TOKYO, March 24 (Reuters) - Japan's Nikkei average briefly climbed nearly 3 percent to a more than two-month high on Tuesday, buoyed by bank shares such as MUFG <8306.T> as a U.S. plan to rid the banking sector of bad assets sparked hopes for stability in the financial system.
Among strong individual gainers, Nippon Steel Corp <5401.T> climbed 3.4 percent to 278 yen after a company official said the firm had sealed a year-on-year discount of about 57 percent on coking coal contracts with BHP Billiton Mitsubishi Alliance for fiscal 2009/10. [
]U.S. stocks leapt about 7 percent on Monday after Washington gave details of its plan to purge toxic assets from bank balance sheets, fuelling optimism about a revival in bank lending and driving double-digit gains in financial shares. [
]"The key point of the U.S. plan is that money may start flowing again, helped by a push by the government. That sparked hopes that the financial system will stabilise," said Masaru Hamasaki, senior strategist at Toyota Asset Management.
"But unless we see signs of the recovery in the economy and then corporate earnings, the Nikkei will find it hard to go above the 9,000 mark."
