Credit risk models used in quantitative risk management treat credit risk analysis conceptually like a single person decision problem. From this perspective an exogenous source of risk drives the fundamental parameters of credit risk: probability of default, exposure at default and the recovery...

We evaluate the abnormal returns of issuing and non-issuing banks around the announcement of Seasoned Equity Offerings (SEOs) and explore how the market reaction is influenced by aggregate systemic conditions and by the systemic risk contribution and exposure of banks. While we find evidence of...

We analyze the impact of capital adequacy regulation on bank insolvency and aggregate investment. We develop a model of the banking system that is characterized by the interaction of many heterogeneous banks with the real sector, interbank credit relations as a consequence of bank liquidity...

Since the nineties, crises have punctuated financial markets, shattering the conventional wisdom about how these markets work and how to regulate them, and forcing a deep rethinking of the supervisory framework that, however, did not change much of the banks' behavior and incentives. In...

The global financial crisis shattered the conventional wisdom about how financial markets work and how to regulate them. Authorities intervened to stop the panic-short-term pragmatism that spoke volumes about the robustness of mainstream economics. However, their very success in taming the...

We give a precise operational definition to three requirements the Basel Committee on Banking Supervision specifies for stress tests: Plausibility and severity of stress scenarios as well as suggestiveness of risk reducing actions. The basic idea of our approach is to define a suitable region of...

Debt overhang and moral hazard related to risk-shifting opportunities predict that low capitalized banks have a lower likelihood to issue equity. In contrast to this view, for an international sample of bank Seasoned Equity Offerings (SEOs), we show that the likelihood of issuing an SEO is...

This paper analyzes the contagion effects associated with the failure of Silicon Valley Bank (SVB) and identifies bank-specific vulnerabilities contributing to the subsequent declines in banks' stock returns. We find that uninsured deposits, unrealized losses in held-to-maturity securities, bank...

For a given set of banks, which economic and financial scenarios will lead to big losses? How big can losses in such scenarios possibly get? These are the two central questions of macro stress tests. We believe that most current macro stress testing models have deficits in answering these...

We present a simple and operational yet rigorous framework that combines current methods of bank solvency stress tests with a description of fire sales. We demonstrate the applicability of our framework to the EBA stress testing exercise. Fire sales are described by an equilibrium model which...
