Resona is the fifth-largest banking group in Japan. Recently the Resona Group's capital adequacy ratio(資本充足率) had fallen dangerously low. The Resona case would have an impact on other main banks, which are also factoring in large amounts of deferred tax assets. On May 17 2003, the Japan government decided to inject public funds(公的資金) into the Resona Group. The move is designed to help the struggling bank, and shows the diminishing economy of Japan.
