The interest rate on a U.S. Treasury bond, also known as the coupon rate, is fixed and does not adjust in response to changes in the Federal Reserve's target interest rate. Here's how it works:
- Fixed Coupon Rate: When you buy a U.S. Treasury bond, the coupon rate is already determined and is part of the bond's terms. This rate is fixed and does not change over the life of the bond.
- Monetary Policy Impact: When the Federal Reserve lowers its target interest rate, it affects short-term interest rates, such as the federal funds rate. However, this does not directly impact the coupon rate of a Treasury bond.
- Bond Price Movement: What might happen is that the market demand for bonds might change due to the expectation of lower interest rates. This can cause the price of existing bonds to increase, as investors seek higher returns elsewhere. However, this increase in price does not alter the coupon rate of the bond.
- Yield Adjustment: The yield on a Treasury bond can adjust over time based on various factors, including changes in interest rates. The yield is the return an investor realizes on the bond and is influenced by the risk-free rate of return, which can be affected by monetary policy. When interest rates are low, bond prices increase, and yields decrease, and vice versa1.
- Investment Consideration: If you're considering buying a Treasury bond and expecting a certain type of return based on future interest rate changes, it's important to understand that the bond's coupon rate will remain fixed. You should evaluate the bond based on its current yield, the time until maturity, and the creditworthiness of the issuer, rather than future interest rate expectations.
In summary, the interest rate on a U.S. Treasury bond you buy is fixed and does not adjust in response to the Fed's rate changes. The bond's price might fluctuate based on market conditions and interest rate expectations, but the coupon rate itself will remain unchanged.
