January 16th News: On January 16th, Yunnan Huaye Phosphorus Chemical Industry's yellow phosphorus plant underwent shutdown for maintenance. Chempricehub's analysis of yellow phosphorus, with a long-short score of 1.5: The shutdown of Yunnan Huaye Phosphorus Chemical Industry's yellow phosphorus plant for maintenance has led to a reduction in supply, which is expected to drive up the spot price of yellow phosphorus. This event directly reduces short-term market supply, creating a favorable situation under stable demand conditions. Although the maintenance is temporary, Yunnan, as a key production area for phosphorus chemicals, may amplify upward price pressure due to localized supply contraction. The score is based on a moderately strong positive impact of the supply disruption on spot prices.
