Asian shares fell for a third day in a row on Wednesday as investors grew more risk averse, with renewed uncertainty over Greece's bailout and mounting worries about slowing global economies overshadowing support from ample liquidity.
The three U.S. equity indexes recorded their biggest one-day percentage drop this year on Tuesday, while the CBOE Volatility index VIX rose, reflecting a receding appetite for riskier assets.
Commodity currencies eased, with the Australian dollar falling for a second session in Asia to a six-week low. Data showing its economy grew a disappointingly slow 0.4% last quarter also dented sentiment.
The euro benefited from players taking profits on currencies which have been rallying so far this year, notably the Aussie. The single currency, still facing huge short positions, inched up 0.2% to $1.3140, off Tuesday's three-week low of $1.3103. The Australian dollar trimmed early losses to hover around $1.054.
The MSCI Asia Pacific ex-Japan index fell 0.9%, led by the materials sector and Australian shares, which hit seven-week lows on concerns that slowing global economies would undermine demand for commodities.
The ex-Japan index had risen more than 11% so far this year through Tuesday's close, and traders said it had looked increasingly ripe for a pullback.
Japan's Nikkei average was down 0.9% after falling more than 1% to a two-week low.
Financial spreadbetters expected major European markets to open flat to 0.2% lower.
Copper remained sluggish, while oil recovered after falling the day before when worries about supply disruptions eased.
HEAT ON GREECE
Athens turned up the heat on its creditors on Tuesday as it sought to secure a bond swap that will cut its mountainous debt, while the main bondholders group warned a disorderly default would cause over a trillion euros of damage to the euro zone.
Some Greek pension funds and foreign investors rejected the offer, which will see investors lose almost three-quarters of the value of their holdings.
Greek private creditors have until Thursday night to say whether they will participate in the bond swap that is a crucial part of a bailout programme to save Greece from bankruptcy and meet a debt repayment on March 20.
More signs emerged of the damage to growth inflicted by the euro zone debt crisis, as Brazil followed China in raising fears of a slowing economy.
Data on Tuesday showed South America's largest economy expanded just 2.7% in 2011 after surging 7.5% in 2010. Quarterly growth in Oct-Dec was a scant 0.3% following a revised 0.1% contraction in the previous quarter.
China's Minister of Commerce on Wednesday said Chinese exports increased by an estimated 7% in the first two months of this year from year ago levels, while import growth was likely above 7% in the same period.
China also said it will boost energy imports in 2012, supporting oil prices which remained underpinned by supply risks and Iran's nuclear programme. Brent crude climbed above $122 and U.S. crude topped $105 a barrel.
