The US controls key parts of Iraq’s oil revenue flow through a post-2003 financial arrangement centered on accounts held in the United States, giving Washington leverage over Baghdad’s access to dollars. Created after the 2003 US-led invasion to protect Iraqi oil wealth from creditors and support reconstruction, the system places Iraqi oil and gas receipts into accounts managed through the US Federal Reserve before transferring funds to Iraq’s central bank.

Under UN Security Council Resolution 1483 in May 2003, Iraqi oil and gas revenues are transferred to a special account in the name of the Central Bank of Iraq at the Federal Reserve. While the UN-backed framework ends in 2011 at Iraq’s request, revenues remain tied to the US-linked setup, including the IRAQ2 account at the New York Fed. Iraq also relies heavily on the dollar for trade and imports and carries significant unsettled external debts, which sources say complicate efforts to move funds.

Multiple outlets focus on how the arrangement can be used as pressure in US-Iran policy. In April, the US blocked about $500 million in cash shipments to Iraq tied to its own oil revenues; the shipment was later restored. Iraqis and economists cited by outlets argue the system offers creditor protections and facilitates oil sales, but also creates vulnerability to US decisions, including restrictions on physical dollars and compliance with US sanctions.
