For more than 8,200 days, the Central Bank of Iraq's dollar auction — the foreign currency selling window — has sold the nation's oil dollars at a preferential rate to a closed circle of banks. More than $616 billion verified sold. At least $23.8 billion — likely near $29 billion — captured in the gap between the official rate and the market rate.
United States authorities have repeatedly tied participants in this mechanism to sanctioned banks and Iran-linked financial networks; its cost has been carried, every day, by the Iraqi public. The enforcement record
The Central Bank's own name for the mechanism is نافذة بيع العملة الأجنبية — the foreign currency selling window. It is publicly known as the CBI dollar auction: مزاد العملة, مزاد الدولار.
verified dollars sold at the window since 2004 — $515.0bn from recovered daily records plus $101.3bn from the CBI's own published annual totals
per-bank ledger rows recovered from the CBI's own session bulletins
documented margin captured between the window rate and the market rate since 2004 — approximately $28.8bn scaled to the verified annual volumes [estimate]
Daily figures have been recovered for 3,787 of the 8,240 days in the series; adding the CBI's own published annual totals brings the verified window figure to $616.3bn. The true total is higher still: 2018, 2020 and 2025 remain under-recovered. Tier A
The verified figure decomposes as $515.0bn from recovered daily records [Tier A] plus $101.3bn from the CBI's own published annual totals [Tier A] = $616.3bn. The margin: at least $23.8bn documented [Tier A]; approximately $28.8bn when the documented daily margin is scaled to the verified annual volumes [Tier B].
The mechanism
Iraq sells its oil through SOMO and is paid in dollars into an account at the Federal Reserve Bank of New York. The Ministry of Finance sells those dollars to the Central Bank of Iraq, which resells them each working day to a limited set of licensed banks at an official rate. Outside that window, the market pays more. The difference between the two prices is captured at the moment of purchase, and it is captured by whoever holds an allocation.
Repeated daily for two decades, that difference has functioned as a private levy on a public resource. Ali Allawi, finance minister until 2022, put the wider extraction from the state budget at 25 to 30 per cent; that estimate is attributed to him and is never mixed with the arithmetic on this site. This file assembles the Central Bank's own published record of the mechanism: what was sold, at what rate, and to whom.
The chain, in five stages
Iraq's wealth leaks at five distinct stages between the wellhead and the citizen. This file documents the two at the centre of the chain.
