Rating action

Scope Ratings GmbH (Scope) has affirmed the AAA rating on the Norwegian mortgage covered bonds (obligasjoner med fortrinnsrett) issued by Rogaland Sparebank Boligkreditt AS (RSBB). The Outlook is Stable.

Key rating drivers

Covered bond rating anchor: A-. The issuer rating is the starting point of the covered bond rating. It reflects that RSBB, a wholly owned subsidiary, is fully aligned with ratings of Rogaland Sparebank. Through the issuance of covered bonds, RSBB provides secured funding for its parent. Scope expects it to benefit from full support from its parent in case of need. (see detailed rating report here)

Governance support (plus up to five notches). This rating uplift reflects the high likelihood of covered bonds being maintained as a going concern funding instrument in the event of regulatory action in the issuer or its parent as well as a smooth transition from the first (issuer) to the second recourse (cover pool) if needed. It consists of three notches from our resolution regime and systemic importance assessment and two notches from Scope’s legal framework and structural support assessment.

Scope’s legal framework and structural support analysis for RSBB’s covered bonds considers: 1) the cover pool’s valid segregation from the insolvency estate of the issuer in case of an insolvency; 2) the very high likelihood of bond payments continuing after insolvency; 3) the strong legal and programme specific asset eligibility and risk management principles; 4) that enhancements to the covered bond programme remain available after an insolvency of the issuer; and 5) the strong regulatory oversight specifically for Norwegian covered bonds. (ESG factor)

The resolution regime and systemic importance assessment considers: 1) the existence of statutory provisions (Bank Recovery and Resolution Directive) that protect the covered bonds against regulatory actions; 2) the strength of statutory provisions including their exemption from being bailed-in; 3) high systemic importance of Norwegian covered bonds but the low to moderate systemic importance of RSBB as a covered bond issuer; and 4) Norway’s strong proactive stakeholder community. (ESG factor)

Cover pool support (plus up to three notches). This rating uplift reflects the impact of the second recourse. It considers the programmes cover pool complexity (CPC) risk category of ‘Low’ which allows for an additional cover pool supported uplift of up to three notches. (ESG factor). An overcollateralisation (OC) of 5.0% is sufficient to support the current AAA rating. An OC of 7.0% would shield the current rating against a one-notch issuer downgrade.

This OC reflects:

• Credit risk – granular seasoned and domestic mortgages. The covered bonds are covered by a mortgage cover pool comprising granular, well-seasoned, domestic, residential, mostly owner-occupied cover assets with a (indexed) loan-to-value ratio of about 54.1%. We have established a default distribution which is defined by an annual average default probability of 64bps and a coefficient of variation of 60.0%.
   
• Market risk – No FX and interest mismatches. The programme’s assets and bonds are NOK-denominated and floating rate. However, the programme is exposed to maturity mismatches as reflected by the unmatched profiles (weighted average scheduled life of the assets of 12.6 years compared to 4.4 years of the covered bonds (extended)). The covered bonds are most sensitive to low prepayment (1%) together with an increasing interest rate environment (up to 9%).

One or more key drivers of the credit rating action are considered an ESG factor.

Outlook and rating sensitivities

The Stable Outlook on the RSBB’s covered bonds reflects Scope’s view on the expected rating stability of the issuer and no material changes to either governance or cover pool support factors.

Upside scenarios are not applicable as the ratings are the highest achievable.

The downside scenarios for the ratings and Outlooks are (individually or collectively):

• An issuer rating downgrade by three notches
   
• A reduction in the governance support uplift by three notches
   
• A deterioration in the programme’s interplay between complexity and transparency that worsens Scope’s CPC assessment and reduces the number of notches from cover pool support
   
• Available or committed OC falling below the rating-supporting level

Environmental, social and governance (ESG) factors

Governance is a key rating driver. For more detail, please refer to ‘governance support’ and ‘cover pool support’ (CPC assessment) under the ‘key rating drivers’ section above.

Quantitative analysis and assumptions

For its quantitative analysis Scope applied assumptions as laid down in the covered bond methodology.

Stress testing
No stress testing was performed.

Cash flow analysis
The Credit Rating uplift is based on a cash flow analysis using Scope Ratings’ covered bond model (Covered Bonds Expected Loss Model version 1.2). The model applies Credit Rating distance-dependent stresses to scheduled cash flows to simulate the impact of increasing credit and market risks. The outcome of the analysis is an expected loss rate and an expected weighted average life for the instruments based on the generated cash flows.
