Security measures were intensified around Baghdad’s Green Zone in the early hours of June 28 as authorities detained nearly 50 individuals, including a dozen members of parliament and senior officials, amid a widening anti-corruption campaign. Substantial assets, including hundreds of millions of dollars in cash and gold, were also seized during the operation. The Green Zone, home to Iraq’s most critical government institutions and the US embassy, was locked down with heavy security forces, barriers, and razor wire, preventing those inside from leaving.

The crackdown is part of a broader effort launched by Iraq’s new prime minister, Ali al-Zaidi, who took office in May promising to tackle corruption and disarm pro-Iranian militias. Al-Zaidi, 41, a businessman with limited political experience, gained rapid popularity for pursuing what has been described as an unprecedented move within Iraq’s entrenched political landscape, where corruption has long been a systemic issue across parties and factions since 2003.

Al-Zaidi’s administration has targeted financial networks built by political parties, militia leaders, and businessmen, signaling to the broader political elite that no one is exempt from scrutiny. A government insider described the campaign as a "real earthquake" in political circles, representing a serious attempt to dismantle corruption that has become openly visible and deeply entrenched.

The prime minister emerged as a compromise candidate after protracted negotiations among major Shia political blocs and approval by the Trump administration, which viewed him as a potentially influential leader in the region. His appointment followed Iraq’s established muhasasa system, a power-sharing framework dividing government roles among Shia, Sunni, and Kurdish factions. However, muhasasa has also been blamed for fostering patronage networks and enabling political parties to control ministries as personal fiefdoms, often facilitating systemic fraud against state resources.

One of the campaign’s most high-profile arrests has been that of Adnan al-Jumaili, the former deputy oil minister appointed in 2025. Celebrated initially as a promising technocrat, al-Jumaili was taken into custody on May 30 and publicly arraigned. Investigators reported discovering large sums of cash, gold, ammunition, and approximately 40 properties tied to him. Further investigations uncovered additional assets concealed in various locations, with total seizures by mid-July reportedly including $96 million in Iraqi dinars, $24 million in cash, 375 kilograms of gold, numerous vehicles, and properties. Judicial authorities allege that al-Jumaili operated a vast corruption network, accumulating hundreds of millions through bribes, contract awards, and the diversion of fuel shipments. Al-Zaidi claimed al-Jumaili attempted to bribe him with $200 million to preserve his position.

The probe initially began in October 2025, uncovering financial irregularities connected to election spending and candidate funding. Al-Jumaili’s arrest led to a cascade of further detentions of figures tied to his network on June 28.

Observers indicate that the anti-corruption drive coincides with increased fiscal pressure from ongoing regional conflicts, as well as a growing role for the US in influencing Iraqi politics. Rather than direct engagement with politicians, the US has cultivated closer relations with the Iraqi judiciary, assisting investigations that balance high-profile exposure with preserving the overall post-2003 political order. Officials suggest al-Jumaili’s case was strategically chosen as it could generate significant domestic and international attention without destabilizing the broader system.

Skepticism remains over whether this latest campaign will enact deep, lasting reforms or serve as a temporary political maneuver. Some insiders emphasize the absence of guarantees that corruption will be eliminated or that political parties will cease diverting state resources. Nevertheless, government officials express hope for initiating a new phase in Iraq’s governance, one where basic services improve, public trust is restored, and the state begins to function more as a conventional government, with manageable successes and failures typical of any country.
