We introduce a model of the banking sector that formally incorporates a buffer function of capital. Heterogeneous banks choose their portfolio risk, bank size, and capital holdings. Banks voluntarily hold equity when the buffer effect against the risk of default outweighs the cost advantages of...

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...

Our paper addresses firm size as a driver of systematic credit risk in loans to small and medium enterprises (SMEs). Key contributions are the use of a unique data set of SME lending by over 400 German banks and relating systematic risk to the size dependence of regulatory capital requirements....

We look at the effect of capital rules on a banking system that is connected through correlated credit exposures and interbank lending. The rules, which combine individual bank characteristics and interconnectivity measures of interbank lending, are to minimize a measure of system-wide losses....

M-PRESS-CreditRisk is a new top-down macro stress testing framework that can help supervisors gauge banks' capital adequacy related to credit risk. For the first time, it combines calibration of microprudential capital requirements and macroprudential buffers in a unified, coherent framework....

Several countries have recently introduced national capital standards exceeding the internationally coordinated Basel III rules, which is inconsistent with the 'race to the bottom' in capital standards found in the literature. We study regulatory competition when banks are heterogeneous and give...

We use a newly constructed narrative measure of regulatory bank capital requirement tightening events (Eickmeier et al., 2018) to examine their effects on household income and expenditure inequality in the US. Income and expenditure inequality both decline (the latter decline being slightly less...

We investigate how banks' capital and lending decisions respond to changes in bankspecific capital and disclosure requirements. We find that an increase in the bankspecific regulatory capital requirement results in a higher bank capital ratio, brought about via less asset risk. A decrease in the...
