Branchless banks have started to show their staying power when it comes to deposits in recent quarters even as they lower yields on accounts; Ally Financial, Goldman Sachs, Sallie Mae, American Express and Discover have all increased their deposits in recent months along with lowering rates by 5 percent or more; There’s been skepticism around whether or not it’s a viable market,” Ally Chief Financial Officer Jennifer LaClair said in an interview to American Banker. “We think we’ve answered this question loud and clear.”; there was a fear that the banks would begin losing deposits to challengers or other banks that were able to keep rates high, but that has not proved to be the case so far; the banks have been helped by some of the largest banks keep rates near zero which has made keeping deposits at these branchless banks a lot more appealing.
