Which bond pricing characteristic indicates a bond's price change as related to its coupon rate?

The bond pricing characteristic that indicates a bond's price change in relation to its coupon rate is that lower coupon bonds are more volatile. This volatility arises because the price of a bond is inversely related to interest rate changes, and this relationship is more pronounced in bonds with lower coupon rates.

When interest rates rise, newly issued bonds often offer higher coupon rates, making existing lower coupon bonds less attractive. This can lead to a more significant decline in the price of lower coupon bonds compared to higher coupon bonds. As a result, lower coupon bonds are more sensitive to interest rate fluctuations, resulting in greater price volatility.

In contrast, higher coupon bonds typically provide more cash flow to bondholders through their higher interest payments, which helps to cushion their price against changes in market interest rates. Therefore, these bonds tend to exhibit lower volatility in their pricing in response to interest rate movements.

The concept of price volatility is essential for investors, as it impacts their potential gains or losses based on interest rate changes. Understanding the relationship between coupon rates and bond price volatility is crucial for effective investment strategy and risk management in fixed-income securities.
