• WTI crude oil surged to $66.70 per barrel, its highest level since August, driven by escalating U.S.-Iran tensions and stalled nuclear negotiations.
  • Brent crude simultaneously climbed above $71.50, a six-month high, reflecting market fears over potential supply disruptions in the Persian Gulf.
  • The breakdown of talks in Geneva and U.S. military buildup have injected a significant geopolitical premium into oil prices, overriding underlying market fundamentals.

WTI crude oil futures jumped to a session high of $66.70 per barrel on Thursday, marking the highest level since August, as fears of a potential U.S.-Iran conflict rattled energy markets. Brent crude followed suit, surging above $71.50 to a six-month peak. These sharp gains reflect mounting concerns that escalating tensions could disrupt oil supplies through the critical Strait of Hormuz, where roughly one-third of global waterborne crude exports pass.

Nuclear negotiations between the U.S. and Iran have hit a snag, with U.S. Vice President JD Vance stating that Iran failed to meet key American demands during talks in Geneva. The diplomatic impasse has reversed earlier optimistic signals from Iranian officials, according to people familiar with the matter. The U.S. Administration warned Iran it would be "very wise" to make a deal, but efforts have made little headway, leaving markets on edge.

In response, the United States has strengthened its military presence in the Middle East, deploying aircraft carriers near the Persian Gulf. Sources cited by Axios indicate the U.S. is considering military action that could begin as soon as Saturday, involving a "massive, weeks-long campaign"—substantially larger in scope than previous strikes on Iranian nuclear facilities. Meanwhile, Iran conducted military exercises in the Strait of Hormuz, temporarily closing part of the waterway and heightening supply fears.

Oil prices jumped 4% on February 18, with an additional 1.6% gain in early European trading on February 19, as this geopolitical premium took hold. Beyond crude, heating oil prices also gained nearly 5%, while European natural gas prices rallied approximately 5.6% due to concerns about liquefied natural gas flows through the strait. Qatar, the world's second-largest LNG supplier, exported roughly 19% of global LNG trade in 2025, making it highly vulnerable to any disruptions.

Market dynamics show underlying tightness, with the ICE Brent futures curve indicating backwardation extending through 2026 and 2027. Buyers are increasingly reluctant to purchase sanctioned oil supplies, particularly Indian refiners reducing Russian purchases, which further constrains available supply. However, oil market fundamentals project a significant surplus for the first half of 2026, which would normally pressure prices downward. The International Energy Agency has reaffirmed that 2026 should be a year of surplus unless geopolitical events or Strait of Hormuz disruptions occur.

Price action is expected to remain volatile in the near term, with elevated global oil inventories capping upside potential. Traders will closely monitor whether the U.S. makes a final decision on military intervention and any Iranian responses. A prolonged conflict could significantly disrupt global oil supplies and trigger sustained price increases, while successful de-escalation or renewed negotiations could reverse the current premium. OPEC may resume supply increases in April, potentially adding downward pressure if tensions ease.

Attempts to reach U.S. and Iranian officials for comment were unsuccessful. The breakdown of Russia-Ukraine talks in Geneva also contributed to oil price increases, adding to the geopolitical uncertainty.
