NEW YORK: Oil prices rose to a near three-year high on Friday and headed for a third straight week of gains, supported by global output disruptions and inventory draws.

The rally was slightly dampened by China’s first public sale of state crude reserves.

Brent climbed 53 cents, or 0.7%, to $77.78 a barrel by 10:40 a.m. EDT (1440 GMT), while US West Texas Intermediate (WTI) crude rose 40 cents, or 0.6%, to $73.70.

Brent is on track for its highest close since October 2018 for a second day in a row and WTI is on track for its highest close since July this year, also for a second day.

Some members of the Organization of the Petroleum Exporting Countries and their allies, known as OPEC+, have also struggled to raise output due to under-investment or maintenance delays during the pandemic.

Iran, which wants to export more oil, said it would return to negotiations soon on resuming compliance with a 2015 nuclear deal with world powers. It did not give a date.

Brent could hit $80 by the end of September due to stock draws, lower OPEC production and stronger Middle East demand, UBS analysts wrote.

But China’s first public sale of state oil reserves capped crude price gains. PetroChina and Hengli Petrochemical bought four cargoes totaling about 4.43 million barrels, sources said.
