Brent Recovers to $103 as Hormuz Flows Remain Below Pre-Conflict Levels
US-Iran diplomacy cut oil from crisis highs but has not restored Hormuz flows, leaving ICE Brent crude front-month above $100 in September.
ICE Brent crude front-month at $103.37 a barrel as of September 19 (2026-09-19) sits roughly $20 above the low touched on August 3 (2026-08-03), when Trump's decision to call off another round of planned strikes on Iran sent the benchmark down more than 5% in a single session. The recovery suggests that successive diplomatic breakthroughs have narrowed but not erased the price gains crude accumulated after the Strait of Hormuz was effectively closed to commercial traffic earlier this year.6
The conflict that sealed the waterway took hold roughly 10 weeks before mid-May 2026, when Washington's rejection of an Iranian counter-proposal prolonged the shutdown and pushed oil higher. At its peak, the closure affected an estimated 20 million barrels per day of global oil supply, roughly one-fifth of worldwide production, according to the European Central Bank's latest market assessment. Ships that did transit paid an average of around $2 million per passage, an Iranian lawmaker said.1,5,3
Trump's most prominent claim of operational success came on June 11 (2026-06-11), when he posted to social media that a secret US military operation called Project Freedom had over the prior month escorted more than 200 commercial ships carrying over 100 million barrels of oil through the strait. Prices had already been falling on diplomatic optimism.2
Three days later, on June 14 (2026-06-14), Trump declared a US-Iran agreement "complete" and announced the "immediate toll-free reopening" of the Strait of Hormuz. ICE Brent front-month fell below $85 a barrel on the news. Some analysts had been positioned for a move into the mid-to-high $100s range; the deal closed that trade.3
The respite did not last. By July 14 (2026-07-14), ICE Brent front-month had climbed back to $87 a barrel, its highest level since June, as NBC News reported renewed US-Iran hostilities and a Houthi blockade of Saudi ports re-ignited supply fears. From the Sunday (2026-07-12) night open, Brent had already risen more than 10%, and year-to-date gains stood at roughly 40% at that point. Trump's separate decision to drop a proposed Hormuz transit fee drew little response from the market.4,6
A second sharp reversal came on July 27 (2026-07-27), when Brent settled 6.6% lower at $90.41 a barrel and NYMEX WTI fell 5.7% to $84.23, as renewed de-escalation signals prompted traders to pare positions, ibtimes.sg reported. Intraday, Brent fell as much as 10% and WTI nearly 9% before both recovered part of their losses by the close. Strait of Hormuz exports remained significantly below prior levels throughout that session.5
August 3 (2026-08-03) brought the deepest single-day move of the cycle. Trump cancelled another round of planned military strikes on Iran, sending WTI futures to $79.77 a barrel and Brent to $83.47, OilPrice.com reported. The selloff compounded an already volatile July in which both benchmarks had surged more than 20% on fears of prolonged supply disruptions. OPEC+ added further downward pressure, approving a quota increase of roughly 188,000 barrels per day for September as it unwound one tranche of its voluntary cuts.6
By August 5 (2026-08-05), Brent and WTI had both shed more than 10% in a single week, with traders citing progress in US-Iran talks involving Oman, Zeebiz reported. Analysts said a confirmed peace deal paired with full Hormuz reopening would weigh further on crude.7
Brent has since retraced the entire August decline to sit above $103 a barrel. Hormuz exports were still significantly below pre-conflict levels as of late July (2026-07-27), and no subsequent diplomatic confirmation has publicly established that full normalisation has occurred. OPEC+'s September quota addition provides some supply offset, but months of constrained throughput through a route carrying roughly 20% of global seaborne oil trade have left physical balances tight enough to prevent any sustained return toward pre-conflict price levels. Whether formal Hormuz flow data confirms a meaningful recovery will be the signal traders are watching most closely in the weeks ahead.5,6
