Using unique supervisory survey data on the impact of a hypothetical interest rate shock on German banks, we analyse price and quantity effects on banks' net interest margin components under different balance sheet assumptions. In the first year, the cross-sectional variation of banks' simulated...

Repo markets offering central counterparty (CCP) clearing and anonymized trading were remarkably resilient during the recent crises. We use the full transaction level dataset on all repo trades on Eurex Repo, including identifiers for market participants, to provide a detailed description of the...

The reuse of collateral can support the efficient allocation of assets in the financial system. Exploiting a novel dataset, we quantify banks’ collateral reuse at the security level. We show that banks substantially increase their reuse of collateral in response to scarcity induced by central...

We use a unique data set that comprises each bank’s bids in the Eurosystem’s main refinancing operations and its recourse to the LOLR facility (a) to derive banks’ willingness-to-pay for liquidity through a one-week repo and (b) to show that a bank’s willingness-to-pay is a good...

This paper examines how the exposure of German parent banks to the disruptions on sale and repurchase markets (repo markets) during the financial crisis has affected their provision of funds to their foreign branches and subsidiaries via bank-internal capital markets. The collapse of the...

The Eurosystem's asset purchase programmes reduced the free float of German Bunds. Market participants feared impaired market functioning in the Bund market and monetary policymakers unintended consequences for monetary policy transmission. We study the intended and unintended consequences of...
