DBRS Morningstar Takes Rating Actions on 78 U.S. RMBS Transactions

DBRS, Inc. (DBRS Morningstar) reviewed 559 classes from 78 U.S. residential mortgage-backed security (RMBS) transactions. Of the 559 classes reviewed, DBRS Morningstar upgraded 40 ratings, confirmed 222 ratings, and discontinued 297 ratings.

The rating upgrades reflect positive performance trends and increases in credit support sufficient to withstand stresses at their new rating levels. The rating confirmations reflect asset performance and credit-support levels that are consistent with the current ratings. The discontinued ratings reflect the transactions exercising their clean-up call option or the full repayment of principal to bondholders.

The pools backing the reviewed RMBS transactions consist of nonqualified mortgage, re-performing, prime, single family rental, agency credit, and subprime mortgage collateral.

The ratings assigned to the securities listed below differ from the ratings implied by the quantitative model. DBRS Morningstar considers these differences material deviations; however, in these cases, the ratings on the subject securities may reflect additional seasoning being warranted to substantiate a further upgrade or actual deal or tranche performance not being fully reflected in the projected cashflows/model output.

CORONAVIRUS DISEASE (COVID-19) IMPACT
The coronavirus 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 coronavirus.

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. Because the option to forbear mortgage payments was so widely available at the onset of the pandemic, , it drove forbearances to a very high level. When the dust settled, coronavirus-induced forbearances 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 baseline scenario (see “Baseline Macroeconomic Scenarios For Rated Sovereigns March 2022 Update,” published on March 24, 2022), DBRS Morningstar may assume higher loss expectations for pools with loans on forbearance plans.

The rating actions are the result of DBRS Morningstar’s application of its U.S. RMBS Surveillance Methodology, published on February 21, 2020.
