This article analyses the dispersion of risk weights for large corporate portfolios and identifies the sources of dispersion among banks in terms of the Basel risk parameters. The analysis focuses on loans granted by 5 large French banking groups to large corporates operating in France and rated...

We study the real effect on banks’ credit supply after a negative liquidity shock. Controlling for demand effects, we take advantage of the exogenous international interbank market freeze in 2007-2008 to assess the causal relation between French banks’ liquidity risk and their lending. We...

Financial institutions’ interconnectedness is a key component of systemic risk. However there is still no consensus on its measurement. Using a unique database of network of exposures of French financial institutions, we compare three strategies to measure interconnectedness: closeness of...

This paper studies the scope for cross-border contagion in the European banking sector using true bilateral exposure data. Using a model of sequential solvency and liquidity cascades in networks, we analyze geographical patterns of loss propagation from 2008 to 2012. We study the distribution of...

We exploit the Eurosystem’s longer-term refinancing operations (LTROs) of 2011-2012 to analyze the effects that a large provision of central bank liquidity to banks has on the credit supply to firms. We control for credit demand by examining firms that borrow from several banks, in addition to...

This paper presents the main features of macroprudential policy with a focus on the French case. We first recall the ultimate objective of this policy, which is to prevent and to mitigate systemic risk, i.e. the risk of “widespread disruptions to the provision of financial services that have...

This paper examines the sensitivity of non-financial corporate lending to banks' capital ratio and their supervisory capital requirements. We use a unique database for the French banking sector between 2003 and 2011 combining confidential bank-level Bank Lending Survey answers with the...

This paper explores how different types of financial regulation could combat many of the phenomena that were observed in the financial crisis of 2007 to 2009. The primary contribution is the introduction of a model that includes both a banking system and a “shadow banking system” that each...

This paper proposes a network formation model of an OTC derivatives market where both prices and quantities are bilaterally negociated. The key feature of the framework is to endogenize the network of exposures, the gross and net notional amounts traded and the collateral delivered through...

The paper examines a continuous-time delegated monitoring problem between a competitive investor and an impatient bank monitoring a pool of long-term loans subject to Markovian "contagion." Moral hazard induces a foreclosure bias unless the bank is compensated with the right incentive-compatible...
