A common belief held among researchers and policymakers is that regulatory reliance has inflated market demand for credit ratings, despite ratings’ decreasing informational value. Advances in information technology, coupled with reputation losses following the subprime crisis, renew the question of whether investors still rely on ratings to assess credit risk. Moody’s 2010 municipal rating scale recalibration, which was unrelated to changing issuer fundamentals, reveals that ratings still matter to investors and to issuers – apart from any regulatory implications. Our results commend improved disclosure to mitigate mechanistic reliance on ratings and inefficiencies due to rating standards that vary across asset classes.
