NO.PZ2016031001000129 问题如下 Whiof the following statements relating to yielvolatility is most accurate? If the term structure of yielvolatility is wnwarsloping, then: A.short-term rates are higher thlong-term rates. B.long-term yiel are more stable thshort-term yiel. C.short-term bon will always experiengreater prifluctuation thlong-term bon. B is correct.If the term structure of yielvolatility is wnwarsloping, then short-term bonyiel-to-maturity have greater volatility thfor long-term bon. Therefore, long-term yiel are more stable thshort-term yiel. Higher volatility in short-term rates es not necessarily meththe level of short-term rates is higher thlong-term rates. With a wnwarsloping term structure of yielvolatility, short-term bon will not always experiengreater prifluctuation thlong-term bon. The estimatepercentage change in a bonpripen on the mofieration anconvexity well on the yielto maturity change. 考点term structure of yielvolatility解析B比较短期收益率和长期收益率。根据题干的描述，呈现一种向下倾斜的yielvolatility，也就是说短期利率的波动性大于长期利率的波动性。因此长期利率相比更加稳定。故B正确。 老师好，这个图啥样啊 ，是横轴t, y轴volatility吗？我本来以为是x为t，y为yiel

请问利率upwar动的影响和wnwarshort term 和 long term一样吗?

    想问下A，是不是A改成volatility are higher 就对了？
