What are Fixed Income ETFs: A Complete Guide for Retail Investors

Fixed income ETFs have gained popularity among investors looking for consistent income, portfolio diversification, and a convenient tool to invest in bonds. But what exactly are fixed income ETFs? How do they operate?

In essence, a fixed income ETF is a collection of bonds traded on a stock exchange in a similar way to stocks. Investors can buy units of an ETF without having to invest separately in individual bonds.

Investing in fixed income ETFs might be an attractive option for some investors. However, it is important to understand that such funds are not risk-free. Their prices fluctuate and may be affected by various factors, including interest rates and market conditions. 

This article explains what fixed income ETFs are, their benefits, risks, and more.

Key Takeaways

• Fixed income ETFs provide access to a basket of bonds through one investment. They can make bond investing simpler and more diversified.
• The price of ETFs can rise and fall depending on interest rates, credit conditions, and market movements.
• Bond prices generally fall when interest rates rise and increase when rates fall, with longer-duration bonds usually being more sensitive.
• Investors should note that different fixed income ETFs have different risk levels.
• One should look at expense, credit quality, duration, maturity, liquidity, and the fund's investment strategy when choosing an ETF.

What are Fixed Income ETFs?

Fixed income ETFs are exchange-traded funds that primarily invest in fixed income instruments like government bonds, corporate bonds, municipal bonds, treasury securities, or any other form of debt instrument.

The ETF collects money from various investors who pool their funds into a security portfolio. The ETF will then issue units that can be purchased by investors through the stock exchange in the trading period.

For instance, let us take an ETF that holds numerous government and corporate bonds. Instead of buying the bonds individually, an investor can simply purchase one unit in the ETF and gain exposure to the entire portfolio.

How do Fixed Income ETFs Work?

• Yield to Maturity (YTM), Not Fixed Interest: Fixed-income ETFs do not pay fixed FD-like interest rates. Instead, the expected annualized return for an investor who holds the fund for a specific duration is driven by the portfolio's Yield to Maturity (YTM) after accounting for expense ratios.
• Income Distribution: The underlying bonds earn interest (coupons). The fund collects this interest and either periodically distributes dividends to investors or reinvests it, depending on the specific scheme's policy.
• Intraday Trading & Indicative NAV (iNAV): Because they trade on exchanges, you can buy or sell units during market hours. To ensure you aren't overpaying or selling at a loss due to market maker spreads, investors should check the Indicative NAV (iNAV), a real-time estimate of the ETF's net asset value published during trading hours, to verify whether the ETF is trading at a fair price, premium, or discount relative to its underlying bond portfolio.

Understanding Duration & Interest Rate Sensitivity

The market price of a fixed-income ETF fluctuates based on prevailing interest rate movements in the economy. Bond prices generally fall when interest rates rise and increase when interest rates fall.

What is Duration?

Duration measures a bond fund's price sensitivity to interest rate changes.

The Rule of Thumb:

If an ETF has a duration of 5 years, a 1% rise in interest rates decreases its market price by approximately 5% (and vice versa). Longer-duration funds carry higher interest rate risk, whereas short-term or liquid ETFs remain relatively stable.

Types of Fixed Income ETFs

Unlike Western markets, the Indian fixed-income ETF ecosystem is tailored around specific domestic debt instruments (excluding municipal bonds, which lack retail liquidity in India):

• G-Sec & T-Bill ETFs: Hold sovereign debt issued by the Government of India. Government Securities (G-Secs) provide long-term lending exposure with near-zero default risk, while Treasury Bills (T-Bills) offer ultra-short-term sovereign backing. 
• Corporate Bond ETFs: Hold high-quality debt issued by public and private sector corporations, offering higher yields than government debt in exchange for slight credit risk.
• State Development Loans (SDL) ETFs: Invest in bonds issued by various Indian state governments, providing a sovereign-backed yield often slightly higher than central G-Secs.
• Target Maturity ETFs (e.g., Bharat Bond ETF, SDL ETFs): The cornerstone of Indian fixed-income ETFs. They have a pre-defined maturity date. As the underlying bonds mature, the fund returns capital to investors. Crucially, holding a Target Maturity ETF until its maturity date significantly mitigates interest rate risk, locking in the Yield to Maturity (YTM) at purchase.
• Liquid ETFs (e.g., Nippon India ETF Liquid BeES): Invest in very short-term money market instruments and tri-party repos (TREPS). Traders frequently use Liquid ETFs to park idle trading funds or pledge them as margins on NSE/BSE while earning modest returns.

How to Invest in Fixed Income ETFs?

1. Use a suitable investment or brokerage account that provides access to ETFs.
2. Select from government bonds, corporate bonds, short-term bonds, long-term bonds, investment-grade bonds, or high-yield bonds based on your risk tolerance.
3. Invest an amount that fits your financial goals and overall asset allocation.
4. Search for the ETF using its ticker symbol and place an order through your brokerage platform.
5. Keep an eye on interest rates, fund performance, fees, credit quality, and whether the ETF continues to match your investment objectives.

Benefits of Fixed Income ETFs

There are many benefits that fixed-income ETFs can bring to both new and professional investors.

• Diversification: A single fixed-income ETF may contain several dozen, hundreds, and even thousands of bonds. Thus, the money is invested in different issuers and securities rather than in a single bond.
• Easy Access to the Bond Market: Individual bonds are often difficult to purchase, especially for those who are investing in bonds for the first time. Fixed income ETFs give a chance to access the bond market in an easier manner. ETF units can be purchased via a regular brokerage account like ordinary shares.
• Fixed Income: The majority of fixed-income ETFs earn income from the interest generated by the bonds included in the fund's portfolio. In some cases, the income is distributed to investors. Therefore, fixed income ETFs can become a good source of regular income.
• Liquidity: Since ETFs are traded on stock exchange markets, investors can purchase or sell them whenever the market is open. Thus, they are usually more liquid than some individual bonds since it may be hard to sell them at a proper price.

Risks of Investing in Fixed Income ETFs

There are several risks associated with fixed income ETFs that investors need to be aware of.

• Interest rate risk: Rising interest rates can cause bond prices and ETF values to decline.
• Credit risk: It is the risk of non-payment of interest and principal from the issuing entity, which can usually happen with bonds of lower quality.
• Liquidity and Tracking Error Risk: Premium or discount divergences from iNAV during periods of market stress, or minor tracking differences between the ETF and its benchmark index.
• Inflation risk: If there is a spike in inflation, then fixed interest rates will fall in terms of their buying power.

How to Choose and Invest

• Define Your Horizon & Goal: Match your investment timeline to a Target Maturity ETF if you intend to hold until maturity, or choose Liquid/Short-Term ETFs for flexible parking of funds.
• Evaluate Portfolio Quality: Check the underlying credit mix (sovereign G-Secs/SDLs vs. AAA corporate bonds).
• Review Costs & Liquidity: Compare expense ratios and verify average daily trading volumes on the exchange.
• Execute via Brokerage: Search for the ETF ticker on your trading platform, check the live iNAV against the market price, and place your order.

Conclusion

Fixed income ETFs have revolutionised the way many investors trade in the bond market, as opposed to holding individual bonds that require active management. Their attributes of diversification, ease of access, liquidity, and possibility of earning income make them valuable investment tools. However, investors should note that fixed income ETFs are not risk-free investments.

The most crucial thing is to know what you are investing in. The risks associated with a short-term government bond ETF will be quite different from those of a long-term corporate or junk bond ETF.
