Global banking, global crises? The role of the bank balance-sheet channel for the transmission of financial crises

We examine whether shocks to leveraged creditors with cross border holdings have an incidence on debtor countries' risk of suffering financial turmoil. We construct a new proxy of shocks to international banks' balance-sheets using credit ratings and the structure of their international assets. This allows us investigating the effect of (foreign) bank balance-sheet shocks on domestic financial turmoil in a large sample of 146 developed and emerging economies from 1984 to 2011. Our proxies of shocks towards bank balance-sheets are strong predictors of systemic banking crises in their debtor countries. Confirming these results, bilateral bank flows significantly decrease when creditor banks' assets are hit by negative shocks, as measured by credit rating downgrades from third-party countries. Short-term liabilities towards global banks appear to increase roll-over and funding risks, thereby amplifying the impact of shocks to foreign lenders' balance-sheets. Domestic banking sectors vulnerabilities, such as illiquid assets and a low deposit-asset ratio, are found to increase crisis contagion risk. In contrast, a high level of global liquidity attenuates the transmission of shocks to international banks' assets to debtor countries. (C) 2015 Elsevier B.V. All rights reserved.
