The expectechange in yielbaseon a 99% confinintervfor the bonana 1.50 bps yielvolatility over 21 trang ys equals 16 bps = (1.50 bps × 2.33 stanrviations × 211/2). We cquantify the bons market value change multiplying the famili(–Mour × △Yiel expression bonprito get $1,234,105 = ($75 million × 1.040175 ⨯ (–9.887 × .0016)). 老师，我按照基础班讲义“P335-336”的例题做的，按照讲义的做法，当给出的是0.8bps，是利率变动波动率即σ(△y/y)，所以需要转换成利率波动率，即σ(△y)=y×σ(△y/y)=4%×0.8%，再进行计算。若按照基础班讲义做，此题已知的是bps，应该也是利率变动波动率吧？则σ(△y)=2.85%×1.5%=0.0428%VaR=2.33×0.0428%×21^½=0.4569%VaR=(-9.887)×0.4569%×(75,000,000×104.0175/100) = -3,524,141.74答案没有该，是我哪一块理解错了，还是答案有问题呢？
