To the extent authorized by federal law, the Commissioner may waive any applicable federal limit on concentration of deposits if the Commissioner finds that the waiver promotes the availability of financial services or is otherwise in the public interest. The Commissioner may, by regulation, establish standards for granting a waiver pursuant to this section and the procedure for requesting a waiver. In making a decision to waive such a federally imposed limit, the Commissioner shall apply a standard that does not discriminate in purpose or effect against out-of-state depository institutions.
