Abstract:
This study investigates the motive of geographic risk diversification in the lending activity for bank mergers in the EU on a sample of large banking groups. Geographic diversification should allow banks to reduce their risk. It is observed that the loan portfolios of European banks are home-biased. The portfolio approach is applied to explore the risk-return efficiency of the locations of banks' activities. Mergers between pairs of banks are also studied. Evidence of the sub-optimality of the loan portfolios of European banks in terms of geographic risk diversification, and of the existence of potential gains from inter-country pair mergers is also provided.
