TOKYO/SINGAPORE (Reuters) - Asian shares caught a tailwind on Wednesday after upbeat German economic data powered gains in U.S. and European markets, while the safe-haven yen skidded as investors' mood turned positive.
MSCI's broadest index of Asia-Pacific shares outside Japan was up 2.5 percent by 0250 GMT, with gains across all the major indices that were open.
Japan's Nikkei soared 5.7 percent, on track for its biggest one-day rise since March 2011. In the previous session, it lost 2.4 percent and wiped out its year-to-date gain.
Major Wall Street indices all logged gains of more than 2 percent overnight.
European stocks also had a banner day on news Germany's imports and exports hit record highs in value terms in July.
Chinese shares rose late on Tuesday after digesting a bigger-than-expected drop in imports. The trade data raised fears that China's slowdown could be sharper than many had expected, which in turn raised hopes that Beijing would muster more easing steps to prevent a hard landing.
The Shanghai Composite index climbed 1.7 percent on Wednesday. Hong Kong's Hang Seng index added 2.7 percent.
"With many markets having been sold off heavily over recent weeks, today's rally, like the U.S. last night, represents a speculative bounce," said Angus Gluskie, managing director of White Funds Management in Sydney.
"The market will remain susceptible to a return of negativity until we see signs of some improvement in the original causes of weakness, which were predominantly Chinese growth concerns," he said.
The dollar put in a mixed performance, slipping slightly against a basket of six rival currencies to 95.945, and against the euro to $1.1191.
But the greenback firmed about 0.5 percent against the yen to 120.25 as the improved market mood sapped some of the appeal of the perceived safe-haven Japanese currency.
The euro also gained on the yen, rising 0.3 percent to 134.56.
Crude oil futures remained steady but at low levels on lingering concerns about a global supply glut.
U.S. crude rose 0.2 percent to $46.15 ahead of weekly crude inventories data due from industry group American Petroleum Institute later in the session.
Brent crude rose 0.4 percent to $49.74, after jumping 4 percent the previous session following upbeat German economic data.
