The brief answer is that Danmarks Nationalbank will act as the lender of last resort – as it does for other banks – if the mortgage bank is solvent and can pledge adequate collateral. In practice, the latter would presumably be all the bonds not sold in the market.
Early intervention procedures therefore need to be spelled out so that institutions in difficulties are dealt with before they infect the rest of the system. Let me conclude: the international financial system has had a close shave. With luck, and skilful management from now on, there is a good chance that things will now get better.
