Credit Suisse has $34 billion in CMBS, RMBS and CDO exposures. Or, hang on a minute, cut that by $2.85 billion: apparently there were some "mismarkings" going on.
There seems to be a lot of people who are very shocked by this, but it’s worth bearing in mind that all these securities are very illiquid, and that in a volatile market with wide bid-ask spreads, reasonable individuals probably can differ by more than 8.5% on the valuation of asset-backed bonds.
