A temporary Strait of Hormuz plan under discussion with Oman would give Tehran full control over inbound shipping, according to sources

• Outbound vessels would use a route between Iran and Oman, with Oman clearing departures after notifying Iran. 
• Iran is unlikely to accept another reopening alternative.

Proposals to reopen the Strait under an Iranian-monitored regime are a familiar feature of closure episodes: the negotiating track typically runs through a regional intermediary, here Oman in its established backchannel role, and the sequencing question is whether a framework acceptable to Tehran can be reconciled with freedom-of-navigation demands from Washington and European capitals. The split that matters is outbound versus inbound: ceding Iran clearance authority over inbound traffic is precisely the point on which past proposals of this kind have stalled, since it formalizes the leverage the US and UK navies exist to dilute. Market precedent is that crude and freight rates fade reopening headlines quickly when no physical flow has actually resumed, while tanker insurance premia and the prompt spread hold elevated until laden sailings are confirmed. The peer set to watch is Gulf producer loadings and any parallel naval posture statements rather than the diplomacy itself. The tell that a plan is live rather than positioning is Omani or Iranian official confirmation; sourcing of this kind, unattributed and conditional, has historically preceded rejection as often as agreement.
