Brent Rebounds 12% From Ceasefire Lows as Iran's Supply Restoration Lags Market Expectations
Two months after Washington and Tehran signed a ceasefire, crude is trading $9 above its signing-day low as the pace of Iranian supply recovery trails what markets priced during June's sell-off.
ICE Brent crude front-month was trading at $86.81 a barrel on Wednesday (2026-08-26), roughly $9 above the $77.41 touched when the US and Iran formally signed their ceasefire on June 18 (2026-06-18). That 12% recovery, achieved over two months in which the prevailing trade has been to sell the supply-return story, suggests the market may have priced in a faster and cleaner normalization of Iranian output than the physical reality is delivering.4
The ceasefire logic was coherent at the time. The June 18 (2026-06-18) interim deal ended the conflict, reopened the Strait of Hormuz and waived US sanctions on Iranian oil, according to RTE. Brent futures dropped $2.14, or 2.69%, to $77.41 that day, and WTI fell $2.36, or 3.07%, to $74.43. By late June, crude had fallen below its pre-war levels entirely, as traders increasingly bet on a surge in supply, according to The Independent, with analysts pointing to stranded Gulf cargoes finally releasing to market.4,5,6
One specific clause in the draft deal now warrants scrutiny. Iran's semi-official Mehr news agency said the draft called for reopening the Strait of Hormuz within 30 days under Iranian arrangements, as reported by The Hindu Business Line. Thirty days from June 18 puts that deadline in mid-July. Brent has added $9 since the signing. Either the restoration of Iranian crude flows has run behind that schedule, or demand has been absorbing supply that analysts expected to overwhelm the market by now.3
Production damage adds a layer of uncertainty that the ceasefire euphoria may have compressed. Analysts noted that how quickly Middle Eastern producers could resume output following war-related infrastructure damage remained unclear, as did the pace at which shipping would return to the region. Fitch Ratings argued the episode was primarily a logistical shock rather than a lasting destruction of production capacity, pointing toward an eventual return to oversupply. But logistical shocks affecting loading terminals and port infrastructure can set back export restoration by months even when wellhead capacity is largely intact.3,5
This is not the first time in this cycle that the market priced a diplomatic outcome before the barrels confirmed it. On Monday (2026-06-08), Trump and Iran's deputy foreign minister announced an initial deal to end hostilities and resume Hormuz traffic; Brent fell $3.58, or 4.10%, to $83.75, and WTI dropped $4.01, or 4.72%, to $80.87 by early European trading, The Hindu Business Line reported. Both contracts fell more than 3% again on Friday (2026-06-12). Earlier in the cycle, when Iran poured cold water on a separate set of deal expectations on Friday (2026-05-22), Brent reversed sharply and rose 0.78% while WTI climbed 0.20% to $96.54, OilPrice.com reported. The June ceasefire was genuine. But the reflex to price full supply normalization before physical flows are verified has appeared repeatedly in this episode.3,2
One supply-side factor will not recur. All 32 IEA member countries agreed in May to release 400 million barrels from strategic reserves, representing 20% of total IEA holdings, to ease constraints during the Hormuz closure, according to IEA executive director Fatih Birol, as the BBC reported. Those barrels suppressed prices during the conflict peak and will not reappear. With 80% of IEA stocks still held, Birol indicated further releases remained possible, but reserves deployed in one crisis eventually need to be rebuilt, creating a demand layer that a straight-line oversupply model discounts.1
Swissquote senior analyst Ipek Ozkardeskaya said in late June that evidence of tankers transiting the Strait with satellite tracking systems activated had reassured markets and helped push prices lower. Actual Iranian crude loadings measured in barrels per day, not sanctions waived, are what will resolve the debate. If those loadings stay below pre-conflict run rates into the fourth quarter, the scale of the June sell-off will be difficult to justify on supply fundamentals, and Brent's current level will read as a rerating rather than a short-covering bounce.6
