This paper deals with stress tests for credit risk and shows how exploiting the discretion when setting up and implementing a model can drive the results of a quantitative stress test for default probabilities. For this purpose, we employ several variations of a CreditPortfolioView-style model...

The subprime crisis revealed that the adoption of suitable systems for the management of credit risk is of utmost concern. The Basel Committee on Banking Supervision (2009) advises banks to use credit portfolio models with caution when assessing the capital adequacy. This paper investigates...

The novel partial-use philosophy by the Basel Committee on Banking Supervision initiates a paradigm shift for banks, allowing them to permanently partially apply the internal ratings-based approach (IRBA) and not having to fully roll it out across the overall bank anymore. This raises the...

In this paper, we analyze the growth effects of historical and biological ancestry, diversity and financial development in transition economies. We show that the common indicators of ethnolinguistic fractionalization, state history and genetic distance yield significant results and to some...

A large body of literature finds that managerial overconfidence increases risk-taking by financial institutions. This paper shows that financial regulation can be effective at mitigating this type of risk. Exploiting regulatory changes introduced after the financial crisis as a natural...

The paper investigates the optimal design of bank bailouts. Under three types of ex post moral hazard that tempt banks to hide loan losses, the paper analyzes banking regulation via three Prompt Corrective Action instruments: prohibition of dividends, limits on compensation to managers and early...

We study how a Net Stable Funding Ratio as defined by the Basel Committee in 2014 (NSFR (2014)) would affect the profitability of German banks and their capacity to lend. With a NSFR-model that is partially calibrated against reported NSFRs, we find that 9% of German banks do not comply with the...

Have bank regulatory policies and unconventional monetary policies - and any possible interactions - been a factor behind the recent "deglobalisation" in cross-border bank lending? To test this hypothesis, we use bank-level data from the United Kingdom - a country at the heart of the global...

How does asset encumbrance affect the fragility of intermediaries subject to rollover risk? We offer a model in which a bank issues covered bonds backed by a pool of assets that is bankruptcy remote and replenished following losses. Encumbering assets allows a bank to raise cheap secured debt...

We develop an operational model of information contagion and show how it may be integrated into a mainstream, top-down, stress-testing framework to quantify systemic risk. The key transmission mechanism is a two-way interaction between the beliefs of secondary market investors and the...
