Based on a detailed trade-level dataset, we analyze the proprietary trading behavior of German banks in the months directly preceding and following the Lehman collapse in September 2008. The default of Lehman Brothers was a shock to the German banking system that was both unexpected and...

This paper introduces a new transmission channel of banking crises where sizable cross-border bank claims on foreign countries with high domestic crisis risk enable contagion to the home economy. This asset-side channel opposes traditional views that see banking crises originating from either...

In this paper we introduce two measures, the Systemic Liquidity Buffer (SLB) and the Systemic Liquidity Shortfall (SLS) to assess liquidity in the banking system. The SLB takes an aggregated perspective on liquidity risks in the banking system. In contrast, the SLS focusses on the problematic...

In this paper, we consider models of price-mediated contagion in a banking networkof common asset holdings. For these models, the literature proposed two alternativeclasses of liquidation dynamics:threshold dynamics(banks liquidate their invest-ment portfolios only after they have defaulted),...

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...

We propose an algorithm to model contagion in the interbank market via what we term the credit quality channel. In existing models on contagion via interbank credit, external shocks to banks often spread to other banks only in case of a default. In contrast, shocks are transmitted via asset...

In Europe, the financial stability mandate generally rests at the national level. But there is an important exception. Since the establishment of the Banking Union in 2014, the European Central Bank (ECB) can impose stricter regulations than the national regulator. The precondition is that the...

We analyze the impact of financial crises and monetary policy on the supply of wholesale funding liquidity, and also on the compositional supply effects through cross-border and relationship lending. For empirical identification, we draw on the proprietary bank-to-bank European interbank dataset...

Over the past two decades, Germany experienced several periods of banking system instability rather than full-blown banking system crises. In this paper we introduce a continuous and forward-looking stability indicator for the banking system based on information on all financial institutions in...

Investment funds are highly connected with each other, but also with the broader financial system. In this paper, we quantify potential vulnerabilities arising from funds' connectedness. While previous work exclusively focused on indirect connections (overlapping asset portfolios) between...
