DBRS Morningstar Assigns AA (low) Rating to Banca Monte dei Paschi di Siena S.p.A. Covered Bonds (OBG – Mortgage Programme 1) Series 27

Covered Bonds
October 08, 2019

DBRS Ratings GmbH (DBRS Morningstar) assigned a rating of AA (low) to Series 27 of the Obbligazioni Bancarie Garantite (OBG; the Italian legislative covered bonds) issued under the Banca Monte dei Paschi di Siena SpA (BMPS or the Issuer) EUR 20,000,000,000 covered bond programme (BMPS OBG1 or the Programme) guaranteed by MPS Covered Bond S.r.l.

Series 27 is a EUR one billion fixed-rate bond, which pays a coupon of 0.875% per annum and matures on 8 October 2026. The extended maturity date is 8 October 2064.

Including Series 27, there are currently 13 outstanding series of OBG under the Programme that total a nominal amount of EUR 8.95 billion.

The rating is based on the following analytical considerations:
-- A Covered Bonds Attachment Point (CBAP) of BBB (low), which is the Long-Term Critical Obligations Rating of BMPS. BMPS is the Issuer and the Reference Entity for the Programme. DBRS Morningstar classifies the Republic of Italy (Italy; rated BBB (high) with a Stable trend by DBRS Morningstar) as a jurisdiction in which covered bonds 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 “Very Strong” associated with the Programme.
-- A Cover Pool Credit Assessment (CPCA) of A (low), which is the lowest CPCA in line with the assigned LSF-Implied Likelihood (LSF-L).
-- An LSF-L of “A”.
-- A two-notch uplift on the LSF-L for high recovery prospects.
-- A level of overcollateralisation (OC) of 27.2% to which DBRS Morningstar gives credit, which is the minimum level observed in the last 12 months adjusted by a scaling factor of 0.85, and an Issuer-committed asset percentage of 83.0%, corresponding to a level of committed OC of 20.5%.

The transaction was analysed with DBRS Morningstar’s European Covered Bond Cash Flow Tool. The main assumptions focused on the timing of defaults and recoveries of the assets and interest rate stresses. In accordance with the DBRS Morningstar “Rating and Monitoring Covered Bonds” methodology, no forced asset liquidations were analysed for this transaction, given the conditional pass-through structure. DBRS Morningstar assumed several prepayment scenarios, ranging between a 1% and 20% prepayment rate.

Everything else being equal, a one-notch downgrade of the CBAP would lead to a one-notch downgrade of the covered bonds rating. In addition, the ratings would be downgraded if any of the following were to occur: (1) the quality of the CP and the level of OC were no longer sufficient to support a two-notch uplift for high recovery prospects, (2) the LSF Assessment associated with the Programme were downgraded to “Average” or below or (3) the CPCA were downgraded below A (low).

BMPS OBG1 has a conditional pass-through structure. If the guarantee is enforced, the Guarantor is not contractually bound to pursue a forced asset sale of the CP in a distressed market environment. Notwithstanding this, the Guarantor can still attempt to liquidate the assets with a view to meeting its payment obligations on the pass-through series and on the earliest maturing covered bonds. In so doing, the Guarantor shall attempt to maintain the Programme’s OC proportionally to all asset sales. Additionally, the Programme documentation provides for the sale of the assets to take place only as long as the Amortisation Test (which sets the OC to a level of at least 75% of the OC resulting from the Asset Percentage used on the last Test Calculation Date preceding the service of a Guarantee Enforcement Notice) is complied with before and after the sale. Should the Amortisation Test be breached, all series switch to pass-through payment on a pari passu and pro rata basis. DBRS Morningstar did not account for stresses on forced asset sales in its analysis because the Guarantor is not obliged to liquidate the assets.

The Bank of New York Mellon (Luxembourg) S.A./NV, Milan Branch (rated AA with a Positive trend by DBRS Morningstar) and The Bank of New York Mellon S.A./NV, London branch (rated AA with a Positive trend by DBRS Morningstar) have replaced BMPS in its capacity as the Italian and English account banks, respectively. DBRS Morningstar considers the risk arising from the exposure to these entities to be consistent with the ratings assigned to the OBG, as described in DBRS Morningstar's "Legal Criteria for European Structured Finance Transactions" methodology. Commingling and set-off risk are mitigated by the computation of such risks in the asset coverage tests.

As of June 2019, the total CP balance was EUR 12.14 billion, including EUR 11.29 billion of mortgages and EUR 847.66 million of cash. Including Series 27, there currently are EUR 8.95 billion covered bonds outstanding under BMPS OBG1 for a total OC of 32.0%, net of commingling and set-off amounts.

As of June 2019, the mortgage CP comprised 140,890 mortgages backed by residential properties located in Italy. All mortgages were originated by either BMPS or affiliated groups. A small portion of the pool, 7.2% by loan balance as of the end of May 2019, was granted to individuals not classified as SAE 600 by the Bank of Italy. DBRS Morningstar received separate default data for these borrowers and calculated a stressed default rate.

As of June 2019, the weighted-average (WA) current loan-to-value of the mortgages was 49.2% with a WA seasoning of 7.1 years. The CP is well distributed across Italy with the highest concentrations in Tuscany (18.8% by outstanding loan balance), Lazio (15.5%) and Lombardy (14.0%).

The CP comprises fixed-rate loans (24.1% by outstanding balance), floating-rate loans (73.2% by outstanding balance) and loans that have the option to switch to either a floating or fixed rate (2.8% by outstanding balance). The floating-rate mortgages are indexed to different plain vanilla bases and reset at different dates. Approximately 72.1% of OBG notional pays a fixed-rate coupon until the expected maturity, and if the maturity is extended, the relevant series becomes a pass-through series paying a floating rate plus a spread on a quarterly basis. DBRS Morningstar considered interest rate risk mismatch in its cash flow analysis.

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

As of 30 June 2019, the WA life of the CP was 9.8 years, which is longer than the 4.3 years WA life on the OBG (calculated as of today) when accounting for the expected maturity. This risk is mitigated by the long extendable maturity date, which falls 38 years after the maturity date.

DBRS Morningstar has assessed the LSF related to the BMPS OBG1 as “Very Strong” according to its rating methodology. For more information, please refer to DBRS Morningstar commentary “Italian Covered Bonds Legal and Structuring Framework Review,” available at

In DBRS Morningstar’s opinion, the change(s) under consideration do not require the application of the entire principal methodology. Therefore, DBRS focused on the cash flow analysis.
