The Industrial Bank of Japan, Shinsei Bank and Aozora Bank said Tuesday that they will leave the long-term prime lending rate at 2.1 percent, as fluctuations in the coupon rate on five-year debentures remain in a narrow range.
They cut the prime lending rate in December for the third straight month.
The long-term prime rate, charged to the bank's most creditworthy customers on loans of one year or longer, is customarily set 0.9 point higher than the coupon on five-year debentures issued monthly to institutional investors.
