This paper tests financial contagion due to interbank linkages. For identification we exploit an idiosyncratic, sudden shock caused by a large-bank failure in conjunction with detailed data on interbank exposures. First, we find robust evidence that higher interbank exposure to the failed bank...

This paper examines common regulation as cause of interbank contagion. Studies based on the correlation of bank assets and the extent of interbank lending may underestimate the likelihood of contagion because they do not incorporate the fact that banks have a common regulator. In our model, the...

In European countries recently hit by a sovereign debt crisis, the share of domestic sovereign debt held by the national banking system has sharply increased, raising issues in their economic and financial resilience, as well as in policy design. This paper examines these issues by analyzing the...

This paper investigates the costs and benefi ts of liquidity regulation. We find that liquidity tools are bene ficial but cannot completely remove the need for Lender of Last Resort (LOLR) interventions by the central bank. Full compliance with current Liquidity Coverage Ratio (LCR) and Net...

We study the functioning and possible breakdown of the interbank market in the presence of counterparty risk. We allow banks to have private information about the risk of their assets. We show how banks' asset risk affects funding liquidity in the interbank market. Several interbank market...

Basel III has introduced a non-risk-weighted leverage ratio requirement (LRR) which complements the internal ratings based (IRB) capital requirements. It provides a backstop against model risk which arises if some loans get incorrectly rated and become toxic. We study the effects of the LRR on...

The regulatory use of banks' internal models aims at making capital requirements more accurate and reducing regulatory arbitrage, but may also give banks incentives to choose their risk models strategically. Current policy answers to this problem include the use of risk-weight floors and...

We show that a reduction in lender of last resort (LOLR) policy uncertainty positively affects bank lending and propagates to investment and employment. We exploit a unique policy that reduced uncertainty regarding the availability of future LOLR funding for banks as a quasi-natural experiment....

Negative monetary policy rates are associated with a particular friction because the remuneration of retail deposits tends to be floored at zero. We investigate whether this friction affects banks' reactions when the policy rate is lowered to negative levels, compared to a standard rate cut in...

Negative interest rate policy (NIRP) is associated with a particular friction. The remuneration of banks´ retail deposits tends to be floored at zero, which limits the transmission of policy rate cuts to bank funding costs. We investigate whether this friction affects banks’ reactions under...
