Iran-Oman Hormuz Agreement by August 22?

Thesis

• Time decay dominates: with only 6 days to close, a formal Iran-Oman Hormuz agreement would need to be essentially complete and scheduled already; diplomatic agreements of this sensitivity typically involve extended negotiation, domestic sign-off in Tehran, and advance signaling, none of which compresses well into a week.
• Signal vs. narrative: the only hard signal available is that the market sits at 15% with modest volume (~$12k/24h), suggesting some traders believe negotiations are live; the narrative risk is that routine Iran-Oman diplomacy (a historically warm back-channel relationship) gets over-read as an imminent deal when most such talks produce communiqués, not signed agreements.
• My independent estimate of ~10% is modestly below the market's 15%; the divergence is plausibly explained by the market pricing in late-stage negotiation rumors I cannot verify, and by a small YES-bias from traders anchored on Oman'’s mediator role rather than on the low base rate of signed agreements inside a 6-day window.

Base rate

Specific, named bilateral agreements resolving YES within a roughly one-week window are rare events; absent a publicly announced signing ceremony or leaked finalized text, such markets historically resolve YES well under 15% of the time.

What would prove this wrong

A credible report (Reuters/AP or official Iranian/Omani statements) that a signing ceremony is scheduled or that finalized text has been agreed would push this sharply higher; absence of any such announcement by ~48 hours before close pushes it toward 2-3%.
