PS17003_Suitability-of-external-agency-ratings-for-rating-in-country-bank-borrowers

Project goal: Given the considerations employed by the rating agencies in producing their ratings (data, methodology, overlays, adjustments, floors, seniority, etc…), should the bank’s lending to the rated borrowers use the ratings and PDs published by the agencies, or should the agencies’ ratings/PDs be adjusted due to the fact that the bank faces different level of risk compared to the intended consumers of rating agencies’ ratings by virtue of the comparative domicile/seniority/contract/legal environment? If they should be adjusted, how could this be undertaken? The answer will likely differ on the type of the borrower (sovereign, bank, non-bank financial institution, large corporate), the industry of the borrower and local versus in-country business.
