We study the dynamic impact of idiosyncratic volatility and bond liquidity on corporate bond spreads over time and empirically disentangle both effects. Using an extensive data set, we find that both idiosyncratic volatility and liquidity are critical mainly for the distress portfolios, i.e., low-rated and short-term bonds; for others only volatility matters. The effects of volatility and liquidity shocks on bond spreads were both exacerbated during the recent financial crisis. Liquidity shocks are quickly absorbed into bonds prices; however, volatility shocks are more persistent and have a long-term effect. Our results overall suggest significant differences between how volatility and liquidity dynamically impact bond spreads.

We study secondary market trades of debt issues by foreign firms in the U.S. under SEC Rule 144A, a unique market where the counterparties are qualified institutional buyers (QIBs). We find that even though the secondary yield spreads of foreign 144A debt issues are larger than comparable public debt issues by foreign and domestic firms in the U.S., the incremental impact of common risks – namely, credit, illiquidity, governance, and familiarity risks – on spreads are lower for foreign 144A issues compared to various control samples. Our finding is consistent with the notion that institutional participants, namely QIBs, play a specialized role in mitigating risk exposures in the foreign 144A secondary market.
