Key takeaway

Refusal became the starting point for every Iran licence request that is not legally compelled.

The Office of Foreign Assets Control (OFAC) adopted a presumption of denial for Iran-specific licence applications on Thursday 10 September, and Treasury said its Licensing Division began refusing most outstanding requests immediately⁠¹. Two exceptions survive: approvals the law compels, and cases touching safety, meaning life, limb or environmental harm⁠².

A licence application is how anyone with a lawful reason to touch a sanctioned economy asks permission. A family sending a remittance to a relative in Tehran files one. So does a hospital importing a component, a university paying a conference fee, and an operator seeking a certified aircraft safety part. Until Thursday each of those was assessed on its merits, and Treasury carried the argument for refusing. Now the applicant carries the argument for approval, and must show its transaction fits one of two narrow exceptions.

The change completes a sequence that began on Monday 24 August with the indefinite stay of five Iran general licences, whose wind-down expired on 8 September. Removing those licences pushed every affected transaction into the application queue. The 10 September policy sets the default answer in that queue to no. Taken together, the two steps mean a remittance, a conference fee and a spare part now travel the same route and meet the same presumption.

This is also the most durable of the week's American actions, and the least visible. It carries no expiry date, it was published in a paragraph, and it inverts the default of a whole country programme without amending a statute. A designation names a target that can contest it. A presumption names nobody, so nobody has standing to challenge it, and the humanitarian carve-outs that survive are the ones the law forces Treasury to keep.

Deep Analysis

In plain English

OFAC is the part of the US Treasury that decides which transactions with sanctioned countries are allowed. Businesses and individuals can normally apply for a licence, a specific permission, to do something otherwise banned. From 10 September, OFAC changed its default answer to almost all new Iran-related licence requests from 'maybe, we'll look at it' to 'no, unless the law requires us to say yes or someone's safety is at risk'. Treasury said it began denying most outstanding requests immediately. An Iranian-American advocacy group, the National Iranian American Council, had already written to two senior US officials asking them not to take this kind of step, arguing that some of the exemptions being removed exist to stop ordinary Iranians and Iranian-Americans from being caught up in sanctions meant for the government.

Deep Analysis

Root Causes

Treasury set the presumption of denial under its existing authority, without further legislation, which is why the shift took effect on 10 September through a single announcement rather than a rulemaking process with a comment period.

The policy also removes a procedural burden from OFAC's own staff: under case-by-case review, each denial requires an individual justification; under a presumption of denial, staff need only justify the exceptions, inverting which decisions carry an administrative cost.

What could happen next?

Consequence
Applicants with requests already pending when the presumption of denial took effect on 10 September had their cases shifted to a default of denial without a transition period, unlike the multi-year unwind that followed the 2018 JCPOA withdrawal.

Source Landscape

This story draws on neutral-leaning sources

Primary parallel: US Iran sanctions have swung between case-by-case licensing and blanket denial before. The 2016 JCPOA implementation opened a licensing channel for civil aviation and other trade, which the 2018 US withdrawal from the deal then closed again within two years, restoring a presumption-of-denial posture similar to the one adopted on 10 September.

Counter-parallel: That 2018 reversal took roughly two years of diplomatic unwinding to implement fully. The 10 September shift moved an entire licensing category from case-by-case review to presumptive denial in a single Treasury decision, with no comparable transition period, leaving pending applicants with no notice before the default changed under them.

Consensus view: Treasury's Licensing Division said it began immediately denying most outstanding Iran-specific requests once the presumption of denial took effect on 10 September, framing the policy as consistent with the sectoral designations and wind-down orders it issued across the same week.

Counter-view: The National Iranian American Council wrote to Treasury Secretary Scott Bessent and Secretary of State Marco Rubio before this policy took effect, arguing the licence exemptions it targets were established over a decade ago specifically to prevent US sanctions from causing harmful unintended consequences for ordinary people, not to be reversed by a blanket default.

Key tension: Whether a presumption of denial, applied across the board, still leaves room for the case-by-case humanitarian and safety exceptions the policy nominally preserves, or whether the exceptions become theoretical once the default assumption runs the other way.

Different Perspectives

United States (Joint Maritime Information Center)

The JMIC, the US-led naval reporting cell, rated the Hormuz threat "severe" in its 25 October advisory, as reported by gCaptain, and warned of possible renewed mining. Eight days earlier it found no substantiation for the Guards' mine claims, while US-facilitated transits ran at about 34 a day.

United Kingdom (CPS and Counter Terrorism Policing)

The CPS charged two men under the National Security Act 2023 over the RAF Fairford incident, and Counter Terrorism Policing said it believes the foreign intelligence service involved is Iran's, LBC reported. The case now runs through the courts; both men are charged, not convicted.

Aden and Yemen's recognised government

The Houthis told people to leave Aden airport, in the government-held south, before a missile fell there on 28 October, AFP reported, and police reported a second attack that afternoon. The fight between Riyadh and the Houthis is landing on the south's main civilian airport.

Qatar (mediators)

Qatar-led mediators put new terms to Iran this week, which an Iranian official called "ideas, not a proposal". Riyadh framed the Tehran meeting as support for Qatari and Pakistani mediation, keeping Doha at the centre of the indirect channel.

Korea Shipowners' Association

The association said the ships Iran listed were sub-chartered to an overseas oil company, not owned by Sinokor, carried no South Korean crew, and that Sinokor was unaware of the warning. South Korea's shipowners are contesting whose vessels the notice covers before it takes effect.

Kuwait (foreign ministry)

Kuwait summoned Iran's ambassador, Mohammad Toutounji, and handed him a protest note over the embassy's denial that its citizen took part in the alleged plot against Interior Minister Fahad Al-Yousef. Kuwait is answering through its courts and a diplomatic protest, citing international law and the UN Charter.
