According to new data bank branches in the US decreased by 1,700 over the last 12 months; this is the biggest decline on record; closings are concentrated in big cities and surrounding suburbs and is attributed to less foot traffic; other closures occurring in rural areas are due to some regional lenders leaving the area; the decrease in regional bank branches is something that has accelerated more recently compared to big banks beginning to close branches years ago; Capital One, SunTrust and Regions have closed 32%, 22% and 12% of their branches respectively from mid-2012 to mid-2017.
