Rating action

Scope Ratings has today affirmed its AAA ratings with a Negative Outlook on Deutsche Bank AG’s mortgage-covered bonds (Hypothekenpfandbriefe). Scope subsequently withdraws all ratings and Outlooks assigned to Deutsche Bank’s covered bonds for commercial reasons.

Rating rationale

Today’s ratings action reflects the ability of the cover pool to support a seven-notch uplift above Deutsche Bank’s issuer rating (BBB+/Negative). The Negative Outlook on the covered bonds mirrors the Outlook on the issuer.

Scope’s ratings of Deutsche Bank’s German mortgage-covered bonds incorporate the higher uplift provided by:

1. fundamental credit support factors, allowing for a six-notch uplift above the bank’s rating; and
    
2. cover pool support of seven notches reflecting available overcollateralisation which mitigates credit and market risks under stressed assumptions. Scope’s cover pool analysis is based on publicly available information and therefore only allows for an uplift which is one notch higher than fundamental credit support.

Following the rating affirmation, Scope has withdrawn all ratings and Outlooks on Deutsche Bank’s covered bonds.

Supportive legal framework and resolution regime provide six-notch credit differentiation

Fundamental credit support factors provide the covered bond ratings with a six-notch uplift above Deutsche’s issuer rating. Two notches of the uplift are driven by the agency’s analysis of the German legal covered bond framework; and four notches by the benefits of the resolution regime combined with the systemic importance of both the issuer and the product.

Germany’s legal covered bond framework meets all provisions relevant to establishing and maintaining a high-quality cover pool that remains available after potential issuer insolvency, supporting the two-notch uplift. The rating agency does not expect potential amendments made to comply with the European Commission’s covered bond harmonisation directive to impact this assessment.

The covered bond rating incorporates four additional notches of credit support for issuer- and country-specific benefits provided by the resolution regime and the systemic importance of covered bonds in Germany. This reflects: i) the covered bonds’ exclusion from a bail-in in the hypothetical scenario of the bank experiencing regulatory intervention; ii) Scope’s view on the bank’s resolvability, reflecting the ability of regulators to apply available resolution tools to the issuer’s liabilities and equity, combined with Deutsche Bank’s status as a globally systemically important bank; iii) the flagship status of German covered bonds, their importance to domestic banks as a refinancing tool and strong presence in investor portfolios; and iv) the active and combined efforts of the domestic stakeholder community to maintain German covered bonds as a fixed income instrument of the highest quality.

Cover pool support as primary rating driver but uplift limited

Deutsche Bank’s covered bond ratings incorporate one notch of cover pool support on top of fundamental credit support. Scope analysed the covered bond programme’s credit and cash flow characteristics based on public information as of 30 June 2018.

Limited credit risk in the cover pool and cash flow risks contained

The largest part of the EUR 9.9bn cover pool comprises residential mortgage loans (62%) followed by commercial assets (36.5% also including 25.1% of multifamily housing), as well as 2.8% of substitute assets. The cover pool is highly granular with 72% of the exposures below EUR 300,000 and an average weighted loan-to-value ratio of a moderate 53.3%.

As of 30 June 2018, the covered bond programme benefits from overcollateralisation of 28.6% on a nominal basis. Based on the most recent information, Scope has established that a minimum 21.1% of overcollateralisation supports the cover pool-based rating uplift. Scope observes a maturity mismatch between the assets and covered bonds of about two years (2.5 years based on a weighted average maturity). Interest rate risk is low as most assets and liabilities are fixed rate (98.8% and 94% respectively). There is no foreign-exchange risk as assets and liabilities are fully euro-denominated.

Quantitative analysis and key assumptions

Scope established projections of cover pool default, based on comparable German cover pools rated by the agency, using an inverse Gaussian distribution. The consolidated segment-specific default and recovery assumptions used in the analysis consist of a weighted average mean default rate of 10% for the residential sub-portfolio and 20% for the commercial assets with a coefficient of variation of 60% and 50% respectively.

Scope applied a weighted average stressed recovery rate of 52%. This translates into a mean loss rate of 6.0%. For the asset sale, Scope added to its discount rate a blended liquidity premium between 125 bps for substitute assets and up to 300 bps for commercial loans. Servicing fees were assumed to be at 23 bps. In the stressed cash flow analysis, Scope used a low prepayment rate scenario (0%) together with a rising interest rate scenario after the second year.

Scope analysed the substitute assets accounting for 2.8% of the cover pool under a portfolio analysis framework to estimate the sub-portfolio’s default characteristics. The non-parametric distribution can be described with a mean default rate of 1.5% and a coefficient of variation of 323%.

Rating-change drivers (not applicable)

Following the affirmation of Deutsche Bank’s German mortgage-covered bonds, the ratings have been withdrawn.

Cash flow analysis
In order to determine the cover pool supported rating uplift, Scope performed a cash flow analysis to establish an expected loss for the covered bonds. The cash flow analysis uses the scheduled cash flows of the cover assets and covered bonds as a starting point. Scope applies rating distance-dependant stresses to simulate the impact of increasing credit and market risks to these cash flows. The cash flow analysis also includes the impact of stressed asset sales or other variables such as changing prepayment speeds or servicing costs.

Stress testing
No stress testing was performed.

Methodology
The methodologies used for this rating and rating outlook were the Covered Bond Rating Methodology and Scope’s General Structured Finance Rating Methodology (for the translation of the expected loss into ratings). The methodologies are available on www.scoperatings.com.
