Bonds are a simple and effective way for governments and companies to borrow money. Instead of borrowing from a bank, these entities can sell bonds to a large group of investors to raise the funds they need for operations or growth. Bonds are straightforward instruments that have a fixed coupon rate (or interest rate), a fixed maturity, and a fixed principal.
Understanding Bonds: A Basic Example
Let's say ABC Company issues a bond. The principal amount is ₹1000, the maturity period is seven years, and the interest rate is 8% per annum. As an investor, you would pay ₹1000 for one bond and receive 8% interest annually for the next seven years. After seven years, you get your ₹1000 back. It sounds simple, right?
But what if you don’t want to keep the bond for the entire seven years and decide to sell it earlier? Here’s where things get a bit more complicated.
The Bond Market: Buying and Selling Before Maturity
The bond market works similarly to the stock market, where bonds are bought and sold before they expire. The price of a bond can fluctuate, and these price changes are driven by two major factors:
- Changes in interest rates
- Changes in credit quality
Managing interest rate risk, also known as market risk, is crucial in bond investing. Interest rate risk refers to how bond prices fluctuate based on changes in interest rates.
How Interest Rates Impact Bond Prices
Let’s take an example: Suppose you bought a 10-year bond with a face value of ₹1000 at an 8% interest rate. After two years, you want to sell your bond. But by that time, new bonds with the same maturity of eight years are offering a 10% interest rate.
Now, why would anyone buy your bond with an 8% interest rate when they can buy a new bond offering 10%? To sell your bond, you would need to offer it at a discount. In fact, the price at which a buyer would purchase your bond would be one where your bond yields 10%. The price would drop to around ₹885. This means you would sell your ₹1000 bond for ₹885, resulting in a loss of ₹115 per bond.
Conversely, if interest rates had fallen from 8% to 6%, you could sell your bond at a premium, for about ₹1130, making a profit of ₹130. Thus, bond prices have an inverse relationship with interest rates: When interest rates go up, bond prices go down, and when interest rates go down, bond prices go up.
Real-World Impact of Interest Rate Changes
In bond investing, changes in interest rates are not just theoretical. Significant shifts in interest rates can happen over a short period, impacting bond prices. For instance, if the interest rate of an Indian 10-year bond moves from 7.08% to 5.26%, the bond price would increase significantly. On the flip side, when interest rates rise, bond prices drop accordingly.
However, it’s important to note that bond prices don’t only change when the Reserve Bank of India (RBI) adjusts interest rates. Bond prices fluctuate daily, driven by market expectations of interest rate changes, which are influenced by several factors.
Factors That Influence Interest Rates
Inflation: When inflation rises, the value of currency decreases, and investors demand higher interest rates to compensate for the loss in purchasing power. As inflation increases, interest rates tend to rise, and when inflation declines, interest rates typically fall.
Economic Growth: When the economy slows, central banks like the RBI may reduce interest rates to make loans cheaper and stimulate economic activity. Conversely, in a growing economy, interest rates may rise to control inflation.
Global Liquidity: If global liquidity (the availability of money) is high, it can influence interest rates in a country. More liquidity often means more money flowing into investments, which can put downward pressure on interest rates.
Credit Quality and Bond Prices
Another factor that affects bond prices is credit quality. Continuing with our earlier example, if after two years the interest rate falls to 6%, but the issuing company’s credit quality deteriorates, you might not be able to sell the bond at a premium. In fact, you may have to sell it at a discount.
Can Bonds Give Negative Returns?
Yes, they can. Bond investments are often considered stable, but they can also give negative returns in volatile environments. For example, on February 7, 2017, many debt funds in India lost significant value in a matter of hours after the RBI decided not to cut interest rates. Some funds lost up to 2.6%, which was the return investors expected to make over three months.
Even though bond funds may recover these losses over the long term, investors seeking stable and predictable returns were disappointed. This volatility shows how vital it is to choose the right type of bond or debt fund based on your risk tolerance and investment patience.
Conclusion
Understanding how the bond market works is crucial for managing your investments. Interest rates and bond prices move in opposite directions, and factors such as inflation, economic growth, and credit quality all play a role in determining bond prices. In the second part of this series, we will discuss how you can manage these risks and optimize your bond portfolio for better returns. Stay tuned!
