How Iran Sanctions Affect UAE Companies

Short answer

UAE companies with Iranian counterparties are exposed to sanctions risk from three separate frameworks simultaneously: UAE domestic obligations administered by the Executive Office for Control and Non-Proliferation (ECON), United Nations Security Council sanctions reimposed in September 2025, and US OFAC measures that apply extraterritorially to any transaction touching the US financial system. These frameworks do not operate in sequence. A company can be compliant with UAE domestic requirements and still face US sanctions exposure if its transactions involve US dollar clearing or American counterparties. Bank accounts in the UAE are being frozen and corporate accounts are being refused where Iranian counterparty links are identified. This applies to trade in goods, financial flows, and commodity transactions. The risk is materially higher in 2026 than it was twelve months ago.

Who this applies to

This article applies to:

• UAE mainland and free zone companies that trade goods with, or receive payments from, Iranian entities
• Logistics and shipping companies that carry goods to or from Iran, or that deal with Iranian-flagged or Iranian-beneficiary vessels
• Financial services firms, exchange houses, and currency traders handling transactions that involve Iranian nationals or entities
• Individuals who hold accounts at UAE banks and who have transferred funds to Iranian accounts or who have Iranian business partners

It does not address purely personal remittances between private individuals with no commercial dimension, though those transactions can still trigger enhanced due diligence reviews at the bank level.

Three sanctions frameworks operating simultaneously

Most UAE businesses with Iranian exposure think about sanctions in terms of a single list to screen against. The actual structure is more complex, and the gap between the frameworks is where enforcement risk concentrates.

UAE domestic obligations. The UAE implements United Nations sanctions through internal directives administered by ECON, established under Cabinet Resolution No. 15 of 2022. ECON maintains the UAE sanctions list and coordinates with the Financial Intelligence Unit and the Central Bank. Under the AML framework, every financial institution, exchange house, and designated non-financial business in the UAE is legally required to screen customers and transactions against the UAE sanctions list. Where a match or reasonable suspicion arises, the entity must freeze assets immediately and file a Suspicious Activity Report with the FIU. The UAE AML regime, overhauled by Federal Decree-Law No. 10 of 2025, significantly strengthened these obligations from October 2025 onwards.

UN Security Council sanctions. On 28 September 2025, following the activation of the snapback mechanism under UNSC Resolution 2231, the Security Council reimposed a range of sanctions on Iran after determining that Tehran had engaged in significant non-performance of its nuclear obligations under the JCPOA. The snapback mechanism, triggered by France, Germany, and the United Kingdom on 28 August 2025, cannot be blocked by a veto once the 30-day window runs. The restored measures revive restrictions on nuclear-related equipment, arms transfers, petroleum and petrochemicals, gold and precious metals, and financial dealings with designated Iranian entities. The EU and UK implemented parallel measures on 28 and 29 September 2025 respectively. As a UN member state, the UAE is obligated to implement these measures, and ECON administers that implementation domestically. The UN Security Council sanctions list is the source document.

US OFAC extraterritorial reach. The United States maintains a separate and comprehensive Iran sanctions regime through the Office of Foreign Assets Control. These sanctions apply to US persons and to any transaction that touches the US financial system, including US dollar-denominated transactions cleared through US correspondent banks. Non-US companies, including UAE-registered entities, can be sanctioned by OFAC for providing material support to designated Iranian entities. OFAC designated more than 875 persons, vessels, and aircraft in 2025 alone as part of a declared campaign of maximum pressure on Iran. Several of those designations targeted UAE-registered companies directly.

What the UN snapback means for UAE companies in practice

The reimposition of UN sanctions in September 2025 changed the legal position for companies that had been trading with Iran on the basis that JCPOA-era sanctions relief remained in force. That relief no longer exists. The following categories of activity are now subject to renewed restrictions for all UN member states:

• Sale or supply of nuclear-related equipment or technology to Iran
• Arms transfers to or from Iran
• Trade in petroleum, petrochemicals, and petroleum products with designated Iranian entities
• Transactions involving gold, precious metals, and certain metals with designated Iranian entities
• Financial dealings, including providing banking services, to designated Iranian banks and entities, including Bank Melli and the Central Bank of Iran

Certain transactions were subject to wind-down periods that expired in January 2026. Companies that relied on those wind-down provisions and have not restructured their arrangements since are now operating without that protection.

