We study the transmission of financial shocks across borders through international bank connections. Using data on cross-border interbank loans among 6,000 banks during 1997-2012, we estimate the effect of asset-side exposures to banks in countries experiencing systemic banking crises on profitability, credit, and the performance of borrower firms. Crisis exposures reduce bank returns and tighten credit conditions for borrowers, constraining investment and growth. The effects are larger for foreign borrowers, including in countries not experiencing banking crises. Our results document the extent of cross-border crisis transmission, but also highlight the resilience of financial networks to idiosyncratic shocks.
