Cobalt is a metal with two stories. The first is told on a chart: sharp climbs, sudden falls and investors trying to read the next cycle. The second begins in the ground, in the work of the people who mine and process it, and ends inside the devices and vehicles that shape contemporary life.
The price fell. Its strategic importance did not.
To understand blue gold, we have to read both stories together. A rising price may bring investment without bringing prosperity to the community at the source. A falling price may make a mineral look less important just as its supply chain becomes more exposed. The market measures a kilogram; the century must measure what that kilogram makes possible.
The price of progress is not a straight line
Consider the recent cycle. Indicative reference levels were around US$26 per kilogram in 2016, surged above US$95 at the 2018 peak, retreated near US$26 in 2019, then approached US$82 in the 2022 battery boom. By 2024, oversupply had pushed the market towards US$25. These are approximate metal-market reference points at different moments, not comparable annual averages, nor prices for ore or an individual contract.
That movement is why the homepage calls cobalt a metal measured in volatility. Supply expansion, battery chemistry, policy and demand can pull the price in different directions. The chart below gives the historical rhythm; it cannot predict the next quote.
The story did not stop in 2024. The IEA’s 2026 outlook says cobalt prices rose by around 130% amid restrictions on exports from the Democratic Republic of the Congo. A short-term surplus can become a very different market when policy changes the available flow.
The country at the centre
The Democratic Republic of the Congo sits at the heart of cobalt supply. Its resources create strategic influence, but they also raise questions about working conditions, traceability, ownership and how much of the value remains close to where the mineral is produced.
The phrase “blue gold” should hold those questions in view. Manufacturers, traders and investors cannot treat provenance as a decorative note added after the transaction. Credible oversight and local value creation are part of a resilient supply chain.
Africa’s mineral wealth deserves a story that goes beyond extraction. Processing capacity, infrastructure, skills and commercial participation could allow producing countries to capture more of the value in the finished technologies.
What changes with the battery
Cobalt contributes to certain high-performance lithium-ion battery chemistries and remains relevant to aerospace superalloys and specialist industry. Yet technology never stands still. The rise of lithium iron phosphate batteries reduces cobalt use in many vehicles. Nickel-cobalt-manganese designs continue to evolve, while recycling may reclaim more material already in circulation.
That makes any single demand forecast provisional. The IEA’s 2025 outlook projected cobalt demand growth of roughly 50–60% to 2040. Its 2026 outlook says the longer-term demand projection has moderated with faster LFP adoption, while warning that the projected 2035 supply gap has widened to over 25% under its base-case project pipeline and stated-policies assumptions.
A projection is a scenario, not a promise. The investable question is whether responsible mines, refineries and recycling networks can adapt to changing chemistry and changing policy without leaving producing communities behind.
A more valuable definition of value
A battery arrives sealed and beautifully engineered. Its origins are less visible. The distance between source and finished product makes the supply chain feel like somebody else’s concern. It is everyone’s concern if technology is to earn the language of progress.
The long view of cobalt is not a simple wager on a higher price per kilogram. It is a test of resilient supply, verifiable provenance and the ability of resource-rich nations to move further along the value chain.
Blue gold is measured in volatility. Its lasting worth will be measured by what survives those swings: trust, capacity and a fairer share of the future for the people closest to its source.
