We examine the marginal impact of Fitch rating on the yields at issuance of industrial and utility bonds rated by both Moody's and S&P. We find that Fitch ratings reduce the yield premiums on information opaque bond issues. The finding is robust even when a Fitch rating exactly equals the average of the two major ratings. However, for non-opaque bonds, an additional rating from Fitch has no impact on bond yields. We measure opacity in two ways: split ratings and an index of commonly used proxies for opacity. We estimate that a Fitch rating reduces the opacity premium on informational opaque bond issues proportionally by 30% to 40%, or 9-14 basis points. When ratings are split and the opacity levels are high, a Fitch rating has the largest reduction in bond yields.
