Credit Spreads and Equity Volatility during Periods of Financial Turmoil
AbstractWe present a joint analysis of the term structure of credit default swap (CDS) spreads and the implied volatility surface for the United States and five European countries from 2007– 2012, a sample period covering both the Global Financial Crisis (GFC) and the European debt crisis. We analyze to which extent effective cross-hedges can be performed between the CDS and equity derivatives markets during these two crises. We find that during a global crisis a breakdown of the relationship between credit risk and equity volatility may occur, jeopardizing any cross-hedging strategy, which happened during the GFC. This stands in sharp contrast to the more localized European debt crisis, during which this fundamental relationship was preserved despite turbulent market conditions for both the CDS and volatility markets.
