We examine whether CDS prices around the Credit Crisis can be explained with Merton’s model. First we invert the model with market prices to reveal skewed volatility smiles over the whole 2005–2012 period. Then we calibrate the model to pre-Crisis data in two novel ways that allow for skewness, one based on equity-index options (MEIV) and the other on the sensitivity of CDS prices to equity volatility (MSKEW). In out-of-sample forecasts both calibrations match the in-Crisis peak of prices, but the second is better at capturing the systematic component of prices thereafter. Average CDS prices remain at twice their pre-Crisis level long after that event; the MSKEW calibration demonstrates that this is due to extra idiosyncratic risks, which are important for some firms but have negligible impact on others.

Using a novel dataset, we study intraday trades of overnight general collateral repurchase agreements (repos) on Italian government bonds. We focus both on repos cleared by central counterparties (CCPs) and traded bilaterally. Intraday bond supply, liquidity and duration significantly affect the spread of repo rates over the European Central Bank (ECB) deposit rate, but after the ECB quantitative easing interventions this impact is much reduced. During the European sovereign debt crisis, the increase in margins further deteriorates repo costs, creating a negative procyclical effect. Once we control for the impact of margin costs, CCP-based repos do not appear to be significantly cheaper than bilateral repos. We also show that bonds with lower liquidity and specialness, greater supply and longer duration are more likely to be selected as collateral. However, during the crisis, CCP-repo borrowers choose collateral bonds with higher liquidity and lower duration to reduce margin and repo trading costs.

We find that the magnitude of unique credit default swap (CDS) market information (constructed to be orthogonal to contemporaneous and lagged stock returns) declined after recent reforms that increased the level of post-trade regulatory and market transparency for CDSs. Around the same reforms, the ability of this CDS-unique information to predict future stock returns decreased. These results suggest the CDS market has become less of a “hidden” trading venue for informed investors since central clearing and trade reporting started.
