Global energy markets reacted with relief when news emerged that the Strait of Hormuz was set to reopen under a US–Iran understanding, a sign that traders had already priced in the extent of the damage inflicted on supply chains over the preceding months of conflict. Brent crude fell sharply, equities rallied, and shipping insurers began recalculating risk premiums almost immediately.
However, beneath the financial repricing lay a political adjustment, a recognition that Iran, despite enduring sustained military pressure from the United States and Israel, had succeeded in converting battlefield vulnerability into negotiating leverage. The agreement, described by Donald Trump as “now complete,” due to be signed in Switzerland, marked not only a pause in hostilities. Instead, it is an implicit acknowledgement that coercive force had failed to deliver the strategic outcome Washington and Jerusalem had initially sought.
The framework of the deal reflected that recalibration. Mediated by Qatar and Pakistan after weeks of indirect contacts, it envisages a phased reopening of the Strait of Hormuz, gradual mine clearance over 30 days and a temporary suspension of Iranian tolls on shipping for 60 days. In parallel, the United States would lift its naval blockade on Iranian ports and issue a limited waiver allowing Tehran to resume oil exports during the ceasefire window.
Sanctions relief, including access to frozen overseas assets, is explicitly conditional on progress in subsequent nuclear negotiations. Preparatory talks in Doha are intended to precede formal discussions on a longer-term arrangement covering regional security and Iran’s nuclear programme, with the International Atomic Energy Agency expected to play a supervisory role in any uranium dilution mechanism.
Financial markets interpreted the announcement as an unwinding of a supply shock that had reverberated through energy-importing economies for over three months. The disruption had been severe: shipping costs surged, insurance premiums for tankers operating in the Gulf multiplied, and temporary rerouting added strain to fragile global logistics networks.
The reopening of the Strait, therefore, carries significance far beyond oil pricing. It restores a critical artery for the trade in liquefied natural gas, fertiliser and petrochemicals. However, the greater surprise for policymakers has not been the economic volatility, but the fact that Iran retained sufficient coercive capacity under heavy attack to impose such systemic costs.
When the conflict escalated in late February, following coordinated US and Israeli strikes, expectations in Western capitals were shaped by a model of overwhelming asymmetry. The campaign combined airpower, precision missiles and targeted killings aimed at Iran’s senior military and political leadership, including the elimination of key command figures.
Large parts of Iran’s air defences and missile infrastructure were degraded. Nuclear facilities were repeatedly struck. Early assessments suggested that sustained pressure could either compel the regime to capitulate or at least deprive Tehran of its ability to retaliate. That assumption proved wrong because it underestimated Iran’s capacity to operate within severe constraints.
Iran’s response drew on a strategic tradition that treats vulnerability as a domain to be manipulated. Rather than attempting symmetrical escalation, Tehran focused on preserving a residual capacity for retaliation while widening the costs imposed on its adversaries.
Missile and drone strikes on regional targets demonstrated that its deterrent capability remained operational. More importantly, attacks on energy infrastructure across the Gulf and intermittent disruptions to shipping routes introduced a second-order shock that extended well beyond the immediate theatre of war. The closure of the Strait of Hormuz, in particular, functioned as a strategic lever against economies far more dependent on uninterrupted maritime energy flows than Iran itself.
This approach aligns with what analysts of asymmetric warfare describe as the manipulation of the “balance of vulnerability,” in which weaker actors offset conventional vulnerabilities by identifying and exploiting the structural dependencies of stronger opponents. In this conflict, those dependencies included not only physical infrastructure but also political constraints.
The United States and Israel faced finite stockpiles of advanced munitions, high costs of sustained air operations and the political sensitivity of prolonged regional escalation. Iran, by contrast, was able to absorb substantial damage while calibrating its responses to maximise disruption per unit of military expenditure. The result was not battlefield parity, but strategic friction that accumulated against the intervening powers over time.
