Q4 2018 Credit Commentary And A Look Ahead To 2019
The number of issuers seeking multiple ratings has declined since the financial crisis. Until the crisis, issuers often had debt ratings from two or more rating agencies. According to data collected by Municipal Market Advisors (MMA), issuers that were triple-rated (by Moody's, S&P and Fitch - data on Kroll is not able to be queried yet) declined steadily from 55% in 2007 to 34% through 2017. Viewed another way, by the end of Q3 2018 there were 1.91 ratings assigned per dollar par issued, down from 2.29 ratings assigned per dollar par issued in 2007. The par value of bonds that are rated by just one rating agency has grown to 25% from 21% in 2007. The trend is likely a function of municipalities' looking to reduce costs. Additionally, in the recent low-interest-rate environment with narrow credit spreads, fewer ratings on bonds have been sufficient to gain market acceptance, especially as investors chase yield. If credit spreads were to widen, a differentiation in yield might become visible among bonds with just one rating compared to those with two or more ratings, and this development could reverse the trend.
