US seeks Iranian pledge to free up Strait of Hormuz

The United States is pressing for a public and written commitment from Iran to ensure the unobstructed flow of global energy supplies through the Strait of Hormuz, as diplomatic efforts resume amidst a volatile military landscape. The push for a pledge arrives as Iranian Foreign Minister Abbas Araqchi traveled to Oman on Saturday to engage in mediation efforts intended to de-escalate the conflict that has persisted since airstrikes were launched against Iran on February 28.

Washington has made the security of the waterway a central condition for any future diplomatic progress. Senior US officials, including representatives expected to lead negotiations—Vice President JD Vance, Secretary of State Marco Rubio, special envoy Steve Witkoff, and advisor Jared Kushner—have demanded that Tehran publicly confirm the strait will remain open, free of tolls, and safe for commercial transit. This waterway, which accounted for one-fifth of global oil supplies prior to the war, has effectively been under the control of Iranian forces for much of the conflict, resulting in a strategic stalemate.

Media additions

The diplomatic maneuvering follows a week of direct military confrontations. After three commercial tankers belonging to Qatar and Saudi Arabia were targeted earlier in the week, the United States responded with strikes on Iranian sites. Iran subsequently launched retaliatory attacks against US military facilities located in Gulf states. While no new attacks were reported as of Saturday, the situation remains highly fragile. US officials stated that Iran privately characterized the recent shipping attacks as the work of an errant part of their system, a move interpreted in Washington as an attempt to reduce regional tensions. Conversely, Iranian state media reported that Foreign Minister Araqchi arrived in Oman to discuss passage arrangements, even as the Iranian Fars news agency cited a source claiming that no negotiations would occur until the US retreated from its current military and political positions.

The uncertainty surrounding these talks is compounded by an ongoing dispute over the status of a previous ceasefire. US President Donald Trump stated on Friday that while he agreed to continue discussions, the ceasefire agreement itself is OVER. This declaration followed the US decision to revoke a license authorizing the sale of Iranian crude on Tuesday, a move that Tehran labeled a violation of existing commitments. Further complicating matters, the US has explicitly linked the Hormuz transit issue to a broader set of demands regarding Iran’s nuclear program. Washington officials indicated that there will be no comprehensive deal unless Iran surrenders what the administration calls nuclear dust, identified as highly enriched uranium buried beneath the debris of targeted nuclear facilities.

Internal Iranian messaging adds further friction to the negotiations. Following the death of Supreme Leader Ayatollah Ali Khamenei on February 28, a successor, Ayatollah Mojtaba Khamenei, issued a statement on Saturday pledging vengeance for his father and other martyrs. The rhetoric has been met with explicit threats from the US side. President Trump warned on Truth Social that the US military is prepared to launch thousands of missiles against Iran if the Iranian government acts on threats to target his life, following reports that intelligence had identified a plot to assassinate the US leader.

The conflict, now entering its fifth month, continues to impact the global economy. Although oil prices had experienced a decline in recent weeks, the renewed hostilities triggered the largest weekly rise in crude prices in eight weeks, creating significant pressure on energy markets ahead of US congressional elections in November. At least 17 people were killed and 115 wounded in US strikes across six Iranian cities between Wednesday and Thursday, according to the Iranian Health Ministry.

What to watch next

• Negotiation Outcome: The success of the discussions in Oman is viewed by the US as a litmus test. Washington officials maintain that if Iran cannot guarantee safe commercial navigation, it will be impossible to move on to the more complex issue of the nuclear programme.
• Diplomatic Window: While President Trump has permitted his team to engage in talks, senior officials have warned that the time allotted for a diplomatic solution is limited.
• Security Posture: With the ceasefire declared void by the US, both sides are maintaining a heightened military state. Observers are monitoring whether the verbal exchange between the new Supreme Leader and the US president will escalate into further direct kinetic action.
