Investing in Debt Instruments: Meaning, Types, Benefits, Risks and More

When it comes to investing, the first things that often come to investors’ minds are stocks, mutual funds, gold, or real estate. However, debt investments are another option that is overlooked despite their potential to play an important role in building a balanced investment portfolio.

Debt investments refer to the process whereby the investor lends their money to the government, a corporation, a bank, or another financial institution for a particular period of time. In return, the issuer promises to pay interest along with the principal amount at the maturity of the debt instrument.

These investments can be helpful for investors seeking stable returns and lower risk than equity investments. They can also be helpful for investors who want regular income or want to protect a part of their portfolio from the volatility of the stock market. In this article, we will explain what debt instruments are, their types, benefits, risks, and more.

What are Debt Instruments?

A debt instrument is simply an agreement between two parties wherein one party borrows money from the other.

Imagine a company wants to borrow ₹10 crore for expansion purposes. However, instead of borrowing the entire amount from a financial institution like a bank, the company issues bonds. Investors invest their money in the bonds, and the company will pay interest in return as per the terms of the bonds. At the maturity date, the company returns the principal amount.

The same concept applies when the government borrows money. The government borrows money by issuing securities and paying interest while returning the principal at maturity as per the terms of the security.

Thus, the idea is very simple:

• You lend money.
• You earn interest.
• Your principal is returned at maturity.

Types of Debt Instruments in India

There are many different debt instruments available in India. While some are designed specifically for retail investors, others are more popular among institutional investors.

Government Securities

Government securities, or G-Secs, refer to debt securities issued by the Government of India to raise funds.

Government securities can be categorised based on the duration of their maturity. Short-term government securities comprise treasury bills, while long-term government borrowing includes dated government securities.

One of the biggest features of government securities is their relatively lower credit risk, as they are backed by the government. On the other hand, government securities are not immune to changes in the interest rate environment. In the event of an increase in interest rates, the market price of existing fixed-rate bonds usually drops; conversely, bond prices usually increase when interest rates drop.

For example, if you purchase a government bond and hold it until maturity, fluctuations in the market price of this instrument will not affect you. If, however, you want to sell your investment before maturity, then the current market price is essential.

Treasury Bills

Treasury Bills, also known as T-Bills, are instruments that are issued by governments.

These instruments have short maturities, and they are issued at a discount to their face value. The investor is paid the face value at maturity, and the difference between the face value and the issue price is the income earned by the investor.

For example, if the face value of a Treasury Bill is ₹100 and you buy it for ₹98, you get ₹100 at maturity, and the ₹2 difference is your income. Treasury Bills are considered relatively safe short-term investments.

Corporate Bonds

Corporate bonds are instruments issued by corporations to raise money for various purposes. The money raised through issuing corporate bonds may be used to expand operations, meet working capital requirements, pay off some debts, or for other business purposes.

Corporate bonds may generate higher interest rates compared to government securities due to the extra risk associated with the bonds. This extra risk results in an extra reward in the form of higher yields, at least in many cases. However, one should not always assume that a higher interest rate is a better investment.

If a company provides a very high interest rate compared to safer alternatives, investors should always consider the issuer’s credit quality, financial health, security offered, maturity, and liquidity before investing.

Non-Convertible Debentures

Non-convertible debentures, or simply NCDs, are yet another type of corporate debt that cannot be converted into equity shares of the issuing company. NCDs might carry fixed or structured interest rates and have different tenures.

Before making any investment decision, investors should study the offer document. One should always consider the credit rating of the issuer, interest payment plan, tenure, secured/unsecured status, and premature repayment clause of the debenture.

Debt Mutual Funds

Investors who do not wish to invest in individual bonds can invest in debt mutual funds.

Debt mutual funds invest in various kinds of debt instruments, such as government securities, corporate bonds, and money market instruments, depending on the scheme’s investment objectives.

However, debt mutual funds are not the same as a fixed deposit, and their value, represented by the mutual fund’s NAV, varies on account of fluctuations in the securities held in the mutual fund portfolio. This becomes more significant when there is a change in interest rates.

