Covered Bond

The defining mechanic is that the cover pool never leaves the issuing bank's balance sheet. Assets are ring-fenced by statute or contract rather than sold to a special purpose entity, so bondholders remain ordinary senior creditors of the bank while also holding a preferential claim over the segregated assets. If the bank remains solvent, coupons and principal are paid from general resources like any other senior unsecured obligation; the pool matters only in default.

Because the bank retains the assets, it also retains an ongoing obligation to maintain them. Loans that become delinquent, breach loan-to-value limits or amortise away must be replaced with eligible substitutes. This dynamic replenishment, combined with overcollateralisation, is what distinguishes the structure from a static pool. The coverage ratio is simply the value of eligible cover assets divided by the nominal amount of covered bonds outstanding; legislation or the programme documentation sets a minimum, and issuers typically run well above it to protect ratings.

Eligibility criteria are deliberately narrow. Typical pools admit only first-lien residential or commercial mortgages within a specified loan-to-value cap, exposures to sovereigns and other public-sector borrowers, and a limited buffer of liquid substitute assets. Concentration limits, geographic restrictions and valuation rules further constrain what may enter.

Programmes are monitored through coverage tests run at regular intervals, often supervised by an independent cover pool monitor and the banking regulator. The asset coverage test compares the adjusted value of pool assets, where amounts above the LTV cap are excluded and delinquent loans are haircut or disregarded, against outstanding bonds plus accrued interest and expected administrative costs. Failure obliges the issuer to add assets. Separate liquidity requirements demand that the pool hold enough short-dated assets to cover net outflows over a forward window, so that a bank failure does not immediately interrupt payments.

Three redemption conventions dominate. Hard bullet bonds must repay principal on the stated date. Soft bullet bonds allow an extension, commonly by twelve months, if the pool cannot be monetised in time. Conditional pass-through bonds convert to amortising cash flows sourced from the pool if the issuer defaults and the bullet cannot be met. Critically, prepayment and extension risk on the underlying mortgages sits with the bank, not the investor, because the bond's schedule is contractual rather than a pass-through of borrower behaviour.

Covered bonds are the backbone of European bank term funding, with Germany, Denmark, France, Spain and the Nordics the deepest markets, alongside established programmes in Canada, Australia and Singapore. Regulatory treatment reinforces demand: favourable risk weights, eligibility as high-quality liquid assets under liquidity rules, central bank repo eligibility and inclusion in official purchase programmes all compress spreads relative to senior unsecured debt of the same issuer.

Expect to compare a covered bond against a securitisation of the same collateral and explain the spread differential. The argument runs through expected loss: two independent sources of recovery, a pool that is actively topped up, statutory segregation, and no subordination of one class of holders to another, since all bonds of a programme rank equally on the pool. That combination supports the highest rating categories and a rating uplift above the issuer's own senior unsecured rating.

You should also be able to place the instrument correctly in a bank's funding hierarchy, from deposits through covered bonds, senior preferred and senior non-preferred debt down to subordinated capital. Finally, be ready to identify the residual risks that dual recourse does not eliminate: sovereign and regulatory risk, since protection depends on national law, concentration of the pool in one property market, refinancing risk if pool assets cannot be sold at par, and negative pledge concerns as encumbered assets reduce recoveries for unsecured creditors.
