This paper contributes to the literature on liquidity crises and central banks acting as lenders of last resort by capturing the mechanics of dual liquidity crises, i.e. funding crises which encompass both the private and the public sector, within a closed system of financial accounts. We...

After the Lehman default, but also during the euro area sovereign debt crisis, central banks have tended to extend the ability of banks to take recourse to central bank credit operations through changes of the collateral framework (e.g. CGFS, 2008 – in consistence with previous narratives,...

This paper analyses the potential roles of bank asset fire sales and recourse to central bank credit to ensure banks' funding liquidity and solvency. Both asset liquidity and central bank haircuts are modelled as power functions within the unit interval. Funding stability is captured as...
