Paragon Bank covered bond AAA

Highlights

Fitch assigns 'AAA' rating with Stable Outlook to Paragon Bank PLC's new GBP500 million Series 2026-1 floating-rate covered bond, bringing outstanding covered bonds to GBP1 billion.
Cover pool totals GBP1.53 billion as of 30 June 2026, with 95.5% interest-only loans, 71.9% self-employed borrowers, and weighted average indexed current loan-to-value at 61.2%.
Paragon's 'AAA' rating case credit loss rises to 3.9% from 3.6% after a GBP692 million top-up of less seasoned loans, increasing sensitivity to issuer downgrade or reduced collateral protection.

Rating decision and programme structure

As reported by Fitch Ratings, the agency assigns a 'AAA' rating to Paragon Bank PLC's Series 2026-1 floating-rate legislative mortgage covered bond and affirms the outstanding covered bonds at 'AAA', with Stable Outlooks.

The new issuance is a GBP500 million floating-rate covered bond due 2029 with a 12-month soft-bullet amortisation profile. After the deal, the total amount outstanding under Paragon's mortgage covered bond programme reaches GBP1 billion.

Fitch says the rating is based on Paragon's Long-Term Issuer Default Rating of 'BBB+', the uplifts applied above that rating and over-collateralisation protection provided through the programme's asset percentage. The agency says the soft-bullet covered bonds are rated seven notches above Paragon's IDR, out of a maximum achievable uplift of eight notches.

Fitch relies on an asset percentage commitment of 84.5%, which it says provides more protection than its 'AAA' break-even asset percentage of 96.0%. The agency also says the programme benefits from a six-notch payment continuity uplift and a two-notch recovery uplift, while the resolution uplift remains at zero notches.

Cover pool risks and implications for the UK market

The cover pool totals GBP1.53 billion as of 30 June 2026 and consists entirely of buy-to-let residential mortgage loans secured on properties in England and Wales. Fitch says the assets are mainly originated by Paragon and Paragon Mortgages (2010) Limited, with a weighted average seasoning of 6.8 years.

The agency highlights several non-standard characteristics in the pool, including a 95.5% share of interest-only loans, a 71.9% share of self-employed borrowers and no first-time buyers. It also notes a large concentration in houses in multiple occupation, which make up 62.9% of the current balance, alongside 6.9% in multi-unit blocks.

Fitch says the 'AAA' rating case credit loss rises to 3.9% from 3.6% after a GBP692 million top-up of less seasoned loans, pushing the weighted average indexed current loan-to-value ratio to 61.2% at end-June 2026. Asset and liability mismatch losses stand at 1.6% at the 'AA' timely payment rating level, reflecting maturity mismatches between covered bonds with a 2.4-year weighted average life and assets with a 15-year weighted average life.

For the UK covered bond sector, the rating action underlines investor support for specialist mortgage-backed funding structures, but it also shows the sensitivity of such programmes to issuer credit strength and collateral protection levels. Fitch says Paragon's 'AAA' covered bonds would be vulnerable to downgrade if the bank's IDR falls by two notches to 'BBB-' or below, or if the relied-upon asset percentage offers less protection than the agency's updated 'AAA' break-even level.

Our earlier article on Andrew Bailey’s call for targeted UK banking rule changes outlined why the Bank of England is resisting broad deregulation in a softer economic environment. We noted that recent tweaks, including easing parts of leverage-related capital requirements, aim to balance depositor protection with banks’ capacity to lend and support growth, while Bailey also stressed the need for stronger international coordination on emerging financial stability risks such as advanced AI.
