The OPEC+ alliance has decided to maintain its current oil production policy for October 2026, keeping levels consistent with September 2026 requirements. Geopolitical conflicts in Iran and Ukraine have caused actual production to lag behind planned increases. Maritime escalations in the Strait of Hormuz have intensified disruptions, with traffic reportedly falling below 20 percent of pre-war capacity. Following ballistic missile attempts against U.S. naval vessels, U.S. Central Command reported the destruction of five Iranian crude oil tankers on September 8, 2026. In retaliation, the Iranian Revolutionary Guard Corps claimed to have targeted two U.S. destroyers and an American military base in Jordan. Jordanian authorities reported that air defense systems intercepted 18 of the 20 missiles.

Tensions expanded on September 10 as Iran’s Revolutionary Guards announced plans for a new shipping prohibited zone extending into the Arabian Sea. Simultaneously, Houthi militants launched missile and drone attacks against three cities in southwestern Saudi Arabia, while also gaining control of the port city of Mocha in Yemen. This takeover has heightened maritime security concerns in the Red Sea.

These confrontations have driven Brent crude to exceed $105 per barrel, with recent surges seeing Brent reach $109.29 and WTI hitting $103.91. In the United States, the national average diesel price has exceeded $6 per gallon for the first time, raising fears of reignited inflationary pressures. Global markets have reacted with volatility; major stock indices have faced declines, while U.S. Treasury yields have climbed. In India, the price surge is expected to increase import costs and pressure the trade balance, as government oil companies face mounting losses.
