest the principal of maturing Treasuries into newly issued U.S. Treasury securities, thereby maintaining the size of its balance sheet. This move is typically interpreted as a signal of a shift toward monetary policy easing or the end of a tightening cycle.
