Unsecured and Secured Funding

We empirically investigate why wholesale funding is fragile by providing the first study of how individual banks borrow and lend in the euro unsecured and secured interbank market. Consistent with theories in which lenders enforce market discipline by monitoring counterparty credit risk and theories highlighting that secured loans are less informational sensitive, we find that banks with low credit worthiness replace unsecured borrowing with secured loans. Moreover, riskier lenders provide more secured loans to replace unsecured lending, which is not consistent with speculative or precautionary liquidity hoarding theories. Instead, lenders are precautionary in the sense that they prefer to lend against safe collateral.
