Credit Rating Agency Ratings History Data
Under SEC Regulation 17g-7, Nationally Recognized Statistical Rating
Organizations (NRSRSOs) are required to report their historical rating
assignments, upgrades, downgrades and withdrawals since 2010. The files
must be updated monthly, formatted in XBRL and posted to each rating
agency's website. Rating data are generally reported on a one year
delay.
Because most researchers are unfamiliar with XBRL and cannot easily
locate the history files, this valuable resource has seen limited use.
On this web page, we provide histories from multiple agencies
converted to CSV format - which may be directly loaded into Microsoft
Excel or Access.
The files linked below are named to denote the date provided, rating
agency name and asset category.
