Duration

The duration of a bond is a measure of time (in years) expressing either:

  • the weighted average maturity of all discounted bond cash flows (Macaulay duration)
  • or, the bond price sensitivity to yield movements (modified duration) For a bond with a fixed coupon, modified and Macaulay durations are close and linked by the following relationship:
    Modified duration = Macaulay duration/(1+yield) Duration is widely used to measure risks of fixed income portfolios, either the risk of variation in credit spread or in risk-free rates.
