US Warns Iraq Over Iranian Proxy Forces and Blocks Cash Transfers

On April 22, 2026, the U.S. Treasury Department blocked a cargo plane carrying nearly $500 million in U.S. banknotes from reaching Iraq — money drawn from Iraq's own oil revenues held at the Federal Reserve Bank of New York [1][2]. The move marked the second dollar shipment suspended since the U.S.-Israel war with Iran began in late February, and it carried a blunt message: dismantle Iran's militia networks inside Iraq, or lose access to the financial system that keeps the Iraqi state running [2][3].

A State Department spokesperson framed the action in explicit terms: "The United States will not tolerate attacks on U.S. interests and expects the Iraqi government to immediately take all measures to dismantle the Iran-aligned militia groups in Iraq" [4]. But behind that demand lies a structural problem that two decades of U.S. policy have failed to resolve — and that Iraq's current political crisis makes more intractable than ever.

How the Dollar Lever Works

Iraq's financial dependence on the United States traces back to the 2003 invasion. Washington took control of Iraq's oil revenue management by depositing tens of billions of dollars in proceeds at the Federal Reserve Bank of New York [2]. More than two decades later, this arrangement persists: Iraq's oil revenues — which totaled approximately $102 billion in 2024, with oil accounting for 88% of total government revenue — still flow through New York before reaching Baghdad [5][6].

The mechanism gives Washington extraordinary leverage. Iraq's economy runs on oil sales denominated in U.S. dollars, and the Central Bank of Iraq depends on periodic dollar shipments to maintain currency stability and fund imports [7]. Government spending accounts for roughly 50% of GDP, making the public sector — including salaries for millions of civil servants, pensioners, and welfare recipients — directly dependent on dollar inflows [8].

When the U.S. suspends shipments, the effects ripple immediately. The Iraqi dinar, officially pegged at 1,300 per dollar for the 2026 budget, trades significantly higher in parallel markets [9]. Currency fluctuations drive up the cost of imported food and medicine, hitting hardest the more than 40% of Iraq's population living in poverty [7][10].

The Militia Problem: Embedded, Not Imported

Washington's demand that Baghdad "disband" Iran-aligned militias treats the problem as one of political will. The reality is more complicated. The Popular Mobilization Forces (PMF) — the umbrella organization housing most Iran-aligned armed groups — is not a foreign intrusion. It was created by an Iraqi government fatwa in 2014 to fight the Islamic State, was formally incorporated into Iraq's armed forces by parliamentary legislation, and its fighters draw government salaries [11][12].

By 2025, between 204,000 and 238,000 personnel were registered with the PMF, though actual numbers are believed to be higher [11]. The growth has been dramatic: pro-Iranian militias in Iraq expanded from roughly 4,000 fighters in 2010 to over 60,000 by 2014, and continued growing as they were integrated into state payrolls [13].

The major Iran-aligned factions within the PMF include:

• Kata'ib Hezbollah (KH): Designated a Foreign Terrorist Organization by the U.S. since 2009, KH operates the PMF's 45th, 46th, and 47th Brigades with an estimated 3,000–7,000 fighters. The IRGC's Quds Force finances, trains, and directs the group [14][15].
• Badr Organization: Iran's oldest proxy in Iraq, founded in 1982 and originally trained by the IRGC. Badr fields 18,000–22,000 troops within the PMF and holds significant political power through its leader, Hadi al-Amiri [16].
• Harakat al-Nujaba: A smaller but operationally aggressive faction also designated by the U.S. as a terrorist organization [16].

These groups are not simply armed formations operating alongside the state. Their commanders hold seats in parliament, control ministries, and wield veto power within the Coordination Framework — the Shia political alliance that dominates Iraqi governance [17]. Disarming them, as the Soufan Center analysis noted, would be "politically suicidal for any leader" given their "fervent support among large segments of the Shia population" [18].

Can Iraq Actually Comply?

The steelman case that Iraq's government is structurally unable — not merely unwilling — to rein in Iranian proxies rests on several pillars.

Constitutional integration: The PMF's legal status as part of Iraq's armed forces means disbandment requires parliamentary action. In March 2025, Prime Minister Mohammed Shia al-Sudani's government introduced a draft law to reform the PMF and subordinate it more firmly to the prime minister's authority. The effort collapsed by August 2025, withdrawn amid "external pressures and internal disagreements" [11][19].

Political composition: Pro-Iran militia commanders are not outside the political system — they are the political system, or at least a dominant part of it. The Coordination Framework, which selects Iraq's prime minister, includes parties directly affiliated with or sympathetic to Iran-aligned armed groups [17][18].

