Lithium's Boom-Bust Cycle Was Bigger Than Most Commodities Ever See

Lithium’s price history over the early 2020s stands out even among generally volatile critical raw materials: prices rose several-fold as EV demand expectations accelerated, then fell dramatically over the following two years as new supply, much of it from newly developed Australian and Chinese sources, arrived faster than demand grew, and as EV sales growth itself slowed from its earlier pace in some major markets.

Putting a number on exactly how large the swing was

The same coefficient of variation introduced on cobalt’s economics page measures relative volatility independent of a series’ absolute level:

Applied to this site’s own published 2020-2024 annual average lithium carbonate price series ($7,000, $17,000, $60,000, $28,000, $13,000 per tonne), the coefficient of variation comes out to roughly 75%, more than double cobalt’s already-large ~34% figure computed the same way. That is a genuinely exceptional number for a major industrial commodity’s annual average price, not an exaggeration for effect.

Why the swing was this large

Lithium supply, like copper, takes years to bring online from discovery or expansion decision to production, whether that is a new hard-rock mine or a brine operation’s multi-year evaporation ramp-up covered on this material’s mining page. When 2021 and 2022 demand forecasts implied a looming shortage, producers and investors responded by committing to a wave of new capacity, much of which arrived just as demand growth moderated, producing a real, textbook commodity oversupply correction rather than one driven primarily by speculation. The scale of the swing reflects how young and comparatively small the lithium market still is relative to established commodities like copper, a given volume of new supply or demand shift moves lithium’s price proportionally further than the same volume would move copper’s.

A market still finding its pricing mechanism

Unlike copper or nickel, lithium has historically been traded substantially through direct, often confidential, long-term contracts between producers and battery or automotive manufacturers rather than through a single, deep, transparent exchange benchmark, though exchange-traded lithium contracts have been developing. This is a genuine, ongoing structural difference from more mature metal markets, and it means public price indices for lithium have historically reflected a somewhat thinner, less standardised set of transactions than the LME price does for copper or nickel.
