The head of Sumitomo Mitsui Financial Group Inc (SMFG), SMBC Nikko's parent, will also face a pay cut of 30% over six months, Japan's second-largest financial group said.

SMBC Nikko and six former executives have been indicted on market manipulation charges over the purchase of 10 individual stocks, allegedly to push up their prices and ensure that block trade deals in them did not fall through.

Japan's financial regulator last month ordered both SMFG and SMBC Nikko to improve compliance.
