Japan’s Mizuho Financial forecasts annual net loss

TOKYO — Mizuho Financial Group Inc., Japan’s second-biggest bank, warned Thursday that it sank into the red last fiscal year amid mounting bad loans and steep stock market declines.

The Tokyo-based lender slashed its earnings guidance for the 12 months through March 31, saying it expects a group net loss of 580 billion yen ($5.9 billion) — its first annual loss in six years.

The company had been projecting a 100 billion profit. It made 311 billion yen in profit the previous year.

Mizuho said pretax losses will be around 400 billion yen, compared with the forecast for a 220 billion yen pretax profit that it announced in January.

The company blamed higher credit-related costs stemming from the global financial crisis and “significant declines in both domestic and overseas stock prices and the sharp economic downturn.”

Japan’s three “megabanks” — Mizuho, Mitsubishi UFJ Financial Group Inc. and Sumitomo Mitsui Financial Group Inc. — are now all expected to post annual losses. Mizuho’s earnings are due on May 15.

Earlier this month, Sumitomo Mitsui Finanical Group rattled investors when it unexpectedly downgraded its earnings guidance. It expects to post a group net loss of 390 billion yen ($4 billion).

Major Japanese banks managed to weather the U.S. subprime mortgage crisis with far smaller losses than their Western counterparts, but they are now facing the painful impact of Japan’s recession.

Cross-shareholding arrangements with domestic companies, commonly used to foster business ties, are proving toxic amid deep equity falls. Bad loans are also mounting as more companies face bankruptcy.

Investors anticipating Thursday’s announcement turned bearish on Mizuho, which fell 1 percent to 192 yen compared to the benchmark Nikkei 225 index’s 1.4 percent rise.
