Critical for magnet performance and green energy technologies. One of the most supply-constrained rare earths.
Which countries produce terbium?
Terbium production is highly concentrated: China (90%), Myanmar (5%), Australia (3%).
How liquid is physical terbium?
Less liquid than listed products: there is no exchange price for terbium that a private holder can trade on. Resale is negotiated with industrial buyers or traders, and the price and timing depend on form, purity, lot size and demand at that moment. It should be treated as a long-horizon holding.