Benefits of Investing in Debt Instruments

• Steady and Predictable Income: A major benefit of debt instruments is that they offer regular interest payments. The frequency of these payments varies according to the product and may be on a monthly, quarterly, half-yearly, or annual basis. Such a feature can be helpful for investors who are looking for a steady income stream.
• Less Volatility than Equities: Debt securities usually show less price volatility than shares, especially when compared with individual equities; this feature makes them suitable for investors who are not comfortable with large fluctuations in the value of their investments.
• Helps Protect Capital: High-quality debt instruments, especially government securities, offer a fairly stable method of preserving capital. If an investor holds the bond until maturity and the issuer fulfils its obligations, the principal is usually returned in accordance with the terms of the investment.
• Helpful for Financial Goals: Debt investments can be matched with particular financial goals. For example, an investor who is saving for a goal that is three years away might choose an investment with the same maturity rather than assuming excessive risk in the equity markets. Matching the maturity of an investment with the time when you need the money can make financial planning easier.
• Portfolio Diversification: Debt can add balance to a portfolio that includes equities or other higher-risk assets. If one section of the portfolio is undergoing volatility, the relatively stable debt investments can serve to reduce the overall effect. It is especially beneficial for investors who wish to combine growth with stability.
• Wide Variety of Options: There are several debt options, including government securities, Treasury Bills, corporate bonds, NCDs, bank deposits, and debt mutual funds available to investors. Since the various products have different maturities and risk levels, investors can select the ones that match their financial goals.

Risks of Investing in Debt Instruments

• Credit or Default Risk: Credit risk, also called default risk, refers to the possibility that an issuer may default on interest or principal payments. This risk is primarily associated with corporate bonds and debentures. A financially weak company might offer a high interest rate to attract investors, but this higher return is accompanied by a greater chance of default.
• Interest-Rate Risk: Interest rates and bond prices tend to move in opposite directions. If market interest rates rise after you purchase a fixed-rate bond, the market value of your existing bond may fall. This matters especially if you want to sell the bond before maturity. Longer-term bonds can be more sensitive to interest-rate changes than shorter-term instruments.
• Liquidity Risk: Liquidity risk arises when you cannot easily sell an investment when you need your money. Some bonds may have limited trading activity. Even if the issuer is financially sound, finding a buyer at a reasonable price may be difficult. Therefore, investors should consider liquidity before investing in a long-term debt instrument.
• Inflation Risk: Inflation can reduce the real value of your returns. For example, if a debt investment earns 7% but inflation is 6%, the increase in your purchasing power is much smaller than the headline return suggests. For long-term investors, it is important to consider whether the expected return is sufficient to stay ahead of inflation.
• Reinvestment Risk: Reinvestment risk occurs when you receive interest or your investment matures, but the available investments at that time offer lower interest rates. For example, if you previously earned 8% and interest rates later fall to 6%, you may have to reinvest your money at the lower rate. This can reduce your expected income over time.
• Concentration Risk: Investing a large portion of your money in a single company or type of debt can increase risk. If that issuer experiences financial difficulties, a significant part of your portfolio could be affected. Spreading investments across different issuers, maturities, and types of debt can help manage this risk.

Taxation of Debt Instruments in India

Investors should consider taxation rules, as taxation is an important factor when investing in debt instruments. Since tax rules can change, investors should check the latest provisions before investing, especially when investing larger amounts.

Tax on Interest Income

Interest income generated from instruments such as bonds and fixed deposits is taxable under the applicable income-tax rules. The actual tax payable depends on the investor's income and tax regime.

Tax on Capital Gains

If you sell a debt security for more or less than its purchase price, you may make a capital gain or incur a capital loss. The tax treatment depends on the type of debt instrument and the prevailing tax rules.

Focus on Post-Tax Returns

Investors should compare post-tax returns, rather than looking only at the advertised interest rate. A higher interest rate does not always mean a better investment after taxes.
