Oil prices up on weaker dollar

LONDON: Oil prices rose for a fourth consecutive session on Tuesday boosted by a weaker dollar but worries over persistent oversupply capped gains.

Brent crude futures, the international benchmark for oil prices, gained 64 cents to $46.47 per barrel by 1152 GMT.

US West Texas Intermediate (WTI) crude futures were up 56 cents at $43.94 per barrel.

The gains mean the market is up slightly so far this week, after spending much of the last month in negative territory.

The Organization of the Petroleum Exporting Countries (OPEC) and its partners have tried to reduce a global crude glut with production cuts. OPEC nations and 11 other exporters agreed in May to extend cuts of 1.8 million barrels per day (bpd) until March.

Despite the cuts, which started in January, inventories have not fallen as expected, as US producers and others outside the OPEC-led regime have boosted output.

Ian Taylor, head of the world’s largest independent oil trader Vitol, told Reuters that Brent prices would stay in a range of $40-$55 a barrel for the next few quarters.

“In the third quarter we should draw, but we are unsure about the fourth quarter as US production is likely to have a year-end spurt,” Taylor added.

OPEC members Nigeria and Libya are exempt from the cuts and have raised production substantially.

OPEC member Iran has also been allowed a small increase to recover market share lost due to Western sanctions.

US production has risen about 10 percent since last year to 9.4 million bpd, with the number of US oil rigs in operation at the highest in more than three years.
