DBRS Morningstar Assigns AAA Rating to BMO Global Registered Covered Bonds Series CBL33

Covered Bonds
April 04, 2023

DBRS Limited (DBRS Morningstar) assigned a rating of AAA to the Covered Bonds, Series CBL33 (Series CBL33) issued under the Bank of Montreal (Global Registered Covered Bond Program) (the Program). Series CBL33 (EUR 2.0 billion) has a coupon rate of 3.375% and a maturity date of July 4, 2026. All covered bonds issued under the Program (the Covered Bonds) rank pari passu with each other and are currently rated AAA by DBRS Morningstar.

The AAA ratings are based on the following analytical considerations:

-- A Covered Bond Attachment Point of AA, which is the Long-Term Senior Debt rating of the Bank of Montreal (BMO). BMO is the Reference Entity for the Program.
-- A Legal and Structuring Framework (LSF) assessment of Strong associated with the Program.
-- A Cover Pool Credit Assessment of ‘A’.
-- An LSF-Implied Likelihood (LSF-L) of AAA.
-- While not currently applicable, based on the recovery notching scale, up to two notches’ uplift from the LSF-L for high recovery prospects is possible.
-- A level of overcollateralization (OC) of 7.0% (based on the Asset Percentage of 93.5% as at February 28, 2023) to which DBRS Morningstar gives credit.

DBRS Morningstar considered the following factors in its analysis described above:

(1) The Covered Bonds are senior unsecured direct-deposit obligations of BMO and are excluded from Canada’s bank recapitalization (bail-in) regime.

(2) In addition to a general recourse to BMO’s assets, the Covered Bonds are supported by a diversified pool of first-lien conventional Canadian residential mortgages with a maximum loan-to-value (LTV) ratio of 80.0% at origination (the Cover Pool). The Cover Pool was approximately $42.5 billion as at February 28, 2023.

(3) The Covered Bonds benefit from several structural features, such as a reserve fund, when applicable, and rating thresholds for the swap counterparties, servicer, account bank, cash manager, and guaranteed deposit account provider.

(4) Upon a default by BMO, the final maturity date on the Covered Bonds can be extended for 12 months, which increases the likelihood that the Covered Bonds can be fully repaid.

(5) There is a specific covered bond legislative framework in Canada. In addition, the contractual obligations of the transaction parties are supported by Canada’s well-developed commercial and bankruptcy laws, the satisfactory opinions provided by legal counsel to BMO, and a generally creditor-friendly legal environment in Canada.

Despite these strengths, the ratings on the Covered Bonds could face the following challenges:

(1) A weakened housing market in Canada could result in higher defaults and/or lower recoveries than the assumptions used in the Cover Pool’s credit assessment. This risk is significantly reduced by the home equity available in relation to the portfolio’s weighted-average LTV ratio of 48.9% (based on indexed property value) reported by BMO as at February 28, 2023.

(2) BMO may need to add mortgages to maintain the Cover Pool, incurring substitution and potential credit deterioration risk. These risks are mitigated by the ongoing monitoring of the Cover Pool to ensure that the OC available is commensurate with the ratings of the Covered Bonds. Based on the latest review of the Cover Pool, DBRS Morningstar considers 3.0% OC, corresponding to the Regulatory OC Minimum, to be commensurate with the AAA ratings.

(3) There is an inherent liquidity gap between the scheduled repayments of the Covered Bonds and the repayment of the underlying mortgage loans over time. This risk is mitigated by OC, the buildup of a reserve fund if BMO is not rated at least A (low) or R-1 (middle), and the 12-month maturity extension upon default by BMO.

BMO is one of Canada’s largest banks as measured by assets as at January 31, 2023, with assets of $1,145.7 billion and total equity of $74.9 billion. It is the initial servicer of the mortgages in the Cover Pool.
