Morningstar DBRS Downgrades Credit Ratings on Banca Carige S.p.A. Covered Bonds (OBG - Mortgages - Programme 1) to AA (low)

DBRS Ratings GmbH (Morningstar DBRS) downgraded its credit ratings on the obbligazioni bancarie garantite (OBG; the Italian legislative covered bonds) issued under the EUR 5,000,000,000 Banca Carige S.p.A. Covered Bonds Programme (the Programme) to AA (low) and removed the credit ratings from Under Review with Negative Implications (UR-Neg.), where they were placed on 17 November 2023.

This credit rating action reflects the interest rate increase that has occurred since the 2022 annual review, which affects the projected liquidation value of the fixed-rate portion of the cover pool (CP) following the assumed default of the reference entity (RE), as well as a change in the CP composition, which is now more significantly represented by fixed-rate loans: 80.8% of the total CP compared with 58.8% as of the previous cut-off date.

Morningstar DBRS’ review also considers a possible evolution in the composition of the CP, in light of further information provided by the Issuer on recent residential loans origination.

As of the date of this press release, there were 12 series of OBG outstanding under the Programme, totalling an outstanding nominal amount of EUR 1.9 billion. The series are all guaranteed by Carige Covered Bond S.r.l. (the Guarantor).

The credit ratings reflect the following analytical considerations:
-- A Covered Bonds Attachment Point (CBAP) of A (low), which is the Long Term Critical Obligations Rating of BPER Banca S.p.A. (BPER). BPER is the Issuer and RE for the Programme. Morningstar DBRS classifies Italy as a jurisdiction in which CBs are a particularly important funding instrument and deems the cover pool (CP) strategic for the core activity of the Issuer.
-- A Legal and Structuring Framework (LSF) Assessment of “Adequate” associated with the Programme.
-- A Cover Pool Credit Assessment (CPCA) of BBB, which is the lowest CPCA in line with the final LSF-Implied Likelihood (LSF-L).
-- An LSF-L of A (high).
-- A one-notch uplift on the LSF-L for good recovery prospects.
-- A committed minimum overcollateralisation (OC) of 34%, and the 45.0% OC to which Morningstar DBRS gives credit, equal to the minimum level observed in the past 12 months, adjusted by a scaling factor of 0.85.
-- The sovereign rating on the Republic of Italy, rated BBB (high) with a Stable trend by Morningstar DBRS, as of the date of this press release.

Morningstar DBRS analysed the transaction using its European Covered Bond Cash Flow tool. The main assumptions focused on the timing of defaults and recoveries of the assets, interest rate stresses, and market value spreads to calculate liquidation values on the CP.

Everything else being equal, a one-notch downgrade of the CBAP would lead to a two-notch downgrade of the LSF-L, resulting in a two-notch downgrade of the CB credit ratings.

In addition, all else remaining equal, the credit ratings on the CBs would be downgraded if any of the following occurred: (1) the CPCA was downgraded below BBB; (2) the quality of the CP and the level of OC were no longer sufficient to support a one-notch uplift for good recovery prospects; (3) the relative amortisation profiles of the OBG and the CP were to move adversely; (4) the LSF assessment associated with the Programme was downgraded; (5) volatility in the financial markets caused the currently estimated market value spreads to increase, or (6) the sovereign rating on the Republic of Italy was downgraded below BBB (high).

BNP Paribas, Italian branch acts as the account bank for this transaction. Based on Morningstar DBRS’ private rating on the account bank and the replacement provisions included in the transaction documentation, Morningstar DBRS considers the risk associated with such counterparty to be consistent with the credit ratings assigned, in accordance with its “Legal Criteria for European Structured Finance Transactions” methodology and “Global Methodology for Rating and Monitoring Covered Bonds”.

The total outstanding amount of OBG under the programme is currently EUR 1.9 billion. As at 31 December 2023, the balance of the CP totalled EUR 2.9 billion of residential loans (96.7% of the total pool balance) and commercial loans (3.3%) plus EUR 104 million of cash, resulting in a total OC of 53.0%.

The CP comprised 32,895 mortgage loans originated by a network of banks that were part of the Banca Carige Group.

As of 31 December 2023, the weighted-average current loan-to-value ratio of the mortgages was 53.0% with an average seasoning of 4.4 years. The assets securing the loans in the CP were mainly distributed in the Italian regions of Liguria (21.6% of the loan balance), Lombardy (19.4%), and Emilia-Romagna (10.5%).

The CP comprised fixed-for-life loans (81.5% by outstanding balance) and floating-rate loans (18.5%). The floating-rate mortgage loans are indexed to different plain-vanilla indices and reset at different dates.

In comparison, 100% of the liabilities pay a fixed rate.

The resulting interest rate risk has been considered in Morningstar DBRS’ cash flow analysis.

All CP assets and OBG are denominated in euros. As such, investors are not currently exposed to any foreign-exchange risk.

The weighted-average life (WAL) of the CP is 9.9 years whereas the WAL of the OBG, as of the date of this press release, was 4.0 years, taking into account the expected maturities. The resulting asset-liability maturity mismatch is mitigated by the 15-month maturity extension in case of an Issuer event of default and by the OC. Only Series 646 and Series 653 feature 12-month maturity extensions.

Morningstar DBRS assessed the LSF related to the Programme as “Adequate”, according to its rating methodology. For more information, please refer to the Morningstar DBRS commentary, “Italian Obbligazioni Bancarie Garantite Legal and Structuring Framework”, which is available on https://www.dbrsmorningstar.com.

Morningstar DBRS’ credit ratings on the outstanding CB series address the credit risk associated with the identified financial obligations in accordance with the relevant transaction documents. The associated financial obligations are the related interest payment amounts and the related principal amount.

Morningstar DBRS’ long-term credit ratings provide opinions on risk of default. Morningstar DBRS considers risk of default to be the risk that an issuer will fail to satisfy the financial obligations in accordance with the terms under which a long-term obligation has been issued.
