Perhaps the interest rates may be similar to what Chase offers
Ouch, I hope not. Regular savings accounts are getting 0.10% - 1.95% depending on the type of account and balance. Compare to Wamu's 4% APY
That's because Chase is not desperate for cash.
In Chicago, WaMu had much better business rates than Chase. I used Chase for some personal accounts because of ATMs, but WaMu for several business accounts.
