同学你好
如果利率的波动变大,投资者会买入更多convexity,因为有涨多跌少的好处,从而使得长端收益率下降,曲线的曲率变高,因此barbell的表现会更好。
Convexity is therefore valuable when interest rate volatility is expected to rise. This dynamic tends to cause investors to bid up prices on more convex, longer-maturity bonds, which drives changes in yield curve shape. As a result, the long end of the curve may decline or even invert (or invert further), increasing the curvature of the yield curve.
