SINGAPORE, June 2 (Reuters) - Oil fell below $72 on Wednesday in its third straight session of losses, as negative sentiment pervaded financial markets and investors favoured the safety of the dollar over riskier commodities.
Oil added to its drop of 1.9 percent on Tuesday, when China's purchasing managers index (PMI) showed the pace of manufacturing growth slowed in the world's second-largest oil consumer.
On Wednesday, Asian stocks fell while the dollar was up almost a third of a percent against a basket of currencies <.DXY>. The European Central Bank warned on Tuesday that the region's banks may face a new wave of losses.
"People are just really cautious and sentiment is bearish," said Tony Nunan, a risk manager with Tokyo-based Mitsubishi Corp.
U.S. crude for July <CLc1> fell 60 cents to $71.98 a barrel at 0648 GMT, down about 17 percent from a peak above $87 a month ago. ICE Brent <LCOc1> dropped 52 cents to $72.19.
"The thing that was keeping things lifted was China. I think we are getting a bit too concerned about one number," Nunan said, referring to Tuesday's PMI. "I think China demand is going to stay robust."
Stronger-than-expected U.S. construction and manufacturing data on Tuesday temporarily lifted stock markets and oil prices on Tuesday.
"I don't think the market will go much lower but it needs some time to regain power," said Keichi Sano, general manager of research at SCM Securities in Tokyo.
"Data in the U.S. is good and there is no reason to be so upset about the European credit issues," Sano said.
The market may take further direction from U.S. inventory reports scheduled for Wednesday and Thursday.
U.S. crude oil inventories were forecast to have slipped by 200,000 barrels last week as refineries increased crude processing and imports eased, a Reuters survey of analysts showed. [
]For gasoline, the forecast was for a drop of 500,000 barrels as supply was sent to secondary and tertiary sources ahead of the U.S. Memorial Day long weekend, which kick-starts the country's driving season running from late May through early September.
"The oil inventory reports might be able to change the sentiment of the market," said Sano.
Distillate stockpiles including diesel and heating oil were expected to have gained 300,000 barrels.
The industry group American Petroleum Institute will issue its report a day late on Wednesday at 2030 GMT, while government statistics from the U.S. Energy Information Administration will be published on Thursday at 1500 GMT, instead of the usual Wednesday release. (Editing by Michael Urquhart)
