Oil prices dropped sharply on Monday after U.S. President Donald Trump called off a planned military strike on Iran to pursue a diplomatic solution aimed at reopening the Strait of Hormuz and addressing Iran’s nuclear ambitions.
Brent crude futures fell $4.49 (5.11%) to $83.44 per barrel, while U.S. West Texas Intermediate crude dropped $5.39 (6.37%) to $79.28 per barrel by mid-afternoon London time. Both benchmarks recorded their largest single-day declines in absolute and percentage terms since the previous Monday, reversing weeks of volatility driven by regional tensions.
Trump cited regional allies’ requests for time to finalize a deal that would ensure "the Immediate, Complete and Total" reopening of the Strait of Hormuz and "an end to Iran’s nuclear threat." He posted on Truth Social: "Get to work, everybody, and get it DONE."
Iran denied any negotiations were underway. A statement from Iran’s government on Monday said no talks or meetings with the U.S. were planned, directly contradicting Trump’s justification for pausing military action. The discrepancy raised immediate questions about the feasibility of a diplomatic breakthrough.
Market Reaction: Stocks Rise as Oil and Yields Fall
U.S. stock indexes rallied on Monday, with the S&P 500 up 1.1%, the Dow Jones Industrial Average rising 1.0%, and the Nasdaq Composite gaining 1.7%. The gains followed a volatile July marked by oil price swings tied to escalating U.S.-Iran tensions. The 10-year U.S. Treasury yield fell to 4.688%, down from 4.75% late Friday, as investors sought safer assets amid reduced geopolitical risk.
Analysts attributed the market rebound to lower oil prices easing inflation concerns and improving investor sentiment toward global crude supply stability. The Organization of the Petroleum Exporting Countries and allies (OPEC+) had earlier approved a small production increase of 188,000 barrels per day for September, a move seen as a response to recent supply disruptions.
Shipping Disruptions Continue Despite Diplomatic Hopes
Despite the diplomatic overtures, maritime security risks persisted in the region. The UK Maritime Trade Operations reported three additional tanker attacks since Saturday, including incidents near the Strait of Hormuz and Bab el-Mandeb Strait. Six Saudi-flagged supertankers altered course in the Gulf of Aden, reportedly rerouting to southern Africa amid threats from Yemen’s Houthi movement to target Saudi shipping.
Shipping data showed traffic slowdowns in the Strait of Hormuz and Bab el-Mandeb, with only two Saudi oil tankers transiting the Red Sea over the weekend. The ongoing disruptions have contributed to tighter global oil supplies, which OPEC+ has attempted to offset with incremental production increases.
What’s Next: Can a Deal Be Secured?
Market analysts expressed skepticism about the prospects for a swift resolution. IG market analyst Tony Sycamore noted that the coming week could see a repeat of recent patterns, where hopes for a deal collapse as Iran maintains its leverage over key shipping routes. PVM analyst Tamas Varga warned that under current volatile conditions, the risk of miscalculation remains high.
The timeline for any potential agreement remains unclear. While Trump framed the pause in military action as a strategic move to facilitate negotiations, Iran’s denial of talks suggests a significant gap between the two sides. The absence of confirmed diplomatic channels raises concerns about whether the proposed deal can materialize before further escalation occurs.
Broader Economic Implications
Analysts highlighted the broader economic impact of the oil price decline. Lower crude prices were seen as a relief for global consumers facing persistent inflationary pressures. However, the underlying geopolitical risks—including ongoing tanker attacks and Iran’s regional influence—continue to pose threats to stable energy flows.
The coming days will be critical in determining whether the diplomatic overture leads to tangible progress or whether the cycle of tension and retaliation resumes. Investors, policymakers, and energy markets are closely monitoring developments for signs of sustained de-escalation.
