Guide to Floating-Rate Bonds: Definition, Working Mechanism & Investor Benefits

In an era of fluctuating interest rates, floating-rate bonds have emerged as an attractive investment avenue for investors seeking both flexibility and stable returns. Unlike traditional fixed-rate bonds, floating-rate bonds adjust their interest payouts periodically, helping investors capitalise on interest rate changes while protecting their capital from rate volatility.

In this guide, we explore the definition, features, benefits, and strategies for investing in floating-rate bonds in India, along with real-life examples.

Key Takeaways

  • Floating-rate bonds have variable interest rates linked to benchmark rates, which reset periodically.
  • They offer protection against rising interest rates, as coupon payments increase when benchmark rates rise.
  • Prices of floating-rate bonds remain more stable than fixed-rate bonds since interest payments adjust with market rates.
  • Benefits include interest rate hedging, low price volatility, portfolio diversification, and potential for higher returns.
  • Investors can optimise returns by analysing yield curves, actively managing portfolios, and diversifying across issuers.

What are Floating-Rate Bonds?

Floating-rate bonds (FRBs) are debt instruments whose coupon rates are linked to a benchmark interest rate, such as the repo rate, reverse repo rate, or T-bill rates in India, or globally, the LIBOR or Federal Funds Rate.

Whenever the benchmark rate changes, the bond’s coupon payments adjust according to a predefined formula. Issuers of floating-rate bonds include governments, banks, and large corporations, with interest payments typically made quarterly, semi-annually, or annually.

Think of it like a floating-rate home loan: as the repo rate rises, the EMIs increase. Similarly, investors in FRBs receive higher interest payments when benchmark rates rise, providing a hedge against inflation and interest rate risk.

How Do Floating Rate Bonds Work?

Floating-rate bonds make interest payments at regular intervals and repay the principal amount at maturity. However, the interest rate is not fixed. It increases or decreases based on changes in the linked benchmark rate. These changes are passed on to the bond’s coupon rate on pre-set dates.

For example, consider a floating-rate bond with a face value of ₹1,00,000 that is linked to a benchmark rate, such as the central bank policy rate, with a spread of 1.5%. Assume that the bond pays interest every six months and resets its rate at the beginning of each period.

At the time of issuance, if the benchmark rate is 6%, the coupon rate for the first six months would be 7.5% (6% + 1.5%). The investor would therefore receive interest based on this rate for that period.

At the next reset date, suppose the benchmark rate rises to 7%. The coupon rate for the following six months would adjust to 8.5%. As a result, the interest payment for that period would be higher. If, in a later period, the benchmark rate falls to 5.5%, the coupon rate would decrease to 7%, leading to a lower interest payment.

This adjustment continues throughout the life of the bond, depending on movements in the benchmark rate. At maturity, regardless of these fluctuations in interest payments, the investor receives the original principal amount of ₹1,00,000.

Since the rate is reset periodically, it tends to stay aligned with prevailing market rates. This structure helps reduce interest rate risk, especially during periods of rising interest rates.

Features of Floating Rate Bonds

The following are some key features of floating rate bonds:

  • Minimum Investment Amount: Individuals can start investing, typically from a minimum of ₹1,000 and in multiples thereafter.
  • Maximum Investment Amount: There is generally no upper limit, allowing flexibility in investment size.
  • Bond Tenure: These bonds usually have a fixed maturity period, often around 7 years.
  • Interest Payments: Interest is commonly paid semi-annually, for example, on 1st January and 1st July.
  • Eligibility Criteria: Resident individuals and Hindu Undivided Families (HUFs) are usually eligible, while NRIs may not be allowed.
  • Interest Rate Structure: The rate is linked to a benchmark such as NSC, along with a fixed spread.
  • Withdrawal: Premature withdrawal is generally restricted, with limited exceptions for senior citizens under specific conditions.
  • Collateral: These bonds are generally not accepted as collateral for loans.

