Bank of Nova Scotia Registered Global Covered Bond, Series CBL48 rated AAA by DBRS Morningstar

DBRS Limited (DBRS Morningstar) assigned a rating of AAA covered bonds, series CBL48 (series CBL48) issued under the Bank of Nova Scotia (Global Registered Covered Bond Program) (the Registered Program).

Series CBL48 (USD 1.5 billion) has a coupon rate of 3.186% and a maturity of June 3, 2025. All Covered Bonds issued under the Registered 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 senior long-term debt rating for The Bank of Nova Scotia (SNB). BNS is the reference entity for the recorded program.

An assessment of Strong’s legal and structuring framework (LSF) associated with the recorded program.

A credit rating of the cover pool of A (low).

An LSF implied probability (LSF-L) of AA (high).

A one-notch increase in LSF-L for high recovery prospects to reach the AAA odds.

An overcollateralization (OC) level of 5.5% (based on the percentage of assets of 94.8% at April 28, 2022) 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 bonds of BNS and are excluded from from Canada bank recapitalization regime (bail-in).

(2) In addition to a general use of SNB assets, the covered bonds are backed by a diversified portfolio of Canadian conventional residential first mortgages with a maximum loan-to-value (LTV) ratio of 80.0% at the origin (the Indoor swimming pool). The cover pool was approximately $65.4 billion like a April 28, 2022. Scotia Total Equity Plan (STEP) loans may have revolving, amortizing and non-amortizing loan portions secured by the same first lien. Only the depreciable portions of STEP loans are included in the Indoor swimming pool.

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

(4) In the event of default by the SNB, the final maturity date of the covered bonds can be extended by 12 months, which increases the likelihood that the covered bonds can be fully repaid.

(5) There is a specific legislative framework for covered bonds in Canada. In addition, the contractual obligations of the parties to the transaction are supported by from Canada well-developed commercial and bankruptcy laws, satisfactory advice provided by SNB legal advisers and a generally creditor-friendly legal environment in Canada.

Despite these strengths, covered bond ratings 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 by DBRS Morningstar in Pool cover Credit assessment. This risk is significantly reduced by the equity in the available home compared to the weighted average LTV of the portfolio of 43.12% (based on the indexed land value) reported by BNS as at April 28, 2022.

(2) BNS may need to add mortgages to maintain the Indoor swimming pool, leading to substitution risks and potential credit deterioration. These risks are mitigated by the continuous monitoring of Indoor swimming pool to ensure that the available overcollateralization is commensurate with the ratings of the Covered Bonds. According to the latest review of the Indoor swimming poolDBRS Morningstar considers an OC of 3.0%, corresponding to the minimum regulatory OC, to be proportional to the AAA odds.

(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 overcollateralisation, the constitution of a reserve fund if the SNB is not rated at least A (low) or R-1 (low) and the extension of the maturity by 12 months in the event of default of the SNB.

BNS is one of from Canada largest banks measured by assets at April 30, 2022with assets of $1,288.5 billion and the total equity of $72.0 billion. It is the initial mortgage manager in the Indoor swimming pool.
