What it is
Duration risk specifically measures how much a bond's price is expected to change for a given change in interest rates. Bonds with longer maturities or lower coupon payments generally have higher durations, making their prices more volatile when interest rates move. For example, if interest rates rise, a bond with a higher duration will typically experience a larger price decrease than a bond with a shorter duration, assuming all other factors are equal.
Investors in bond markets face duration risk when interest rates are expected to rise. A portfolio heavily weighted with long-duration bonds can see significant capital losses if rates increase unexpectedly. Conversely, falling interest rates benefit long-duration bonds more. Understanding duration helps investors manage the interest rate exposure of their bond holdings, especially in environments where central banks are actively adjusting policy rates, such as during a rate-hike cycle.
Why it matters
Understanding duration risk is crucial for bond investors as it explains how sensitive your bond portfolio is to interest rate changes, directly affecting its value.
