ICE Brent Falls to $72 as Iran Diplomacy Erodes May War Premium
ICE Brent has shed more than a third of its value since the Hormuz crisis peaked in May as Iran talks advance, though re-escalation scenarios remain live.
ICE Brent crude front-month sat at $72.40 on Sunday (2026-06-28), well below the war-premium peaks reached when the Strait of Hormuz nearly closed in mid-May, as diplomatic progress on a US-Iran settlement reversed what had briefly been a supply shock of historic proportions. The unwind reflects how much the crisis rested on temporary buffers rather than a permanent reordering of supply.1
Morgan Stanley analysts calculated that US export surges and Chinese import reductions had together shielded the rest of the world from 9.3 million barrels a day of effective tightness — Washington adding 3.8 mb/d in export flows while Beijing pulled 5.5 mb/d from global markets — but warned the arrangement could not hold indefinitely if the strait stayed closed into June.3
The IEA reported that governments and industry had released 164 million barrels from strategic reserves by May 8 to offset the disruption. The agency warned inventories were declining at a record pace and that rapidly shrinking buffers amid continued disruptions would "herald future price volatility."4
China's position runs through both sides of this trade. China receives 37% of its seaborne crude imports through the Strait of Hormuz and purchases roughly 90% of Iran's exported oil, making it the party with most to lose from a sustained closure.2,6 Tehran cannot easily keep the strait closed without damaging its main oil buyer's economy, while Beijing's leverage over Tehran represents Washington's most credible diplomatic off-ramp.
President Trump's announcement of "great progress" in Iran talks caused Brent crude to slide 11.7% and WTI to plunge 13% in a single session, reflecting how fully the market had priced in an extended closure.1 Still, vessel tracking data from mid-May showed the strait had slowed to near standstill — just one vessel exiting the Gulf while two entered over a 24-hour period on Monday (2026-05-18) — illustrating how quickly sentiment turns on operational signals.5
Citi analysts, writing in late May, argued global oil markets were severely underpricing the duration of the supply disruption and its embedded tail risks. They set a near-term Brent crude target of $120 a barrel with a bull-case scenario of $150, citing the density of oilfield infrastructure across Saudi Arabia, the UAE and Kuwait within range of Iranian missiles. Carlos Bellorin of Welligence noted those fields are sprawling installations, difficult to protect fully.7,2
Iran's strategic capacity extends well beyond the waterway itself. The country holds the world's fourth-largest proven oil reserves, estimated at up to 170 billion barrels, and its missile and drone arsenal covers Gulf infrastructure across multiple states.6 SEB chief commodities analyst Bjarne Schieldrop described the broader miscalculation plainly in mid-May: "It has become quite clear now that this is the biggest bluff in history and it has gone horribly wrong."6
The disruption's cost has already moved through downstream markets. Lufthansa warned in late May that it faced a €1.7 billion increase in its jet fuel bill and would respond with higher fares and some flight reductions.1 Those costs remain embedded in carrier economics even as crude futures trace back toward pre-conflict territory.
Analysts had expected the strait to reopen by the end of May or early June.4 It did not, and the roughly 1 billion barrels in effective lost supply cited by Morgan Stanley's Martijn Rats has yet to be fully accounted for in market balances.3 A contrarian bullish position on ICE Brent crude front-month remains active, tied to physical supply risk rather than the diplomatic signals that have driven the recent price retreat.
A resumption of meaningful commercial shipping through the strait, and the pace at which the strategic reserve releases are rebuilt, will determine whether ICE Brent at $72.40 reflects genuine supply normalisation or a market running ahead of the physical facts.3,4
