The Share Insurance Fund (SIF) is a private fund owned by the member co-operative banks, which insures all deposits at co-operative banks in Massachusetts above Federal Deposit Insurance Corporation (FDIC) limits.
The unique combined insurance coverage afforded by the FDIC and the Share Insurance Fund provides the best deposit insurance available, whether deposit balances are held in passbook, statement or certificate-type accounts, or in any combination of these accounts. At a Massachusetts co-operative bank, your deposits are always fully protected.
Since its inception, the Share Insurance Fund has preserved the enviable claim of member co-operative banks that “no depositor has ever lost a penny in any Massachusetts co-operative bank.”
