Market players now expect the US Federal Reserve to defer the planned reduction of its $85 billion-a-month bond-buying stimulus, to early 2014.
"For the Fed, the key takeaway from the report is likely to be that the [US] economy is in no shape to deal with the level of reduction in monetary policy stimulus," said Millan Mulraine at TD Securities in New York.
"Given the uncertainty about . . . the fallout from the government shutdown on the economy it will probably be some time before a clear picture emerges," Mulraine added, reported the Financial Times.
In China, market players blamed the heavy selling on reports that leading Chinese lenders, including Industrial and Commercial Bank of China (ICBC), had erased $3.7 billion worth of bad debt in the first half of 2013, higher than the preceding year's figure.
However, banking stocks were unaffected by the news.
"A lot of this write-off brings Chinese banks closer to a more international standard. In the past, they've put these loans further out into their non-performing portfolios rather than instead of actually writing them off so in some respects, this improves the health of these banks," said Andrew Sullivan, director of Asian Sales Trading.
