Iraq is now the biggest challenge for the already flooded oil market

Workers from Iraq near a pipeline, as it ejects oil at Al Tuba oil field in Basra, southeast of Baghdad. There's a bigger threat to oil prices than Iran.
Last week, Iran clinched a nuclear deal with several world powers that, among other things, will end an oil embargo and allow the country to increase production for export.
Analysts have begun to worry that the extra supply, which is estimated at up to 400,000 barrels a day. It could worsen the situation of the already oil flooded market. In a note to clients on Friday, however, JPMorgan analysts said Iraq was a bigger, more immediate concern to the market.
The firm elaborated: “Iran's agreement with the P5+1 solidifies the case of increased production in Q1. However, it is arguably additional supplies from Iraq that are pressuring world oil prices more than Iran at this juncture. Iraqi production has risen consistently over recent quarters, but surged ahead in 2Q2015 prompting us to conclude that Iraq will likely overtake Saudi Arabia as the biggest contributor to OPEC growth this year.”
The full potential of Iranian oil exports is not expected within the next year, as production infrastructure needs to be revamped. And so Iraq's surging production is a more immediate threat to oil prices, which last week fell for a third straight week.
On Monday morning, West Texas Intermediate crude futures were slightly lower, and fell to about $51 a barrel. Writing to clients on Friday, Deutsche Bank's Michael Hsueh noted that Iraqi output surged to a record high of 4.1 million barrels a day in June.
Hsueh also stated, "In comparison to other OPEC members, this means that Iraqi excess production at 920 kb/d above its inferred Iran Agreement quotas is second only to Saudi Arabia at 1,670 kb/d above quota."
