U.S. President Donald Trump announced that the United States and Iran have reached a preliminary peace agreement, marking a major diplomatic shift in a conflict that has disrupted global energy flows, reshaped regional alliances, and driven volatility across financial markets. The deal, which includes plans to reopen the Strait of Hormuz, is set to be formalized through a memorandum of understanding scheduled for signing on Friday in Switzerland, according to officials involved in the process.
The announcement came after months of escalating tensions that had effectively disrupted maritime traffic through the Strait of Hormuz, a critical chokepoint through which roughly one-fifth of the world’s oil and liquefied natural gas supplies normally pass. Trump declared on his social media platform that the agreement marked the completion of a deal with the Islamic Republic of Iran, framing it as a turning point that would restore movement through one of the world’s most strategically sensitive waterways.
Under the framework, the Strait of Hormuz would be reopened, and restrictions on shipping would be lifted, allowing commercial vessels to resume transit after a period in which the route had been largely shut due to hostilities. The agreement also outlines a halt to military operations and a phased approach to unresolved issues, including Iran’s nuclear program, which is expected to be addressed in subsequent negotiations rather than in the initial accord.
Iranian officials confirmed elements of the arrangement, describing it as a framework for ending active conflict and establishing a ceasefire period during which broader issues would be negotiated. Among those unresolved matters is the future of Iran’s nuclear program, which remains a central point of contention and will be revisited in later talks under the terms of the deal.
The announcement immediately reverberated through global financial markets, with investors reacting to the prospect of reduced geopolitical risk and restored energy flows. In Asia, Japan’s Nikkei 225 Index surged to a record high, rising as much as 5.3% to 69,527.88, as traders responded to easing concerns over oil supply disruptions. Government bond yields in Japan fell sharply, reflecting expectations of lower inflation pressures tied to declining energy costs.
Japanese markets were particularly sensitive to developments in the Middle East due to the country’s heavy reliance on the region for energy imports. Approximately 95% of Japan’s oil imports originate from the Middle East, and the prolonged closure of the Strait of Hormuz had left multiple Japan-linked vessels stranded, according to industry sources. Shipping firms in Japan indicated they were awaiting further clarity on mine clearance and security assurances before fully resuming transit through the waterway.
Currency markets also reflected shifting sentiment, with the Japanese yen strengthening modestly against the U.S. dollar. Across broader Asian markets, equities and currencies rallied as the agreement signaled a potential reduction in global risk exposure. The MSCI index of emerging Asian equities climbed to its highest level in more than a week, led by strong gains in South Korea, Taiwan, and Southeast Asia, while stocks in multiple regional markets recorded notable advances.
Energy markets responded with an immediate and sharp decline in oil prices. Brent crude futures fell more than 4%, reaching their lowest level since early March, while U.S. West Texas Intermediate also dropped over 5%. The declines extended losses from earlier sessions, reflecting expectations that the reopening of the Strait of Hormuz would restore supply stability to global energy trade and ease price pressures that had persisted throughout the conflict period.
Market analysts described the reaction as a broad shift toward risk appetite, with capital moving into equities and higher-yielding currencies while the U.S. dollar softened. The easing of energy supply fears was identified as a key driver of sentiment across global markets, particularly in Asia, where trade and manufacturing economies are highly sensitive to oil price fluctuations.
The agreement also drew reactions from world leaders, who emphasized both cautious optimism and the need for implementation. French President Emmanuel Macron welcomed the deal and called for full compliance by all parties, while British Prime Minister Keir Starmer stressed the importance of restoring freedom of navigation through the Strait of Hormuz and reiterated that Iran must not develop nuclear weapons. German Chancellor Friedrich Merz said the agreement could support global economic stability if fully implemented, and Japanese Prime Minister Sanae Takaichi emphasized the importance of ensuring safe maritime passage for energy shipments.
Despite the announcement, key uncertainties remain. The fate of Iran’s nuclear program has been explicitly deferred to later negotiations, and the precise mechanisms for sanctions relief and verification have not yet been fully disclosed. Officials involved in the discussions indicated that more detailed provisions are expected to emerge during a 60-day ceasefire period, during which broader diplomatic arrangements will be explored.
The geopolitical context remains complex, with reports of continued regional tensions even as the agreement was reached. An Israeli strike on Lebanon occurred shortly before the announcement, underscoring ongoing instability in parts of the region. While some international actors welcomed the framework as a step toward de-escalation, others cautioned that unresolved security issues could still affect implementation.
In Washington, Trump framed the deal as a decisive step toward ending the blockade of Iranian ports and restoring maritime commerce, stating that shipping activity would resume and energy flows would normalize. The agreement follows earlier efforts by his administration to reshape the terms of engagement with Iran, reversing and revisiting prior diplomatic frameworks and sanctions regimes.
As the global response continues to unfold, attention is now shifting toward the upcoming formal signing of the memorandum and the subsequent phase of negotiations. With oil markets stabilizing, shipping routes poised for reopening, and nuclear discussions deferred, the agreement marks a pivotal but incomplete step in a conflict whose broader resolution remains dependent on future diplomatic outcomes.
