Just found this from wamu:

Q. I have Certificates of Deposit (CDs) at both WaMu and Chase. Are both of those FDIC-insured?

A. Yes! WaMu CDs are separately insured from JPMorgan Chase Bank, N.A. accounts until March 24, 2009. And insurance for WaMu CDs existing on September 25 may be extended: WaMu CDs maturing after March 24 , 2009, which roll over without any changes ( such as amount, term, or title), are separately insured until their first maturity date after March 24, 2009. WaMu CDs opened on or after September 26, 2008, will be combined with all other JPMorgan Chase Bank, N.A. accounts to determine FDIC insurance.
