Convicted after a five-week jury trial on 3 January 2018, and the most fully litigated commodity-barter sanctions case in the record.

The structure

Iran’s oil revenues were accumulating in accounts abroad that sanctions prevented it from repatriating or spending. The scheme released them.

According to the Department of Justice, Atilla — Deputy General Manager of International Banking at Türkiye Halk Bankasi, a Turkish state-owned bank — conspired with others “to provide access to restricted oil revenues through international financial networks, including U.S. financial institutions, to the government of Iran,” using Halkbank “to engage in transactions involving billions of dollars’ worth of petroleum revenues held by the Central Bank of Iran and the National Iranian Oil Company.”

Specifically, they “facilitated and protected the ability of gold trader Reza Zarrab to supply currency and gold to, and facilitate international financial transactions for, the Government of Iran, Iranian entities, and Specially Designated Nationals.”

The gold leg

Gold is doing something precise here, and it is the reason this case sits on the commodity barter page.

Iran had value it could not move as money. Gold is dense, universally accepted, priced against a public benchmark, and — crucially — carries no transaction record with it. Buying gold with blocked oil revenue in one jurisdiction and delivering it in another converts an immobilised balance into a bearer asset, without a single payment message that a screening system could read.

The trade is also large enough to be visible in aggregate. National import and export figures for gold are published, and a country whose recorded gold exports substantially exceed its production and imports is exporting metal it did not obtain by any recorded route — the arithmetic set out on the commodity barter page.

The food leg

The other half of the scheme is why this case also appears on the commodity misdescription page.

DOJ states that Atilla, Zarrab and others “conspired to create and use false and fraudulent documents to disguise prohibited transactions for Iran and make those transactions falsely appear as transactions involving food.”

Food and medicine were not prohibited. Humanitarian trade sat outside the restriction, so a transaction described as food purchased treatment reserved for a commodity class the transaction did not belong to.

That is exactly the mechanism the misclassification page describes — declaring goods in a category that attracts different treatment from the category they actually occupy — operating at the level of the commodity class rather than a six-digit tariff line. The control being escaped was an exemption rather than a licence requirement, and the direction of the fraud was into a permitted category rather than out of a monitored one.

Outcome

The jury convicted Atilla on five of six counts. He was sentenced to 32 months’ imprisonment. Halkbank itself was charged in the Southern District of New York in October 2019 for its participation in what DOJ described as a multibillion-dollar Iranian sanctions evasion scheme; that matter has generated extended litigation over foreign sovereign immunity and is not resolved. It was added by superseding indictment to the same docket opened for Zarrab in 2015 — Atilla, Zarrab and Halkbank were never three separate cases, whatever the DOJ press releases announcing each stage might suggest — and the docket itself is the more complete record of how the prosecution actually unfolded.

Techniques this case demonstrates

Programmes and jurisdictions in this case

  • Iran sanctions — A layered set of US, EU and UN measures dating from 1979 and substantially rebuilt after 2018, covering energy, finance, shipping, and proliferation-related procurement.
  • Türkiye — A large manufacturing and transit economy whose trade with several restricted destinations has grown substantially, making it central to third-country routing analysis.
