Tokyo  - Japan's three biggest banking groups were expected to report net losses for the fiscal year that ended March 31 amid worsening global financial turmoil, media reports said Thursday.

Such losses would mark the first time in six years that all of Japan's three megabanks would swing into the red.

Mizuho Financial Group Inc was to incur a net loss of more than 500 billion yen (5 billion dollars) because of massive stock and credit losses, Jiji Press quoted sources familiar with the matter as saying.

The firm had projected a profit of about 100 billion yen in May but was scheduled to revise its earnings later in the day.

Sumitomo Mitsui Financial Group Inc announced early this month that it would incur a net loss of 390 billion yen for the past fiscal year, a turnaround from earlier profit forecasts.

Sumitomo Mitsui had expected a net profit in November but revised it into a loss amid declining stock prices and the global financial turmoil.

Mitsubishi UFJ Financial Group Inc was also expected to report a net loss after its losses expanded from declines in stock prices and increases in the costs of bad-loan write-offs, Jiji said. (dpa)
