Until it closed its doors in December, the Ohio Savings Bank branch on North Moreland Boulevard was a neighborhood anchor in Cleveland, midway between the mansions of Shaker Heights and the ramshackle bungalows of the city’s east side. Now it sits boarded up, a victim not only of Cleveland’s economic troubles but also of a broader trend of bank branch closings that is falling more heavily on low- and moderate-income neighborhoods across the country.

In 2010, for the first time in 15 years, more bank branches closed than opened across the United States. An analysis of government data shows, however, that even as banks shut branches in poorer areas, they continued to expand in wealthier ones, despite decades of government regulations requiring financial institutions to meet the credit needs of poor and middle-class neighborhoods.

The number of bank branches fell to 98,517 in 2010, from 99,550 the previous year, a loss of nearly 1,000 locations, according to data compiled by the Federal Deposit Insurance Corporation.

Banks are expected to keep closing branches in the coming years, partly because of new technology and automation and partly because of the mortgage bust and the financial crisis of 2008. New regulations will also cut deeply into revenue, including restrictions on fees for overdraft protection — a major moneymaker on accounts aimed at lower-income customers. Yet the local branch remains a crucial part of the nation’s financial infrastructure, banking analysts say, even as more customers manage their accounts via the Internet and mobile phones.

“In a competitive environment, banks are cutting costs and closing branches, but there are social costs to that decision,” said Mark T. Williams, a banking expert at Boston University and a former bank examiner for the Federal Reserve. “When a branch gets pulled out of a low- or moderate-income neighborhood, it’s not as if those needs go away.”
