Hormuz Becomes the Key to a Phased US-Iran Deal


09/25/2026



The emerging discussions between the United States and Iran over reopening the Strait of Hormuz point to a negotiation built around sequencing rather than a single comprehensive settlement. Instead of requiring either side to surrender its most important bargaining tool at the outset, a phased arrangement could allow Washington and Tehran to exchange concessions gradually, reducing the risk that either government appears to have conceded too much without receiving something in return.
 
The importance of such an approach is rooted in the unusual leverage held by both sides. Washington has used economic and military pressure to restrict Iran's ability to conduct trade and generate revenue, while Tehran has retained the ability to disrupt one of the world's most important energy routes. Recent reporting indicates that Iranian officials have signalled a willingness to reopen Hormuz if Washington eases military pressure and lifts its blockade, while US officials have continued to indicate that negotiations remain possible under conditions acceptable to Washington.
 
The result is a diplomatic contest in which neither side wants to make the first major concession. That makes the proposed sequencing of measures more important than the headline promise of a deal.
 
Why Hormuz Has Become the Central Bargaining Tool
 
The Strait of Hormuz matters because it is not merely a regional waterway. It is a major channel for international energy trade, connecting the Persian Gulf with the Gulf of Oman and the Arabian Sea. Before the current disruption, roughly one fifth of global petroleum liquids consumption moved through the strait, while alternatives through pipelines could replace only part of those flows.
 
The disruption has demonstrated how quickly problems in Hormuz can spread beyond the Gulf. The United States Energy Information Administration recorded a sharp decline in oil flows through the strait during the second quarter of 2026, with average flows falling to 4.9 million barrels per day from 14.9 million barrels per day in the previous quarter. The disruption contributed to higher and more volatile international oil prices and forced buyers to seek alternative supplies.
 
That gives Tehran a bargaining instrument that extends well beyond its immediate confrontation with Washington. Keeping the waterway restricted affects energy exporters, importers, shipping companies and governments concerned about inflation. Reopening it, therefore, can produce benefits for several parties at once.
 
For Washington, securing reliable navigation through Hormuz would reduce pressure on global energy markets and remove one of the most dangerous points of friction in the conflict. For Tehran, reopening the waterway could become valuable if it is directly exchanged for relief from the economic restrictions that are putting pressure on the Iranian economy.
 
Why Washington Wants Pressure to Produce Concessions
 
The American strategy has relied heavily on economic pressure because sanctions and restrictions can impose costs without requiring an immediate expansion of military operations. The latest negotiations suggest that Washington sees the pressure campaign as leverage that can potentially force Tehran toward concessions.
 
That strategy, however, creates a basic diplomatic dilemma. If Washington removes too much pressure before obtaining concrete commitments from Iran, it risks losing the leverage that brought Tehran to the negotiating table. If it refuses to ease pressure until Iran completely reopens Hormuz, Tehran has little reason to surrender its own bargaining advantage.
 
This explains why a phased arrangement is attractive from the American perspective. A first-stage agreement could establish measurable actions by both sides rather than relying on broad political promises. Washington could link specific forms of economic relief to verified improvements in maritime access, while maintaining the ability to restore pressure if commitments are not fulfilled.
 
Such an approach would also give the United States greater control over the pace of sanctions relief. Rather than removing restrictions in one move, Washington could make relief conditional, reversible and connected to clearly defined obligations.
 
Why Iran Wants the Sequence Reversed
 
Iran's position is driven by a different calculation. Tehran needs economic relief, but it also has an interest in demonstrating that pressure alone cannot force it to surrender strategically important positions. Iranian officials have indicated that the country could reopen Hormuz if the United States reduces military pressure and lifts the blockade, suggesting that economic and security relief is being treated as a prerequisite for wider concessions.
 
This explains the importance of sequencing. Tehran wants evidence that Washington is genuinely moving toward de-escalation before giving up its strongest immediate leverage. From the Iranian perspective, reopening Hormuz first could leave the country with fewer tools to compel the United States to deliver promised relief later.
 
The concern is not necessarily limited to whether Washington makes a formal promise. The durability of that promise matters. Previous attempts at accommodation have demonstrated the difficulty of maintaining agreements when the political and strategic calculations of both governments change.
 
A phased agreement could therefore allow Iran to test whether economic relief is real and sustainable before moving toward more substantial commitments. That would make implementation, verification and timing as important as the initial political agreement.
 
The Economic Stakes Extend Beyond Iran
 
The importance of reopening Hormuz is also evident in the effects that disruption has had on international energy markets. The Energy Information Administration reported that oil prices experienced significant volatility during the disruption, while Middle Eastern producers reduced output as export routes became constrained. It also found that US petroleum exports reached a record level in April as international buyers sought alternative supplies.
 
Those developments underline an important feature of the negotiations: the United States and Iran are not the only actors affected by their decisions. Gulf producers, Asian energy importers, European economies and international shipping companies all have an interest in restoring predictable maritime trade.
 
Gulf governments have particularly strong reasons to support de-escalation while resisting any arrangement that leaves Hormuz vulnerable to becoming a recurring instrument of political pressure. Their position reflects the wider regional concern that energy infrastructure and shipping routes should not remain permanently exposed to the outcome of US-Iran negotiations.
 
The United States has also begun considering longer-term ways of reducing dependence on Hormuz. Discussions about investment in alternative energy transportation infrastructure indicate that Washington and its regional partners are examining ways to reduce the strategic impact of future disruptions rather than relying exclusively on diplomatic or military responses.
 
The Hardest Issue Is Making the Deal Durable
 
The immediate challenge for the negotiators is therefore not simply reaching an agreement. It is designing one that survives the first disagreement.
 
A temporary reopening of Hormuz could provide immediate economic relief, but it would not necessarily resolve the broader dispute between Washington and Tehran. Similarly, lifting some economic restrictions could improve Iran's position without addressing the security concerns that prompted American pressure in the first place.
 
A durable arrangement would require clearly defined stages, reciprocal commitments and mechanisms for verifying compliance. Each step would need to create enough confidence for the next step to become politically possible. The sequence could begin with limited measures involving maritime access and economic relief before expanding into more difficult questions surrounding sanctions, security guarantees and the broader future of US-Iran relations.
 
The current diplomacy therefore represents a test of whether leverage can be converted into compromise. Washington's economic pressure and Tehran's control over access to Hormuz have created a form of mutual dependence: each side possesses something the other urgently wants, but neither can obtain it without addressing the other's demands.
 
That is why the proposed phased approach matters. It offers a possible way around the central problem of the negotiations by replacing the question of who gives up leverage first with a process in which concessions can be exchanged step by step.
 
The Strait of Hormuz has consequently become more than a military or energy issue. It is now the mechanism through which Washington and Tehran are attempting to determine whether pressure, economic necessity and diplomatic engagement can be converted into a controlled exit from confrontation.
