Brent crude oil surpassed the $90 per barrel mark on Monday, driven by escalating geopolitical tensions in the Persian Gulf that are constricting vital tanker routes. The international benchmark for oil prices climbed 3.05% to settle at $90.79, its highest point since June 11. This surge follows a significant 15.9% increase observed over the preceding week. Concurrently, the US West Texas Intermediate (WTI) crude benchmark also saw gains, rising 2.65% to $84.68 a barrel.
Gulf Supply Fears Intensify as Strait of Hormuz Traffic is Disrupted
The recent price rally is directly linked to ongoing military actions between the United States and Iran, which have heightened concerns over the security of shipping lanes. Reports indicate a ninth consecutive night of US strikes targeting Iran, alongside alleged Iranian actions against vessels reported by Kuwait and Bahrain. These developments have placed significant pressure on the Strait of Hormuz, a critical chokepoint for global energy trade.
The Strait of Hormuz accounts for approximately one-fifth of the world’s oil trade, making it indispensable for oil exports originating from the Persian Gulf region. While traders are not currently factoring in a complete shutdown of the waterway, the increased security risks, reduced vessel traffic, and general uncertainty surrounding consistent oil exports are driving market sentiment. Data from LSEG revealed a notable decrease in traffic, with only four vessels transiting the strait on Sunday, down from eight the previous day. Despite the constraints, some activity persists, with at least three product tankers and one very large crude carrier reportedly entering the strait since Friday to load oil, indicating that traffic, while reduced, has not ceased entirely.
Official statements from Washington assert the enforcement of a naval blockade on Iranian ports. Tehran, conversely, claims its actions are directed at vessels violating its navigation rules. Adding to the regional instability, a vessel was reported ablaze near Oman early Monday, though the cause remained unverified at the time of reporting.
Tight Inventories Bolster Case for Higher Oil Prices
Analysts suggest that the current price surge may possess greater staying power compared to previous geopolitical-driven rallies. This is largely attributed to historically tight crude oil inventories, which offer less buffer against potential supply disruptions. Amarpreet Singh, an analyst at Barclays, noted that the coming days would be crucial in determining the sustainability of regional exports under the prevailing blockade conditions imposed by both sides.
Singh cautioned that oil markets might be underestimating the impact on inventories. Barclays estimates that current stockpiles are at their lowest levels in five years. Inventories typically function as a market’s shock absorber; ample storage allows refiners to substitute delayed oil shipments with barrels held domestically. However, when stockpiles are depleted, a sustained reduction in exports can compel buyers to compete fiercely for available supplies, thereby driving prices upward.
Expert Outlook: $105 Brent Crude Not Out of the Question
David Roche, a strategist at Quantum Strategy, anticipates that declining oil exports from the Persian Gulf could lead to critically low inventory levels by September, affecting supplies even in the United States. In a recent note, Roche advised investors to maintain a “long” position on Brent crude, setting a price target between $95 and $105 a barrel.
While the $105 per barrel mark is considered a potential scenario rather than a universally agreed-upon forecast, it is not an isolated projection. Earlier in June, Barclays had projected an average Brent price of $96 for 2026 and foresaw a supply deficit in the third quarter of the current year, citing a lag in production recovery compared to improving shipping flows.
Factors Influencing Future Oil Price Movements
The trajectory of oil prices towards the $105 level hinges on several key factors. A sustained restriction of traffic through the Strait of Hormuz, coupled with a continued decline in Persian Gulf exports and minimal progress in diplomatic efforts, would likely fuel further price increases. Additionally, any physical damage to tankers, oil terminals, pipelines, or other critical infrastructure could accelerate this trend, forcing refiners into a more intense competition for scarce near-term oil cargoes.
Conversely, the potential for a sharp price reversal remains significant should geopolitical tensions de-escalate. An increase in the number of successful tanker transits, credible negotiation outcomes, or clear evidence of normalizing export levels could lead to a reduction in the risk premium currently embedded in Brent crude prices. Market participants will be closely monitoring developments in the Strait of Hormuz and broader diplomatic engagements to gauge the future direction of oil markets.
