Maybe Cos Cob will have to live with nine (or more) banks awhile longer. This article points out that the branch banks are still alive. Yes, on-line banking is rapidly expanding, but old folks still like to look their teller in the face and see if she’s cheating them. And unlike other funds, deposits from these oldsters come incredibly cheap. Pay them nothing, lend out dearly, and the spread is yours to keep. But that doesn’t mean the day of the branch bank isn’t numbered and, eventually, Cos Cob will see the bricks and vaults of Peoples/Chase/BankofGreenwich/Citi/Hudson/Etc. replaced by something more profitable – probably nine new branches of CVS.
