Capped Floating-Rate Note

August 31, 2024 Fixed Income

A capped floating-rate note has a variable coupon with a maximum rate, limiting income upside when benchmark rates rise.

On this page

A capped floating-rate note is a floating-rate note whose coupon resets by formula but cannot exceed a stated maximum rate. The cap can make the note cheaper for the issuer or more predictable at high rates, but it limits the investor’s income upside.

Key Takeaways

  • The cap is an embedded limit on the coupon, not a guarantee of principal or liquidity.
  • A capped FRN usually pays the lower of the uncapped floating rate and the stated cap.
  • The cap matters most when the reference rate plus spread rises above the maximum coupon.
  • Investors still need to review credit quality, call provisions, liquidity, tax treatment, benchmark fallback, and any floor or collar.

Coupon Formula

$$ \text{Coupon Rate} = \min(\text{Reference Rate} + \text{Spread},\ \text{Cap}) $$

If a note pays SOFR plus 1.00% with a 6.00% cap, and the reference rate is 5.50%, the uncapped coupon would be 6.50%. The investor receives 6.00% for that period because the cap applies.

Why It Matters

A capped FRN can look attractive when the current coupon is near a comparable floating-rate note. The cap becomes important when rates rise: the investor may stop participating in further coupon increases while still bearing issuer credit and secondary-market risk.

Common Mistakes

  • Comparing only today’s coupon and ignoring the cap.
  • Treating a cap as downside protection for the investor.
  • Ignoring whether the note also has a floor, collar, call feature, or step-up cap.
  • Assuming the note will trade at par before maturity.
  • Forgetting that the cap can reduce value when market rates rise above it.

FAQs

Who benefits from the cap on a capped FRN?

The cap usually benefits the issuer when rates rise above the cap because it limits the coupon the issuer must pay. The investor accepts limited upside in exchange for the note’s stated terms.

Can a capped floating-rate note lose value?

Yes. A capped FRN can lose value because of issuer credit deterioration, liquidity problems, call features, benchmark changes, or because the cap makes the coupon less attractive when market rates rise.
