The sanctions that need no signature

The US Treasury has kept sanctioning Iran throughout the war under a pre-war memorandum, freezing nearly half a billion dollars while Trump has signed no new order of his own.

Key takeaway

US sanctions on Iran keep firing on pre-war authority; only sanctions relief needs a new signature.

The US Treasury has run a named, continuous sanctions campaign against Iran throughout the war, even as the White House has signed no new Iran measure. Treasury calls the campaign Economic Fury, and it operates under National Security Presidential Memorandum 2 (NSPM-2), a pre-war order that delegates designation power to the department rather than requiring a fresh presidential signature⁠1.

On 27 May the Office of Foreign Assets Control (OFAC), Treasury's sanctions arm, designated Iran's Persian Gulf Strait Authority for extorting Hormuz shipping tolls; on 10 June it blacklisted nine China and Hong Kong entities for arming the Islamic Revolutionary Guard Corps (IRGC)⁠2. Treasury says the campaign has frozen "nearly half a billion" dollars and disrupted "tens of billions" in regime-linked revenue⁠3. A direct query of the Federal Register returned zero new Iran filings between 29 June and 2 July⁠4.

The gap between an empty signing record and live enforcement has a mechanism. NSPM-2 delegates designation authority to OFAC through executive orders that predate the conflict, so Treasury can keep naming targets while any genuinely new instrument stalls. The one Iran action that did need a fresh signature, General Licence X, loosened sanctions rather than tightening them, and its missing escrow and reporting caps handed Chinese buyers a 60-day safe harbour. Relief requires a pen; pressure does not.

Donald Trump's public words and Washington's actions point in opposite directions. On 30 June he demanded cheap petrol on Truth Social and signed nothing; on 1 July he called the denuclearisation of Iran "moving along well"⁠5. His earlier order for a Justice Department oil-gouging probe sits in the same column: enforcement motion that does not require settling the war.

Deep Analysis

In plain English

The US Treasury has been sanctioning parts of Iran's economy continuously since before the war even started, under a standing campaign called Economic Fury. It does not need the president to sign anything new each time: officials can add names to the sanctions list on autopilot. In the past six weeks alone, Treasury sanctioned the Iranian body that tries to collect tolls from ships in the strait of Hormuz, and nine companies in China and Hong Kong accused of helping arm the IRGC, Iran's most powerful military force. Even though no new sanctions appeared in the official US government record for four straight days, that gap does not mean enforcement stopped.

Deep Analysis
Root Causes

Economic Fury runs on National Security Presidential Memorandum 2, a delegation of designation authority to Treasury that predates the war and requires no fresh presidential signature to continue. That is structurally different from General License X, the one Iran sanctions instrument that did need Scott Bessent's active signature to authorise oil sales and dollar payments .

The zero-filing gap between 29 June and 2 July does not mean enforcement paused: OFAC's designation pipeline runs independently of both the Doha talks and the Federal Register's publication cycle, so a quiet week in the public record does not mean a quiet week inside Treasury.

What could happen next?
  • Consequence

    Continued designations during the funeral pause keep economic pressure on Iran even while every diplomatic channel is closed.

  • Risk

    If Tehran reads ongoing designations as evidence Washington is not serious about a deal, it hands hardliners in the Assembly of Experts and IRGC ammunition against the negotiators.

Different Perspectives
Wang Yi

China's foreign minister and Djibouti's issued a joint communique on 21 October saying the war should not reach the Horn of Africa and stressing free navigation through Bab al-Mandeb. The text names neither Iran nor the Houthis, and Djibouti hosts China's only overseas military base, opposite the Yemeni coast.
Ministry of External Affairs

India's foreign ministry called the attacks on Saudi civilian and energy sites "unacceptable" on 22 October and said they must stop at once. An Indian died at Dammam, Indians were injured there and at Shaybah, and about 4,000 Umrah pilgrims remain stranded by one MP's count.
Iraq

Iraq closed the al-Sheeb crossing with Iran to travellers and trucks from 21 October and said other crossings would close gradually. Unlike September's closure, which ended on a staged timetable, this one has none, and Iran's interior ministry said it received no notice.

Egypt's president said on 21 October that Cairo's support would "defend Saudi territory, and does not include an attack on Yemen". Araghchi warned that Egyptian involvement would further complicate the situation, and Cairo's limit matches the one Ankara set on 8 October against attacking another state's soil.

The MoD said on 20 October that RAF Typhoons over Saudi Arabia will not strike the Houthis, but extended tanker support to Saudi operations including against Houthi targets in Yemen. The tanker line sets no limit on strikes, so British aircraft may now refuel Saudi jets on bombing runs.
Turkey
Turkey
Ankara sent the Mecca Joint Defence Agreement to parliament around 20 October, and its published text treats an attack on one party as an attack on all. Article 16 brings it into force only on the last ratification, so the 5 October invocation in Riyadh could not yet bind Turkey.
