OPEC Output Reaches 3-Year High as Iran Pumps Most Since 2012

OPEC pumped the most crude last month in more than three years as Iran restored output to the highest level since international sanctions were strengthened in 2012.

The Organization of Petroleum Exporting Countries, responsible for 40 percent of world oil supplies, raised output by 100,700 barrels a day to 31.5 million last month, the group said in its monthly market report, citing external sources. This increase came even as Saudi Arabia, which often curbs output toward the end of peak summer demand, told OPEC it cut production by the most in almost a year.

Oil prices slumped to a six-month low below $50 a barrel in London last week as rising OPEC supplies, resilient U.S. production and concerns over Chinese demand prolong a global glut. Iran reached an accord with world powers on July 14 that may ease sanctions on its oil exports later this year in return for curbing nuclear activity.
