Key takeaway

The MOU promised sanctions relief on a schedule to be agreed, which is no schedule at all.

The Office of Foreign Assets Control (OFAC), the US Treasury arm that administers sanctions, issued no Iran waiver, general licence or delisting through 18 June. Its updates that day touched Counter-Terrorism and Cuba designations only 1. The published text of the US-Iran memorandum explains the silence rather than contradicting it : full sanctions relief, including the United Nations Security Council resolutions, is tied to a "final agreement" on "a schedule to be agreed", and only oil-transaction waivers apply "immediately upon signing" 2.

That distinction matters because an OFAC licence is a mechanical instrument, not a statement. Its absence settles the question in a way a podium denial cannot. Roughly $100bn in frozen Iranian assets and a $300bn reconstruction plan are both contingent on a deal that has not been drafted 3.

Secretary of State Marco Rubio told Congress on 2 June the United States "is not discussing, nor has it offered, sanctions relief for Tehran", and he has not walked that back 4. One US official called the 14-point text a "gentleman's agreement". The structure follows the position Washington held before signing: the MOU defers relief because The Administration had not conceded it. For Iran's hardliners, the empty register is evidence the deal delivers nothing now, strengthening the Paydari and IRGC case against it.

Deep Analysis

In plain English

The United States has a powerful tool called sanctions. These are legal rules that forbid US companies and anyone using US dollars from doing business with Iran. Most of Iran's money, roughly $100 billion, has been frozen in foreign banks because of them. After the deal was signed, Iran expected Washington to start loosening these rules. But OFAC, the US Treasury sanctions bureau, issued no Iran waiver on 18 June. The deal's text explains why: the main sanctions relief comes only after a bigger, future final agreement is signed. The $100 billion stays frozen. Iran cannot access it through any existing legal channel under the MOU as written.

Deep Analysis
Root Causes

The OFAC gap has three structural roots. First, the MOU was deliberately drafted to make sanctions relief conditional on a final agreement rather than the interim framework. Republican Senate pressure from Thune and others who would not back the deal without its text made immediate relief politically acute.

Second, Rubio's 2 June congressional testimony created a public record that the US had not offered Iran sanctions relief. No such reversal was issued through 18 June, meaning OFAC action would have directly contradicted the Secretary of State's testimony.

Third, OFAC's sanctions architecture spans multiple executive orders and congressional statutes. Issuing a comprehensive Iran general licence without congressional notification would create legal exposure that Treasury was unwilling to accept without a final deal in hand.

Escalation

OFAC inaction through 18 June is the first concrete data point for Iranian hardliners arguing that the MOU produced no real benefit. If Iran's IRGC or parliament uses the sanctions gap to argue that Phase 2 is futile, the escalation risk rises significantly before talks even begin.

What could happen next?
  • Risk

    The OFAC sanctions gap gives Iran's IRGC concrete evidence to present domestically that the MOU delivered nothing material, potentially undermining Pezeshkian's political position before Phase 2 begins.

    Short term · Assessed
  • Consequence

    Iran's roughly $100 billion in frozen assets remain inaccessible under the MOU structure, preventing any significant economic recovery or reconstruction spending until a final agreement is signed.

    Medium term · Assessed
  • Precedent

    The MOU's oil-waiver-only structure sets a precedent for future Iran negotiations that economic normalisation is a Phase 3 outcome, not a Phase 2 incentive, which may complicate the next negotiating round.

Different Perspectives
International Group of P&I Clubs
International Group of P&I Clubs
The Group has kept its Hormuz war-risk exclusion in force through the entire shipping recovery, even as London hull war-risk premiums fell to about 2% of vessel value. A burning LNG carrier off Limah is now the fresh case for holding that line, with mutual pooling meaning one hit reprices the strait for every owner at once.
Jordan
Jordan
Jordan's government said no threats existed at Aqaba hours before Iranian missiles landed there, and has not addressed the IRGC's claim that Jordanian civilians and soldiers supplied targeting intelligence for the strike. Amman hosts forces it does not command and is saying as little as it can.
United States (CENTCOM)

The Pentagon named two of the seventeen American dead, 1st Lieutenant Tyler Feehan and Private Isabella Gonzales, both killed at Jordan's Muwaffaq Salti Air Base, days after its Amman embassy had warned citizens away from Aqaba's airport and seaport. Washington is naming its own cost while flagging threats it declines to attribute publicly.
Iran
Iran
Iran said on Monday it disabled two oil tankers crossing the Strait of Hormuz without its permission, asserting a right to license passage through the strait it borders. Tehran named neither vessel, and CENTCOM had already denied a comparable Iranian claim on 18 July.
Qatar
Qatar
Qatar moved from summoning Iran's deputy ambassador on 8 July to a dated written claim at the UN Security Council thirteen days later, citing Resolution 2817 and reserving its Article 51 right of self-defence. Doha is building a permanent record while still hosting CENTCOM's forward headquarters and mediating with Tehran.
CENTCOM
CENTCOM
CENTCOM confirmed a third American service member died in northern Iraq on 19 July clearing unexploded ordnance from a downed Iranian drone, and recovered unidentified remains at Muwaffaq Salti Air Base in Jordan. The Pentagon has framed its Khuzestan strikes as degrading IRGC capacity, a rationale that stretches to explain a reactor foundation with no nuclear material in it.