Caretaker government weakness: Al-Sudani has been operating with reduced powers as a caretaker since parliamentary elections more than five months ago. A caretaker government, by definition, lacks the mandate for the kind of sweeping security restructuring Washington demands [18].

Military capacity: Even if a prime minister ordered PMF disbandment, Iraq's conventional military lacks the capacity to enforce compliance against 200,000+ militia fighters who possess heavy weapons, territorial control, and popular constituencies [12][18].

Iraqi defenders of the government's position argue that compliance with U.S. demands would trigger exactly the civil conflict Washington claims to want to prevent. Critics of Iraq's government counter that Baghdad has never seriously attempted to assert sovereignty over the militias, instead allowing them to grow as a hedge against multiple threats — a deliberate ambiguity that served Iraqi leaders even as it enabled Iranian influence.

The Oil Crisis Multiplier

The dollar shipment freeze does not exist in isolation. Since the Strait of Hormuz closure on March 4, 2026, Iraq's economy has been in freefall [20]. Pre-war oil exports of approximately 3.5 million barrels per day have collapsed to an estimated 900,000 barrels per day, with the only remaining export route being a single pipeline to Turkey with a capacity of 300,000 barrels per day [20][21].

Oil production at Iraq's three main southern fields dropped 70% in the first weeks of the conflict [21]. With over 90% of government revenue derived from oil, the near-term insolvency risk is acute [18]. Economists warn Iraq faces a "dangerous crossroads" where restricted access to oil revenues could trigger "systemic salary shocks" for the millions of public sector workers who form the backbone of the economy [8][22].

The oil price surge — WTI crude rose from $55.44 in December 2025 to over $114 per barrel by mid-April 2026 — would normally benefit Iraq [23]. But higher prices mean nothing when the oil cannot reach market.

Iran's Alternative Financial Pipelines

Washington's dollar squeeze assumes that cutting off U.S. currency will sever Iran's financial lifeline through Iraq. Iran has spent years building alternatives.

Yuan-based trade: China purchases over 80% of Iran's seaborne oil exports, with payments settled in yuan through intermediaries and non-dollar banks [24]. Major Chinese automakers and metals firms operate barter systems with Iran, exporting car kits for assembly in exchange for oil [24].

Hawala networks: Informal money transfer systems move funds across borders through trusted intermediaries without formal banking records. Iranian businessmen use hawala networks connecting the UK, Turkey, and Dubai, with advances in cryptocurrency and blockchain making transactions increasingly difficult to trace [25].

Shadow banking: After 2018, Iran established small banks in Iraq, Armenia, and Afghanistan using local proxies to facilitate transactions disguised as domestic banking activity [25]. Iraq was a primary hub for smuggling U.S. dollars to Iran through local money changers until Washington curtailed Iraq's dollar access [25].

Cryptocurrency: Iran legalized Bitcoin mining partly to fund raw material imports, with some companies reportedly converting profits into Bitcoin for exchange abroad [25].

The effectiveness of these alternatives as a substitute for blocked dollar flows remains debated. U.S. officials argue the alternatives impose friction costs that reduce Iran's available resources. Analysts at the Foundation for Defense of Democracies have documented how China's role has "supercharged" Iran's sanctions evasion [24]. But Iran's militia funding has historically operated on relatively small budgets compared to state-level dollar flows, meaning even degraded alternative channels may suffice for proxy financing.

Historical Precedent: What Earlier Pressure Achieved

The current approach is not Washington's first attempt to use financial tools against Iran's influence in Iraq.

Under Obama, the strategy centered on diplomatic engagement. The 2015 JCPOA — the Iran nuclear deal — offered sanctions relief in exchange for nuclear program limits, with the implicit expectation that reduced tensions would moderate Iran's regional behavior [26]. The approach produced a nuclear agreement but did not measurably reduce Iran's militia presence in Iraq, which grew substantially during the same period as the PMF was formalized.

Trump's first term brought "maximum pressure" sanctions against Iran and the January 2020 drone strike that killed Qassem Suleimani, commander of the IRGC's Quds Force, while he was in Baghdad [26][27]. The killing was unprecedented — no previous administration had directly targeted a senior Iranian military leader. It produced a brief escalation cycle but no lasting reduction in militia activity. Pro-Iran groups continued to attack U.S. facilities, and the PMF's integration into Iraqi state structures deepened.

