Few weeks ago I read a story about Capitol One trader who made a big derivatives bet on oil that has gone sour. Story goes, the CFTC "quietly gave them a temporary bailout" (don't know how that works) for 1 quarter. Said, "if the price of oil stayed near $20 or went lower (don't know how close it needs to be to $20), Capitol One would have a margin call of ~$1Billion... which could leave the bank insolvent." I had money there because they once held my mortgage. Moved it. You might want to research that if it could affect you. "What's in your wallet?" FWIW...
