Shandong Haike Chemical has increased the propylene quotation by 100 yuan/ton to 9,200 yuan/ton. The plant is operating smoothly and shipments are normal, indicating a strong willingness to raise prices on the supply side, reflecting improved downstream demand or enhanced cost support, which directly benefits spot propylene prices. Combined with the futures data from April 20, 2026 (e.g., the closing price of the main contract 2605 was 8,343 yuan/ton, down 322 yuan), the spot price increase may drive a short-term rebound in futures prices, especially for near-month contracts, as spot prices are a leading indicator for futures. Overall, this constitutes a generally positive impact on the propylene market.
