President Donald Trump said on Sunday that a deal has been "largely negotiated" to end the war between the U.S. and Iran [3].

The agreement is critical because it seeks to prevent Iran from acquiring a nuclear weapon, and aims to reopen the Strait of Hormuz for commercial shipping.

Negotiations center on a memorandum of understanding designed to end a conflict that has lasted nine and a half weeks [1]. The process has been facilitated by mediators from Pakistan, who have worked to bridge the gap between Washington and Tehran [2].

Despite the president's optimism, Iranian officials have offered a more cautious assessment. Esmaeil Baghaei, a spokesman for the Iranian Foreign Ministry, said that Iran has not yet reached a final decision on the U.S. proposal conveyed through Pakistani mediation and remains in the review phase [2].

Reports of the potential deal have coincided with significant market activity. According to one report, $920 million in crude oil short positions were placed before the news of the deal surfaced [4].

Earlier this month, sources familiar with the mediation said that the two nations were getting close to agreeing on the memorandum [1]. The framework is intended to address the immediate cessation of hostilities, while establishing a long-term path for managing Iran's nuclear program [1].

President Trump's statement on May 24 follows weeks of diplomatic maneuvering to stabilize the Middle East [3]. The U.S. administration has emphasized the need for a deal that ensures regional security, and the free flow of global energy supplies.

A deal has been "largely negotiated" to end the Iran war.

The discrepancy between the U.S. and Iranian statements suggests a gap in the final stages of diplomatic ratification. While the U.S. is signaling a victory to stabilize oil markets and secure a nuclear framework, Iran's 'review phase' indicates that specific terms of the memorandum of understanding may still be under contention. The timing of massive oil market bets suggests that traders are anticipating a rapid shift in geopolitical risk if the deal is formalized.
