Oil prices surged over 4% on Wednesday as escalating tensions in the Middle East fueled supply concerns. President Donald Trump threatened strikes on Iranian infrastructure if shipping is targeted, while Secretary of State Marco Rubio indicated Iran is not serious about a peace deal and affirmed the U.S. commitment to protecting transit through the Strait of Hormuz.

Global oil markets experienced a significant upward surge on Wednesday, with prices jumping over 4%, as an intensifying conflict in the Middle East and assertive statements from U.S. officials fueled substantial supply concerns. This rally was prompted by President Donald Trump's stark warnings to Iran and Secretary of State Marco Rubio's skepticism regarding Tehran's willingness to de-escalate the situation.
The international benchmark, Brent crude futures, climbed more than 3% to conclude the day at $94.07 per barrel. Similarly, U.S. West Texas Intermediate crude advanced approximately 3%, settling at $86.83. Both key benchmarks have now seen increases exceeding 20% this month, clearly reflecting the growing instability across the region.

Speaking to reporters during a meeting of the Association of Southeast Asian Nations (ASEAN) foreign ministers in the Philippines, U.S. Secretary of State Marco Rubio reaffirmed Washington's willingness to pursue a diplomatic resolution. However, Rubio expressed concern that the Iranians "don't seem to be serious" about reaching a peace agreement, noting their breach of commitments made in a recent memorandum of understanding within just two weeks.
Rubio underscored the U.S.'s steadfast commitment to ensuring safe passage through the vital Strait of Hormuz. "We're going to continue to protect shipping, we think other countries should join us in that endeavor," he declared, adding a warning that "The president has many options available to him if they continue to insist on not being cooperative."
Further exacerbating regional instability, Iran's Houthi allies in Yemen announced an embargo against vessels loading or unloading cargo at Saudi Arabian ports. This action directly threatens Saudi oil exports, which have been rerouted through the Red Sea in an effort to circumvent disruptions in Hormuz.
Trump Issues Dire Warning to Iran
President Donald Trump intensified the rhetoric on Wednesday, threatening to bomb Iranian bridges and power plants, including those situated near the capital city of Tehran, should Iran target any ships in the Strait of Hormuz. In a Truth Social post, Trump asserted, "From this point forward, any time the Islamic Republic of Iran shoots at a ship in the Strait of Hormuz, whether it be by Missile, Rocket, Drone, or any other device or weapon, the United States will bomb and destroy ONE BRIDGE OR POWER PLANT..."
Concurrently, the U.S. military maintained its punitive actions, conducting an 11th consecutive night of strikes against Iranian targets. U.S. Central Command reported that these attacks specifically targeted Iranian military operations centers, maritime capabilities, aircraft hangars, drone storage facilities, and critical military logistics infrastructure.
Ryan McKay, an analyst with TD Securities, weighed in on the surging oil prices, suggesting that a range of $90 to $100 per barrel is now being supported by tightening market fundamentals. This is primarily attributed to slowed exports through Hormuz and heightened risks in the Red Sea. McKay elaborated, "This latest escalation and throttling of flows by Iran has in turn sped up that repricing and has again opened the door to fatter right-tail scenarios the longer it goes on."
