Asian shares took a beating and the yen raced to a seven-week high against the dollar on Monday, as emerging markets remained under pressure with the US Federal Reserve poised to continue tapering its stimulus and tighter credit conditions in China raising fears of a slowdown.
MSCI's broadest index of Asia-Pacific shares outside Japan tumbled 1.6 per cent to nearly a five-month low, on track for its worst one-day performance since August after losing more than 1.0 per cent on Friday. Japan's Nikkei share average gave up the 15,000-level and dropped 2.7 per cent.
Expectations of continued stimulus withdrawal by the US Federal Reserve added to the market's gloom.

The dollar slipped as low as 101.77 yen early on Monday, its weakest level since December 6, and was last trading at 102.22 yen, down about 0.2 per cent. The yen's session high marked a strengthening of more than 2 yen over the past three sessions, as Japanese stocks withered in line with their global counterparts.
The euro also fell to a seven-week low of 139.25 yen but recouped some losses to buy 139.85 yen.
"The combination of the drop in US and Japanese equities, and the sharp decline in US bond yields helped accelerate the short squeeze, which was already helping the yen recover," strategists at Brown Brothers Harriman said in a note to clients.
"Renewed yen weakness would seem to require a move back up in US yields and/or recovery in the equity markets," they added.
