第一勧業銀行
The TKB-Mitsui merger, agreed in 1989 during the height of the Japanese asset price bubble, was to create the second largest bank in the world behind Dai-Ichi Kangyo Bank. While TKB had a large base of individual and small business customers, Mitsui had a complementary base of larger institutional clients. The merger was aimed at leveraging these synergies, as well as providing stronger competition against European banks, which were expected to consolidate following a deregulation in 1992.
