Brent jumped to $83 per barrel on Monday after the United States announced a fresh blockade that reignited concerns over energy shipments through the Strait of Hormuz.
The international crude benchmark soared by $7.29 or 9.59 per cent to $83.30 per barrel, while the US West Texas Intermediate (WTI) crude gained $6.73 or 9.42 per cent to trade at $78.14 a barrel.
US President Donald Trump announced that he would reinstate a blockade on Iran, forcing traders to once again price in the risk of prolonged disruption to energy flows through the Strait of Hormuz. The blockade, due to begin on Tuesday, will cover Iran’s entire coastline, ports and oil terminals, as well as all vessels regardless of flag.
The US President also said vessels receiving protection while transiting Hormuz would reimburse the country through a 20 per cent charge on cargoes, Reuters reported.
President Trump’s idea would mean that a 20 per cent fee on a supertanker that carries about 2 million barrels of crude at $80 per barrel would be equivalent to around $32 million, or an additional cost of $16 per barrel.
“This is significantly higher than the $1/bbl toll for which Iran has been pushing,” ING’s strategists said.
The proposal was also criticised by the International Maritime Organisation (IMO) because international law does not provide for mandatory transit fees through straits used for international navigation. Energy companies have also rejected similar proposals previously advanced by Tehran, arguing that freedom of navigation remains a cornerstone of global maritime trade.
Iran’s top joint military command had earlier said it would not allow the US to intervene in the management of the strait, and any attempt by the US to transit without its authorisation would be confronted.
Analysts now expect countries to work on ways to permanently bypass the Strait of Hormuz. Goldman Sachs estimated that expanding pipeline capacity in the Middle East could shield more than 60 per cent of pre-war Gulf oil exports from any future Hormuz disruptions by the end of 2028.
The bank’s base-case forecast assumes pipeline capacity bypassing Hormuz will rise by 3.8 million barrels per day by end-2027 and 7.3 million barrels per day cumulatively by end-2028, taking total effective bypass capacity to more than 14 million barrels per day by end-2028.
The Organisation of the Petroleum Exporting Countries (OPEC) has trimmed its 2026 global oil demand growth forecast for the third straight month, even as crude production rebounds across the Gulf and tanker traffic slowly returns to the Strait of Hormuz.
In its monthly oil market report released Monday, OPEC lowered expected oil demand growth this year to 780,000 barrels per day, down another 190,000 barrels per day from last month’s forecast. The producer group still expects stronger consumption than many other forecasters, including the International Energy Agency, and even raised its demand growth estimate for 2027 by 210,000 barrels per day to 1.94 million barrels per day.
