Regulatory Arbitrage and Cross-Border Bank Acquisitions

We study how differences in bank regulation influence cross-border bank acquisition flows and share price reactions to cross-border deal announcements. Using a sample of 7,297 domestic and 916 majority cross-border deals announced between 1995 and 2012, we find evidence of a form of "regulatory arbitrage" whereby acquisition flows involve acquirers from countries with stronger regulations than their targets. Target and aggregate abnormal returns around deal announcements are positive and larger when acquirers come from more restrictive bank regulatory environments. We interpret this evidence as more consistent with a benign form of regulatory arbitrage than a potentially destructive one.
