Morning Market Brief for Mixed C5 (September 18, 2026)

Published on 2026-09-18

I. Key Focus Points

  1. Crude Oil: On September 17, U.S. officials hinted that the U.S.-Iran conflict is nearing its end, with multiple parties continuing to push for a de-escalation of tensions in the Middle East, leading to a drop in international oil prices. The NYMEX WTI October futures contract closed at $101.91/barrel, down $0.52/barrel (-0.51% WoW). The ICE Brent November futures contract closed at $104.82/barrel, down $1.01/barrel (-0.95% WoW). China's INE crude oil futures November 2026 contract fell by RMB 33.4 to RMB 805/barrel, while the night session dropped by RMB 42.5 to RMB 762.5/barrel.

  2. Gasoline: Yesterday, the gasoline market at Shandong refineries declined, with a production-sales ratio of 71%.

  3. Mixed C5: Yesterday, the price of mixed C5 in the Shandong market trended lower amid overall stability.

Core Logic: Overnight declines in crude oil prices led to downward pressure on the gasoline market and subsequently drove mixed C5 prices lower in Shandong.

IV. Market Outlook

Overnight crude oil prices declined, but the magnitude had limited impact on the broader market. Refineries have continued to accumulate gasoline inventories and are expected to cut prices today to boost sales. Market sentiment remains bearish, and trading activity for mixed C5 was sluggish yesterday. Chempricehub Information predicts that the mixed C5 market will see a slight decline today.

    Seeing Mixed C5 slide on easing crude and rising Shandong refinery inventories. With capacity utilization high and downstream demand soft, I expect continued margin pressure unless feedstock costs drop further.
