Oil prices surged on Thursday, February 20, 2026, reaching a six-month high as escalating tensions between the United States and Iran raised the prospect of military intervention by Washington. Brent crude, the North Sea benchmark, rose 1.86% to $71.66 per barrel, peaking at $72.01 – its highest level since late July. West Texas Intermediate, the U.S. Equivalent, increased by 1.90% to $66.43 per barrel, reaching a high of $66.88, a level not seen since August.
The price increases followed a statement by President Donald Trump, delivered after brief negotiations with Tehran, issuing a ten-day ultimatum for a resolution to ongoing disagreements. Trump warned of “subpar things” should an agreement prove unattainable. Prior to the ultimatum, the White House had already signaled a hard line, with Press Secretary Karoline Leavitt stating that it would be “wise” for Iran to reach an agreement, and further asserting, “You’ll see many reasons and arguments in favor of an attack against Iran.”
Iran has maintained its “right” to enrich uranium for civilian purposes, including energy production. This position underscores a key point of contention in the stalled negotiations.
Market analysts attributed the price volatility to the heightened threat of military action. “The increasing threats of a possible military intervention… against Iran have introduced significant volatility into global energy markets,” observed Phil Flynn of The Price Futures Group. The fear of supply disruptions, particularly in the strategically vital Strait of Hormuz, is driving a risk premium into oil prices, Flynn added.
The United States has deployed a substantial naval and air force presence to the Middle East, a demonstration of force that analysts suggest could pave the way for potential military strikes against Iran. A military escalation carries the risk of damage to Iranian oil infrastructure, making Iran, one of the world’s top ten crude producers, vulnerable. More significantly, conflict could disrupt the Strait of Hormuz, a critical chokepoint through which approximately 20% of global oil supplies transit.
Oil prices initially fell after reports surfaced that the U.S. And Iran had agreed to talks, easing some conflict concerns, but quickly rebounded as Trump issued his ultimatum. The situation remains fluid, with no immediate indication of a breakthrough in negotiations.
