Depositors Insurance Fund

Established by the Massachusetts legislature in 1934, the Depositors Insurance Fund (DIF) is a private, industry-sponsored insurance fund that insures all deposit accounts above Federal Deposit Insurance Corporation (FDIC) limits at its member banks.

The unique combined insurance coverage afforded by the FDIC and the DIF ensures deposit balances are fully protected.

Since the DIF was established, no depositor has ever lost a penny in any Massachusetts savings or cooperative bank.
