Market Data
Primary Supply
China dominates production at over 70% of global output; other contributors include Australia and the US, but supply is highly concentrated
Demand Trend
Moderate growth with a CAGR of 2.77-6.2%, driven by applications in NiMH batteries, catalysts, and energy storage; expected to remain stable but increase due to hybrid vehicles and fuel cells
Reserves
Abundant globally, with estimated 120 million tons of rare earth oxide (REO) equivalents; China holds about 44%, but resources are sufficient to meet near-term demand without immediate shortages
Risks & Substitutes
01
Relatively stable but concentrated supply.
02
Substitutes for some catalytic applications: other light rare earths.
03
Demand linked to automotive and electronic cycles.
