This paper provides evidence of a highly fragmented European interbank market that is tightened during the COVID-19 pandemic, when the interbank market was under stress. Using a unique dataset of unsecured, overnight interbank loans at the transactional level allows me to apply advanced panel...

We use a unique security-level data set to analyze correlations in bond trading of banks, their respective retail customers and their affiliated mutual funds. Matching banks' proprietary holdings with the holdings of their funds and their retail customers for the period 2009-2016 at the security...

What is the impact of a sudden and sizeable increase in bank capital requirements on the lending activity by directly affected banks and by non-affected non-bank financial institutions (NBFIs)? To answer this question, we apply a difference-in-differences methodology around the capital exercise...
