In April, the domestic MIBK market showed a trend of first rising and then falling. At the beginning of the month, the raw material acetone saw a wide rise, increasing cost pressure on manufacturers. Production companies raised their unit prices one after another, and the holding prices remained strong. However, after the ceasefire news was announced, the market's risk aversion quickly cooled down. Core raw materials such as international crude oil and acetone rebounded, and the cost side support was significantly weakened. Downstream stocks had bearish expectations, and the pace of market entry slowed down. However, the Zhejiang factory began to shut down for maintenance on the 15th, and the supply side tightened significantly in the short term. Production companies did not have a strong desire to adjust prices, but the terminal did not follow up under the downward trend. The atmosphere of on-site negotiations was sluggish, and the market focus was passively dragged down. At the end of the month, acetone rebounded at a low level, and cost pressures increased. Downstream demand for essential goods was replenished, and market prices were able to stop falling. The focus of actual order negotiations was consolidated and operated.
