Foreign Entry into Underwriting Services: Evidence from Japan's “Big Bang” Deregulation

We examined the effect of foreign entry into bond market underwriting activity using issue‐level data from the Japanese “Samurai” and euro–yen bond markets. We found that the fees charged by Japanese underwriters were higher on average than those of foreign underwriters, but the difference could be explained by conditioning on issue characteristics. Our results also suggest that bond issuers sorted properly across underwriters, as switching across underwriter nationalities would be expected to result in higher fees. However, the savings enjoyed by firms issuing with foreign underwriters were modest and statistically insignificant, while those of firms issuing with Japanese underwriters were substantial and statistically significant. This result suggests that Japanese underwriters priced their services aggressively over the sample period, perhaps in an effort to retain or gain market share. This conjecture is supported by a matching exercise that examined the liberalization of foreign underwriter access to the Samurai bond market, using euro–yen bond issues as a control. Foreign entry led to a statistically and economically significant decrease of 16 basis points on average in underwriting fees in the Samurai bond market. Overall, our results suggest that the international market for Japanese bond underwriting services was partially segmented by nationality as issuers appear to have preferred habitats, but that liberalization increased overall market competition.
