What Is an NRSRO?

A nationally recognized statistical ratings organization (NRSRO) is a credit rating organization that provides an assessment of the creditworthiness of a firm or financial instrument(s) and is registered with the Securities and Exchange Commission (SEC). Not all credit rating organizations are NRSROs. As of May 2018, there are ten NRSROs registered with the SEC. The SEC Office of Credit Ratings administers its rules relating to NRSROs.

Understanding NRSRO

Generally, to be considered a nationally recognized statistical ratings organization (NRSRO), the SEC must deem the agency to be "nationally recognized" in the U.S., and it must provide reliable and credible credit ratings. Also taken into consideration by the SEC are things like the size of the credit rating agency, operational capability, and the agency's financial resources. The credit ratings provided by NRSROs are used by the U.S. government in several regulatory areas and are also used as benchmarks by federal and state agencies. Investors also refer to ratings by NRSROs. Some examples of current nationally recognized statistical rating organizations include Moody's Investors Service Inc., S&P Global Ratings, Fitch Ratings Inc., and Morningstar Credit Ratings, LLC.
