Reza Zarrab

Reza Zarrab is a Turkish-Iranian gold trader who pleaded guilty in the United States in 2017 to seven counts connected with evasion of US measures against Iran. His admitted conduct, later testimony, Mehmet Hakan Atilla's conviction and the corporate case against Türkiye Halk Bankası A.Ş. (Halkbank) are separate legal records.

Admitted scheme

Zarrab admitted participation in arrangements that moved Iranian funds through Turkish and international financial channels. Court and prosecution records describe oil and gas proceeds held in Türkiye, gold transactions, purported food trade and dollar payments routed through US correspondent banks. The mechanism is treated at Iranian gas-for-gold scheme and the Halkbank prosecution (2012-2026). Amounts should be taken from the relevant plea, indictment or judgment and identified as admitted, alleged or adjudicated.

The guilty plea establishes Zarrab's own criminal responsibility to its terms. His trial testimony about Turkish officials was evidence given by a co-operating witness. It did not itself convict the people he named. The jury separately convicted Atilla, then a Halkbank deputy general manager, in January 2018. That verdict should not be described as Zarrab's conviction or a corporate conviction of Halkbank.

Halkbank proceedings

The United States indicted Halkbank in October 2019. The bank contested jurisdiction and immunity before trial. In Türkiye Halk Bankası A.Ş. v United States, 598 U.S. 264 (2023), the Supreme Court held that the Foreign Sovereign Immunities Act did not supply criminal immunity and remanded the common-law question. In October 2024, the Second Circuit held that common-law foreign sovereign immunity did not protect Halkbank from the charged prosecution. The Supreme Court denied a further petition on 6 October 2025. These rulings concerned whether the prosecution could proceed, not whether the indictment's allegations were true.

The case later changed posture. Halkbank and US prosecutors entered a deferred prosecution agreement in March 2026. Halkbank's official disclosure states that the US District Court approved the parties' joint dismissal request on 17 June 2026. As at 30 July 2026, the corporate prosecution was therefore no longer pending. The dismissal was not a trial verdict on the merits and did not reverse Zarrab's plea or Atilla's conviction.

Strategic significance

Zarrab operated as a private intermediary and adapter within a state-scale evasion architecture. The case shows how commodity trade, humanitarian exceptions, bank documentation and correspondent access can be combined to move restricted value. It also shows the evidentiary value of a co-operating insider, while demanding strict boundaries between admissions, allegations and verdicts.

Those boundaries remain essential to fair attribution.

Sanctions evasion as system design captures the network logic; Gold-flow and bullion denial captures one control point. Neither concept establishes that every Turkish or Iranian official, bank employee or trader joined the scheme. Current court status, corporate disclosures and any later sentencing record should be refreshed on publication day.
