Citi makes "bank" betting on its own demise.

Citi Reports $4.69 Billion in Fixed Income Trading

...something magic happened in the fixed income trading group for Citi. This is pure gold if you like arcane financial statements packed with fictional earnings. If you dig into the quarterly report, you'll learn than fixed income trading revenues were boosted by a "net $2.5 billion positive CVA on derivative positions, excluding monoclines, mainly due to the widening of Citi's CDS spread.

That takes some sorting out. A CVA is a "credit value adjustment." As you can learn here, it's the credit risk premium of a derivative contract. Once you sort it out, you learn that Citi "made" $2.5 billion on a derivatives position designed to profit when the companies own credit default swaps spreads widen.

Or, in plain English, Citi profited because it made a bet that the cost of insuring itself against a default would go up. The credit default swap market is the place where you can bet on the credit worthiness of a firm, or, essentially, the chance that a firm might default on its bonds. Citi appears to have reported a $2.5 billion trading gain in the fourth quarter precisely because the market thought the company stood a good chance of failing (hence the widening CDS spread).

Now that's some life insurance policy!!
