In March, the FOMC decided to trim its reduction of U.S. Treasury security holdings. For months, the Fed reduced those positions by $25 billion per month. Beginning in April, it will only reduce Treasury holdings by $5 billion monthly. “With the Fed tempering quantitative tightening, it may put a little less pressure on Treasuries, but the Fed is maintaining a lot of pressure on mortgage rates.” The Fed continues monthly $35 billion reductions in its mortgage-backed securities holdings, which total more than $2 trillion.
Congressional actions may also affect fixed income markets. In early 2025, the federal government reached its debt ceiling limit, meaning no new debt is being issued. Instead, the Treasury Department is pursuing “extraordinary measures” to maintain government operations. This includes spending down much of the $800 million the Treasury holds in general account funds. “This likely contributed to the recent interest rate decline,” says Haworth. “The Treasury can’t issue debt due to the debt ceiling, and they are adding liquidity to the market, leading investors to put more money to work in Treasuries.” That created a more favorable supply-demand balance, reducing bond yields.
In the coming months, Congress must address the debt ceiling issue. Once Congressional action again suspends the debt ceiling, new Treasury debt can be issued, boosting supply. “The effect could be to reverse the whole process, and the temporary circumstances helping bond yields decline would no longer exist,” says Haworth. However, bond yield trends are driven by a variety of market forces.
Today’s flat yield curve
Early 2025’s decline in long-term yields occurred as short-term rates remained relatively stable. This comes in the wake of the Federal Reserve’s (Fed’s) most recent interest rate stance, holding the line on the short-term fed funds rate. In recent weeks, the 3-month Treasury yield held near 4.35%. In early March, the 10-year Treasury yield dropped to 4.22%. As a result, the yield curve again modestly inverted, but not as dramatically as was the case from late 2022 until late 2024. Today’s yield curve, the yield generated by Treasury bills from 3-month maturities to 30-year maturities, is virtually flat. “This reflects that for the time being, the Fed’s interest rate moves lag the market’s earlier expectations,” says Haworth.
