The shadow cost of repos and bank liability structure


Moreno, Santiago; Klimenko, Nataliya (2015). The shadow cost of repos and bank liability structure. Swiss Finance Institute Research Paper 15-04, University of Zurich.

Abstract

Making use of a structural model that allows for optimal liquidity management, we study the role that repos play in a bank's financing structure. In our model the bank's assets consist of illiquid loans and liquid reserves and are financed by a combination of repos, long--term debt, deposits and equity. Repos are a cheap source of funding, but they are subject to an exogenous rollover risk. We show that their use adds to the cost of long--term debt financing, which limits the bank's appetite for unstable repo funding. This effect is, however, weakened under poor returns on assets, abundant deposit funding and the depositor preference rule. We also analyze the impact of a liquidity coverage ratio, payout restrictions and a leverage ratio on the bank's financing choices and show that all these tools are able to curb the bank's reliance on repos.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
