同学,你好!
所有关键利率合在一起相当于是一条收益率曲线,有效久期就是衡量整条收益率曲线的,包含了所有关键利率。
duration分两种:risk measures based on changes in the bond´s yield-to-maturity (yield duration) and on benchmark yield curve changes (curve duration).
key rate durations (also known as partial durations), which reflect the sensitivity of the bond´s price to changes in specific maturities on the benchmark yield curve. 所以KRD是衡量的Δcurve的变动。
我们讲的MD,Mac.D都是衡量ΔYTM的变动, 也就是yield duration,只有ED是衡量Δcurve的变动,你看讲义上在duration这页有讲,所以KRD加总等于的是ED。
望采纳,祝通过!
