This article highlights the relationships between credit bureaus and foreign bank entry. The information sharing function of credit bureaus helps banks gain access to borrowers' credit records. We collect detailed data of foreign bank offices in 80 countries and use a gravity model to test the relationship between credit bureaus and foreign expansion. Empirical results show that the existence of credit bureaus is positively correlated with foreign bank offices, i.e. foreign banks set up more offices in countries with credit bureaus. It implies that the information sharing of borrowers’ credit records encourages foreign banks to invest more in host countries.
