Asian share markets faced a testing time on Monday after Wall Street suffered its worst starting week in history and doubts over Beijing's policy choices sent investors into the arms of the safe-haven yen and sovereign bonds. The absence of Tokyo for a holiday only made liquidity even harder to come by, heightening the risk of volatility. Indeed, currency markets were already seeing wild swings with the South African rand ZAR=D3 collapsing over 10 percent at one stage.

Commodities also remained under fire as Brent crude oil LCOc1 dropped another 50 cents to $33.05 a barrel. U.S. crude CLc1 was off 59 cents at $32.57.
While many Asian markets did get a modest bounce on Friday, they still suffered their biggest weekly fall in more than four months.

S&P 500 earnings are forecast to have dropped 4.2 percent, the second-straight quarterly decline led by hard hit energy and materials companies.
The pain in stocks and unease over China even outweighed the positive impact of December's super-strong U.S. payrolls report and burnished the appeal of higher-rated government bonds.
Yields on 10-, 7-, and 3-year U.S. Treasuries all set to their biggest weekly declines since early October last year, while five-year yields dropped by the most since Sept. 2013.

The dollar fell half a yen to a near five-five month low of 116.70 yen JPY= in early trade, before steadying around 117.03.
