The MIBK market continued its upward trend this period. As of September 10, the East China market price was 13,000 yuan/mt. During the week, the acetone market rose sharply, breaking through the 9,000 yuan/mt mark, causing MIBK industry costs to surge. Coupled with favorable external factors, the industrial chain showed a strong bullish atmosphere; supplier sentiment was boosted, companies raised quotations, and holders widely followed with higher offers. However, downstream buying sentiment was cautious, and inquiry activity was moderate. Nevertheless, low-priced cargoes were hard to find, and negotiation levels rose sharply.

  1. Analysis of Market Influencing Factors

(1) This week, the feedstock acetone market rose week-on-week, with acetone negotiations referenced at around 9,100 yuan/mt.

(2) MIBK weekly average gross profit increased by 34 yuan/mt from the previous period to around -1,549 yuan/mt.

(3) MIBK industry operating rate was around 49.12% this week.

  1. Next Week Market Forecast

The MIBK market is expected to have further upside next period. Focus on the following aspects:

Supply: Production is expected to fluctuate little next week, and spot availability is likely to remain tight.

Demand: As holidays approach, downstream stockpiling demand exists, but due to high MIBK prices, downstream purchasing is cautious.

Cost: The feedstock acetone market may continue to rise, providing strong cost support for MIBK.

Sentiment: The phenol-acetone market still has upward expectations. Combined with tight supply, holders are reluctant to sell and remain bullish.

Overall, the short-term market is expected to move higher at elevated levels.

    I see acetone feedstock cost surging lifting MIBK offers, but with operating rate near 49% and downstream demand cautious, margin risk may cap further upside unless buying picks up.
