Morning Market Briefing for MIBK (September 18, 2026)

Published on 2026-09-18

I. Key Focus Points

  1. Yesterday, the reference negotiation price for the MIBK market was 13,600 RMB/ton, a decrease of 200 RMB/ton.
  2. Yesterday, the mainstream reference negotiation price for the raw material acetone was 8,700 RMB/ton, a decrease of 25 RMB/ton.

Core Logic: Costs have declined, but spot supply remains tight, and holders' sentiment is relatively stable.

II. Price Table

Product Region Sep 17 Sep 16 Change Rate
Acetone East China 8,700 8,725 -0.29%
MIBK East China 13,600 13,800 -1.45%
Notes: 1. Acetone prices are based on National Standard Grade A; MIBK prices are based on enterprise standards. 2. All listed prices are cash-in-advance ex-factory prices in RMB/ton. 3. The two periods represent point-in-time prices from the past two working weeks, not weekly averages. 4. The change rate indicates period-over-period fluctuation.

III. Market Outlook

Yesterday, the center of gravity in the domestic MIBK market shifted downward as costs continued to fall. Downstream demand remained insufficient, leading to sluggish shipment rates among holders and lower offer prices. However, actual transaction volumes within the market were limited. Today, the domestic MIBK market is expected to move sideways. Attention should be paid to fluctuations in raw material acetone prices and their impact.

IV. Data Calendar

Data Item Release Date Previous Period Current Trend Forecast Remarks
Acetone Port Inventory Friday 10:00 AM 7,500 tons
MIBK Capacity Utilization Rate Thursday 5:00 PM 48.82%
