In the United States, which is not participating in any deal to hold back production, oil output has risen more than 10 percent over the past year to 9.3 million bpd, and the Energy Information Administration (EIA) expects that figure to rise above 10 million bpd in 2018. The IEA also forecast USA crude supply to grow by 430,000 bpd in 2017, and by 780,000 bpd in 2018, with many forecasting U.S. production to cap 10m bpd next year.
Both crude benchmarks have lost all the gains made at the end of a year ago after the Organization of the Petroleum Exporting Countries agreed with other big producers to cut output in an effort to prop up prices.
Oil prices have been under pressure in recent weeks as concern over rising US shale output offset production cuts by OPEC and non-OPEC members.

The bulk of the upward adjustment in non-OPEC oil supply since December "has come from the US", OPEC said.

"'Whatever it takes" might be the mantra, but the current form of "whatever' is not having as quick an impact as expected", the IEA said in a reference to Saudi Arabia's promise to do "whatever it takes" to rebalance oil supply and demand.
