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 U.S. 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 .MIAPJ0000PUS tumbled 1.6 percent to nearly a five-month low, on track for its worst one-day performance since August after losing more than 1.0 percent on Friday. Japan's Nikkei share average .N225 gave up the 15,000-level and dropped 2.7 percent.
Expectations of continued stimulus withdrawal by the U.S. 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 percent.

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 U.S. and Japanese equities, and the sharp decline in U.S. 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 U.S. yields and/or recovery in the equity markets," they added.
