Cross-Border Bank Flows and Systemic Risk

Abstract

We find that heightened cross-border bank flows are associated with lower systemic risk in a target country’s banking system. The reductions in systemic risk are stronger for flows coming from source countries with stronger regulatory oversight than the target country. Such cross-border bank flows linked to regulatory arbitrage are also associated with improvements in target banking sector profitability, asset quality, and efficiency. We assess several alternative channels of influence for cross-border bank flows but interpret the evidence on these flows as mostly consistent with a benign form of regulatory arbitrage.
