Brent crude fell 3.8 percent to $87.14 a barrel by midday Tuesday, putting it on track for a second consecutive decline after 13 gains in the prior 14 sessions. The drop came as Pakistan and Oman both sent delegations to Tehran to discuss a temporary shipping corridor through the Strait of Hormuz, injecting diplomatic optimism into a market that had been pricing escalation.
The scale of Brent's recent swing tells the story of how much uncertainty has been baked into the price. The benchmark zigzagged between $72 and $102 last month alone as expectations for a U.S.-Iran deal rose and fell. Tuesday's move suggests the market is assigning meaningful probability to a negotiated Hormuz arrangement, enough to override the announcement of fresh U.S. sanctions a day earlier.
Pakistan's delegation left Tehran after meeting with Iranian President Masoud Pezeshkian and other senior officials. The Pakistani military confirmed the talks focused on reopening the strait and reviving negotiations to end the Iran-U.S. conflict. Pakistan Interior Minister Mohsin Naqvi said the meeting with Pezeshkian was "very positive and productive."
Omani Foreign Minister Badr bin Hamad bin Hamood Albusaidi said talks with Iranian Foreign Minister Abbas Araghchi were "constructive" and that Oman is "hopeful" a temporary corridor for ships will open soon. The comments went further than a joint statement issued by both sides, which stated only that they had discussed a "proposed framework" to open a temporary passage—leaving the gap between diplomatic language and Oman's public optimism as the key open question.
Araghchi said on social media Tuesday that the meetings with both Pakistani and Omani counterparts stressed regional solutions. He said specific items on the table included the proposed corridor framework, joint mine-clearing operations and future management arrangements for Hormuz. Mine-clearing is the logistical chokepoint that diplomacy alone cannot resolve—naval mines laid in the strait require coordinated physical removal before commercial shipping resumes regardless of any political agreement.
Treasury Secretary Scott Bessent took a sharply different read of Tehran's posture. In a post on X, Bessent cited quotes from Iranian Parliament Speaker Mohammad Bagher Ghalibaf and President Pezeshkian about wanting the conflict to end, arguing that Iran's leadership is "admitting what the world can now see: the pressure is working." Bessent framed the comments as evidence that stepped-up sanctions announced Monday are producing results.
Both Iranian officials have since pushed back hard on that characterization. Ghalibaf wrote Monday on X that "Americans know that no one buys their bombast" and said Iran's trading partners had privately made clear they do not take U.S. economic pressure statements seriously. He added that the United States is "not in an economic position to further restrict its relations with other countries." Iran's economy minister said Tuesday the country had spent two years preparing for exactly this kind of sanctions escalation and predicted the U.S. plan would "suffer yet another defeat."
The original quotes from Ghalibaf and Pezeshkian appeared before both men publicly condemned the new U.S. sanctions package. Bessent's use of week-old quotes that the speakers have since contradicted is a factual tension the market appears to be tracking: oil fell, not rose, after his statement.
The sanctions themselves have a notable structural carve-out. The U.S. plan to ramp up economic pressure on Tehran spared Iran's trading partners from harsher secondary measures for now. That carve-out matters for global supply chains because Iran's largest oil buyers—primarily in Asia—continue to receive Iranian crude without facing the harshest penalties under the new framework. The practical effect is that sanction pressure targets Iranian government revenues without immediately cutting off physical oil flows to the degree a full secondary-sanctions regime would.
The Hormuz strait carries roughly 20 percent of global oil supply on a normal basis. Disruptions over the past months explain why Brent traded as high as $102 last month. At $87.14, the market is pricing in a partial but not complete resolution—a temporary corridor would restore some tanker traffic without returning to pre-war conditions.
The counterargument to Tuesday's price decline is straightforward: mine-clearing takes time and equipment, no corridor framework has been formally signed, and Iran has not publicly accepted any specific terms. Araghchi's statement referenced a "proposed framework"—not a finalized agreement. Every session of optimistic diplomacy over the past month has been followed by a reversal when talks stalled, as Brent's $30 range last month shows. The current diplomatic track involves at minimum three parties—Iran, Oman and Pakistan—each with different relationships to Washington, and any one of them hitting an obstacle stalls the process.
What the data shows clearly is that the market is no longer pricing a sustained escalation toward full strait closure. The 3.8 percent drop on a day when the United States announced new sanctions is a direct measure of how much weight traders are placing on the diplomatic track relative to the pressure track. Whether the corridor framework moves from proposed to operational depends on mine-clearing timelines that none of Tuesday's statements quantified.
