On September 15, 2026, oil prices increased due to supply concerns after attacks on Saudi Arabia's energy infrastructure left the East-West pipeline offline. Brent crude futures rose by $1.37 (1.3%) and West Texas Intermediate futures by $1.53 (1.51%). The disruptions raised fears of a broader Middle East conflict potentially affecting global oil supplies, with some analysts suggesting that Saudi Arabia could exhaust available export capacity within days if the pipeline is not restored soon.

Story summary
Oil prices surged above $100 a barrel as tensions in the Middle East escalated, particularly around the Bab el-Mandeb Strait and the Strait of Hormuz. In Yemen, Houthi rebels, backed by Iran, seized control of Perim Island and launched missile attacks on Saudi Arabia’s energy infrastructure, threatening vital shipping routes. This prompted concerns over global oil supply as the Houthis declared a blockade on Saudi vessels but allowed other commercial ships to pass through.
Meanwhile, in September 2026, Saudi Arabia's East-West pipeline, crucial for avoiding the Strait of Hormuz, was shut down after drone attacks, raising fears of potential disruptions to up to 4% of global oil supply. These developments came as talks between Gulf nations and Iran scheduled for Oman were canceled, heightening regional instability.
Additionally, an Iranian commercial ship was hit by an “unidentified projectile” near the island of Hengam in the Strait of Hormuz, causing casualties. U.S. President Donald Trump blamed Iran for the attack on Saudi Arabia's pipeline, while also suggesting that Iran-aligned Houthis did not want direct U.S. involvement but were targeting specific countries. These events underscored the complex and volatile geopolitical landscape affecting global energy markets.

Why this leaning score
This article does not take a side on a contested political
question, so it has no leaning score. That is an
answer rather than a gap: a match report or a rescue can be warmly
or critically written without being left or right, and scoring it
anyway is how approval of a subject gets recorded as a political
position.