Types of Floating Rate Bonds Available in India

Floating-rate bonds in India can be broadly categorised based on the issuer and structure:

1. Government Floating Rate Bonds

These are issued by the government, such as RBI floating-rate savings bonds. They are generally considered more stable due to sovereign backing.

2. Corporate Floating Rate Bonds

Issued by companies and financial institutions, these bonds may offer different return profiles depending on the issuer’s credit quality.

3. Market-Linked Floating Bonds

These bonds are linked to market benchmarks such as treasury yields or other interest rate indicators, reflecting broader market conditions.

Mechanics of Floating-Rate Bonds

Floating-rate bonds have three key components:

1. Coupon Rate:

The interest rate on FRBs is tied to a benchmark rate plus a fixed spread. In India, it could be linked to NSC, repo rate, or T-bills, while globally it may track LIBOR or US Treasury rates.

2. Coupon Reset:

Interest rates are periodically reset (quarterly or semi-annually) based on market benchmarks, allowing investors to capture rate changes over time.

3. Interest Payments:

Payments are calculated by applying the reset coupon rate to the bond’s principal. For example, a bond with a principal of INR 100,000 and a 7% floating coupon will pay INR 3,500 semi-annually if the rate is 7%.

Example: RBI Floating-Rate Bond

The RBI’s floating-rate bonds are linked to the National Savings Certificate (NSC) rate plus 0.35% spread. Suppose an individual invest INR 100,000 in July 2020 with semi-annual interest payments.

  • Jan–Jun 2023: NSC rate change results in INR 3,675 per 6 months
  • Jul–Dec 2023: Coupon rises to INR 4,025 per 6 months

This example shows how interest payments fluctuate in sync with benchmark rates, providing an effective hedge against interest rate changes.

Taxation of RBI Floating Rate Bonds

Taxation is an important aspect to consider before investing in these bonds:

  • Interest income is taxed as per the investor’s income tax slab
  • Capital gains for a holding period of less than one year are taxed as per slab rates
  • Capital gains for a holding period above one year are taxed at 12.5% without indexation

Benefits of Investing in Floating-Rate Bonds

Hedge Against Rising Rates:

FRBs adjust with market rates, protecting investors from the adverse effects of interest rate hikes.

Low Price Volatility:

Since coupon rates reset periodically, FRBs maintain stable market prices compared to fixed-rate bonds.

Credit Safety:

Issued by governments and high-creditworthy institutions, FRBs generally carry low default risk.

Potential for Higher Returns:

Investors benefit when interest rates trend upward, capturing better yields than fixed-rate bonds.

Portfolio Diversification:

FRBs provide an alternative fixed-income asset, balancing equity and fixed deposits in a diversified portfolio.

Limitations of Floating Rate Bonds

The limitations of investing in floating-rate bonds are as follows:

  • Lower Yield: Floating-rate bonds may offer lower overall returns compared to fixed-rate bonds.
  • Uncertainty of Income: The interest income is not constant and may vary over time due to periodic changes in the benchmark rate.
  • Interest Rate Risk: Since the coupon rate is not fixed, returns may decrease when interest rates fall. This can lead to lower income compared to fixed-rate bonds.

Factors Affecting the RBI Floating Bonds Interest Rate

Factors that can affect the interest rate of RBI floating rate bonds include:

  • Inflation Trends: Changes in inflation affect the benchmark interest rate in the economy. When inflation rises, benchmark rates increase, leading to higher interest rates on bonds. However, benchmark rates decrease when inflation reduces. So, the bond’s interest rate also decrease.
  • Economic Trends: Economic trends can play a major role in the change in interest rates and benchmarks linked to these bonds.
  • Repo Rate Changes: The repo rate set by the RBI can play a major part in determining the interest rates. Hence indirectly affecting the interest rates of floating-rate bonds.


How to Invest?

Investing in floating-rate bonds generally involves the following steps:

  • Select a suitable platform, like a nationalised bank, private bank, or the RBI Retail Direct platform
  • Access the bond investment section
  • Fill in the required details and select the investment amount
  • Submit the necessary documents, such as PAN and address proof
