March 6th News: On March 6th, Yangzhou Shiyou's 320,000-ton/year phenol-acetone unit is operating normally. The price has been raised by 400 yuan to 5,800 yuan/ton. Contract shipments are proceeding as planned, with low inventory levels. Chempricehub Analysis: **Acetone** – Bull-Bear Score: 1.5 Yangzhou Shiyou has increased its acetone price by 400 yuan/ton to 5,800 yuan/ton, with low inventory levels, indicating tight supply and strong demand, which directly supports spot prices. The significant price increase, combined with low inventory, suggests that the spot market is likely to maintain an upward trend in the short term, supporting a bullish outlook. **MIBK** – Bull-Bear Score: 1 As acetone is an upstream raw material for MIBK, its price increase raises MIBK production costs. Yangzhou Shiyou's low inventory further strengthens supply-side pressure, indirectly benefiting MIBK spot prices. Driven by cost-push effects, the MIBK spot market may follow an upward trend, though the impact is expected to be milder compared to acetone, representing a moderate positive influence.
