Lessons from New England bank failures

Abstract

The failure of the Rhode Island Share and Deposit Indemnity Corporation (RISDIC), a private insurance fund, and the closure of its 45 remaining member institutions froze the accounts of 300, 000 individuals and 10 percent of all deposits in the state. While the closure of two institutions triggered RISDICs demise, flaws in both design and management had set the stage for failure and are the focus of this article. The authors group RISDICs problems into three categories: risk concentrations, control of the insurance fund by those it insured, and RISDICs inadequate regulatory oversight of members. ; Concentrations of risks abounded. Both the fund and the geographic area it covered were small, and member institutions lent heavily in real estate. The funds failure to sufficiently reserve against this exposure was particularly problematic: RISDIC could not have covered major losses at any one of its 10 largest members. RISDIC also neglected standard regulatory practices in supervising member institutions. Adequate deposit insurance rests on several fundamentals, among them diversification, independent supervision, disclosure of weaknesses, and adequate reserves; RISDIC managed to delay but not avoid the consequences of neglecting these principles.
