Global crude oil markets experienced a significant rally on Monday following President Donald Trump’s decision to reject a diplomatic proposal from Iran that would have restored commercial traffic through the Strait of Hormuz within a week.

Speaking from the White House, Trump stated firmly, “I reject their proposal,” emphasizing that the terms presented by Tehran fell short of American interests and expectations.
Iran’s Demands Remain Unchanged
The Iranian government’s proposal outlined a temporary cessation of hostilities. In return, Tehran requested that Washington withdraw its naval forces from the Persian Gulf, reduce military operations in the region, and eliminate economic sanctions targeting Iranian petroleum exports.
Following the American rejection, Iranian officials reaffirmed their commitment to these preconditions. The government in Tehran has shown no indication of modifying its stance.
In remarks to Axios, Trump indicated optimism that negotiations would continue in the near term. “They want to make a deal, but it is not the deal that I want to make,” he explained in comments released over the weekend.
Qatar has taken on a mediating role between the United States and Iran. According to Axios reporting, indirect diplomatic discussions could commence as soon as this Monday.
Market Response to Diplomatic Breakdown
Brent crude futures advanced 2.8% to reach $107.27 per barrel during Monday morning trading. West Texas Intermediate crude saw a nearly 2% increase, touching $94.13 per barrel.
Over the entire month, Brent has registered an 18% gain. Prices had temporarily declined more than 2% on Friday when initial reports of the potential ceasefire emerged.
The Strait of Hormuz serves as a critical chokepoint, typically facilitating approximately 20% of global oil and natural gas shipments. Maritime traffic through this strategic waterway has declined substantially since regional tensions intensified.
Compounding supply concerns, Iranian-supported Houthi militants have escalated military operations in Yemen. Saudi Arabian defense forces reported intercepting two ballistic missiles and two unmanned aerial vehicles during the weekend.
Diesel fuel costs across Europe and North America have reached unprecedented levels. Supply constraints from Middle Eastern producers and Russia continue driving prices upward.
However, some positive supply developments emerged. Trump revealed that more than 20 million barrels of crude oil successfully transited the strait over the weekend period.
Global equity markets displayed mixed performance. Seoul’s market declined 2.7% upon reopening after a holiday, while Tokyo, Shanghai, and Mumbai exchanges also recorded losses.
Conversely, Hong Kong, Sydney, and Singapore markets posted advances. European markets in London, Paris, and Frankfurt opened with gains.
Fixed-income markets also reacted, with yields rising. A global benchmark for sovereign debt yields exceeded 4% last week for the first time since 2007, based on Bloomberg data.
Escalating energy costs intensify inflationary pressures globally. This development increases scrutiny on the Federal Reserve as its late-October policy meeting approaches.
CME Group’s FedWatch probability tool indicates greater than 65% odds for consecutive interest rate increases. Market participants are also anticipating the Fed’s preferred inflation metric and employment data scheduled for release this week.
Stephen Innes, analyst at Quintex Intel, noted that geopolitical tensions have intensified following the diplomatic rejection. He observed that petroleum prices have climbed while Asian equity indexes have weakened accordingly.
Innes suggested that financial markets continue to anticipate an eventual resumption of negotiations between the parties. He indicated that public posturing and rhetoric may persist before substantive talks recommence.
Currently, Iranian authorities have not retreated from their stipulated conditions. While Trump has suggested discussions could resume within days, no concrete meeting has been scheduled.
