US and Iran Establish Mechanism to Keep Strait of Hormuz Open Following Provisional Peace Deal

The United States and Iran have established a mechanism to keep the Strait of Hormuz open for navigation following a provisional peace deal concluded this week, according to U.S. Vice President JD Vance. The historic agreement comes after the waterway was effectively blockaded since the outbreak of war between the two countries in late February 2026. Vance, who arrived in Switzerland on Sunday for high-level talks with the Iranian delegation in the resort town of Burgenstock, expressed confidence in the progress made, stating that the mechanism will ensure the critical shipping route remains navigable despite ongoing hostilities.

Already, approximately 15 million barrels of oil have been transported through the Strait of Hormuz under the new arrangement, contributing to declining oil prices. Vance indicated that prices are expected to continue falling due to the increased oil flow. The reopening of the waterway presents a significant opportunity for U.S. refiners to purchase Iranian crude again, marking a notable shift in trade relations between the two nations. However, the pace of the full reopening remains unclear, with continued military operations in Lebanon and the need to clear sea mines from the Strait presenting ongoing challenges.

Beyond the immediate focus on keeping the waterway open, the U.S.-Iran agreement includes provisions for establishing a regional ceasefire mechanism and managing future conflicts. Vance emphasized that Washington is working with allies including Israel and Gulf Arab states to ensure the ceasefire holds as inevitable regional conflicts arise. He characterized the negotiations as laying "a foundation for what could be a truly transformed Middle East," suggesting broader implications for regional stability and U.S. diplomatic strategy in the region.
