Oil rose on Thursday, a day after hitting 10-month lows, but market sentiment remained negative because the global crude glut has persisted despite OPEC-led output cuts.

Brent crude futures ended 40 cents higher to US$45.22 a barrel, after falling as low as US$44.53. Brent fell 2.6 per cent the previous session to US$44.35, lowest since November.

U.S. crude futures ended up 21 cents a barrel at US$42.74 a barrel. On Wednesday, they hit a low of US$42.05, their lowest intraday level since August 2016.

Crude has dropped around 20 per cent since late February, erasing gains after OPEC and other countries agreed to cut crude output 1.8 million barrels per day (bpd) for the first six months of 2017.

Last month, the Organization of the Petroleum Exporting Countries and other producers extended the output cut deal for nine months. But the global crude glut has persisted, with output rising in Libya and Nigeria, OPEC members exempt from the cuts.

The price slide has tested OPEC's pledge to do "whatever it takes" to support oil prices.

"We think it is lower for longer and rallies should be sold," said Tariq Zahir, crude trader and managing member at Tyche Capital Advisors in New York.

In the United States, heavy oversupply in gasoline stocks has caused demand on the Colonial pipeline to hit a six-year low.

Crude output is still increasing in the United States, where some shale producers can profit even if oil prices drop below US$40 a barrel.

Oil stocks in Europe's Amsterdam-Rotterdam-Antwerp hub hit 64.2 million barrels in the week to June 16, the highest in a year, according to data from industry monitor Genscape.

"‎The question is whether OPEC will respond with further cuts or whether it needs to look again at its macro strategy for addressing low prices," Michael Burns, oil and gas partner at law firm Ashurst, said.

Iraq Oil Minister Jabar al-Luaibi said oil prices should start recovering by the end of July, to reach US$54 to US$56 a barrel by the end of the year.

Tropical depression Cindy disrupted some operations in the Gulf of Mexico, home to about 17 per cent of U.S. crude and 5 per cent of dry natural gas output, supporting markets modestly. However, the storm is on the wane, even though heavy rains still threaten several U.S. Gulf states.
