Weekly Outlook for the MIBK Market

Published on 2026-09-28

I. Key Points

  1. Last week, the MIBK market reference price was CNY 13,500/ton, a decrease of CNY 100/ton.
  2. Last week, the mainstream reference price for the raw material acetone was CNY 8,700/ton, a decrease of CNY 100/ton.

Core Logic: Cost decline coupled with insufficient demand follow-through.

II. Price Table

Product Region Sep 24 Sep 18 Change Rate
Acetone East China 8800 8700 1.15%
MIBK East China 13500 13600 -0.74%
Notes: 1. Acetone prices are based on National Standard Premium Grade; MIBK prices are based on Enterprise Standards. 2. All listed prices are spot cash ex-works prices in CNY/ton. 3. The two periods represent snapshot prices from the past two working weeks, not weekly averages. 4. The change rate is the period-over-period percentage change.

III. Market Outlook

Last week, the domestic MIBK market declined. The raw material acetone generally trended downward, providing weak cost support. Downstream demand followed strictly by essential needs, with large-scale buyers securing materials at lower prices. Inventory holders focused on selling, leading to real transaction negotiations centering around lower levels with slight fluctuations. Today, the domestic MIBK market is expected to open with a wait-and-see attitude. Attention should be paid to fluctuations in acetone prices and their impact.

IV. Data Calendar

Data Item Release Time 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% ↗
Notes: 1. ↓↑ indicates significant fluctuation, highlighting data dimensions with changes exceeding 3%. 2. ↗↘ indicates narrow-range fluctuation, highlighting data with changes within 3%. 3. → indicates stability.

    MIBK’s drop to CNY 13,500/ton reflects weak downstream demand and falling acetone feedstock costs. With capacity utilization rising, margins are squeezed. I expect a wait-and-see stance as buyers monitor inventory trend..
