Brent Crude Rises to $103.73 Per Barrel on September 30, Climbing 1.1% as Iran Diplomacy Stalls
Record added
Brent crude futures rose $1.14, or 1.11 percent, to $103.73 per barrel on September 30, 2026, while West Texas Intermediate gained 15 cents, or 0.30 percent, to $89.50 per barrel, according to Inkl, Forbes, and Trading Economics. Brent is on track for a monthly gain of around 14 percent, its biggest rise since July, and has climbed 59.50 percent compared to the same time last year. The rally followed President Trump's rejection of Iran's latest proposal to reopen the Strait of Hormuz, with Iranian officials casting doubt on the possibility of reaching an agreement before US midterm elections in November. Multiple sources reported Brent had earlier traded between $102.90 and $106.04 on September 29, with significant intraday volatility.
The sustained price elevation reflects the continuing blockade of the Strait of Hormuz, which has reduced visible transits through the waterway to 1 vessel on September 27 compared to a pre-crisis baseline of approximately 85 per day, according to IMF PortWatch data cited by Straits.Live. While Saudi Arabia restored its East-West pipeline to full 7 million barrel per day capacity in April and has maintained elevated crude exports via the Red Sea port of Yanbu, roughly 5 million barrels per day, analysts warn that prolonged closure creates vulnerability to further supply disruptions. The outcome of US-Iran talks, mediated by Qatar, remains the single largest near-term supply variable for global energy markets; any breakdown prolongs the tightest oil market conditions in over two decades.
