The U.S. Securities and Exchange Commission has drafted a regulation that could require credit rating agencies to give more information about how they assign ratings.

The proposed rule also could require “nationally recognized statistical rating organizations” to avoid more types of potential conflicts of interest.

The SEC has posed many questions for commenters in a preamble to a copy of the draft rule, which appears today in the Federal Register.

In one place, the SEC asks whether rating agencies should use a symbol or report to distinguish ratings of insurers from other types of ratings.
