Lenders were in the firing line after the Financial Services Regulator last week carried out a health check on banks' ongoing efforts to clamp down on bad loans. It revealed that potential loanloss charges were still rising - not falling as many investors had hoped. Mizuho Financial dived 19,000 yen or 7.2% to 221,000 yen, UFJ fell 22,000 yen or 5.4% to 383,000 yen and Sumitomo Mitsui Financial traded at 470,000 yen, lower by 26,000 yen or 5.2%.
