The impact of term spread volatility on economic activity
研究了美国国债收益率曲线斜率波动（期限利差波动）对经济活动的负面影响，发现其冲击会导致工业产出持续下降，且比期限利差本身更具预测力，对货币政策制定有参考价值。
• Term spread volatility (SLOPERV) has a significant recessionary effect on economic activity. • The SLOPERV has a more pronounced macroeconomic effect compared with that of the term spread. • The recessionary effect of SLOPERV remains robust when controlling for VIX and EPU. • Monetary authorities should target not only the slope of the yield curve, but also the SLOPERV. We examine the impact of the volatility of the US Treasury yield curve slope (term spread volatility) on US economic activity within a VAR framework. Our findings show that a positive shock to term spread volatility leads to a persistent decline in US industrial production. Moreover, our econometric results are the first to demonstrate that term spread volatility absorbs the macroeconomic predictive information contained in the level of the term spread. Finally, the negative effect of term spread volatility remains robust in alternative VAR models, as well when including popular uncertainty proxies such as the VIX and the EPU indexes.
