Weapons, Money & Ships: How the New Iran Deal Stands Apart

## Introduction

## Nuclear Restrictions in the New Deal

The JCPOA capped Iran's nuclear material at 300 kg and limited uranium enrichment to 3.67% for 15 years—insufficient for a weapon but adequate for civilian power generation. It also granted the International Atomic Energy Agency (IAEA) unfettered access to verify compliance. After the United States withdrew in 2018, Iran’s stock rose to roughly 440 kg of uranium enriched to 60%, a level quickly convertible to weapons‑grade 90% enrichment. The new MoU repeats the language that "Iran reaffirms it shall not procure or develop nuclear weapons," yet it provides no explicit enrichment ceiling or stock‑pile size. It merely states that both parties will "discuss the issue of enrichment" and "resolve the disposition of stockpiled enriched material" under a mutually agreed mechanism, leaving the specifics for future talks. Compared with the JCPOA, the new text is considerably less detailed, but it does signal an intent to destroy the remaining enriched stock, as U.S. officials have indicated.

## Economic and Financial Dimensions

Under the JCPOA, most sanctions were lifted in exchange for Iran’s nuclear commitments, unlocking oil revenues, foreign investment, and a revitalized banking sector. After the U.S. exit, comprehensive sanctions resurfaced, choking Iran’s economy and preventing international firms from doing business there. The new MoU promises the removal of "remaining nuclear material" from Iran, which could pave the way for a gradual easing of sanctions. However, the document lacks a concrete timeline or measurable criteria for lifting restrictions, prompting uncertainty about the depth of economic relief. U.S. officials have hinted that the agreement could allow the re‑opening of financial channels for trade, especially in the shipping and energy sectors, potentially restoring cash flow to Tehran and stabilizing regional markets.

## Impact on the Strait of Hormuz and Maritime Security

The Strait of Hormuz is a chokepoint through which roughly 20% of global oil passes. During the February 2026 conflict, the waterway faced repeated threats, including Iranian statements about closing the strait and attacks on commercial vessels. The MoU pledges to create a "safe environment" for navigation through a yet‑to‑be‑defined mechanism aimed at reducing threats. While the text does not outline specifics, U.S. spokespeople suggest that removing Iran’s nuclear stockpile could lower Tehran’s perceived need to leverage the strait as a bargaining chip. If the promised security arrangements are implemented, full commercial traffic could resume, benefiting world energy markets and reducing the risk of further naval escalation.

## Comprehensive Comparison with the JCPOA

In terms of transparency, the JCPOA was far stricter: it set quantitative limits, detailed verification protocols, and granted the IAEA broad inspection rights. The new MoU relies on vague assurances and future negotiations, making its enforcement uncertain. Regarding sanctions, the JCPOA offered a clear, step‑by‑step relief schedule tied to compliance, whereas the current deal provides only a general promise of "gradual easing" contingent on the destruction of enriched material. Finally, the JCPOA contained no provisions related to maritime security; the new agreement explicitly adds a geopolitical dimension by addressing the safety of the Strait of Hormuz. These differences suggest that the Trump‑Iran deal attempts to broaden the agenda beyond nuclear issues, yet it lacks the concrete mechanisms that gave the JCPOA its credibility.
