The announcement on June 15, 2026, of an agreement between Washington and Tehran to end the war and reopen the Strait of Hormuz to international maritime trade instantly shifted the tone of the war-focused agenda that had dominated the past three months.[i] Energy prices, which had been rising due to disruptions in the flow of crude oil from the Gulf to world markets, fell sharply following the news of the agreement, leading to a significant easing of expectations regarding global inflationary pressures.[ii]
Unlike a ceasefire with clearly defined boundaries, this arrangement focuses directly on the status of the Strait of Hormuz and the principles of safe passage. Consequently, what we are seeing is not so much the end of the war as a maritime security agreement that reshapes energy geopolitics. The effects already evident suggest that this will lead to a recalculation of interests across a broad spectrum, from the Gulf monarchies to Asian energy importers and price volatility in Europe.
Looking at the reality on the ground, the de facto closure of the Strait of Hormuz, which forced oil and LNG tankers to reroute, drove up insurance costs, and increased navigation risks, had redefined energy security through a supply shock. As a result of the escalating conflict between the U.S. and Iran, the surge in Brent crude oil prices above psychological thresholds within a matter of weeks had become one of the main factors fueling volatility in global stock markets.
At this stage, the first tangible result of the agreement is precisely the resolution of this risk premium. The fact that oil prices fell by more than 10 percent even during the temporary ceasefire, when the Strait of Hormuz was declared “open” again, demonstrates how a permanent arrangement has more quickly anchored market expectations. It is therefore not surprising that Asian markets, which are sensitive to the uninterrupted flow of energy supplies, and European economies, which are struggling with inflationary pressures, view safe maritime passage as vital as much as any peace provision.
By placing the Strait of Hormuz at the center of the agreement, Washington aims, on the one hand, to alleviate inflationary pressures domestically and, on the other, to build a Middle Eastern order that allows it to focus more comfortably on its Asia-Pacific priorities. From Iran’s perspective, the resumption of energy exports provides a critical breathing space that prevents the conflict from escalating into a sanctions package more severe than the costs of allied military strikes.
While preserving its room to maneuver regarding maritime traffic, the Tehran administration gains the opportunity to avoid appearing to the West as an actor that has completely slipped out of control. This framework is not only a technical compromise that freezes military tensions in the Gulf but also serves as a starting point for a period during which Iran will reestablish its bargaining power through energy corridors in the medium term. Every day that the Strait of Hormuz remains open will represent a strategic window of opportunity that expands Tehran’s regional negotiating leverage.
The calculations of the Gulf monarchies, however, point to a more complex picture in this new era. For Saudi Arabia, the United Arab Emirates (UAE), and Qatar, a prolonged closure of the Strait of Hormuz presents a scenario that jeopardizes both their budget revenues and their image of energy reliability. These same actors have been working for some time to reduce their dependence on the strait by utilizing alternative routes and land-based pipelines. However, the global pricing power of energy exports still relies on the continued flow of oil through the Strait of Hormuz.
The relief effectively provided by the Iran-U.S. agreement encourages Gulf capitals to maintain security cooperation channels with Washington, while also reinforcing efforts to keep tensions with Tehran below a controlled threshold. Regional competition will shift from displays of hard power toward a focus on who will guarantee the stability of energy corridors.
The decline in energy prices, while initially dampening revenue expectations for producers, particularly Russia, that rely on surplus supply, is strengthening the hand of importing economies in Europe and Asia that are catching their breath. From Moscow’s perspective, the return of oil passing through the Strait of Hormuz to the market at lower prices represents a new dynamic that makes it more difficult to replace export revenues curtailed by the war in Ukraine.
Major importers such as China, South Korea, Japan, and India, meanwhile, view the securing of maritime traffic as a critical development that alleviates cost pressures in the short term. Beijing’s long-standing framing of its “Maritime Silk Road” investments extending to the Persian Gulf in terms of maritime security makes it possible to interpret the new Hormuz-focused arrangement as one of the stabilizing pillars of its energy strategy. India, meanwhile, is expected to link this agreement to new opportunities for maritime diplomacy, both to reduce vulnerabilities in its energy supply and to enhance its geopolitical influence in the Indian Ocean.
On the European front, the decline in oil and gas prices is easing, albeit temporarily, the inflationary pressures fueled in recent years by the war in Ukraine and tensions in the Middle East. The reduced risk in the Strait of Hormuz is lowering insurance costs while also limiting the cost increases passed on to Europe through freight rates. Nevertheless, it would be incorrect to expect a fundamental shift in the continent’s perception of energy security. This is because both the process of moving away from Russian energy and the fragility in the Middle East will continue to compel European capitals to pursue more diversified supply routes in the medium and long term. Consequently, while the relief from the Strait of Hormuz offers a temporary respite, it does not carry a promise of stability that would bring an end to Europe’s strategic quest for energy geopolitical solutions.
The fact that discussions regarding security and transit fees in the maritime traffic aspect of the agreement are ongoing indicates that the future status of the Strait of Hormuz has not yet been fully institutionalized. While Iran maintains its claim to have a say in the cost of trade passing through its territorial waters and sphere of influence, the U.S. is using the rhetoric of global trade freedom to legitimize its military presence as a tool for maritime security. At the point where this line of tension directly intersects with great power competition, China and Russia also enter the picture. Although Beijing appears to advocate the principle of free passage and prioritizes the security of its trade, it is uncomfortable with the U.S. Navy’s growing permanent presence. Moscow, meanwhile, will likely intensify its legal and political arguments both to balance its cooperation with Iran and to limit the U.S. practice of expanding its maritime jurisdiction.
From Türkiye’s perspective, the reopening of the Strait of Hormuz is being closely monitored in terms of the stability of the energy supply chain and the revitalization of regional diplomatic channels. Ankara tends to view the broad energy corridor stretching from the Black Sea to the Eastern Mediterranean, and from Iraq and the Caucasus to the Strait of Hormuz, as a holistic security zone. In this new era, both consultation channels within the North Atlantic Treaty Organization (NATO) and deepening political relations with Gulf countries are positioning Türkiye to assume a role as a mediator and facilitator on energy security issues. Furthermore, the development of alternative trade routes via Iraq and the Eastern Mediterranean is viewed as complementary options that help balance the pressure on the Strait of Hormuz.
In conclusion, the Iran-U.S. agreement is characterized by a pragmatic compromise that prioritizes the restoration of energy transit routes over ending the war. The sharp drop in oil prices, the easing of tensions in global markets, and the normalization of maritime traffic as soon as the Strait of Hormuz reopened demonstrate that economic security concerns lie at the heart of this agreement. Nevertheless, ongoing disputes over transit fees, insurance costs, and maritime security indicate that the Strait of Hormuz will not remain a zone free of power struggles for long.
Regardless of whether the conflict escalates again in the coming period, it appears that the Gulf monarchies, Asian energy importers, European economies, and regional powers will all base their calculations on a Strait of Hormuz-centered energy geopolitics. If the parties fail to secure the sustainable security of this transit route through institutional mechanisms, the current lull will soon turn into a silent harbinger of a new shock.
