US crude oil futures gained as weak US jobs data did little to dampen investors' improved appetite for risk.
US light crude for May delivery was up $1.08 at $53.59 a barrel by 5.02am. The contract ended 13 cents lower to settle at $52.51 on Friday, as a bounce in Wall Street countered an earlier slide set off by gloomy jobs data.
London Brent crude rose 71 cents to $54.18 a barrel.
“Markets are having greater optimism about the international economy and that is giving a lift to the commodities markets,” said David Moore, a commodities strategist at the Commonwealth Bank of Australia.
“The fact that investors had shrugged off the gloomy jobs data on Friday is indicative that the focus has now shifted to a global recovery.”
Although crude oil prices have risen roughly 16 per cent so far this year, they are still about 63 percent below their high of more than $147 a barrel last July.
US stocks rose on Friday, with the Dow closing out its best four-week winning streak since 1933, lifted by robust results from Research in Motion and after Federal Reserve Chairman Ben Bernanke said the central bank would do everything it could to stabilise banks.
The gains came despite government data showing US employers slashed 663,000 jobs in March, lifting the unemployment rate to a 26-year high of 8.5 per cent. Some analysts said the jobless number came in within expectations and had already been priced in.
Analysts said investors may attempt to push oil towards the $55 mark this week, should US stocks should rally further on signs that the economic slump is abating and if earnings season does not get off to a rocky start.
Oil rose nearly 11 per cent last month and snapped two straight quarters of double-digit decline to rally 9.5 per cent in the first quarter, thanks to a rally in global stock markets and OPEC's production cuts.
