What is Bond Yield?
Bond returns explained - relationship between price, yield, and interest rates
What is Bond Yield?
Bond Yield is the return an investor earns on a bond, expressed as an annual percentage. It represents the effective interest rate you receive on your bond investment, considering both the coupon payments and any capital gain or loss if bought at a price different from face value.
For example, if you buy a ₹1,000 face value bond with 8% coupon for ₹950, your yield will be higher than 8% because you're getting the same ₹80 annual interest on a lower investment of ₹950. Bond yields move inversely to bond prices - when prices fall, yields rise, and vice versa.
💡 Key Point: Bond yield is the most important metric for bond investors as it determines the actual return on investment and helps compare different bonds.
Types of Bond Yields
Current Yield
- • Annual coupon ÷ Current market price
- • Simple calculation method
- • Doesn't consider capital gains/losses
- • Useful for income-focused investors
- • Example: ₹80 coupon ÷ ₹950 price = 8.42%
Yield to Maturity (YTM)
- • Total return if held till maturity
- • Considers all cash flows
- • Includes capital gains/losses
- • Most comprehensive yield measure
- • Assumes reinvestment at same rate
Yield to Call (YTC)
- • Return if bond is called early
- • Relevant for callable bonds
- • Usually lower than YTM
- • Important for premium bonds
- • Helps assess call risk
Running Yield
- • Similar to current yield
- • Annual income ÷ market price
- • Focuses on cash flow generation
- • Ignores maturity considerations
- • Used for perpetual bonds
Price-Yield Relationship
Inverse Relationship Explained
When Interest Rates Rise:
- • New bonds offer higher coupons
- • Existing bonds become less attractive
- • Bond prices fall to match market rates
- • Yields on existing bonds increase
- • Capital loss for bondholders
When Interest Rates Fall:
- • New bonds offer lower coupons
- • Existing bonds become more valuable
- • Bond prices rise above face value
- • Yields on existing bonds decrease
- • Capital gain for bondholders
Example Bond
Face Value: ₹1,000
Coupon: 8%
Annual Interest: ₹80
Scenario 1
Market Price: ₹950
Current Yield: 8.42%
Trading at discount
Scenario 2
Market Price: ₹1,050
Current Yield: 7.62%
Trading at premium

Frequently Asked Questions
Why do bond prices fall when interest rates rise?
When new bonds offer higher interest rates, existing bonds with lower coupons become less attractive. Their prices must fall to offer competitive yields to new investors.
Which yield measure should I focus on?
Yield to Maturity (YTM) is the most comprehensive measure as it considers all cash flows and capital gains/losses. Use current yield for income comparison only.
How does credit rating affect bond yields?
Lower-rated bonds must offer higher yields to compensate for increased default risk. AAA bonds have lowest yields while junk bonds offer highest yields.
Can I predict bond price movements using yields?
Bond duration helps estimate price sensitivity to yield changes. A bond with 5-year duration will fall ~5% in price for every 1% rise in yields.
What is a normal yield curve shape?
Normal yield curve slopes upward - longer maturity bonds offer higher yields. Inverted curves (short rates > long rates) often signal recession.
Should I buy bonds when yields are high or low?
High yields mean better income but potential capital losses if rates fall further. Low yields offer capital appreciation potential but lower income.
