This paper documents a positive cross-sectional relation between returns and lagged idiosyncratic volatility (IVOL) in the corporate bond market. The relation is stronger following periods of low funding liquidity due to a funding liquidity driven decrease in returns and its subsequent reversal. Three exogenous shocks – (i) the Volcker Rule which restricted the participation of dealers in the corporate bond market in 2014, (ii) the Global Financial Crisis of 2008, and (iii) the COVID-19 crisis of 2020, are used to establish causality between funding liquidity and the positive IVOL-return relation.
