Abstract

Duration is widely used by fixed income managers to proxy the interest rate risk of their assets and liabilities. However, it is well known that the convexity of the price-yield relationship introduces approximation errors that grow with changes in yield. In this article we suggest a new approach, 'discrete duration', which significantly improves upon the accuracy of traditional duration methods and achieves a level of accuracy close to the more complex 'duration-plus-convexity' measure. In particular, discrete duration performs particularly well for long dated and low coupon rate bonds where the estimation error is impressively close to zero.
