Phosphate rock costs, prices and resources interaction

Area of Science:

• Agricultural Economics
• Resource Management
• Geology

Background:

• The international phosphate sector faces recurring price volatility.
• Global food security is linked to phosphate rock availability and cost.
• Historical analysis of phosphate production costs and market prices is crucial.

Purpose of the Study:

• To analyze trends in phosphate rock production costs and market prices over three decades.
• To investigate the drivers of phosphate rock price volatility.
• To assess the impact of production costs and price volatility on food prices and phosphorus recycling.

Main Methods:

• Analysis of phosphate rock production costs from industry studies in 1983 and 2013.
• Examination of phosphate rock market price trends over a 30-year period.
• Correlation analysis between production costs, investment costs, and market prices.

Main Results:

• Global average phosphate rock production costs increased by 27% nominally but decreased in real terms between 1983 and 2013.
• Phosphate rock market prices exhibited significant volatility, with major spikes unrelated to production cost increases.
• Escalating investment costs for new mine capacity were identified as a key driver of price spikes.

Conclusions:

• Phosphate rock price volatility, driven by investment costs, poses a greater threat to food prices than rising production costs.
• Future phosphate price spikes are anticipated.
• Economic incentives will increasingly influence phosphorus recycling, potentially reducing reliance on legislation.
