PTT Public Company LimitedIran restricts shipping in Persian Gulf, tightening oil supply and raising prices, benefiting PTT as an oil producer.

PTT Public Company Limited reported the oil market situation for the week of September 7-11, 2026, with Brent crude averaging $94.51 per barrel, up $5.23, while West Texas Intermediate crude stood at $89.95, up $6.64, and Dubai crude at $100.28, up $7.96. The key factor was Iran's announcement to expand its shipping restriction zone to cover the Persian Gulf and beyond the Strait of Hormuz, following a U.S. attack on three Iranian oil tankers in the Gulf of Oman in retaliation for Iran's missile strikes on a U.S. warship. Additionally, seven OPEC+ member countries agreed to maintain production levels in October after completing compensatory production increases of 1.65 million barrels per day. Meanwhile, Ukraine attacked Russia's Ryazan refinery with drones, leading Russia to ban exports of refined products and require gasoline imports.
