US banking regulators took a first step on Tuesday on the road to replacing the use of private credit ratings to assess the soundness of banks, while also expressing nervousness about the transition. Under the new Dodd-Frank financial regulatory overhaul law, bank regulators over the next year will have to propose alternatives to the use of private credit ratings in their assessments of banks' capital levels.

One of the new offices, the Office of Complex Financial Institutions, was charged with managing the FDIC's new authority to liquidate or unwind large troubled financial companies. The other, the Division of Depositor and Consumer Protection, would focus on enforcing consumer protection and safe
