DBRS Morningstar Confirms AA (low) Ratings on Banca Nazionale del Lavoro S.p.A. Covered Bonds (OBG - Mortgages)

DBRS Ratings GmbH (DBRS Morningstar) confirmed its AA (low) ratings on the Obbligazioni Bancarie Garantite (OBG; the Italian legislative covered bonds) issued under the Banca Nazionale del Lavoro S.p.A. Covered Bonds Programme (the Programme). This rating action follows the completion of a full review of the Programme.

Concurrently, DBRS Morningstar discontinued its AA (low) ratings on Series 6 (ISIN IT0005123507) and Series 16 (ISIN IT0005416992), which were repaid on 28 July 2022.

As of the date of this rating action, there were five series of OBG under the Programme, totalling an outstanding nominal amount of EUR 11.1 billion. The series are guaranteed by Vela OBG S.r.l.

The ratings reflect the following analytical considerations:
-- A Covered Bonds Attachment Point (CBAP) of AA (low). Banca Nazionale del Lavoro S.p.A. (BNL) is the Issuer and the reference entity (RE) for the programme. There is no Critical Obligations Rating associated with the RE, but DBRS Morningstar classifies Italy as a jurisdiction for which covered bonds (CB) are a particularly important financing tool.
-- A Legal and Structuring Framework (LSF) Assessment of “Modest” associated with the Programme.
-- An LSF-Implied Likelihood (LSF-L) of AA (low).
-- No uplift for recovery prospects.
-- A level of overcollateralisation (OC) of 9.1% to which DBRS Morningstar gives credit, which is the minimum observed OC level over 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 DBRS Morningstar, as of the date of this rating action.

DBRS Morningstar 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, and interest rate stresses.

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 on the CB ratings.

BNL acts as the account bank for this transaction. Based on its rating and on the replacement provisions included in the documentation, DBRS Morningstar considers the risk of such counterparty to be consistent with the ratings assigned, in accordance with its “Legal Criteria for European Structured Finance Transactions” and “Rating and Monitoring Covered Bonds” methodologies.

BNL also acts as the cover pool (CP) swap counterparty. However, the swap documentation is not in line with DBRS Morningstar’s “Derivative Criteria for European Structured Finance Transactions” methodology and as a consequence, DBRS Morningstar did not give credit to the swaps in its analysis.

The total outstanding amount of OBG is currently EUR 11.1 billion. As at 30 September 2022, the CP was composed of EUR 15.1 billion of residential (92.0% of the loan balance), commercial (7.3%), and public sector (0.7%) mortgages plus EUR 451 million of cash, resulting in a total OC of 36.8%.

The weighted-average (WA) current loan-to-value ratio of the mortgages was 48.3% with an average seasoning of 4.8 years as at 30 September 2022. The assets securing the loans in the CP were mainly located in the Italian regions of Lazio (22.4% of the loan balance) and Lombardy (15.6%).

The CP comprised fixed-for-life loans (86.2% by outstanding balance) and floating-rate loans (13.8%). The floating-rate mortgage loans are indexed to different plain-vanilla indices and reset at different dates.

By comparison, 100% of the liabilities pay a floating rate linked to three-month Euribor. DBRS Morningstar considered the resulting interest and basis risks as unhedged in its 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 was 9.1 years as at 30 September 2022 whereas the WAL of the OBG, as of the date of this rating action, was 2.1 years, taking into account the expected maturities. The resulting asset-liability maturity mismatch is mitigated by the OC.

DBRS Morningstar has assessed the LSF related to the Programme as “Modest”, according to its “Rating and Monitoring Covered Bonds” methodology.
