Do Depositors Benefit from Bank Mergers? An Examination of the UK Deposit Market

Research output: Contribution to journalArticlepeer-review


This study examines whether depositors benefit from bank mergers Specifically, do horizontal retail bank mergers influence the availability and interest rates of deposit services? This examination is important, as the effect of mergers on customers is a primary merger assessment criterion in the European Union and the United States. The research question is addressed by considering 57 UK banking mergers over the period 1989-2008. It is reported that different deposit services and deposits of different values face statistically insignificant levels of interest-rate change after mergers. The availability of notice deposit services for low and high levels of investment are reduced after mergers and are largely unchanged for other deposit services. It is concluded that UK depositors benefit little from bank mergers, and different types of depositor face differences in the availability of deposit services after mergers.
