HSBC lost a lot of money from it's venture into North America. Now they are withdrawing and have sold their upstate New York branches to First Niagara Bank. I have a checking account with HSBC at an upstate NY branch as well as a credit card account and an online savings account. Apparently, all these accounts, including the online only account, will transfer to First Niagara:
"9. I have an Online Savings/Advance Account, and also accounts at a branch which is included in this transaction. Will my Online Savings/Advance Account transfer with my other accounts?
Upon completion of the sale, if you have a branch relationship, all accounts associated with your branch relationship (including Online Savings/Advance) will be automatically transferred."
Snork Maiden has an online only account with HSBC and so apparently her account will stay with HSBC. The full FAQ is here.
