DBRS Morningstar Places Ratings on 24 UK RMBS Transactions Under Review with Positive Implications Following Update to European RMBS Insight: UK Addendum

RMBS

October 04, 2022

DBRS Ratings Limited (DBRS Morningstar) placed the ratings on 110 tranches in 24 UK residential mortgage-backed securities (RMBS) transactions Under Review with Positive Implications.

KEY RATING DRIVERS AND CONSIDERATIONS
On 16 September 2022, DBRS Morningstar finalised its updated “European RMBS Insight: UK Addendum” (the Methodology), superseding the prior version published on 27 October 2021. The Methodology presents the criteria for which UK RMBS ratings, and, where relevant, UK covered bonds ratings, are assigned and/or monitored.

The changes to the Methodology include updates to the market value decline assumptions in the UK, which are now derived using a base year of 2017, as opposed to 2002 previously, and updates to house price indexation to reflect data through Q4 2021. For more details, see the following press release:
https://www.dbrsmorningstar.com/research/402865/dbrs-morningstar-publishes-final-european-rmbs-insight-uk-addendum.

As a result of the application of the Methodology, DBRS Morningstar placed the ratings on the aforementioned tranches Under Review with Positive Implications. DBRS Morningstar also rates the Class A notes issued in each transaction in addition to other classes of notes rated AAA (sf), but did not place these classes of notes Under Review.

ENVIRONMENTAL, SOCIAL, GOVERNANCE CONSIDERATIONS
DBRS Morningstar considers the help-to-buy (HTB) scheme applicable to a proportion of the portfolio in Genesis Mortgage Funding 2022-1 plc, Finsbury Square 2019-3 plc, Finsbury Square 2020-1 plc, Gemgarto 2021-1 Plc, Tower Bridge Funding 2021-1 plc, Tower Bridge Funding 2021-2 plc and Tower Bridge Funding No. 4 PLC to be a relevant social factor (social impact of products and services) as outlined in the “DBRS Morningstar Criteria: Approach to Environmental, Social, and Governance Risk Factors in Credit Ratings”. The HTB scheme is credit negative, but DBRS Morningstar does not consider this to be a significant social factor given the generally limited exposure to HTB loans in these transactions.

In the remaining transactions, there were no Environmental/Social/Governance factors that had a significant or relevant impact on the credit analysis.

A description of how DBRS Morningstar considers ESG factors within the DBRS Morningstar analytical framework can be found in the DBRS Morningstar Criteria: Approach to Environmental, Social, and Governance Risk Factors in Credit Ratings at https://www.dbrsmorningstar.com/research/396929/dbrs-morningstar-criteria-approach-to-environmental-social-and-governance-risk-factors-in-credit-ratings (17 May 2022).

Notes:
All figures are in British pound sterling unless otherwise noted.

The principal methodologies applicable to the ratings are the “Master European Structured Finance Surveillance Methodology” (19 May 2022), https://www.dbrsmorningstar.com/research/397033/master-european-structured-finance-surveillance-methodology, and the “European RMBS Insight: UK Addendum” (16 September 2022), https://www.dbrsmorningstar.com/research/402864/european-rmbs-insight-uk-addendum.

DBRS Morningstar is undertaking a review and will remove the ratings from this status as soon as it is appropriate.
