WASHINGTON – Citizens Bank’s dominance in Rhode Island in terms of deposits got wider in the past year as its deposits increased by $3.43 billion – or 35.4 percent – while deposits at Bank of America Corp. and Sovereign Bank grew at a much slower clip.

The annual market-share report released yesterday by the Federal Deposit Insurance Corporation (FDIC) showed that Providence-based Citizens held 44.31 percent – or $13.11 billion – of the state’s $29.59 billion in deposits as of June 30. That’s up from the 38.03-percent market share Citizens had in 2007.

Meanwhile, Bank of America recorded $6.72 billion in deposits in the Rhode Island market as of June 30, up from $6.51 billion the year before. But Charlotte, N.C.-based BofA’s market share declined from 25.59 percent to 22.7 percent.

Likewise, Sovereign’s deposits climbed to $2.39 billion as of June 30 from $2.07 billion posted a year earlier. The Philadelphia-based savings and loan’s market share declined slightly from 8.15 percent to 8.09 percent.

The Washington Trust Co., the No. 4 bank and Rhode Island’s largest independent bank, lost some ground as deposits declined to $1.55 billion from $1.60 billion in the previous year. Bank Rhode Island made a slight gain, to $1.04 billion from $1.03 billion.

Further down the FDIC’s market share list, Union Federal Savings Bank jumped from 14th to 10th, as its deposits surged to $244.56 million as of June 30, from $53.59 million the year before.

While the one-office outfit in North Providence still has a tiny market share, the jump from 0.21 percent in 2007 to 0.83 percent now puts it ahead of Newport Federal Savings Bank and Domestic Bank in terms of deposits.

A call to Union Federal Savings Bank seeking comment was not immediately returned.
