What Are the Latest Updates on the New US Economic Restrictions on Iran?

There have been four US sanctions actions aimed at Iran since late July, and they are easier to follow if you stop treating them as one thing. They use two different legal authorities, they target three different kinds of network, and the most significant of them changed a legal classification rather than adding names to a list.

Here is what each one did, in order, and what a designation actually does once it lands.

What has the US done to Iran most recently?

Five actions in under five weeks. The most recent, on 24 August, is the largest: Treasury named it Operation Economic Outcast and used it to add five new sectoral determinations rather than only new names. The four before it moved from shipping to aviation to banking to cash couriers.

The 24 August action is covered separately in Operation Economic Outcast , because it does something the other four do not: it expands who can be sanctioned in future without a further announcement.

The pace is the point as much as the content. OFAC’s Recent Actions feed listed 3,145 actions in total at the time of writing, across every sanctions programme it runs; four Iran-related entries inside a month is a concentrated run.

What did the 20 August action actually change?

It re-designated Hizballah as a group owned, controlled or directed by Iran’s IRGC-QF. That is different in kind from the rest of the list. Hizballah has been a Specially Designated Global Terrorist since 31 October 2001; what changed is the stated basis for the designation.

Treasury’s reasoning, in its own words, rests on the IRGC-QF’s coordination of Hizballah attacks and its involvement in directing the group’s political decision-making. In legal terms the group is now designated for acting on Iran’s behalf, not only for its own conduct.

The same action named a cash-smuggling network. Treasury identifies the Turkish businessman Yunus Alper Yilmaz as running couriers who move cash to Hizballah’s base in Lebanon, using Türkiye-based exchange houses as fronts and supplying front companies and bank accounts for IRGC-QF transfers. Couriers Halil Ibrahim Kacmaz and Onder Dede are named alongside him, with seven further individuals designated in the same round. Treasury adds that the network was once associated with Behnam Shahriyari, an IRGC-QF finance official who is now dead.

What happened on 7 August?

Two separate actions on the same day, one against banking and one against crypto. The State Department published both under its own headings.

The first, which it called severing Iran’s illicit cash pipeline, went after currency exchange houses and shell companies that State says helped Iran move hundreds of millions of dollars through the international financial system, reaching banks, exchange houses and individual facilitators. State describes it as OFAC’s eighth action of 2026 against Iranian shadow banking.

The second hit digital assets: six entities and one individual, including two exchanges. Treasury names Siavash Kayvanpour — born in Iran, additionally a citizen of Dominica and Afghanistan, resident in the UAE — as operating the Shelbit Exchange through a Georgia-registered company, and says Shelbit serviced a Persian-language gambling network through which tens of millions of dollars in digital assets were laundered. The action was developed with IRS Criminal Investigation.

State gave an explicit trigger for the timing, saying the actions followed Iranian attacks on commercial vessels in the Strait of Hormuz earlier that week.

Alongside the designations, the State Department’s Rewards for Justice programme is offering up to $15 million for information leading to the disruption of the financial mechanisms of the IRGC and its branches. Both Treasury and State repeat the offer in their 7 August releases, which is a reasonable signal of where the effort is now concentrated: not on Iran’s institutions directly, but on the people who move money for them.

What were the late-July actions?

One on shipping through the Strait of Hormuz, one on Mahan Air. They are the two with the widest commercial reach.

On 29 July Treasury designated two firms behind what it describes as an IRGC-backed scheme forcing commercial vessels to buy mandatory services to pass through the Strait of Hormuz: the Persian Gulf Marine Insurance Company and HormuzSafe Marine Services Authority, both established by Iran’s state insurer. Several vessels carrying Iranian crude and petrochemicals were sanctioned alongside them. Treasury says it has now sanctioned more than 100 vessels tied to Iran’s shadow fleet since the start of the year.

On 30 July it designated six entities and individuals across China, India, Russia and Iran, most of them general sales agents for Mahan Air — the airline that sells and books cargo and passenger capacity on its behalf in each market. Treasury’s stated basis is that Mahan Air carries IRGC-QF personnel for military training and has helped move drones and weapons.

Which legal authorities are these under?

Two orders, doing different jobs. Knowing which applies tells you what the designation actually prohibits.

Executive Order 13902 covers people operating in Iran’s financial and petroleum sectors. It was used for the Hormuz action and the shadow-banking action.

Executive Order 13224 is a counterterrorism order aimed at terrorist groups, their supporters and those who aid acts of terrorism. It was used for Mahan Air, for part of the crypto action, and for the whole of 20 August.

Both are described by Treasury as advancing National Security Presidential Memorandum 2, the directive that sets the current maximum pressure policy. Treasury Secretary Scott Bessent refers to the economic campaign as Economic Fury.

Who has actually been sanctioned?

Mostly people and companies outside Iran. That is the practical shape of these rounds and the part most easily missed.

The named parties across the four actions sit in Türkiye, China, India, Russia, Georgia and the United Arab Emirates, along with Iran itself. They are couriers, travel agents, exchange houses, shell companies, crypto platforms and vessels — intermediaries rather than Iranian state bodies. The stated logic each time is that they provide a service Iran cannot easily replace.

What does a designation mean in practice?

All of the designated party’s property under US control is blocked, and the block extends automatically to companies they half-own. Treasury sets this out in standard language on each action.

Once a person is designated, all property and interests in property in the United States, or in the possession or control of US persons, are blocked and must be reported to OFAC. Any entity owned 50 percent or more — directly or indirectly, individually or in aggregate — by one or more blocked persons is blocked too, without needing to be named.

Two further points carry weight for anyone doing compliance. Violations can bring civil or criminal penalties against both US and foreign persons, and OFAC may impose civil penalties on a strict liability basis, meaning intent is not required. Treasury also warns that financial institutions and others may risk exposure to sanctions themselves for certain transactions with designated persons. For the digital asset side it points readers to its FAQ 1250 and FAQ 1257, the second of which was amended in the 7 August round.

Is there any sign of this easing?

Nothing in the published record suggests it. The four actions run in one direction, and the documents describe an intent to continue rather than to wind down.

There is also no indication of movement at the United Nations level: the State Department’s Iran sanctions page carries no reference to snapback, to Security Council Resolution 2231, or to any return of UN measures.

If you need the current position rather than this snapshot, OFAC’s Recent Actions feed is the authoritative list and is updated as each action lands; the 20 August press release sets out the Hizballah re-designation in full. This page reflects the record as of 24 August 2026, and a programme moving at four actions a month will not stay still for long.
