Ameliorating these incentive problems should be a central component of any post-crisis strategy to better manage credit risk and set future financial sector growth on a stable footing. This paper examines the case for a statutory covered bonds mortgage funding framework as a possible approach to achieving this objective. Part of the appeal of covered bonds derives from their basic financial structure. They combine the scale advantages of capital market funding with on-balance sheet credit risk management by the lender. Incentives for maintaining high quality of collateral, capacity, and credit assessment are, therefore, stronger than under the incumbent model.
