Benchmark Brent crude oil futures surpassed $100 a barrel on Wednesday, September 9, 2026, marking the highest level since July as escalating Middle East conflict disrupted energy flows from the Persian Gulf and Red Sea. The price surge follows intensified military strikes, tanker attacks, and tightening physical fuel markets worldwide.
International crude oil benchmark Brent crude futures rose past $100 a barrel on Wednesday, breaching the symbolic threshold for the first time since July 24. Intensifying conflict across the Middle East fueled immediate anxiety over global oil supplies, pushing futures up by roughly 2.94% to reach $100.80 a barrel by 1210 GMT, according to financial reporting from the region.
U.S. benchmark West Texas Intermediate crude followed suit, climbing past the $95 mark to touch $95.60 a barrel, marking its highest trading level since early June. Since the onset of the U.S.-Iran conflict on February 28, Brent prices have experienced severe volatility, peaking at $126.41 a barrel on April 30.
Strait of Hormuz Disruptions and Military Escalations
The latest price spike stems directly from a sharp kinetic escalation in the seventh month of the ongoing conflict between Washington and Tehran. In the latest exchange of strikes, the U.S. military sank five Iranian crude oil tankers overnight in response to attempted missile strikes by Iran against a U.S. Navy warship in the region. Tehran countered by targeting a U.S. base in Jordan and launching attacks on shipping vessels.
Shipping through the critical Strait of Hormuz—a waterway responsible for roughly 20% of global crude oil flows prior to the war—has remained severely constrained. Data provided by Rystad Energy Chief Economist Claudio Galimberti indicates that while roughly 8 million to 9 million barrels per day flowed through Hormuz in the week before fighting resumed on August 30, volumes have recently fallen below 2 million barrels per day.
“Oil investors are expressing their view about the impact of the latest bout of escalation in the Middle East in an unambiguous way. They are voting with their dollar, and this vote strongly indicates that unless the Strait of Hormuz re-opens, and oil starts flowing again uninterruptedly, supply will not be aligned with demand in the foreseeable future.”

Red Sea Threats and Global Refining Pressures
Beyond the Persian Gulf, supply routes faced fresh jeopardy as Iran-backed Houthi militants launched attacks on Saudi Arabian energy infrastructure, setting oil installations ablaze. These strikes threaten crude shipments traveling via the Red Sea, which has served as a key alternative transport corridor while the Strait of Hormuz remained restricted.
Additional vulnerabilities mounted in the Gulf of Oman, where port officials reported that a drone struck a tanker carrying approximately 2 million barrels of Iraqi fuel oil. Meanwhile, the United Kingdom Maritime Trade Operations agency reported that multiple merchant vessels sustained disabling fire overnight.
Physical crude markets and refined product sectors have actually traded above the triple-digit threshold for much of the year.
“We’re in a situation where actually, if we had normal refining margins, crude would be the equivalent of about $150.”

Political Pressures and Economic Forecasts
The elevated fuel costs deliver acute political pressure for the White House ahead of midterm elections, arriving just two months after motorists faced record high prices over the Labor Day holiday weekend.
Financial institutions are reacting swiftly to the tightening supply outlook. Major banks including Goldman Sachs, Bank of America, and HSBC have upwardly revised their crude price forecasts in recent days.
“The intensity and geographical breadth of tanker attacks — a highly uncertain variable — will remain a key driver of whether Gulf oil exports recover and how quickly.”
Daan Struyven, head of oil strategy at Goldman Sachs
Struyven noted that these unpredictable disruptions to maritime shipping will likely dictate the speed and success of any recovery for oil exports from the Gulf region.
