Deep Dive – Moody’s Recent RMBS Rating Action

On April 15, 2020 Moody’s placed 404 classes (bond) of legacy US RMBS on review for downgrade, and downgraded and placed on review for further downgrade 48 classes for a total of 441 classes impacted. The 48 downgrades ranged from 1 to 4 notches. All the classes downgraded are now rated Baa3, the lowest investment grade rating. Below is a table summarizing the downgrade activity by bond type and collateral type and the number of notches downgrade. 92% of the bonds downgraded were subordinate bonds. 69% of this population were subprime bonds, of which 31% were downgraded 4 notches.

According to Moody’s, the rating rationale is the heightened risk of interest loss due to the slowing US economic activity and increased levels of unemployment. Moody’s states that they “considered the sensitivity of the bonds’ rating to the magnitude of projected interest shortfalls under a baseline and stressed scenarios”. Later in the press release they state that “Moody’s did not use any models, or loss or cash flow analysis, in its analysis” and “Moody’s did not use any stress scenario simulations in its analysis”.
