The Citicorp-Travelers Group merger increased the prospects for new legisla
tion to remove the barriers between banking and insurance, resulting in a p
ositive wealth effect for institutions most likely to gain from deregulatio
n. Analysis of abnormal returns surrounding the merger show that life insur
ance companies and large banks (excluding Citicorp and Travelers Group) hav
e significant stock price increases, while the returns of small banks, heal
th insurers, and property/casualty insurers are insignificantly different f
rom 0. This analysis provides evidence that investors expect large banks an
d insurance companies to receive significant benefits from recent congressi
onal legislation removing barriers to bancassurance. (C) 2001 Elsevier Scie
