Mizuho Financial Group Inc. raised its full-year profit forecast 20 percent as the stock market rally spurred fee income and the value of its share-holdings.

Net income will probably total ¥600 billion in the year ending March 31, the nation's third-biggest bank by market value said Thursday. That compares with the ¥500 billion previously forecast and the ¥574.9 billion average estimate of 18 analysts in a survey.

Regulators are investigating the bank and President Yasuhiro Sato has been grilled in the Diet for failing to end loans to crime groups.
