Abstract

This paper studies the mutual interplay between central bank (CB) liquidity provisions and interbank markets (IM) liquidity exchanges exploring whether the relationship changes during IM impairments and CB massive liquidity injections in the global and sovereign crises. The analysis leverages on a dataset containing seventeen years of monthly bank-by-bank and counterparty-by-counterparty data from 1998 to 2015 in Italy. The results show the existence of a complementarity relationship. Banks receiving CB liquidity redistribute more to other banks. When CB liquidity increases exponentially in the crises some healthy banks specialize in interbank lending. The complementarity relationship helps to offset the euro-area fragmentation via domestic interbank relationships and to adjust collateral and maturity profiles of banks’ liquidity.
