We study solvency contagion risk in the UK banking system from 2008 to 2015. We develop a model that only accounts for losses transmitted after banks default, but also for losses due to the fact that creditors revalue their exposures when probabilities of default of their counterparties change....

In this paper, we analyse the network of exposures constructed by using the UK trade repository data for three different categories of contracts: interest rate, credit, and foreign exchange derivatives. We study how liquidity shocks related to variation margins propagate across the network and...

We investigate whether margin calls on derivative counterparties could exceed their available liquid assets and, by preventing immediate payment of the calls, spread such liquidity shortfalls through the market. Using trade repository data on derivative portfolios, we simulate variation margin...

We explore the impact of central clearing on the demand for collateral arising from variation margin calls in the derivatives market. We find that the aggregate demand for collateral is not necessarily minimal when all contracts are centrally cleared. Hence, at least in this respect, increasing...
