WASHINGTON/DUBAI — The United States and Iran have reached a preliminary agreement to halt months of conflict and begin reopening the Strait of Hormuz, triggering a sharp decline in global oil prices and lifting investor confidence across international markets.
The agreement, announced Monday, marks the most significant diplomatic breakthrough since fighting escalated earlier this year and disrupted one of the world’s most critical energy corridors. Officials from both countries confirmed that the framework is designed to end active hostilities, ease maritime restrictions, and restore commercial shipping through the strategic waterway.
The Strait of Hormuz carries roughly one-fifth of global oil and liquefied natural gas shipments, making its closure a major shock to energy markets and supply chains worldwide. Since the conflict intensified, shipping routes were disrupted, oil prices surged, and governments raised concerns over inflation and economic instability.
Markets reacted immediately to news of the deal.
Brent crude prices fell about 5% to near $83 per barrel, while U.S. West Texas Intermediate crude dropped more than 5%, reaching their lowest levels in approximately three months. Analysts said the decline reflected expectations that oil exports and maritime traffic could gradually return to normal if the agreement holds.
Global equities also responded positively. European markets climbed to record highs while investors shifted toward risk assets amid hopes that reduced geopolitical tensions would ease inflation pressures and support economic growth.
According to officials involved in negotiations, the current arrangement functions as an interim framework rather than a final settlement. Major unresolved issues—including Iran’s nuclear program and the longer-term structure of sanctions relief—are expected to be addressed during follow-up negotiations under a proposed 60-day ceasefire period.
Diplomatic mediation efforts reportedly involved Pakistan, with discussions expected to continue before a formal signing ceremony anticipated later this week in Switzerland. However, Iranian officials have indicated that technical and political details still require further review before any final implementation timeline is guaranteed.
Despite the optimism, maritime operators remain cautious.
Shipping companies and insurers have signaled they will wait for clearer security assurances and confirmation of safe passage before fully resuming operations through Hormuz. Industry observers noted that reopening trade flows may take time due to operational risks, insurance concerns, and infrastructure readiness across the region.
The agreement is also expected to become a central topic during ongoing international discussions among leaders gathering for the Group of Seven summit in France, where broader questions surrounding regional stability and global economic recovery remain in focus.
For now, financial markets appear to be betting that diplomacy may finally bring an end to one of the year’s most disruptive geopolitical crises—though the durability of the agreement will depend on whether negotiations can move beyond the ceasefire and address the deeper issues that fueled the conflict.
