Federal and state banking regulators closed First RepublicBank Corp.’s only remaining subsidiary bank, First RepublicBank Delaware. The Dallas-based bank holding company said the Delaware bank opened for business Monday but was unable to meet liquidity requirements Tuesday and was ordered closed. The holding company Monday sought protection from creditors under Chapter 11. That move followed last week’s closure by regulators of the company’s 40 Texas banks, which were turned over to NCNB Corp. of Charlotte, N.C.
