More than 600,000 U.S. consumers have moved their money from big banks to community banks or credit unions, thanks to the much-publicized Bank Transfer Day last fall, according to an analysis released by Javelin Strategy & Research. The grassroots campaign to get people to shift out of big banks capitalized on the nationwide Occupy Wall Street movement, and picked up further momentum from a Bank of America plan in September to charge customers a $5 per month debit card fee. It was a meaningful movement of people from big banks into small community banks and credit unions ..." said Jim Van Dyke, founder of Javelin. Historically, people don't switch banks easily, even if they are unhappy, Van Dyke says. Consumers have strong ties to their banks because of direct deposit, automated bill payments and habit -- making change more complex than simply going someplace else. "Individuals are really resistant to moving their money out of banks," Van Dyke says. Overall, about 5.6 million people moved their bank accounts in the last quarter of 2011, Javelin says. Account changes attributed to Bank Transfer Day represented about 11 percent of total moves.
