Crude prices fell sharply Wednesday after Iran and Oman advanced plans for a temporary shipping corridor through the Strait of Hormuz, raising expectations that constrained Middle East oil flows could begin to recover.

MONTREAL (OilMonster): Global oil prices fell to their lowest levels in more than two weeks on Wednesday as negotiations between Iran and Oman revived hopes for increased shipping through the Strait of Hormuz, one of the world's most important energy transit routes.
Brent crude futures were down $2.73, or 3.08%, at $85.85 per barrel by 10:12 GMT. U.S. West Texas Intermediate crude was down $2.21, or 2.68%, at $80.15 per barrel. Both benchmarks earlier touched their lowest levels since August 10.
Brent crude fell more than 3% during Wednesday trading.
Iran and Oman are discussing a temporary navigational corridor through the Strait of Hormuz.
The proposed framework also includes a joint mine-clearing project.
Shipping through Hormuz remains well below recent averages despite the diplomatic progress.
A permanent agreement has not yet been reached, leaving significant geopolitical and supply risks in place.
The latest market move followed talks between Iranian Foreign Minister Abbas Araghchi and Omani Foreign Minister Badr al-Busaidi over a phased approach to restoring safer commercial navigation through the Strait.
Under the proposed framework, the two countries would establish a joint temporary navigational corridor and cooperate on clearing mines from the waterway. Technical negotiations are expected to continue on a permanent corridor, future traffic management, information sharing and maritime security arrangements.
The distinction is important for oil markets. Iran and Oman have discussed a pathway toward restoring navigation, but they have not announced a full reopening of the Strait.
The waterway carried roughly one-fifth of global oil and liquefied natural gas shipments before the conflict involving Iran, the United States and Israel sharply disrupted regional maritime traffic earlier this year.
The prospect of even a partial improvement in tanker movements prompted traders to reduce some of the geopolitical risk premium that has supported crude prices during the disruption.
Market attention has increasingly shifted from the possibility of prolonged restrictions toward the possibility that negotiated shipping arrangements could restore part of the lost traffic.
That change in expectations was enough to send both Brent and WTI sharply lower Wednesday, although physical shipping data continue to show a much more restricted picture.
Only five commodity vessels passed through the Strait on Tuesday, according to preliminary Kpler data cited by Reuters. That was below a 10-day average of 15 vessels and remained far below normal pre-conflict traffic.
Oil producers have already been adapting their export logistics to the disruption.
Two very large crude carriers carrying a combined 4 million barrels of Saudi crude were heading to China after being loaded through ship-to-ship transfers off Oman, according to shipping data reported Wednesday.
Saudi Aramco has also been offering additional September cargoes using transfer points outside the Strait, including locations near Fujairah in the United Arab Emirates and Sohar in Oman.
These alternative arrangements have helped maintain some Gulf export flows, but they do not replace normal unrestricted tanker traffic through Hormuz.
The diplomatic movement comes at the same time that Washington is intensifying economic pressure on Tehran.
The U.S. Treasury announced a new sanctions campaign this week targeting Iranian petroleum interests, trading networks, companies and vessels involved in moving Iranian crude and petroleum products. The measures include companies and tankers operating across Asia, Europe and the Middle East.
Security conditions also remain uncertain.
Iran recently identified dozens of vessels it considers non-compliant with its rules for crossing the Strait and warned that listed ships could face detention, fines or cargo confiscation. Some oil companies and refiners are consequently reviewing their exposure to vessels named by Tehran.
Wednesday's price reaction shows how sensitive the crude market remains to developments surrounding the Strait of Hormuz.
A workable corridor that allows more Gulf exports to reach international markets could remove part of the supply-risk premium built into Brent and WTI. However, the current proposal remains under negotiation, vessel traffic is still restricted, and wider political and military disputes involving Iran and the United States remain unresolved.
For now, traders are pricing in a greater possibility of improved oil flows, rather than a return to normal conditions.
The next major signal for the market will be whether Iran and Oman move from a proposed framework to an operational corridor and whether tanker traffic through the Strait begins to increase materially.
