Wholesale Funding, Coordination, and Credit Risk

We use the global games approach to study key factors a?ecting the credit risk associated with roll-over of bank debt. When creditors are heterogenous, these include the extent of short-term borrowing and capital market liquidity for repo nancing. Specifcally, in a model with a large institutional creditor and a continuum of small creditors independently making their roll-over decisions based on private information, we ?nd that increasing the proportion of short-term debt and/or decreasing market liquidity reduces the willingness of creditors to roll over. This raises credit risk in equilibrium. The presence of a large creditor does not always reduce credit risk, however, unless it is better informed.
