Bond yield: What is it?

A bond yield is the money an investor gets back from buying a bond. In other words, a bond yield stands for the investor’s return on money. The yield on a bond is not the price of the bond. In fact, they are inversely correlated. 

When the bond is released, the return is the same as the dividend rate. There are several ways to find the yield on a bond, such as the coupon yield and the current yield. Among other things, yield to maturity (YTM) is another way to figure out a bond’s yield.

When someone buys a bond and keeps it until it matures, the yield to maturity shows them how much they are likely to earn. Meaning the bond is not traded on the secondary market by the investor. Instead, they wait until the bond matures before selling it. 

As a result, the yield to maturity of a bond accounts for both the value at maturity and all anticipated future cash flows through maturity, including interest due. If you look at the present value of these future cash flows, they match the bond’s current price. This is called the YTM.

Example of bond yields

For example, if an investor invests in a bond with a face value of INR 10,000 and a yearly coupon rate of 8%, the bond will pay 800 INR in interest yearly. If bond interest rates rise above 8%, the investor will have to sell the bond at a lower price.

It is more appealing for investors to get a coupon payment on a bond if interest rates go down. As rates fall even more, the price of the bond will go up. For a new investor, the interest rate no longer means anything in either case. However, the investor can figure out the present yield and get an approximation of the bond’s true yield by dividing the yearly coupon rate by the bond’s price.

The relationship between bond yield and bond price

Contrary to popular belief, there is a relationship between the bond yield and the bond price. An increase in bond price means a decrease in yield and vice-versa. Bonds with low prices and high values are usually preferred for investing. But when you want to sell them, you might wait for their market value to increase. You might want higher bond rates instead if you are considering keeping the bond until it matures so that your total returns stay high.

How to calculate bond yield?

The easiest way to figure out the return on a bond is to divide the coupon payment by the bond’s face value. To put it in a formula:

Bond yield (coupon rate) = Annual coupon rate / Bond face value

For instance, a bond with an INR 2,000 face value would pay INR 400 in interest or coupons every year. This means that the coupon rate is 20%, or INR 400 divided by INR 2,000.

The connection between bond yields and the stock market

  • Yields on bonds and the cost of capital

Companies need a certain rate of return to cover the opportunity cost of borrowing money. This rate is called the cost of capital (COP). It figures out how much people are ready to risk that their money won’t earn as much as they thought it would. 

How much it costs for businesses and buyers to borrow money is largely based on bond rates. Government bond interest rates, which are usually higher than those on government assets, are what drive corporate bond yields.

  • The yields on bonds and foreign funds

More people will want to buy bonds if yields go up. Let’s say that at a certain point in time, the yields on Indian bonds are higher than those on the international bond market. Investors from around the world will find Indian debt more appealing than global debt.

Additionally, if the debt market seems more appealing than the stock market, foreign institutional investors (FIIs) will move their money toward the stock market. 

  • Opportunity cost

A higher opportunity cost may make buying in stocks less appealing if bond yields rise high enough to beat the profits from stocks. 

The chance cost of investing in them is another way to look at the link between them. You are missing out on the chance to get better results on another investment when one becomes more appealing. This is called “opportunity cost.”
