Roll-Down in Pure Floaters and Margin-Bearing FRNs

Summary

The document asks whether floating rate notes have no roll-down over a given horizon because they are relatively insulated from interest rate risk. The response distinguishes pure floaters from notes that pay a margin over the reference rate. For a pure floater with no margin, it agrees that roll-down is absent; when a margin is present, that component may roll down as the note approaches maturity.

This is a brief qualitative explanation rather than a pricing derivation or empirical analysis. It offers no assumptions about the reference rate, reset frequency, credit spread, or market discount curve, all of which can affect an FRN’s observed price and yield. The distinction is useful as a starting point: rate resets limit exposure to changes in the benchmark rate, while a contractual margin can contribute a maturity-related price effect.

Key ideas

• A pure floater with no margin is described as having no roll-down.
• An FRN’s benchmark-rate resets help limit its interest rate exposure.
• A margin-bearing note may experience roll-down as it approaches maturity.
• The response gives a qualitative distinction rather than a detailed valuation framework.

is it correct to say that floating rate notes (FRNs) have no roll-down for a time horizon as it is interest risk free?

This is correct for pure floaters; that is, bond that have no margin. If there is margin, it likely rolls down as the bond approaches maturity
