The United States and Iran announced a preliminary agreement on June 15, 2026, to keep the Strait of Hormuz open and toll-free [1, 2].
This agreement is critical because the Strait of Hormuz is a primary artery for global energy shipments. Restoring commercial shipping in the narrow waterway between Iran and Oman is intended to de-escalate regional tensions and provide a foundation for broader negotiations [1, 5].
A U.S. State Department spokesperson said the agreement will keep the waterway toll-free for a period of 60 days [1]. This measure is designed to ease shipping constraints and quickly restore the flow of goods [1]. However, some reports indicate that the exact terms of the reopening remain classified [2].
The deal is outlined in a memorandum consisting of 14 paragraphs [3]. A White House press secretary said the document includes a $300 billion commitment from the United States to Iran [3].
Despite the agreement, there are contradictions regarding the transparency and implementation of the deal. While some sources say the 60-day toll-free period is a disclosed fact [1], other reports state the terms of the memorandum remain secret [4]. Additionally, there is disagreement over how quickly oil shipments will resume. Some analysts suggest it could take weeks or months for oil to fully flow despite the deal [6], while others believe the toll-free period will facilitate a rapid restoration of shipping [1].
A senior U.S. official said the preliminary deal calls for the immediate reopening of the Strait of Hormuz, though the exact terms remain classified [2].
“The agreement will keep the Strait of Hormuz toll‑free for a period of 60 days, easing shipping constraints.”
The short-term nature of the 60-day window suggests this is a confidence-building measure rather than a permanent resolution. By linking the reopening of a critical maritime chokepoint to a massive financial commitment and a limited timeframe, both nations are testing the viability of a broader diplomatic thaw without committing to a long-term treaty.
