Iranian and Omani negotiators have finalized a maritime draft agreement that now sits on Ayatollah Ali Khamenei's desk awaiting final approval. The deal centers on de-escalating tensions in the Strait of Hormuz, one of the world's most critical shipping lanes. Oman has shepherded these talks as a neutral mediator, pushing both sides toward maritime security arrangements.

The agreement signals genuine diplomatic momentum. Markets have already priced in optimism around a broader US-Iran nuclear accord, betting that Khamenei's approval could unlock larger regional thaws. But that's still conditional. The Supreme Leader holds veto power, and his decision will essentially determine whether this becomes a genuine breakthrough or another stalled negotiation.

What matters now is timing and messaging. Any public statement from Khamenei will ripple through oil markets and geopolitical risk premiums. A thumbs-up accelerates talks on the nuclear file. Silence or pushback sends negotiators back to square one. Watch his rhetoric closely over the coming weeks.
