Platts, part of S&P Global, will amend specifications for five weekly phosphate price assessments effective July 3, 2025. Changes include defined basis locations, quantity ranges, a 5-to-30-day loading window, and a single closing value with standard high and low ranges.
Tighter benchmark definitions improve price transparency for DAP buyers but do not by themselves move phosphate prices. Feed buyers tracking DAP and phosphate costs should note the new reference points.
After 38 past neutral report events, DAP moved a median +0.5% over 5 sessions (61% higher; middle half -0.5% to +1.6%), and +3.9% over 20.
Moves of each commodity's benchmark from the last close before the event. Historical reads pool past events of the same kind; they describe what happened, not what will. Not investment advice.
