TOKYO, March 7 (Reuters) - Japan's Nikkei average fell 2.9 percent to a six-week low on Friday as investors sold exporters such as Sony Corp <6758.T> on a stronger yen and fears of a U.S. recession, while silicon wafer maker Sumco Corp <3436.T> tumbled after predicting weaker profits.
Banks such as Mitsubishi UFJ Financial Group <8306.T> also took a beating after U.S. mortgage lender Thornburg Mortgage Inc <TMA.N> said it failed to meet a $28 million margin call, the latest victim of the global credit crisis. [
].Investors shifted funds into the perceived safety of Japanese government bonds, with the benchmark 10-year yield <JP10YTN=JBTC> falling as low as 1.325 percent to come in sight of a one-month low of 1.320 percent hit on Monday.
"Credit fears are spreading. Things like that probably won't be over after one or two cases and investors are worried there will be more," said Takahiko Murai, general manager of equities at Nozomi Securities.
"We now have more pessimists in the market in terms of whether the U.S. will tip into a recession or it will be just a temporary slowdown," predicting the Nikkei could fall to the 11,000-12,000 level.
The benchmark Nikkei average <
> ended the morning session down 378.60 points at 12,836.82, hitting its lowest point since Jan. 23. It fell as much as 3.6 percent at one point. The broader TOPIX index < > shed 2.6 percent to 1,254.56.Yumi Nishimura, manager of the investment advisory section at Daiwa Securities SMBC, said investors were unlikely to push the market down much further as they wait for U.S. jobs data out later in the day for further clues on the health of the economy.
"There's a possibility that investors will pick up shares if the data turn out to be in line with or better than expectations," she said.
Economists expect the government's non-farm payrolls report to show the U.S. job market probably rebounded in February from the previous month's contraction, but not enough to keep the unemployment rate from rising. [
]EXPORTERS, SUMCO SLIDE
Shares of exporters fell sharply after lacklustre U.S. retail sales data and a report showing that U.S. mortgage foreclosures hit a record high in late 2007 added to fears that the U.S. economy is near a recession, which would hurt demand for Japanese goods.
The dollar's fall to a three-year low of 102.45 yen <JPY=>. <FXNEWS> [
] gave investors another reason to sell auto and tech exporters, many of which have assumed a currency rate of 105 yen to the dollar in making their profit forecasts.A stronger yen makes Japanese goods less competitive in overseas markets and cuts into profits made abroad when brought back to Japan.
Shares of Sony slipped 4.7 percent to 4,630 yen, automaker Toyota Motor Corp <7203.T> dropped 3.3 percent to 5,330 yen and office equipment maker Konica Minolta Holdings <4902.T> tumbled 6.7 percent to 1,268 yen.
Among banks, Mitsubishi UFJ fell 3.4 percent to 869 yen, No.2 Mizuho Financial Group <8411.T> declined 4.4 percent to 396,000 yen and Sumitomo Mitsui Financial Group <8316.T>, the third-biggest bank, dropped 5.3 percent to 691,000 yen.
Shares of Sumco slid 10.8 percent to 2,065 yen after it forecast a 22 percent fall in operating profit this fiscal year, which started in February, due to a stronger yen, softening wafer prices and a heavier depreciation burden. [
