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 use of collateral has become one of the most widespread risk mitigation techniques. While it brings stabilizing effects to the individual lender we argue that it may exacerbate systemic risk through margin call activation. We show how a liquidity shock to the cash lender may propagate as a...

In this paper, we discuss whether and how bank lobbying can lead to regulatory capture and have real consequences through an overview of the motivations behind bank lobbying and of recent empirical evidence on the subject. Overall, the findings are consistent with regulatory capture, which...

We present a novel approach that incorporates individual entity stress testing and losses from systemic risk effects (SE losses) into macroprudential stress testing. SE losses are measured using a reduced-form model to value financial entity assets, conditional on macroeconomic stress 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,...

We explore empirically how the time-varying allocation of credit across firms with heterogeneous credit quality matters for financial stability outcomes. Using firm-level data for 55 countries over 1991-2016, we show that the riskiness of credit allocation, captured by Greenwood and Hanson...

Advocates for internal model-based capital regulation argue that this approach will reduce costs and remove distortions that are created by rules-based capital regulations. These claims are examined using a Merton-style model of deposit insurance. Analysis shows that internal model-based capital...

Globally, financial institutions have increased their holdings of domestic sovereign debt, tightening the linkage between the health of the financial system and the level of sovereign debt, or the "financial sector-sovereign nexus," during the ongoing COVID-19 pandemic. In South Africa, the...

This paper presents a novel approach to investigate and model the network of euro area banks' large exposures within the global banking system. Drawing on a unique dataset, the paper documents the degree of interconnectedness and systemic risk of the euro area banking system based on bilateral...
