Uncertainty drags down markets

The euro, commodities and Asian shares fell today, weighed down by uncertainty about Spain's bailout and concerns over a slowdown in demand that was underscored by sluggish business activity data in Japan and China.

Trade was subdued, with several Asian markets closed for holidays, including China, Hong Kong and South Korea.

"Investors are focusing on demand indicators being weaker than expected," said Natalie Rampono, a commodity strategist with ANZ in Melbourne.

A 0.4 per cent drop in US stock futures hinted at a weak start on Wall Street, while financial spreadbetters expect London's FTSE 100, Paris's CAC-40 and Frankfurt's DAX to open down as much as 0.3 per cent.

The MSCI index of Asia-Pacific shares outside Japan fell 0.3 per cent. The Australian market was caught in choppy trade, rising as much as 0.6 per cent before ending flat. Taiwan stocks slid 0.6 per cent after rising 5.7 per cent in the third quarter.

Japan's Nikkei stock average fell 0.8 per cent to a three-week low as local profit warnings underlined growth fears.

China's official factory purchasing managers' index, which tracks mainly big firms, inched up in September to 49.8 from 49.2 in August, reflecting the struggle by the world's second-biggest economy to regain strength.

HSBC's China PMI earlier showed overall factory activity shrank for an 11th consecutive month in September, suggesting the economy has almost certainly suffered a seventh straight quarter of slowing growth.

Beijing approved about $150 billion worth of infrastructure projects last month and has kept money markets liquid, but has refrained from cutting interest rates or the amount of reserves banks must hold since July.

In Japan, sluggish economic growth and the euro-zone's debt crisis hit sentiment among big manufacturers, which worsened in the third quarter, Bank of Japan data showed. South Korean exports to Europe fell 5.1 per cent from a year earlier while Indonesia, Southeast Asia's biggest economy, said exports in August tumbled 24.3 per cent from a year earlier.

The HSBC Taiwan PMI for September fell at its fastest rate in 10 months as export orders slumped.

Euro zone and US manufacturing surveys are due later today but the key statistic this week is Friday's US nonfarm payrolls, the first jobs data after the Fed's latest easing.

US crude fell 0.7 per cent to $91.57 a barrel and Brent fell 0.7 per cent to $111.61.
