The surge in implied volatility in the financials is impressive today. In Citi, which is trading down $4.95 to $28.49, implied vols in the options are up more than 100 percent and moving into the triple digits (109). BofA (BAC) impled volatility is up 75 percent to 150, State Street (STT) implied vols jumped 75 percent to 70, AIG gained 67 percent to 67, Goldman vols rallied 65 percent to 65, and Morgan Stanley (MS) saw a 63 percent increase to 86. Wells Fargo (WFC), HSBC (HBX), and American Express (AXP) are seeing much higher levels of implied volatility as well. The sector is selling off on the S&P downgrade, which has also resulted in a jump in the cost of insuring US bank debt (credit default swaps). In BofA, for example, the day’s increase was 51 percent to 310 basis points, according to Dow Jones.
