We present a semi-structural model of default risk, which is a function of loan and borrower characteristics, economic conditions, and the regulatory environment. We use this model to simulate bank credit losses for stress-testing purposes and to calibrate borrower-based macroprudential tools....

The level of a bank‘s capitalization can effectively transmit information about its riskiness and therefore support market discipline, but asymmetry information may induce exaggerated or distortionary behavior: banks may vie with one another to signal confidence in their prospects by keeping...

Banks increasingly use short-term wholesale funds to supplement traditional retail deposits. Existing literature mainly points to the ""bright side"" of wholesale funding: sophisticated financiers can monitor banks, disciplining bad but refinancing good ones. This paper models a ""dark side"" of...

This paper develops a model of the lender of last resort. It provides an analytical basis for “too big too fail” and a rationale for “constructive ambiguity”. Key results are that if contagion (moral hazard) is the main concern, the Central Bank (CB) will have an excessive (little)...

The paper looks at the relationship between reserve requirements and the choice of the maturity structure of external debt in a general equilibrium setup, by incorporating the role of international lenders. A date- and maturity-specific reserve requirement is a fraction of the debt to be...

This paper develops a model where large financial intermediaries subject to systemic runs internalize the effect of their leverage on aggregate risk, returns and asset prices. Near the steady-state, they restrict leverage to avoid the risk of a run which gives rise to an accelerator effect. For...

A theoretical framework to assess the degree of fragility or, inversely, the soundness of the banking system is proposed. It is argued that, while a bank may be either solvent or insolvent at any given time, its degree of fragility must be a forward-looking measure based on the probability that...

The banking crises of the 1990s emphasize the need to model the connections between volatility and the potential losses faced by financial institutions due to correlated market and credit risks. We present a simulation model that explicitly links changes in the financial environment and the...

This paper studies episodes in which aggregate bank credit contracts alongside expanding economic activity-credit reversals. Using data for 179 countries during 1960-2017, the paper finds that reversals are a relatively common phenomenon--on average, they occur every five years. By comparison,...
