The MIBK market in the current period first rose, then stabilized, and finally declined. As of November 5, the price in East China stood at RMB 13,500/ton, a week-on-week decrease of 0.74%. Early in the week, the acetone market surged significantly. Driven by rising costs, holders maintained firm pricing and raised offers, but downstream follow-through was limited, restricting the increase in transaction centers. Subsequently, the acetone market turned downward, leading to a decline in costs. However, supplier inventory pressure remained low, so holders adopted a stabilizing strategy. Downstream demand inquiries were cautious, resulting in thin trading activity within the market. On Thursday, international crude oil prices dropped sharply, causing costs to fall significantly. Lacking sufficient psychological support, holders lowered their offers, while downstream follow-up was minimal, leading to a decline in actual transaction centers.
