Why Are Low Coupon Bonds More Volatile?

While no one can anticipate where interest rates will go in the future, looking at the “duration” of each bond, bond fund, or bond ETF you buy can give you a good idea of how sensitive your fixed income holdings are to interest rate changes. Duration is used by investment experts because it combines various bond features (such as maturity date, coupon payments, and so on) into a single statistic that shows how sensitive a bond’s price is to interest rate fluctuations. A bond or bond fund with a 5-year average term, for example, would likely lose about 5% of its value if interest rates rose 1%.

Duration is measured in years, although it is not the same as the maturity date of a bond. The bond’s maturity date, as well as the bond’s coupon rate, are both important factors in determining length. The remaining time until the bond’s maturity date is equal to its duration in the event of a zero-coupon bond. However, when a coupon is added to a bond, the duration number is always smaller than the maturity date. The duration number decreases as the coupon size increases.

Bonds with extended maturities and low coupon rates typically have the longest durations. These bonds are more volatile in a changing rate environment because they are more susceptible to changes in market interest rates. Bonds having shorter maturity dates or larger coupons, on the other hand, will have shorter durations. Bonds with shorter maturities are less volatile in a changing rate environment because they are less sensitive to rate changes.

A bond with a 5% annual coupon that matures in 10 years (green bar) has a longer term and will decline in price more as interest rates rise than a bond with a 5% annual coupon that matures in 6 months (blue bar) (blue bar). Why is this the case? Because short-term bonds restore principal to investors more quickly than long-term bonds. As a result, they pose a lower long-term risk because the principle is returned earlier and can be reinvested.

Are bonds with lower coupon rates more volatile?

When interest rates are predicted to fall, bond prices are expected to climb across the board, thus bond investors should focus on the most volatile bonds, with prices rising faster than others. The bond’s price is more variable when the coupon rate is low. Bond investors should pick lower-interest-rate bonds over higher-interest-rate bonds in a dropping interest-rate environment because higher-interest-rate bonds are less volatile and rise in price less.

Why do low-coupon bonds have a longer term?

Because proportionately less payment is paid before final maturity, a bond with a smaller coupon has a longer duration. Because more payment is received before final maturity, a bond with a higher coupon has a shorter duration.

Do high-yield bonds sell for more or less than low-yield bonds?

Are high-coupon bonds more expensive or less expensive than low-coupon bonds? Higher. A one-year 10% bond is valued $110 / 1.1 = $100, while a one-year 8% bond is worth $108 / 1.1 = $98.18 if r = 10%.

Are bonds with higher coupon rates more volatile?

Bonds have two characteristics that influence price volatility in reaction to changes in market interest rates. A lower coupon rate bond will be more volatile than one with a higher coupon rate. In addition, longer-term bonds are more volatile than shorter-term bonds. The amount a bond’s price swings in reaction to a certain change in interest rates is referred to as volatility in this scenario.

Are bond prices unpredictable?

Changes in interest rates have an impact on the value of most bonds and bond strategy. Longer-duration bonds and bond strategies are more susceptible and volatile than shorter-duration bonds; bond prices decline as interest rates rise, and low interest rate environments exacerbate this risk.

What do volatile bonds entail?

Volatility is a term used to describe the level of risk or uncertainty associated with the size of variations in a security’s value. A security’s value can potentially be spread out over a greater range of values if its volatility is higher. This means that the security’s price can swing drastically in either way in a short period of time. Lower volatility indicates that the value of an asset does not vary substantially and is more stable.

When bond prices fall, why do bond rates rise?

This is due to the fact that the bond market is mostly driven by the supply and demand for investment capital. When investors are unwilling to spend money on bonds, their price falls, causing interest rates to climb.
