Brent reached about $114.72 as U.S.-Iran tensions lifted energy-market risk.
Why it matters: The conflict began in February 2026, and the latest price move shows how quickly markets are repricing risks to Middle East energy shipments. The Strait of Hormuz handles a major share of global oil and fuel flows, making tanker disruption a broader market concern.
- Brent was quoted at approximately $114.72 on October 23, 2026, after rising about 1%, its highest level since May.
- West Texas Intermediate crude moved above $100 a barrel on October 23; the cited reports do not provide its exact corresponding price or percentage move.
- Before the war began in February, shipments through the Strait of Hormuz represented about 20% of global oil and fuel flows, according to Reuters.
- A White House determination dated October 22 classified domestic petroleum production, refining and logistics capacity as critical to national defense.
Oil prices rose on October 23, 2026, as markets assessed the risk that the U.S.-Iran war, which the cited reporting describes as beginning in February, could disrupt tanker traffic through the Persian Gulf.
Brent was quoted at approximately $114.72 after gaining about 1%, according to Reuters reporting carried by The Guardian. The report described that level as Brent's highest since May. West Texas Intermediate futures also moved above $100, according to CNBC. The supplied reports do not establish whether the Brent figure was a settlement or intraday price, nor do they provide WTI's exact price and percentage move.
The immediate market exposure is the Strait of Hormuz. Before the war began, shipments through the waterway represented about 20% of global oil and fuel flows, according to Reuters reporting syndicated by Investing.com. That figure refers to shipments through the strait, not to 20% of global consumption or production.
The cited reporting supports higher oil prices and elevated tanker-traffic risk. It does not independently verify the previously reported claim that seven tankers were attacked or provide a directly attributable quote from an Iranian official saying the country was prepared for warfare. Those claims are omitted here.
On October 22, the White House issued a determination under Section 303 of the Defense Production Act that classified domestic petroleum production, refining and logistics capacity as critical to national defense. The determination establishes that classification; the cited text does not announce a specific expansion measure.
The Energy Information Administration projects Brent will average $105 a barrel in the fourth quarter, $14 above its prior monthly forecast, according to its October outlook.
By the numbers
- $114.72 - approximate Brent quotation on October 23, 2026, after a roughly 1% rise
- $105 - EIA forecast for average Brent prices in the fourth quarter
- 20% - approximate share of global oil and fuel flows shipped through the Strait of Hormuz before the war
Yes, but: The linked reports establish the oil-price move and the White House determination, but they do not provide independent verification of the seven-tanker attack count or a directly attributable Iranian statement about readiness for warfare.
