Oil extends losses on worry over possible supply increase from OPEC

TOKYO (Reuters) – Oil prices fell more than 1% on Tuesday, extending losses that began last week, as investors unwound long positions on concern that OPEC may agree to increase global supply in a meeting this week and Chinese demand may be slipping.

Brent crude dropped 78 cents, or 1.2%, to $62.91 a barrel by 0138 GMT, after losing 1.1% the previous day. U.S. West Texas Intermediate (WTI) crude slid 74 cents, or 1.2%, to $59.90 a barrel, having lost 1.4% on Monday.

Investors are worried the Organization of the Petroleum Exporting Countries and its allies, a group known as OPEC+, will boost oil output, said Hiroyuki Kikukawa, general manager of research at Nissan Securities.
