In the following video, Motley Fool financial analysts David Hanson and Matt Koppenheffer look at JPMorgan's (JPM -0.07%) cutting of 4,000 jobs from its retail branches as part of a larger trend. While the move in and of itself isn't all that significant, it represents a shift that many banks are pursuing -- a move to reduce the number of branches and shift into more electronic banking. While this may reduce the number of depositors, larger banks such as JPMorgan, Bank of America (BAC -0.00%), and Wells Fargo (WFC -0.26%) may be shifting strategically away from depositor quantity, and toward quality, with moves to build stronger relationships with their wealthier account holders.
