Discount Margin Essential Guide for Bond Investors

1512 reads · Last updated: January 11, 2026

Discount Margin refers to the difference between the yield of a floating-rate bond and a benchmark interest rate (such as Libor or Treasury yield). Specifically, the discount margin is the additional yield that investors expect to receive over the benchmark rate while holding a floating-rate bond. This margin is typically determined by calculating the difference between the present value of the bond and the discounted value of its future cash flows. The discount margin helps investors assess the attractiveness and risk level of floating-rate bonds.
