OPEC and allies extend oil supply cut in bid to boost prices

OPEC and its allies led by Russia agreed to extend oil output cuts until March 2020 on Tuesday seeking to prop up the price of crude as the global economy weakens and US production soars.

The alliance, known as OPEC+, has been reducing oil supply since 2017 to prevent prices from sliding amid increasing competition from the United States, which has overtaken Russia and Saudi Arabia to become the world's top producer.

Benchmark Brent crude has climbed more than 25 percent so far this year after Washington tightened sanctions on OPEC members Venezuela and Iran, causing their oil exports to drop.

The approval of the pact extension on Tuesday follows a decision by OPEC producers the previous day.

Fears about weaker global demand as a result of a US-China trade spat have added to the challenges faced by the 14-nation Organization of the Petroleum Exporting Countries.

The OPEC+ extension comes after Russian President Vladimir Putin said on Saturday he had agreed with Saudi Arabia to prolong the pact and continue to cut combined production by 1.2 million barrels per day, or 1.2 percent of world demand.

Oil prices could stall as a slowing global economy squeezes demand and US oil floods the market, a Reuters poll of analysts found.

Saudi Energy Minister Khalid Al-Falih said on Monday he was growing more positive about the global economy after a G20 meeting of world leaders over the weekend.

"The global economy in the second half of the year looks a lot better today than it did a week ago because of the agreement reached between President Trump and President Xi (Jinping) of China and the truce they have reached in their trade and the resumption of serious trade negotiations," Falih said.

The meeting on Tuesday also agreed on a charter for long-term cooperation between OPEC and non-OPEC producers.