That friction was amplified by the regionalisation of the conflict. Iranian-aligned forces, particularly in Yemen and Lebanon, increased pressure on maritime and border corridors, introducing additional layers of insecurity into global shipping routes. Even when their actions were not centrally coordinated, they contributed to a broader perception that the conflict risked spilling across multiple chokepoints of the global economy.
This multidimensional pressure forced Western and Gulf states to allocate disproportionate resources to defence, interception and deterrence, accelerating the consumption of expensive, difficult-to-replace interceptors and precision-guided systems. Over time, this attrition of high-end munitions became itself a strategic constraint on escalation.
At the same time, Iran’s closure of the Strait of Hormuz demonstrated how a geographically concentrated vulnerability can be leveraged into global leverage. Although Tehran relies on the waterway for its own exports, its ability to disrupt flows through mining and the harassment of commercial shipping has asymmetric consequences for import-dependent economies in Europe and Asia.
The resulting spike in energy prices created political pressure in multiple capitals, narrowing the policy space for sustained military escalation by the United States and its partners. Energy markets, already sensitive to supply shocks, became an indirect transmission channel through which battlefield dynamics fed back into domestic political debates in Washington and elsewhere.
Domestic political considerations further constrained the durability of Western military escalation. In the United States, rising fuel prices and concerns about a widening conflict placed pressure on an administration already facing electoral scrutiny.
In Israel, the costs of multi-front engagement, both in terms of security expenditure and civilian disruption, intensified debate over strategic priorities. Gulf states, meanwhile, confronted the paradox that closer alignment with US objectives exposed them to retaliatory risk without guaranteeing stability. Iran’s strategy, in this sense, did not require a decisive military victory; it required only that the costs of continued pressure exceed the benefits for its adversaries.
Parallel to the kinetic dimension of the conflict, Iran retained a significant bargaining instrument in its nuclear programme. Despite repeated strikes on enrichment facilities, Tehran preserved a stockpile of enriched uranium, including material approaching weapons-grade thresholds, according to figures circulated in diplomatic briefings.
While Iran has consistently denied any intent to develop nuclear weapons, the existence of this stockpile has provided it with leverage in negotiations over verification, dilution and potential sanctions relief. The current framework anticipates phased oversight by international inspectors, but the sequencing of compliance and concessions remains deliberately unresolved, reflecting mutual distrust rather than technical clarity.
Iran’s leverage has also been shaped by its network of aligned non-state actors, often described collectively as its “axis of resistance.” Groups operating in Lebanon, Yemen and Iraq have, at various points, increased pressure on Israel and disrupted maritime traffic through adjacent waterways, most notably the Bab al-Mandab Strait.
While the degree of central coordination remains contested, the cumulative effect has been to widen the geographical scope of the conflict and complicate containment strategies. For Western planners, the challenge has been not only confronting Iran directly but managing a distributed set of actors capable of generating instability across multiple nodes of the global trade system.
By the time ceasefire negotiations gained traction, the strategic landscape had shifted from one of anticipated rapid coercion to protracted stalemate. Iran had not achieved military parity, nor had it neutralised its adversaries’ capabilities. However, it succeeded in preventing the decisive outcome initially envisaged by US and Israeli planners, while imposing sufficient economic and political costs to force a diplomatic off-ramp.
The reopening of the Strait of Hormuz, therefore, is an admission that neither side could sustain escalation indefinitely without unacceptable systemic risk.
Looking ahead, the likely trajectory is one of constrained de-escalation accompanied by continued strategic competition. Iran is expected to prioritise rebuilding missile and drone capabilities while preserving its capacity to threaten maritime chokepoints.
Western powers, meanwhile, will focus on reinforcing supply chain resilience and replenishing depleted stockpiles of advanced munitions. The underlying structural reality, however, remains unchanged: a militarily disadvantaged state has demonstrated that, in an interconnected global system, the ability to impose selective disruption on critical nodes can translate into disproportionate negotiating power.
In that sense, the most significant outcome of the conflict may not be the temporary restoration of oil flows, but the confirmation that vulnerability has become a strategic currency.
