Oil prices inch up on Saudi commitment to cut output

Oil edged up on Tuesday after Saudi Arabia said it would strictly adhere to a commitment to cut output, but worries in financial markets about the outlook for crude supply dragged on prices.

"Many countries are actually going the extra mile and cutting beyond what they've committed ... I am confident about the impact ... and I am very encouraged about those first two weeks," Saudi Energy Minister Khalid al-Falih said late on Monday at an industry event in Abu Dhabi.

Under the agreement, OPEC, Russia, and other non-OPEC producers have pledged to cut oil output by nearly 1.8 million barrels per day (bpd), initially for six months, in order to bring supplies back in line with consumption.

Despite this, crude prices have fallen almost 5 percent since their early January peaks, as financial oil traders remain skeptical about OPEC's and Russia's willingness to fully comply with the cuts.

Analysts also said that steps to prop up oil prices through a cut in supplies could be self-defeating.

AB Bernstein said on Tuesday that the production cuts, and resulting higher prices, would likely hit oil demand.

"For each US$10 per barrel increase in oil prices, oil demand will decline by 10 basis points. While consensus expects demand growth of 1.3 million bpd in 2017 (vs 1.4 million bpd in 2016), we see risks to the downside as demand growth in China and India starts to moderate," Bernstein said.
