BANKING

Curbs Placed on Bank of Boston: Regulators placed Bank of Boston Corp., which has been hurt by New England’s commercial real estate slump, under tight operating restrictions. The holding company is forbidden to pay dividends to stockholders without regulatory approval. Within 60 days, Bank of Boston must submit a plan to keep its capital reserves and the capital reserves of subsidiary banks in compliance with minimum federal standards. Capital acts as a cushion, absorbing losses. When it is gone, the institution is declared insolvent and the government’s deposit insurance fund must pay for additional losses.
