DBRS Morningstar Takes Rating Actions on 18 U.S. RMBS Transactions

DBRS, Inc. (DBRS Morningstar) reviewed 550 classes from 18 U.S. residential mortgage-backed security (RMBS) transactions. Of the 550 classes reviewed, DBRS Morningstar upgraded 71 ratings, confirmed 464 ratings, discontinued four ratings, and maintained an Under Review with Negative Implications status for 11 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 cleanup call option or the full repayment of principal to bondholders. The Under Review with Negative Implications status reflects the negative impact of the Coronavirus Disease (COVID-19) pandemic on the bonds. For certain bonds, DBRS Morningstar maintained the Under Review with Negative Implications status amid the uncertainty in these transactions’ performance with respect to forbearance and delinquency trends.

The pools backing the reviewed RMBS transactions consist of Freddie Mac, Fannie Mae and prime 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 actual deal/tranche performance that is not fully reflected in the projected cash flows/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. Shortly after the onset of the pandemic, DBRS Morningstar saw an increase in the delinquencies for many RMBS asset classes.

Such mortgage delinquencies were mostly in the form of forbearances, which are generally short-term periods of payment relief that may perform very differently from traditional delinquencies. At the onset of the pandemic, the option to forebear mortgage payments was widely available, driving forbearances to an elevated level. When the dust settled, loans with coronavirus-induced forbearance in 2020 performed better than expected, thanks to government aid, low loan-to-value ratios (LTVs), and acceptable underwriting in the mortgage market in general. Across nearly all RMBS asset classes in recent months delinquencies have been gradually trending downward as forbearance periods come 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.
