The âBank Transfer Dayâ campaign called for anybody willing to switch from their retail bank to a credit union on November 5, and it earned a lot of interest. The early Bank Transfer Day numbers show success and obviously worked, as numerous people evidently changed. Between Sept. 29 and Nov. 5, as stated by the New York Times, the Credit Union National Association reported that 650,000 people had joined credit unions in the CUNA and had added $4.5 billion in assets. Credit unions all across the nation were reporting huge increases in membership. In all of 2010, according to CNN, credit unions added 600,000 new members.