In 2023-2024, the Biden administration imposed stricter controls on Iraq's dollar auction system, barring multiple Iraqi banks from dollar transactions over concerns about currency diversion to Iran [10][28]. These measures contributed to dinar instability and public protests but did not fundamentally alter the militia landscape.

The current escalation goes further than any predecessor by simultaneously blocking physical dollar shipments, suspending security cooperation, and intervening directly in Iraq's prime ministerial selection [1][2][3].

The Government Formation Crisis

The dollar freeze is inseparable from the parallel political crisis. Iraq's parliamentary elections took place more than five months ago, but the Coordination Framework — the dominant Shia bloc — spent months deadlocked over its prime ministerial candidate [29].

Former two-time Prime Minister Nouri al-Maliki initially emerged as the frontrunner. Washington forcefully intervened: Trump warned that "all support to Iraq would stop" if Maliki returned to office, blaming him for the sectarian policies that fueled the 2014 Islamic State offensive [30][31].

On April 27, after Maliki withdrew under American pressure, Iraqi President Nizar Amedi named Ali al-Zaidi, a 40-year-old businessman and banker with no prior political office, as prime minister-designate [30][31]. Al-Zaidi — CEO of Dijlah TV and director of Al-Janoob Islamic Bank — now has 30 days to present a cabinet lineup requiring 167 parliamentary votes for confirmation [30].

The choice of an outsider businessman reflects both the intensity of U.S. pressure and the Coordination Framework's effort to find a candidate who might satisfy Washington without alienating Iran-aligned factions. Whether al-Zaidi can thread that needle — forming a government that excludes militia figures from cabinet posts while avoiding open confrontation with the groups that dominate his own political coalition — remains the central question.

What Washington Demands — and What It Hasn't Specified

Trump's special envoy for Iraq, Mark Savaya, declared that Washington plans to make 2026 "the year that marks the end of" militias, foreign interference, and uncontrolled weapons in Iraq [32]. The U.S. plans to complete its military withdrawal from Iraq by September 2026, adding a temporal dimension to the pressure [32].

But the specific benchmarks remain vague. U.S. officials told the Wall Street Journal that the dollar suspension was "temporary" but declined to specify what steps Iraq would need to take for deliveries to resume [2]. An Iraqi official reported that the Americans communicated the cash "will stop until forming the next government and arresting militia members for attacking the US embassy and troops in Iraq" [2].

The gap between rhetorical ambition — ending all militias in a single year — and operational specificity creates uncertainty for Iraqi leaders trying to calibrate a response. Arresting specific individuals responsible for embassy attacks is a different ask than dismantling the entire PMF, which employs hundreds of thousands and has constitutional standing. The absence of clear, graduated benchmarks risks pushing Iraq into a binary choice between full compliance (which could trigger civil conflict) and defiance (which could trigger escalating sanctions).

The 2008 Framework Under Strain

The 2008 Strategic Framework Agreement, signed in Baghdad and entering force on January 1, 2009, was designed to govern the "overall political, economic, cultural, and security ties" between the U.S. and Iraq [33]. A 2024 joint statement between the two governments committed to supporting the Central Bank of Iraq in transitioning from the wire auction mechanism to direct correspondent banking relationships by year's end [34].

The cash shipment freeze sits uneasily with these commitments. Iraqi officials have not publicly alleged a treaty violation, but the use of Iraq's own oil revenues as coercive leverage — revenue deposited in New York under arrangements dating to the post-invasion occupation — raises sovereignty questions that extend beyond the immediate militia dispute. France 24 described the dynamic bluntly: "Washington uses Iraq's own oil money to bend Baghdad to its will" [3].

What Comes Next

The convergence of dollar suspension, Hormuz closure, and government formation creates a situation with few precedents and multiple potential failure modes. Al-Zaidi's 30-day window to form a government coincides with the deepening economic crisis — an environment where concessions to Washington on militias could provoke armed resistance from groups that already view the new prime minister as an American imposition.

Iraq's central bank has stated it maintains "adequate US currency reserves," but has not specified how long those reserves could sustain operations without new shipments [2]. If the government formation process stalls or the resulting cabinet fails to satisfy Washington's demands, the next escalation steps — secondary sanctions, further financial restrictions, or accelerated troop withdrawal — would compound the economic damage already inflicted by the Hormuz crisis.

For ordinary Iraqis, the policy debate over militia integration and geopolitical alignment translates into a more immediate question: whether the government can continue paying salaries, stabilizing the currency, and importing the food and medicine on which the country depends. Over 40% of the population already lives in poverty [7]. The margin for economic error is thin, and shrinking.
