spread risk不懂。 为什么在用Derivative overlay时Spread risk是一个concern? Movements in the corporate–Treasury yield spread introduce risk to the hedging strategy.Usually, yields on high-quality corporate bonds are less volatile than on more-liquid Treasuries. Government bonds are used in a wide variety of hedging as well as speculative trading strategies by institutional investors. Also, inflows of international funds typically are placed in government bonds, at least until they are allocated to other asset classes. Those factors lead to greater volatility in Treasury yields than comparable-maturity corporate bonds. ” Excerpt From 2022 CFA Program Level III Volume 2 Derivatives, Currency Management, and Fixed Income CFA Institute This material may be protected by copyright.

同学,早上好。
1. 信用利差是在经济变好的时候缩窄而在经济变差的时候扩大,基准利率会在经济变好的时候上升(可以理解为经济更好有更高的收益率)而在经济变差的时候下降。那么信用债券会在两者的变动下导致整体的利率波动反而比较小(因为两者的变动会抵消一部分),而国债仅是基准利率,则波动较大;
2. 那么基于上述说明,如果做衍生品对冲则会收到利率波动率的影响,利差部分的变化与整体利率变化就需要考虑在内。
