Bank funding structure and lending under liquidity shocks: Evidence from Korea

Abstract

This paper examines the relation between bank funding structure and lending to firms during periods of liquidity shocks. We analyze this relation by using quarterly loan panel data of all commercial banks in Korea, as well as their borrowing firms. We find that when liquidity shocks are severe, banks generally reduce their lending, but banks with a high core funding ratio tend rather to increase their lending to firms during periods of market-wide liquidity shocks, thereby offsetting the reduction in lending due to liquidity shocks. This tendency is stronger in banks that maintain relationship banking with these firms. However, these findings are valid only for large banks. Our findings could provide some important policy implications for financial supervisory authorities seeking some regulatory policies on liquidity such as those of Basel III. (C) 2015 Elsevier B.V.
