Oil surges past $85 as US reinstates Hormuz blockade and imposes transit toll
Brent crude hit a one-month high after Washington reimposed a naval blockade on Iran and announced a 20 per cent fee on cargo, while both sides escalated military strikes.
Brent crude rose above $87 a barrel on Tuesday, its highest since 12 June, after the United States formally reinstated its naval blockade of Iranian ports and President Donald Trump declared a 20 per cent toll on all cargo transiting the Strait of Hormuz. The move, coupled with a third consecutive night of US strikes on Iranian coastal targets, erased the price relief that followed a 17 June memorandum of understanding between the two countries. West Texas Intermediate climbed past $80, and Brent’s 9.6 per cent surge on Monday was its largest single-day gain since May 2020.
The mechanism driving the repricing is the Strait of Hormuz itself. Before the conflict, roughly one-fifth of the world’s oil and liquefied natural gas passed through the waterway. Shipping data showed tanker transits on Monday fell to the lowest level in two months, with only ten vessels crossing compared with a peacetime average of more than 130. Two UAE-flagged tankers were struck by Iranian cruise missiles in Omani waters, killing one Indian crew member and wounding eight others. Iran’s Revolutionary Guard also claimed attacks on US military facilities in Kuwait and Bahrain, while Yemen’s Houthi movement fired missiles at Saudi Arabia. The Joint Maritime Information Centre, led by the US Navy, said the blockade would be enforced from 4 p.m. New York time on Tuesday, covering all Iranian ports and coastal areas.
Viewed from Latin America, the UN Economic Commission for the region (CEPAL) estimated that 2026 average oil prices could be 20–25 per cent above 2025 levels, adding between 0.3 and 4.6 percentage points to annual inflation across the region. In Beijing, the impact is already visible: China’s June crude imports slumped 41.3 per cent year on year to their lowest in almost a decade, as weak domestic demand and export curbs on refined products compounded the supply shock. European natural gas prices rose to a three-month high, while US gasoline averaged $3.86 a gallon, nearly 30 per cent above pre-war levels. Equity markets reflected the uncertainty: the S&P 500 fell 0.7 per cent, the Stoxx Europe 600 lost 0.5 per cent, and Asian indices were mixed.
Analysts in London and Singapore warned that the key variable is the physical movement of crude. ANZ’s Soni Kumari said prices could remain in the $85–$90 range if disruptions persist, while Eurasia Group cautioned that tanker traffic could drop to 5–15 per cent of normal, a scenario that would push Brent toward $95. Citi noted that the probability of Iran walking away from the June understanding until after the US midterm elections had risen, which would keep prices elevated for longer. The immediate milestone to watch is the enforcement of the blockade and Trump’s scheduled address to the nation on Thursday, which may clarify the duration and scope of the new toll regime.

The United States reinstates the naval blockade and imposes a toll to guarantee freedom of navigation, and the market reacts accordingly.
Market logic naturalizes the US action by presenting the price surge as an automatic response to risk, without questioning the legitimacy of the blockade or toll.
The US action is presented without mentioning the Iranian missile attacks on UAE tankers and the Indian crew member killed, which would provide a context of provocation.
Iran denounces the American aggression as illegal and destabilizing, warning of a countdown to $95 oil and long-term regional consequences.
The narrative uses victimization and the threat of escalating oil prices to delegitimize the US action, framing it as an unprovoked assault on Iranian sovereignty.
The Iranian missile attacks on UAE tankers that triggered the US response are not mentioned, omitting the context of retaliation.
India suffers the human cost of the conflict with a killed crew member and faces the risk of energy supply disruption.
The personalization of the conflict through the Indian casualty makes the geopolitical tension tangible and urgent, shifting focus from abstract market moves to concrete human impact.
The 20% toll imposed by the US and the broader justification of Iranian attacks are not discussed, narrowing the frame to immediate human and market consequences.
Russia observes with irony the US move to monetize the strait, noting that such a toll has never been charged before.
The ironic detachment and surprise at the novelty of the toll imply that the US action is unprecedented and potentially overreaching, without directly condemning it.
The Iranian missile attacks on tankers and the Indian casualty are not mentioned, keeping the focus purely on market mechanics and geopolitical novelty.
