Through its 80 known oil fields, Iraq is estimated to have almost 10% of the world's proven reserves  (143 billion barrels) and 2% of the world’s natural gas reserves, making it the largest EITI implementing country by oil and gas reserves. The Rumaila and West Qurna fields together hold more proven oil reserves than the entire United States. According to the International Energy Agency, Iraq has the potential to earn USD 5 trillion in oil revenues between 2013 and 2035. For the same time period, it is estimated that Iraq will provide 45% of global production growth and become the world's second largest exporter of oil. Internal conflict and cut-backs in investment due to low oil prices are among the factors hampering Iraq's ability to reach this potential.

In Baghdad-administered Iraq, the industry is completely state-owned, with the oil marketing company SOMO selling crude to 40 accredited international companies on behalf of four producing companies, South Oil Company, North Oil Company, Missan Oil Company and Midland Oil Company. According to the latest IEITI Report, over 2.1 million barrels per day were produced in 2014. The eleven international Technical Service Contracts (TSCs) that have been signed hold the promise of a total production of over 13 million barrels per day. If this figure were ever achieved, Iraq would become the largest oil producer in the world. The current goal of the Ministry of Oil is to reach a production capacity of 7 million barrel per day by 2020.

Iraq's GDP growth slowed to 1.1% in 2017, a marked decline compared to the previous two years as domestic consumption and investment fell because of civil violence and a sluggish oil market. The Iraqi Government received its third tranche of funding from its 2016 Stand-By Arrangement (SBA) with the IMF in August 2017, which is intended to stabilize its finances by encouraging improved fiscal management, needed economic reform, and expenditure reduction. Additionally, in late 2017 Iraq received more than $1.4 billion in financing from international lenders, part of which was generated by issuing a $1 billion bond for reconstruction and rehabilitation in areas liberated from ISIL. Investment and key sector diversification are crucial components to Iraq’s long-term economic development and require a strengthened business climate with enhanced legal and regulatory oversight to bolster private-sector engagement. The overall standard of living depends on global oil prices, the central government passage of major policy reforms, a stable security environment post-ISIS, and the resolution of civil discord with the Kurdish Regional Government (KRG).
