Year-by-year annual average price for cesium in USD/kg, sourced from U.S. Geological Survey, Mineral Commodity Summaries 2025. Cesium metal (99.9%+); supply nearly exclusively from Tanco mine, Canada.
Cesium atomic clocks define global time standards that underpin GPS navigation, internet synchronization, and financial systems. Canada controls most of the world's cesium reserves. Demand is driven primarily by Cesium atomic clocks (GPS and telecommunications), Oil and gas drilling fluid additive, Infrared detectors and night vision. Supply is concentrated in Canada, Zimbabwe, Namibia, so output disruptions or trade-policy shifts in those countries are the main long-run drivers of Cesium prices.
