TOKYO, Feb 25 (Reuters) - Japanese stocks climbed more than 2 percent on Monday, with Millea Holdings <8766.T> and other insurers powering higher after talk of a U.S. bond insurer rescue plan eased concerns about the subprime loan crisis.
Another boost came from a report in Britain's Times newspaper that China's sovereign wealth fund planned to buy as much as $10 billion in Japanese stocks and could consider purchasing a large stake in oil and gas developer Inpex Holdings Inc <1605.T>, which also climbed. [
]U.S. stocks staged a late rally on Friday on news that banks were near a deal to bail out bond insurer Ambac Financial, and that a rescue could come this week, though a source told Reuters that while progress has been made the deal might still fall through.
Still, investors seized on the news in Tokyo.
"One, it's the bond insurer rescue. Two, it's the bond insurer rescue," said Katsuhiko Kodama, a senior strategist at Toyo Securities Co Ltd.
"The China sovereign fund news is interesting but this is mainly a buying factor for specific stocks, not something that will necessarily lift the whole market."
But he and others remained wary even while cheering the rise.
"Of course there's questions about how much you can trust this sort of news and it's not a full solution to the subprime problems," said Noritsugu Hirakawa, a strategist at Okasan Securities.
"Still, the mood of things has changed."
Market participants said that while stocks had touched bottom and the level was gradually rising, it was hard to see sustained gains keeping the Nikkei average above 13,800 -- which was a selling point during a rally earlier this month -- for a while.
The benchmark Nikkei <
> was up 2.1 percent at 13,780.35 by midsession after earlier rising as high as 13,850.16. The broader TOPIX index < > was up 1.9 percent at 1,346.56, after earlier also rising more than 2 percent.INSURERS ENGROSSING
Insurers surged on the Ambac rescue talk, with Mitsui Sumitomo Insurance Co Ltd <8752.T> climbing 10.6 percent to 1,111 yen, Sompo Japan Insurance <8755.T> jumping 9.7 percent to 981 yen and Millea Holdings up 8.1 percent at 4,000 yen.
Aioi Insurance Co <8761.T> surged 16.7 percent to 524 yen even after saying it now expected to fall into the red this year with losses on subprime-related investments expected to balloon to about $857 million. [
]As a result, insurance <.IINSU.T> was the greatest gainer among the subindices, rising 7.9 percent. The banking subindex <.IBNKS.T> rose 3.2 percent, also on positive sentiment over a possible Ambac rescue.
Sharp Corp <6753.T> jumped 4.2 percent to 2,080 yen after a source close to the issue said Sony Corp <6758.T> was planning to start buying TV-use liquid crystal display panels from Sharp, perhaps as early as the business year starting in April -- news that market participants said contributed to the overall good mood.
Sony currently runs an LCD panel joint venture with Samsung Electronics Co Ltd <005930.KS>, but procurement from Sharp would help it secure panels to meet fast-growing demand for LCD TVs without heavy capital investment.
Sony was up 1.6 percent to 5,100 yen.
Trade picked up on the Tokyo exchange's first section, with 1 billion shares changing hands compared with last week's morning average of 961 million shares.
