Strategy Does a Stretch

The article differentiates between fixed and floating-rate bonds concerning interest rate risk. Fixed-rate bonds experience principal value depreciation when prevailing interest rates rise, as their fixed coupon becomes less attractive, necessitating a price drop to align their yield with market rates. In contrast, floating-rate bonds, such as those indexed to SOFR, largely mitigate this risk by adjusting their coupon payments upwards with rising rates, thereby preserving their principal value and offering stability in a volatile interest rate environment.

Analysis

The provided text offers a fundamental explanation of interest rate risk by contrasting fixed-rate and floating-rate bonds. It illustrates that fixed-rate instruments exhibit an inverse price-to-yield relationship; a hypothetical five-year bond with an 8% coupon would see its market value decline from $100 to $96 if prevailing interest rates rise by one percentage point. This price depreciation is necessary to align the bond's effective yield with the new, higher market rates. Conversely, floating-rate bonds, particularly those indexed to a benchmark like the Secured Overnight Financing Rate (SOFR), are presented as a tool to mitigate this risk. By design, the coupon on a floating-rate bond adjusts in tandem with its underlying benchmark. For instance, a bond paying SOFR plus 4% will offer a higher nominal payout if SOFR increases, thereby preserving its principal value around $100. This dynamic makes floating-rate debt a more stable asset in a rising or volatile interest rate environment, shifting the primary risk consideration from interest rate sensitivity to the issuer's credit quality, which is reflected in the spread over the benchmark rate.

Key Decisions for Investors

• In an environment of rising or volatile interest rates, investors should assess their portfolio's duration risk, as existing fixed-rate bond holdings are susceptible to principal depreciation.
• Consider allocating to floating-rate notes (FRNs) or other instruments benchmarked to rates like SOFR to hedge against interest rate risk and enhance capital preservation.
• While floating-rate bonds mitigate interest-rate risk, the credit spread over the benchmark rate remains a key indicator of issuer risk and must be a central part of the investment due diligence process.
