Singapore: Oil prices fell in Asia today as dealers eyed lacklustre manufacturing data from China, which raised concerns about weak demand from the world's top energy consumer, analysts said.
US benchmark West Texas Intermediate fell 27 cents to USD 58.88 while Brent eased 13 cents to USD 66.33 in mid-morning trade.
Financial markets in Japan, Thailand and Malaysia were closed for a public holiday.
Analysts said oil prices were tracking losses in Asian equity markets in reaction to data from global banking giant HSBC showing China's manufacturing activity slipped to a 12-month low in April.
HSBC today said its final purchasing manager's index (PMI) for the manufacturing sector fell to 48.9 in April, weakening from 49.6 in March, and the weakest since 48.1 in the same month last year.
The index, compiled by information services provider Markit, tracks activity in China's factories and workshops and is regarded as a barometer of the health of the Asian economic giant.
A PMI reading above 50 indicates growth, while anything below signals contraction.
"Today's downbeat PMI reading suggests that underlying economic momentum has continued to soften," said Julian Evans-Pritchard, China economist at research house Capital Economics.
Sanjeev Gupta, head of the Asia-Pacific oil and gas practice at business consultancy firm EY said oil prices were retaining some support due to "geopolitical concerns over the crisis in Yemen".
