DBRS Ratings GmbH (DBRS Morningstar) upgraded its ratings on the Obrigações Hipotecárias (OH; the Portuguese legislative covered bonds) issued under Caixa Geral de Depósitos, S.A.’s (CGD or the Issuer) covered bond programme (the Programme) to AA (high) from AA.
This rating action reflects the upgrade on the Issuer’s Long Term Critical Obligations Rating (COR) to “A” from A (low) on 24 May 2023. CGD’s COR is the Covered Bond Attachment Point (CBAP) of the Programme.
As of the date of this press release, the total amount of bonds outstanding under the Programme was EUR 3 billion spread across two series, both retained.
The ratings are based on the following analytical considerations:
-- A CBAP of “A”, which is the Long Term Critical Obligation Rating on CGD. CGD is the Issuer and the Reference Entity (RE) for the Programme. DBRS Morningstar considers the assets in the Programme to be strategic to the core activity of the RE.
-- A Legal and Structuring Framework (LSF) Assessment of “Adequate” assigned to CGD’s OH programme.
-- A cover pool credit assessment (CPCA) of BBB, being the lowest CPCA in line with the LSF-L.
-- An LSF-Implied Likelihood (LSF-L) of AA (low).
-- A two-notch uplift for high recovery prospects.
-- A level of overcollateralisation (OC) of 28% to which DBRS Morningstar gives credit, which is the level of OC the Issuer commits to maintain as stated in its quarterly investor reports. This level is not subject to haircut, as DBRS Morningstar considers it to be persistent based on historically observed levels.
-- The sovereign rating on the Republic of Portugal, rated A (low) with a Stable trend by DBRS Morningstar, as of the date of this press release.
DBRS Morningstar analysed the transaction with its European Covered Bond Cash Flow tool. The main assumptions focused on the timing of defaults, recoveries of the assets and interest rate stresses, as well as market value spreads to calculate liquidation values on the cover pool (CP).
Everything else equal, a one-notch downgrade of the CBAP would lead to a one-notch downgrade of the LSF-L, resulting in a one-notch downgrade of the covered bonds (CBs) rating. In addition, the ratings on the OH would be downgraded if any of the following occurred: (1) the sovereign rating on the Republic of Portugal was downgraded below A (low); (2) the CPCA was downgraded below BBB; (3) the quality of the CP and the level of OC were no longer sufficient to support a two-notch uplift for high recovery prospects; (4) the relative amortisation profile of OH and CP moved adversely; (5) the LSF Assessment associated with the Programme was downgraded; or (6) volatility in the financial markets caused the currently estimated market value spreads to increase.
As of March 2023, the total CP balance was EUR 3.94 billion, including EUR 3.91 billion of mortgages and EUR 35.58 million of eligible securities and cash. There are currently EUR 3 billion in CBs outstanding under CGD’s OH Programme, giving an estimated total OC of 31.4%.
As of March 2023, the mortgage CP comprised 76,944 residential mortgages granted to individuals with an average loan amount of EUR 50,774. The weighted-average (WA) unindexed loan-to-value ratio of the mortgages was 48.4% with a WA seasoning of 161.3 months. The CP was mainly distributed in Lisbon (37.1% by outstanding balance), northern Portugal (24.2%), and central Portugal (20.9%).
The majority of the loans in the CP (98.9%) pay a floating interest rate indexed to Euribor while 100% of the CBs are floating rate. The interest rate mismatch in this transaction is negligible, but DBRS Morningstar accounted for this in its analysis.
The CP assets and the OH are all denominated in euros. As such, investors are not currently exposed to any foreign exchange risk.
The DBRS Morningstar-calculated WA life of the mortgage assets is about 14.4 years based on a 0% prepayment rate, which is longer than the 4.2 years of WA life on the OH, not accounting for any maturity extension. The resulting asset-liability maturity mismatch is mitigated by the OC available, a liquidity cushion available to cover three months of interest payments on the bonds and a 12-month extendable maturity feature by which, should the Issuer default on its payment on the CBs at the respective expected maturity date, the CB maturities are automatically extended on a monthly basis up to 12 months.