How UAE banks are responding

UAE banks are required by law to screen against the ECON sanctions list and to apply enhanced due diligence to high-risk relationships. In practice, many major UAE banks have gone considerably further, adopting internal policies that restrict or exit relationships with Iranian-connected clients entirely, partly to manage US correspondent banking risk and partly in response to the heightened scrutiny following the UAE's removal from the FATF grey list in February 2024 and the upcoming FATF mutual evaluation anticipated for June 2026.

The practical consequences for businesses with Iranian exposure include:

• Account closures without detailed explanation. Banks are legally prohibited from disclosing that a Suspicious Transaction Report has been filed. Vague references to "compliance requirements" are not evasiveness but a statutory obligation.
• Transaction blocks on incoming or outgoing payments where Iranian entities appear in the payment chain, even as intermediaries.
• Requests for enhanced documentation on the source of funds, the ultimate beneficial owner, and the commercial purpose of transactions.
• Rejection of new account applications from companies with Iranian shareholders, directors, or counterparties, or from individuals holding Iranian passports.

As of early March 2026, the UAE government is also reported to be evaluating broader financial measures against Iranian assets held within the UAE banking system, including targeted freezes on shadow companies used to facilitate Iranian trade and restrictions on currency exchanges that move funds outside regulated banking channels. No formal decision has been announced, but the direction of travel is clear.

OFAC and the secondary sanctions risk for UAE companies

The extraterritorial reach of US sanctions creates a layer of risk that is independent of what UAE law requires. A UAE company does not need to have a US presence or US shareholders to be exposed to OFAC action. If the company processes US dollar transactions, uses US financial infrastructure, or transacts with entities that have US connections, OFAC has the authority to designate it.

OFAC has used that authority against UAE-registered entities directly. In recent designations, multiple UAE free zone companies were added to the Specially Designated Nationals and Blocked Persons list for purchasing Iranian petroleum products, acting as financial front companies for designated Iranian banks, and facilitating oil export transactions for the National Iranian Oil Company. The companies involved included entities registered in DMCC, SHAMS, and other UAE free zones. Several were registered as trading companies with licenses that did not disclose the nature of their Iranian counterparty relationships.

The civil penalty for an OFAC violation is the greater of USD 302,584 per violation or twice the amount of the underlying transaction. Criminal penalties for wilful violations extend to USD 1 million and 20 years' imprisonment. These are US penalties, but they are enforced through correspondent banking restrictions and asset blocking that affect any company doing business in dollars globally.

What sector exposure looks like in practice

What companies should do now

The compliance obligations arising from this framework are not static. The FATF mutual evaluation anticipated for June 2026 will intensify UAE regulatory scrutiny of businesses with Iranian exposure in the months leading up to it. Companies that have not conducted a sanctions gap assessment since September 2025, when the UN snapback took effect, are working from an outdated baseline.

The minimum steps for any company with existing or historical Iranian counterparty relationships are:

• Screen all current and recent counterparties against the ECON, UN, and OFAC sanctions lists. These lists are not identical. A counterparty not on the UAE domestic list may still appear on the OFAC SDN list.
• Review any contracts, trade finance arrangements, or ongoing payment obligations involving Iranian entities and assess whether wind-down provisions have expired.
• Assess whether any transactions processed through your UAE accounts in the last two years involve Iranian-origin funds, even indirectly, and document the basis on which enhanced due diligence was or was not conducted at the time.
• If your company trades in petroleum, petrochemicals, metals, or technology, obtain a specific legal assessment of the end-use risk across your counterparty chain, not only your direct counterparties.
