Oil prices rose on Monday, buoyed by output cuts by OPEC and reports that the United States and China are close to a deal to end a year-long tariff row. Men at work International Brent futures were at 65.25 dollars a barrel at 07:13 GMT, up 18 cents, or 0.3 per cent, from their last close. U.S. West Texas Intermediate (WTI) crude futures were at 55.94 dollars per barrel, up 14 cents or 0.3 per cent. The U.S. and China appeared close to a deal that would roll back U.S. tariffs on at least 200 billion dollar worth of Chinese goods. Beijing has also pledged structural economic changes and elimination of retaliatory tariffs on U.S. goods, a source briefed on negotiations said on Sunday in Washington. Hopes of an end to the trade spat between the two world’s biggest economies added support to a market that has been rallying for the past two months on cuts to production. The “substantive progress” China and the U.S. have made in their trade talks has been “well-received” in both countries and around the world, a senior Chinese official said on Monday. Supply from OPEC fell to a four-year low in February, a Reuters’ survey found, as top exporter Saudi Arabia and its allies over-delivered on the group’s supply pact while Venezuelan output registered a further involuntary decline. “OPEC exports are off by over 1.5 million barrels per day (bpd) since November,” Barclays bank said in a note released on Sunday. “The supply picture looks generally tighter this year,” said energy analysts at Fitch Solutions in a note on Monday, adding they expected Brent to average 73 dollars per barrel in 2019. Oil prices have been further pushed up by U.S. sanctions against OPEC-members Iran and Venezuela, which Barclays bank estimates to have resulted in a reduction of around 2 million bpd in global crude supply. In the U.S., there are signs that the oil production boom of the past years, which has seen crude output rise by more than 2 million bpd since early 2018 to more than 12 million bpd, may slow down. U.S. energy firms last week cut the number of oil rigs looking for new reserves to the lowest in almost nine months as some producers follow through on plans to cut spending despite an over 20 per cent increase in crude futures so far this year. Oil price tumbles after Trump tells OPEC to ‘relax’ In spite this, Barclays said “we believe that there could be a repeat performance in the second-half of this year” for U.S. oil output.
