bond to the current price of the bond

FACTORS AFFECTING BOND PRICES Coupon Direct relationship between coupon and Bond price
Interest rates on comparable bonds (Yield) Depends on various factors - Credit quality, Liquidity, Embedded options, Tenure, etc.
Inverse relationship between interest rates and Bond price
Tenor For zero coupon bonds, inverse relationship (assuming a flat or an upward sloping yield
curve)
For coupon bonds, relationship would depend on coupon rate and yield
Embedded Option Value of a callable bond = Value of similar plain vanilla bond - Value of the call option
Value of a putable bond = Value of similar plain vanilla bond + Value of the put option
Value of bond with conversion option = Value of similar plain vanilla bond + Value of the conversion option

WHY DIFFERENT YIELDS?
Yield of a bond depends upon various factors:
Type of issuer
Perceived Credit risk
Term of the issue
Embedded options
Tax aspects
Expected liquidity

BOND PRICE VOLATILITY / INTEREST RATE RISK
Price Volatility on account of changes in interest rates
Refer Excel Illustration

![Page 25: FIXED INCOME SECURITIES - rvoicmai.in](https://reader033.vdocuments.site/reader033/viewer/2022042702/626570f18a53a835d07f0783/html5/thumbnails/25.jpg)
BOND PRICE VOLATILITY - KEY CHARACTERISTICS Inverse relationship between price and yield (interest rates)
For a small change in yield, price increase (on account of reduction in interest rates) and price
decrease (on account of same increase in interest rates) are roughly same
For a large change in yield, price increase (on account of reduction in interest rates) is higher
than the price decrease (on account of same increase in interest rates)
The higher the Maturity, the higher will be the price volatility
The lower the Current yield, the higher will be the price volatility
The lower the Coupon rate, the higher will be the price volatility

MODIFIED DURATION
Modified duration provides an estimate of % change in price for a given change in yield
% change in price = (-Modified Duration * change in yield in %)
Example: If a bond has a Modified Duration of 4.5, then a 1% increase/decrease in yield would result in 4.5% decrease/increase in price
Modified duration provides only a linear estimate of % change in price and ignores the convexity of price curve

MODIFIED DURATION Modified duration (Duration) provides an estimate of % change in price for a given change in yield
Duration is an approximation of risk. P (as estimated using duration) captures the linear changes in prices for changes in yield

PROPERTIES OF DURATION Macaulay Duration of a Zero coupon bond is always same as its maturity
For a coupon paying bond, Macaulay Duration would be lesser than its maturity
The greater the coupon, the lower would be the Duration, and vice-versa
The price estimated by the duration would always be an under-estimate, because of positive convexity of bonds For a small change in interest rate, the price estimated by duration would be closer to the
actual price
If interest rates changes are big, the price estimated by duration would be farther from actual price
The lower the current yield of the bond, the higher would be the duration
Further, as interest rates fall, the duration of the bond would rise
