Reports cited by the final assessment
- 鲁比奥向阿曼重申美国对霍尔木兹海峡航行自由的承诺
U.S. Secretary of State Marco Rubio has reaffirmed to Oman the United States' commitment to ensuring freedom of navigation in the Strait of Hormuz. The statement, reported by financial news outlet Jin10, underscores Washington's ongoing strategic focus on maintaining open maritime passage through the critical waterway, which is a vital chokepoint for global oil shipments. The communication with Oman, a key regional partner that shares maritime borders with the strait, signals continued U.S. diplomatic engagement on Gulf security issues. No further details on the context or timing of the reaffirmation were provided in the brief report.
Final result
The deadline has passed with no agreement announced; the U.S. reaffirmed its commitment to freedom of navigation, but this does not alter the fact that the agreement failed to materialize.
Final result
Agreement reachedClosed
This period falls after the September 14 deadline, and the fact that no agreement was announced is now settled. The sole new report covers U.S. Secretary of State Rubio reaffirming the commitment to freedom of navigation in the Strait of Hormuz to Oman. This diplomatic move, occurring the day after the deadline, indirectly confirms ongoing tensions in the waterway but is unrelated to a bilateral Oman-Iran agreement. The baseline likelihood has dropped to zero, confirming the market's view that the agreement did not happen.
Key developments
- The September 14 deadline passed without any diplomatic agreement announced between Oman and Iran on Strait of Hormuz shipping management.
- U.S. Secretary of State Rubio reaffirmed the U.S. commitment to freedom of navigation in the Strait of Hormuz to Oman after the deadline.
How we read it
The current period is entirely after the September 14 deadline. The previous period already confirmed the scheduled meeting was cancelled and no agreement was announced; this judgment faces no challenge from any new evidence.
The only new report covers U.S.-Oman diplomatic communication on freedom of navigation, which involves neither Iran nor any bilateral agreement, and thus provides no evidence supporting an agreement.
Earlier updates
- — Iran unilaterally claims a deal is 'days away,' but Oman has not confirmed, and the market sees a very low probability.; During this period, Iran intensively signaled through multiple channels that a deal with Oman to manage shipping through the Strait of Hormuz is imminent, just 'days away,' and revealed plans for a new shipping corridor under Iranian control. However, all reports originate from unilateral Iranian statements. As of the period's end, there has been no confirmation from Oman or any independent third-party source. Against a backdrop of escalating maritime conflict between the U.S. and Iran, including U.S. strikes on Iranian tankers, Iran's move likely aims to shape the narrative and seize diplomatic initiative. The public baseline reference price shows the probability of this event remains at an extremely low 1.85%, indicating that market participants are highly skeptical of Iran's unilateral claims and do not view them as a reliable signal of an imminent agreement.
- — The diplomatic meeting between Iran and Gulf states scheduled in Oman on the deadline day was postponed or cancelled; no agreement was announced.; Multiple news reports this period cross-confirmed that the diplomatic meeting between Iran and Gulf Arab states, originally scheduled for Monday, September 14, in Oman, was postponed or cancelled. This meeting was seen as a key diplomatic venue for discussing Strait of Hormuz shipping issues. Its cancellation directly implies that no diplomatic agreement was announced between Oman and Iran before the deadline. The postponement was attributed to the deteriorating regional security situation following drone attacks on Saudi oil pipelines. Iran's earlier unilateral claim that a deal was 'days away' received no subsequent confirmation. The baseline likelihood dropped further from 1.85% to 0.1%, reflecting market confirmation that no agreement was reached.
- — The deadline has passed with no agreement announced; the U.S. reaffirmed its commitment to freedom of navigation, but this does not alter the fact that the agreement failed to materialize.; This period falls after the September 14 deadline, and the fact that no agreement was announced is now settled. The sole new report covers U.S. Secretary of State Rubio reaffirming the commitment to freedom of navigation in the Strait of Hormuz to Oman. This diplomatic move, occurring the day after the deadline, indirectly confirms ongoing tensions in the waterway but is unrelated to a bilateral Oman-Iran agreement. The baseline likelihood has dropped to zero, confirming the market's view that the agreement did not happen.
