Key Takeaways 82% confidence
- A peer-reviewed study in Environmental Science and Ecotechnology models cobalt supply risk across 230 countries and finds the network of indirect exposure is about four times denser than the physical trade network.
- The researchers describe the global cobalt supply chain as "robust-yet-fragile," with China and the United States showing particularly high systemic fragility despite their different roles in the chain.
- About 45% of electric vehicles built today still rely on cobalt-containing battery chemistries, NMC (nickel manganese cobalt) or NCA (nickel cobalt aluminum), rather than cobalt-free alternatives.
- An estimated 94% of global cobalt output is a byproduct of copper and nickel mining — roughly 50% from copper mines and 44% from nickel mines — with only about 6% coming from mines dedicated to cobalt.
- Chinese companies own or finance an estimated 15 of the 17 largest cobalt mining operations in the Democratic Republic of the Congo, which alone supplies an estimated 70-75% of the world's mined cobalt.
- Tesla and BYD have both shifted meaningful production toward cobalt-free lithium iron phosphate (LFP) batteries since 2020, a hedge against exactly the kind of concentrated supply risk the study describes.
A new academic study modeling 230 countries finds cobalt supply shocks cascade far beyond direct trade links, a structural risk that matters because about 45% of EVs still use cobalt-containing batteries and the Democratic Republic of the Congo supplies most of the world's cobalt.
Analysis 82% confidence
Most supply-risk conversations about cobalt start and end with one number: the roughly 70-75% of global mine output that comes from the Democratic Republic of the Congo. That figure is real, but a new academic study argues it understates the actual risk, because it only counts direct trade relationships. Researchers from the Chinese Academy of Sciences, Peking University and the University of Southern Denmark built a multilayer network model spanning 230 countries and six supply-chain stages — mining, refining, manufacturing, use and recycling — and used two decades of trade-flow data to trace how a disruption at any single node could propagate outward. Their result, published in Environmental Science and Ecotechnology, is that the full web of indirect exposure is close to four times as dense as the map of direct trade links alone. A refinery outage in one country, in other words, can still hit a battery plant on the other side of the world even if the two never traded a gram of cobalt directly, because they share exposure through common intermediate suppliers further up the chain.
The study's language for this is "robust-yet-fragile" — the system shrugs off small, routine disruptions the way any diversified network would, but a shock landing on a concentrated node, whether a dominant mining region or a bottleneck refinery, can cascade well past its origin. That distinction matters for where policymakers and buyers look for risk. The researchers found refining and manufacturing bottlenecks contribute meaningfully to fragility, not just the mining end of the chain that usually gets the attention. China and the United States both showed up as points of particularly high systemic fragility in the model, despite occupying very different positions in the supply chain — China concentrated in refining and battery manufacturing, the US more exposed as a downstream consumer with thin domestic processing capacity.
The underlying concentration the study is modeling is stark on its own terms. An estimated 94% of the world's cobalt is produced as a byproduct of mining a different metal entirely — about 50% alongside copper, 44% alongside nickel — leaving only around 6% from operations mined for cobalt specifically. That byproduct structure means cobalt supply doesn't respond cleanly to cobalt prices the way a standalone commodity would; a copper or nickel miner's own economics, not cobalt demand, largely decides how much cobalt reaches the market. Layered on top of that is ownership concentration: an estimated 15 of the 17 largest cobalt mining operations in the DRC are owned or financed by Chinese companies, a position built up over roughly two decades through China's outward investment strategy in African mining and processing assets.
The demand side offers a partial, not total, offset. Roughly 45% of electric vehicles built today still use cobalt-containing battery chemistries — nickel manganese cobalt (NMC) or nickel cobalt aluminum (NCA) — prized for their energy density despite the exposure they carry. Tesla and BYD have both leaned into cobalt-free lithium iron phosphate (LFP) chemistry since 2020, with BYD's "Blade" battery a prominent example, precisely because LFP sidesteps this supply risk entirely. That shift is real, but it is gradual, model-by-model, and nowhere close to eliminating cobalt from the EV supply chain — which is exactly why a network-level shock, and not just a price move, is still the risk this study is trying to measure.
Why This Matters 78% confidence
Buyers and battery makers who track cobalt risk by counting direct suppliers are, according to this study, undercounting their actual exposure by roughly a factor of four — a mine or refinery disruption two or three steps removed in the chain can still reach them. With almost half of today's EVs still built on cobalt chemistries and the DRC's mine ownership concentrated in Chinese hands, that hidden exposure sits directly underneath the battery supply chains automakers and their suppliers are counting on.
Price Impact
The study is a structural risk analysis based on historical trade-flow data (1998-2019), not a report of a current supply disruption or price move, so it carries no immediate, direct price signal. Its findings point to elevated tail risk — a future shock could cascade further than direct trade data suggests — which is a modest bullish factor for risk premium over time, balanced against the bearish, multi-year drag from continued EV industry adoption of cobalt-free LFP chemistry.

