DRC Quota Regime Tightens Grip on Global Cobalt Supply
Since July 2026, the Democratic Republic of Congo (DRC) has enforced quarterly export quotas on cobalt hydroxide, cutting exports by an estimated 18% year-to-date. The DRC, which accounts for over 70% of global cobalt production, has set a Q4 quota of 22,000 tonnes, down from 28,000 tonnes in Q3. This policy aims to capture more value domestically but has tightened availability of battery-grade hydroxide (minimum 20.5% Co) for international buyers.
Chinese Refiners Build Stockpiles, Diverting Material
Chinese refiners, controlling over 75% of global cobalt refining capacity, have increased stockpiles of battery-grade hydroxide by 25% since June 2026, according to industry data. This strategic build has diverted material from the spot market, exacerbating the premium. As a result, the spread between battery-grade (20.5% Co) and standard-grade (10% Co) hydroxide has widened to $4,200/t, up from $2,800/t a year ago. The premium now represents 22% of the underlying standard-grade price, which is trading at $19,200/t.
Battery Makers Face Margin Pressure; Substitution Risks Emerge
The record premium is hiking input costs for lithium-ion battery producers, particularly those in South Korea and Japan. With cobalt comprising roughly 15% of a typical NMC cathode, the $4,200/t premium adds about $630 per tonne to cathode costs, squeezing margins. Some automakers are accelerating research into alternative chemistries, but near-term substitution is limited due to performance requirements. The premium is expected to persist through 2027 unless DRC quotas are relaxed or Chinese stockpiling slows.
Market Implications: Volatility Ahead
The cobalt hydroxide market is now highly sensitive to policy shifts and stockpile data. Traders are watching for any indication of a quota review or changes in Chinese buying patterns. A potential risk is that high prices could trigger demand destruction, particularly if battery makers shift to LFP, which contains no cobalt. However, with electric vehicle sales growing at 20% annually, near-term demand remains robust, keeping the premium supported.
