What is Macaulay duration?

Macaulay Duration indicates the potential impact of interest rate changes on the performance of a debt fund. The Macaulay Duration definition states that it is a measure of the time period it will take for the principal of a bond to be repaid from the internal cash flows generated by the bond. Named after Frederick Macaulay, it represents the bond's price sensitivity to changes in interest rates, with higher durations indicating greater price volatility in response to interest rate fluctuations.

Benefits of using Macaulay duration

Here are 3 benefits of using Macaulay Duration:

Interest rate sensitivity: It provides investors and fund managers with insights into a bond's sensitivity to changes in interest rates.

Portfolio optimisation: Macaulay Duration serves as a critical tool for optimising bond portfolios to achieve specific investment objectives and risk tolerance levels.

Fixed-income investment strategies: It plays a central role in designing fixed-income investment strategies, including bond laddering, duration matching and so on.

Factors affecting Macaulay duration

Several factors influence the Macaulay Duration, including:

Time to maturity: Bonds with longer time to maturity typically have a higher Macaulay Duration due to the longer duration of their cash flows and greater sensitivity to changes in interest rates.

Coupon rate: Bonds with lower coupon rates tend to have a higher Macaulay Duration, meaning their cash flows are weighted more heavily toward the maturity date, making them more sensitive to interest rate movements.

Yield to maturity (YTM): Lower yields to maturity result in higher Macaulay Durations, as the present value of future cash flows increases. This leads to greater price sensitivity to changes in interest rates.

Callable and puttable bonds: Callable bonds and puttable bonds may exhibit different Macaulay Durations compared to non-callable bonds. This reflects the impact of embedded options on bond cash flows and price volatility.
