Abstract

Interbank markets have been at the core of the international transmission of recent financial crises, including the European sovereign debt crisis. We study the transmission of shocks in a two-country DSGE model where banks pledge government bonds as collateral in interbank markets. A standard “bank net worth channel” amplifies negative shocks to the returns of private loans. However, an “interbank collateral channel” can partially contrast the bank net worth channel. The stabilizing interbank collateral channel works through banks' portfolio switch towards government bonds, which helps sustain the value of banks' bond holdings and partially relax collateral constraints in the interbank market. Unconventional credit policies raise banks' liquidity but, if financed through government debt issuance, can undermine the stabilizing effect of the interbank collateral channel. The analysis yields insights for the optimal design of credit policies during sovereign debt crises.
