Abstract:Prior studies have provided evidence that outside pressure can affect howcredit rating agencies (CRAs) assign ratings. In this paper, we examine theimpact of a previously unexplored type of pressure on CRAs’ ratings: investors’demand. Exploiting the exogenous and sharp increase in investors’ demand forcorporate bonds rated A-in 2013 caused by the Federal Reserve’s asset purchase program;we find that S&P upgraded abnormally more BBB+ firms to the A- category inresponse to investors’ demand. To validate our conclusion, we exclude severalalternative explanations. The abnormal upgrade was not observed among firmswith ratings adjacent to BBB+, and was not offset by the downgrade in the sameand subsequent periods. S&P’s disclosure of new rating criteria in 2013cannot rule out the abnormality of the upgrade. In addition, the abnormalupgrade can neither be justified by changes in the upgraded firms’ financialperformance or ability to pay off debt. Further tests show that the marketconsidered the upgraded BBB+ bonds as riskier than other A- bonds and pricedthe upgraded BBB+ bonds similarly with other BBB+ bonds.
