Lithium, Cobalt Open Interest Soars as Prices Plunge
Slower-than-expected consumer adoption of electric vehicles (EVs) in 2023, wavering economic growth in China since the pandemic and burgeoning lithium and cobalt supplies have sent prices of both metals lower even as producer/hedger interest in futures contracts has expanded dramatically. China is the biggest market for EVs, while lithium and cobalt are used in the manufacture of EV batteries. Since their 2022 peaks, cobalt prices have fallen by over 50% from $40 to $16.5 per pound, while the price of lithium hydroxide has fallen nearly 75% from $85 to $23 per kilogram (Figure 1).

Open interest (OI) in both lithium hydroxide and cobalt has increased significantly amid the price declines, stretching out well into 2025, which is more than typical in the metals complex. As of the end of October 2023, lithium and cobalt futures had open interest as far out as March and December 2025, respectively. These futures curves point towards only a modest hope of recovery in cobalt prices, with December 2025 contracts pricing at around $20.68 per pound compared to $16.50 for November 2023. It was a similar story in lithium, with March 2025 contracts closing in October at $26.85 compared to $23.83 for the November 2023 contract (Figure 2).

Neither the steep decline in prices over the past 18 months nor the modest expectations for a recovery in prices over the coming 18-24 months have prevented either contract from seeing dramatic growth in aggregate OI. Indeed, OI has soared to nearly 10,000 contracts for lithium hydroxide and to around 20,000 for cobalt in recent months (Figure 3).

Part of the reason for the strong growth in OI may have to do with the needs of producer hedgers to manage their price risk. Both cobalt and lithium have seen explosive growth in global production in recent decades as well as strong increases in battery use. This is especially the case for lithium, whose mining production has grown 20-fold from 6,100 metric tons in 1994 to 130,000 by 2022 (Figure 4).

Much of this increased production has been directed to the battery sector. As recently as 2012 only 23% of lithium was used to make batteries. Today, its 80% (Figure 5).
