Since the escalation of the conflict between Iran and Israel, which intensified notably around June 13, 2025, oil prices for both West Texas Intermediate (WTI) and Brent Crude have experienced significant volatility. The conflict, marked by Israeli airstrikes targeting Iran's nuclear and oil infrastructure, triggered immediate reactions in global oil markets, driven by fears of supply disruptions in a region critical to global oil production. This analysis outlines the price movements since the conflict's outbreak and explores potential factors influencing future trends.
Oil Price Development Since the Conflict's Outbreak
The conflict's escalation on June 13, 2025, led to sharp increases in oil prices. Brent Crude, the European benchmark, surged by up to 13% overnight, reaching a peak of $78.50 per barrel, the highest since January 2025. By June 17, prices had moderated but remained elevated at around $74.93 per barrel, reflecting a 5.5–7% increase from pre-conflict levels. Similarly, WTI, the U.S. benchmark, jumped by approximately 6–9%, climbing from around $68.15 to $73.87 per barrel by June 17, with intraday highs near $74.64. Posts on X and various reports confirm these movements, noting the largest single-day gains since 2020, driven by heightened geopolitical tensions.
By June 16–17, markets showed signs of stabilization. Brent and WTI prices retreated slightly from their peaks, with Brent at $74.08–$75.18 and WTI at $73.16–$73.87. This partial pullback reflected market perceptions that the conflict might remain contained, coupled with reassurances from the International Energy Agency (IEA) about adequate global oil supplies and reserves of 1.2 billion barrels. However, prices remained above pre-conflict levels, incorporating a risk premium due to ongoing uncertainties.
Factors Influencing Future Oil Price Trends
Geopolitical Risks and the Strait of Hormuz: The conflict's potential to disrupt oil flows through the Strait of Hormuz, a chokepoint for roughly 30% of global seaborne oil trade, remains a critical concern. Iran, a major OPEC producer with 3.6–4 million barrels per day (mbpd) of output, could attempt to block this route in retaliation, potentially driving prices to $100–$150 per barrel, as speculated in some analyses. A blockade or attacks on regional oil infrastructure (e.g., in Saudi Arabia or the UAE) could exacerbate supply fears, pushing prices higher.
Sanctions and Supply Constraints: The U.S. and EU have signaled tighter sanctions on Iran, which exported significant volumes to China in 2023 despite existing restrictions. Stricter enforcement could reduce Iran’s 4% share of global supply, tightening markets. Conversely, OPEC’s spare capacity of over 6.5 mbpd, primarily from Saudi Arabia, could mitigate short-term disruptions, capping price spikes unless the conflict escalates further.
Global Economic Conditions: Weak global demand, particularly from China, has exerted downward pressure on oil prices in 2024, with Brent briefly dipping below $70 in September. A sluggish world economy in 2025 could continue to limit price gains, as forecasted by analysts like Goldman Sachs, who predict Brent at $70 by year-end 2025 due to an expected supply surplus of 0.8 mbpd.
OPEC+ Production Policies: OPEC+ decisions on production quotas will be pivotal. If the cartel maintains or increases output to offset potential Iranian losses, prices could stabilize. However, any reluctance to boost supply amid rising tensions could sustain elevated prices.
Market Sentiment and Speculation: Oil markets are highly sensitive to speculative trading. The current backwardation in futures markets suggests near-term supply concerns, but a shift to contango could signal expectations of oversupply. Investor sentiment, influenced by news cycles and de-escalation signals (e.g., potential nuclear talks with Iran), will drive short-term volatility.

Possible Development of Oil Prices
Oil prices remain heavily dependent on the development of the conflict. De-escalation, for example through negotiations on the Iranian nuclear programme, could reduce the risk premium and stabilise prices. Experts are forecasting an average Brent price level of around USD 70 for 2025, provided there are no major disruptions. However, strong fluctuations are possible in the short term, particularly if the conflict intensifies or the Strait of Hormuz is blocked. As early as Tuesday, only the suspicion of US intervention triggered a rise in oil prices in the night to Wednesday, which was partly given up again in the absence of US attacks, but returned to Tuesday's level by midday on Wednesday. This shows that the volatility of oil prices could remain at a high level.
