Overview
A Variable-Rate Security is a type of financial instrument in which the interest rate is not fixed but instead fluctuates in response to market interest rates. Examples include floating-rate notes, eurobonds, and 90-day certificates of deposit.
Historical Context
The concept of variable-rate securities emerged in response to the volatility of interest rates, allowing issuers and investors to mitigate interest rate risk. These securities became more prevalent with the development of financial markets and advanced economic models that could predict and adjust for market conditions.
Types of Variable-Rate Securities
1. Floating-Rate Notes (FRNs)
These are bonds with interest payments that adjust periodically, usually every three to six months, based on a specified benchmark such as the London Interbank Offered Rate (LIBOR).
2. Eurobonds
Issued in a currency different from the issuer’s home country, Eurobonds can have variable interest rates tied to benchmarks like LIBOR or the Euro Interbank Offered Rate (EURIBOR).
3. 90-Day Certificates of Deposit (CDs)
These short-term, negotiable deposits offer interest rates that reset periodically, making them an attractive option in fluctuating interest rate environments.
Key Events
- 1980s: The popularization of floating-rate notes as a response to high volatility in interest rates during this decade.
- 1990s: Eurobonds gained popularity, offering diverse currency exposure and variable interest rates.
- 2000s and beyond: Advanced financial instruments like collateralized loan obligations (CLOs) began incorporating variable-rate features.
Detailed Explanations
Variable-rate securities are structured to adjust their interest payouts at predetermined intervals according to a predefined index or benchmark. This mechanism helps both issuers and investors manage the uncertainties associated with interest rate movements.
Mathematical Models/Formulas
Interest Rate Adjustment Formula
The interest rate for variable-rate securities is often expressed as:
- Benchmark Rate is the reference interest rate such as LIBOR.
- Margin is the fixed amount added to the benchmark rate to determine the total interest rate.

Importance and Applicability
Variable-rate securities play a crucial role in both investment portfolios and risk management strategies. They offer a hedge against rising interest rates, making them suitable for investors seeking to protect their investments from interest rate risk.
Examples
- An investor holding a floating-rate note tied to LIBOR benefits when market interest rates rise, as the interest payouts increase.
- Companies issue variable-rate securities to attract investors looking for protection against interest rate volatility.
Considerations
Investors should consider the potential for interest rate fluctuations and the specific benchmarks tied to the securities. It’s essential to evaluate the margin added to the benchmark rate, as this can impact the overall return.
