Mosaic said it will suspend production at its Tapira and Catalão phosphate mines in Brazil after Brazil's National Mining Agency refused a deadline extension for stability certification on three tailings dams. The rules followed a deadly dam failure in January involving Vale.
Mosaic plans to supply Brazilian customers from Tampa and Peru.
Losing Brazilian phosphate output tightens supply in a market that is already short of feed phosphate and DAP. Import substitution and low seasonal demand should limit the price impact, but the suspension length is unclear.
After 151 past bullish policy events, DAP moved a median +0.0% over 5 sessions (50% higher; middle half -0.6% to +0.9%), and +1.9% over 20.
