This paper assesses the current state of knowledge about crisis risk and its implications for risk management. Better data that became available since the Global Financial Crisis (GFC) has improved our understanding of crisis risk. These data have been used to show that some types of crises...

Liquidity risk in banking has been attributed to transactions deposits and their potential to spark runs or panics. We show instead that transactions deposits help banks hedge liquidity risk from unused loan commitments. Bank stock-return volatility increases with unused commitments, but the...

Over the last twenty years, the consensus view of systemic risk in the financial system that emerged in response to the banking crises of the 1930s and before has lost much of its relevance. This view held that the main systemic problem is runs on solvent banks leading to bank panics. But...

We revisit the debate on the benefits of financial integration in a two-country neoclassical growth model with aggregate uncertainty. Our framework accounts simultaneously for gains from a more efficient capital allocation and gains from risk sharing-together with their interaction. In our...

This paper analyzes the influence of market discipline on the risk-taking incentives of banks. It is shown that market discipline reduces risk if banks can credibly commit to a given level of risk before the interest rate on deposits is set. If, however, the bank can readjust the level of risk...

We examine the quantification of operational risk for banks. We adopt a financial-economics approach and interpret operational risk management as a means of optimizing the profitability of an institution along its value chain. We start by defining operational risk and then propose a...

In this paper, we characterize explicitly the first derivative of the Value at Risk and the Expected Shortfall with respect to portfolio allocation when netting between positions exists. As a particular case, we examine a simple Gaussian example in order to illustrate the impact of netting...

Like many financial contracts, derivatives are subject to default risk. A very popular mechanism in derivatives markets to mitigate the risk of non-performance on contracts is margining. By attaching collateral to a contract, margining supposedly reduces default risk. The broader impacts of the...

Economic cycles are the key credit portfolio risk driver and they are autocorrelated over time. We then show that it is economically meaningful to define risk for credit portfolios in a multi period setup. Since one period expected shortfall fails to measure risk adequately in a multi period...

We introduce an adaptive importance sampling method for the loss distribution of credit portfolios based on the Robbins-Monro stochastic approximation procedure. After presenting the subtle construction of the algorithm, we apply our adaptive scheme for calculating the risk figures of a typical...
