Corporate FRNs vs T-Bills: An Investor’s Guide

09 February 2026

Read Time 3 MIN

Corporate FRNs pay floating coupons tied to short-term rates plus a credit spread, offering higher yields with minimal interest rate sensitivity. T-bills are short, zero-coupon Treasuries.

Key Takeaways:

  • Corporate FRNs offer yield that resets with short-term rates.
  • T-bills are the safest short-term cash with zero-coupon Treasuries with high liquidity and minimal credit risk.

What Is a Floating Rate Note (FRN)?

A corporate floating rate note (FRN) pays a coupon which resets periodically based on a short-term reference rate (typically SOFR) plus a fixed credit spread, causing income to rise when short-term rates increase and decline when rates fall. Because these coupons adjust regularly, FRNs prices have minimal sensitivity to interest rate movements, unlike fixed-rate bonds, making income the primary source of returns over time.

Who Should Invest in FRNs?

Corporate floating rate notes may be appropriate for investors seeking an enhanced yield versus risk-free rates with minimal interest-rate risk. Because FRN coupons reset with prevailing reference rates, they can be particularly useful in environments where rates are elevated, volatile, or uncertain, and where traditional fixed-rate bonds face price pressure from rising yields.

FRNs can also function as a cash complement for investors with intermediate holding periods who are willing to accept modest volatility in exchange for higher income potential than money market instruments or Treasury bills. While corporate FRN prices tend to be stable due to low duration, returns are still influenced by credit spreads, meaning short-term volatility is possible during periods of market stress.

What Is a T-Bill?

Treasury bills (T-bills) are short-term U.S. government securities issued with maturities from a few days up to 52 weeks. T-bills are sold at a discount to par and pay par at maturity, they are zero-coupon instruments.

Who Should Invest in T-Bills?

Investors needing the safest, most liquid cash alternative, or a short-term parking place for capital should consider investing in T-bills.

When to Invest in FRNs vs T-Bills

Corporate FRNs and T-bills both serve as short-term building blocks, but they solve different investor problems: FRNs are a yield-seeking, low-duration solution with minimal credit exposure; T-bills are the safety-first, ultra-liquid, government alternative. The right choice depends on your objectives, safety and liquidity vs. income with minimal credit risk.

  • Use FRNs when you want to harvest higher income vs risk free rates in environments where short-term rates are elevated or expected to rise, but you want to avoid the duration losses of fixed-rate bonds. FRNs are appropriate when you accept issuer credit risk in exchange for spread-based yield.
  • Use T-Bills when capital preservation, minimal credit risk, and liquidity are the primary objectives. T-bills are the default cash instrument for short-term liquidity, regulatory or collateral use, and conservative cash allocations.
