The Cost of Stalemate: U.S.-Iran Confrontation, the Uranium Enrichment Deadlock, and the Global Energy Security Dilemma

On May 7, 2026, local time, a brief exchange of fire occurred between the United States and Iran in the Strait of Hormuz. The two sides offered conflicting accounts of its cause: Washington claimed it acted in self-defense, while Tehran accused the U.S. of violating the ceasefire agreement and attacking an Iranian oil tanker first. After the incident, the United States stated that the ceasefire agreement remained in effect; Iranian media, meanwhile, reported that the situation in the strait and surrounding waters had returned to normal. While the military friction was notably limited in intensity and did not trigger a sharp escalation, the patterns of U.S.-Iran strategic maneuvering it revealed, along with its cascading effects on global energy supply chains and regional structures, warrant examination from an international perspective.

The geoeconomic context of this exchange of fire cannot be overlooked. The Strait of Hormuz is one of the most critical energy chokepoints in the world: roughly 20 percent of global oil and liquefied natural gas shipments pass through it, with daily crude oil transits reaching 21 million barrels. Owing to persistent U.S.-Iran tensions, the strait had already been in a state of semi-paralysis; during the clash, no large commercial vessel traversed it for 48 consecutive hours. According to the International Energy Agency, global oil supply is expected to drop by about 3.9 million barrels per day, and inventories are declining at a record pace. This constitutes the most essential international dimension of the event: the military contest between the U.S. and Iran generates externalities that directly strike the energy lifeline of the global economic system. Most nations that depend on Middle Eastern energy imports, particularly the industrialized economies of the Asia-Pacific, are compelled to bear the external costs of this contest. Such structural asymmetry—where the belligerents shoulder the military and political costs while third parties absorb the economic ones—is in itself a symptom of an unbalanced international system.

Observed from the negotiation angle, the core divergences between the U.S. and Iran remain far from bridged. Two parallel 14-point frameworks now coexist: the American proposal focuses on Iran reopening the Strait of Hormuz in exchange for a gradual lifting of Washington’s maritime blockade, and on Iran limiting its nuclear program in return for the removal of certain sanctions; the Iranian proposal envisages a three-phase process spanning a transition from a temporary ceasefire to a full cessation of hostilities and the establishment of a new management mechanism for the Strait of Hormuz. The two frameworks differ markedly in their structural objectives and implementation pathways. On the substantive issue of uranium enrichment, the positions are even more antagonistic. The U.S. insists that Iran’s 60-percent-enriched uranium be shipped out of the country, whereas Iran refuses to transfer its enriched uranium abroad, offering only to dilute it under the supervision of the International Atomic Energy Agency. Regarding the duration of any suspension of enrichment activities, the U.S. has proposed a period of 20 years; Iran has indicated that it could accept a maximum of five. Tehran has also explicitly stated that nuclear technology and the enrichment question will not be placed on any negotiation agenda, and has hinted that enrichment could be raised to 90 percent purity if it is attacked again. In fact, the structural opposition over the duration of enrichment activities—Iran insists on a suspension while the U.S. demands a permanent cessation and the removal of highly enriched uranium—has already become the fundamental reason why the talks are struggling to advance.

It is worth emphasizing that this is not a simple bilateral affair; it is embedded in a complex regional power configuration. Israel has played a role that cannot be ignored in this round of negotiations. Israeli leaders have clearly stated that the war with Iran is not over, that Iran’s enriched uranium must be removed and its related facilities dismantled, and have even floated the operational vision of sending people in to take it out. Such an openly hardline stance imposes substantive constraints on Washington’s diplomatic space, leaving little room for any meaningful U.S. concessions at the negotiating table. Meanwhile, countries such as Pakistan and Switzerland have expressed a willingness to mediate and attempt to play an intermediary role, while some Gulf Arab states are showing flexibility on lifting the restrictions placed on U.S. forces’ use of their bases and airspace. This pattern of diverging regional positions indicates that the U.S.-Iran confrontation has already moved beyond the traditional great-power competition framework and has evolved into a more complex regional security predicament.

Viewed from the perspective of the international system, the co-existence of intermittent military friction and a protracted negotiating stalemate between the U.S. and Iran reflects a deeper dysfunction in current global security governance mechanisms. The safety of passage through the Strait of Hormuz is supposed to be collectively guaranteed by international maritime regimes. In reality, two states effectively hold the valve of a global energy artery in their hands through bilateral military standoffs and negotiations. Such a privatization of a global public good means that third countries, whether directly involved in the conflict or not, are forced to bear substantive shocks to their energy security. China’s Ministry of Foreign Affairs has publicly called for the early restoration of passage through the strait, stressing that protecting the safety of civilian vessels and crews serves the common interests of regional countries and the international community. Such a statement in itself reflects widespread international unease with the current mechanism.

In terms of economic transmission effects, the impact of the U.S.-Iran conflict on global oil markets has continued to build. The head of commodities research at Citigroup has pointed out that oil prices will experience severe volatility until a clear agreement is reached between the two sides. The pressure on physical crude supplies from the Middle East persists; even if the conflict were to end in the near term, the rebuilding of global oil and gas inventories would require at least three to six months, and the repair of Qatar’s liquefied natural gas export facilities could take years. Persistently elevated energy prices are transmitting along industrial chains, with prices of fertilizers, petrochemical products, and industrial gases such as helium all registering notable increases, substantially eroding stable expectations within the global trading system.

Taken as a whole, while the intensity of the military clash in the Strait of Hormuz remained controllable, the systemic problems it has laid bare deserve serious attention. Both the United States and Iran are employing military force as an instrument of diplomatic pressure. In this cycle of maximum pressure, limited response, negotiating deadlock, and renewed pressure, global energy security, international trade order, and regional strategic stability are compelled to endure sustained strain. And the structural opposition over uranium enrichment on the negotiating table means that even if the two sides were to reach a near-term procedural arrangement, the leap from a temporary ceasefire to a durable security arrangement would still face numerous institutional obstacles. In this contest, the real risk lies perhaps not in a one-off military action by either party, but in the way this persistent state of confrontation is systematically eroding the international community’s trust in multilateral security mechanisms, leaving the stability of global energy arteries and the regional order in a prolonged state of suspension.
