DBRS Morningstar Takes Rating Actions on 14 U.S. RMBS Transactions
RMBSDBRS, Inc. (DBRS Morningstar) reviewed 114 classes from 14 U.S. residential mortgage-backed security (RMBS) transactions. Of the 114 classes reviewed, DBRS Morningstar confirmed 110 ratings, upgraded three ratings, and discontinued one rating.
The rating confirmations reflect asset performance and credit-support levels that are consistent with the current ratings. The rating upgrades reflect positive performance trends and increases in credit support sufficient to withstand stresses at their new rating levels. The discontinuation reflects full repayment of principal to bondholders.
The pools backing the reviewed RMBS transactions consist of -Prime, Alt-A, Option-Adjustable-Rate-Mortgage, Scratch and Dent, Second-Lien, Reperforming, and Subprime collateral.
The ratings assigned to the securities listed below differ from the ratings implied by the quantitative model. DBRS Morningstar considers this difference to be a material deviation; however, in this case, the ratings on the subject securities may either reflect additional seasoning being warranted to substantiate a further upgrade or certain structural features that are not fully captured in the quantitative model output.

CORONAVIRUS IMPACT
The Coronavirus Disease (COVID-19) pandemic and the resulting isolation measures caused an immediate economic contraction, leading to sharp increases in unemployment rates and income reductions for many consumers. DBRS Morningstar saw increases in delinquencies for many RMBS asset classes, shortly after the onset of the pandemic.
Such mortgage delinquencies were mostly in the form of forbearances, which are generally short-term payment reliefs that may perform very differently from traditional delinquencies. At the onset of the pandemic, the option to forebear mortgage payments was widely available, and it drove forbearance to a very high level. When the dust settled, coronavirus-induced forbearance in 2020 performed better than expected, thanks to government aid and good underwriting in the mortgage market in general. Across nearly all RMBS asset classes, delinquencies have been gradually trending down in recent months as the forbearance period comes to an end for many borrowers.
In connection with the economic stress assumed under its moderate scenario (see “Global Macroeconomic Scenarios: June 2021 Update,” published on June 18, 2021), DBRS Morningstar may assume higher loss expectations for pools with loans on forbearance plans.
