January 15th — According to the commodity analysis system: On January 15th, the domestic average market price of isobutyraldehyde was 5,750 yuan per ton, remaining stable compared to the previous trading day. Upstream propylene prices fluctuated and rose, increasing the cost of isobutyraldehyde. Meanwhile, downstream neopentyl glycol prices declined, weakening downstream purchasing enthusiasm. The supply of isobutyraldehyde remained stable overall, leading to reduced upward support and increased downward pressure. Chempricehub's analysis of isobutyraldehyde gives a long-short score of -1.5. The rise in upstream propylene prices has increased the production cost of isobutyraldehyde, but the decline in downstream neopentyl glycol prices has suppressed purchasing enthusiasm. With supply remaining stable, overall upward support has weakened, and the risk of a decline has significantly increased. Spot prices may face downward pressure in the short term, with the market supply-demand dynamics trending weaker. Propylene, long-short score: 1 Propylene prices fluctuated and rose, reflecting increased support from upstream raw material costs or demand, which is favorable for propylene spot prices. Market supply may be tight, sustaining the upward price trend. Neopentyl glycol, long-short score: -1 Neopentyl glycol prices declined, weakening downstream purchasing enthusiasm. Soft demand has put pressure on spot prices. While there have been no significant changes on the supply side, market sentiment is bearish, and prices may continue to weaken.
