Energy markets experienced significant volatility on Thursday as diplomatic tensions between Washington and Tehran escalated. Brent crude registered approximately 4% growth, reaching $106.34 per barrel, while West Texas Intermediate advanced 3.7% to settle at $93.66.

These increases reversed the previous session’s decline of over 2%, which had been fueled by temporary market optimism regarding potential diplomatic breakthroughs. However, that sentiment quickly evaporated.
Iranian leadership publicly refuted claims of direct diplomatic engagement with Washington. Tehran’s representatives emphasized substantial outstanding disagreements and presented their own stipulations, prominently featuring absolute sovereignty over the strategic Strait of Hormuz.
Washington responded by reaffirming that diplomatic channels remain active. During a Wednesday evening fundraiser, President Trump stated that Iran “desperately wants an agreement, but they’re reluctant to admit it publicly.”
Iranian legislators are currently drafting legislation that would impose fees on vessels transiting the strait under the pretext of security services. According to the semi-official Fars news agency, this proposal should reach completion within the coming week.
