Large banks continued to dominate market share in terms of deposits, with six banks controlling about 65 percent of the market in Massachusetts, according to recently released FDIC data for the end of the second quarter of this year.
Citizens Bank saw the biggest year-over-year jump, as it grew deposits by $5.3 billion and increased its market share from 8.8 percent at the end of the second quarter of 2016 to nearly 10.5 percent at the end of the second quarter of this year.
Bank of America was right behind, growing its deposits close to $5.1 billion and increasing its market share to almost 21 percent in the state. It still remains way ahead of Citizens and almost every other bank in the state with $73.2 billion in deposits.
California-based First Republic Bank also saw a year-over-year bump, growing deposits from $5.6 billion, or 1.58 percent of market share, to $7.28 billion, or 2.08 percent, of the Massachusetts market.
State Street, the leader in Massachusetts, lost ground year-over-year. Its total deposits in Massachusetts plummeted from $93.4 billion, or 26 percent of the market, to $79.1 billion, or 22 percent of the market. State Street is different from other banks because it is a custodian bank and does not have branches like the others.
Eastern Bank remained at the top of the list of community banks with 2.42 percent market share. For the most part, community banks remained in similar positions as they were in at the end of the second quarter of 2016. One exception was East Boston Savings Bank, which jumped just barely ahead of Century Bank this year.
Total deposits in Massachusetts declined from $356.4 billion at the end of the second quarter of 2016 to $350 billion at the end of the second quarter of this year.
