Oil prices rose to near $99 a barrel on Monday in Asia, bouncing back from last week's plunge, as a weaker US dollar made commodities less expensive for investors with other currencies.

Some analysts are taking heart from a larger-than-expected increase in US jobs in April. Non-farm payrolls rose by 244,000 jobs in April, while the unemployment rate rose to 9.0% from 8.8% in March.
"The fundamental backdrop in the market remains entirely unaltered, with global oil demand still showing continued strength," Barclays Capital said in a report. "The general (oil price) trend from here should be higher, rather than lower."
Other analysts expect oil to drop as higher US gasoline prices up 37% from a year ago undermine crude demand. US gross domestic product growth slowed to 1.8% in the first quarter.
"Demand destruction already appears to be well under way in the US, reflected in the latest GDP data," Capital Economics said in a report. "We expect oil to fall further as the global economy slows, the dollar continues to rebound, and the risk premium due to unrest in the Middle East eventually fades."
