The global phosphonate market in late September 2025 remained entrenched in a prolonged bearish balance, weighed down by steady feedstock inflows and stable operating costs across regions. In the United States, phosphonate values experienced a sharp week-on-week decline, marking the twelfth consecutive week of losses, as uninterrupted deliveries of yellow phosphorus, phosphorus trichloride, and other key intermediates swelled availability. India acted similarly, experiencing another sharp drop on the back of smooth raw material imports, high inventories, and muted municipal procurement, despite steady offtake from water boards and refineries. Similarly, Germany experienced a slight drop and continued its extended downtrend amid fully integrated production and unchanged EU trade conditions. China was the outlier with phosphonate levels remaining stable against its sideways pattern of previous weeks. Analysts caution that unless production rates are curbed, the continuing oversupply, and lack of cost pressure could even take phosphonate values softer in early October.