Fundamental Analysis
Demand Drivers 75% confidence
About 45% of EVs manufactured today still use cobalt-containing NMC or NCA battery chemistries, prized for higher energy density, which keeps a meaningful share of global EV demand tied to cobalt supply even as some automakers shift toward cobalt-free LFP cells.
Supply Drivers 78% confidence
An estimated 94% of global cobalt output is a byproduct of copper (about 50%) and nickel (about 44%) mining rather than dedicated cobalt mining, meaning cobalt supply is largely set by copper and nickel miners' own production decisions rather than by cobalt demand or price on its own.
Geopolitical Risks 75% confidence
An estimated 15 of the 17 largest cobalt mining operations in the Democratic Republic of the Congo are owned or financed by Chinese companies, concentrating not just where cobalt is mined but who controls it — a legacy of China's outward investment strategy in African mining assets over roughly the past two decades.
Mining Production 74% confidence
The Democratic Republic of the Congo supplies an estimated 70-75% of the world's mined cobalt, and the study's network model finds that concentration, combined with cobalt's status as a byproduct metal, makes the mining stage a key node where a disruption can cascade into refining and manufacturing well beyond direct trade partners.
Refinery Output 68% confidence
The study identifies refining and manufacturing bottlenecks, not just mine-level supply concentration, as meaningful contributors to systemic fragility, with China showing particularly high fragility in the model given its concentrated position in global cobalt refining and battery manufacturing.
Country Impact 74% confidence
| Country | Impact | Reason |
|---|---|---|
| Democratic Republic of the Congo | High | Supplies an estimated 70-75% of the world's mined cobalt, making it the single most consequential node in the network the study models, with roughly 15 of its 17 largest mines owned or financed by Chinese companies. — The study identifies concentrated mining regions like the DRC as exactly the kind of node where a shock can cascade well beyond direct trading partners. |
| China | High | Owns or finances most of the DRC's largest cobalt mines and holds a concentrated position in global cobalt refining and battery manufacturing, which the study's model flags as a point of particularly high systemic fragility. — An estimated 15 of the DRC's 17 largest cobalt mining operations are owned or financed by Chinese companies. |
| United States | Medium | The study's model flags the US as another point of high systemic fragility, reflecting its downstream exposure as a major consumer of cobalt-containing batteries with limited domestic mining or refining capacity. — The study's network analysis found the US, despite a different supply-chain role than China, showed comparably high systemic fragility. |
Industry Impact 70% confidence
| Industry | Effect | Reason |
|---|---|---|
| Electric Vehicles | Negative | About 45% of EVs built today still use cobalt-containing NMC or NCA battery chemistries, leaving a meaningful share of EV production exposed to a supply chain the study finds is more interconnected — and more vulnerable to cascading shocks — than direct trade data alone would suggest. |
| Mining | Negative | Cobalt's status as a byproduct of copper and nickel mining, combined with heavy concentration in the DRC, means the mining industry's cobalt output is structurally exposed to disruptions at a small number of dominant, often Chinese-owned, operations. |

Market Sentiment
Bullish Factors 55% confidence
- Byproduct-driven supply (94% of output tied to copper and nickel mining decisions) limits how quickly new dedicated cobalt supply can respond even to sustained price increases, a structural support for prices during any future shock.
Bearish Factors 58% confidence
- Tesla and BYD have both expanded cobalt-free LFP battery production since 2020, and continued adoption of LFP chemistry across the EV industry would gradually shrink the share of vehicles exposed to cobalt supply risk at all.
- The study's own scope is historical and structural (trade flows from 1998-2019) rather than a signal of an active, current disruption, so it does not by itself point to any near-term price catalyst.
Alternative Scenarios 55% confidence
- If EV makers continue shifting toward cobalt-free LFP chemistry at the pace Tesla and BYD have shown since 2020, the share of global EV production exposed to cobalt supply risk could shrink meaningfully over the next several years.
- If a shock does hit a concentrated node such as DRC mining or Chinese refining capacity, the study's model suggests the resulting disruption could spread further and faster than a simple count of direct trading partners would predict.
Who Benefits, Who Loses
| Party | Stance | Reason |
|---|---|---|
| EV makers with cobalt-free battery lines, such as Tesla and BYD's LFP production | Bullish | Cobalt-free LFP chemistry sidesteps the concentrated, cascading supply risk the study describes entirely, insulating that share of production from a DRC- or China-centered shock. |
| Automakers and battery makers still reliant on NMC or NCA cobalt chemistries | Bearish | The roughly 45% of EV production still built on cobalt-containing chemistries carries the full network exposure the study describes, including risk that travels through indirect supply-chain links the companies themselves may not even be tracking. |
Investor Watchlist 65% confidence
Educational items to monitor — not investment advice.
- The pace of EV industry adoption of cobalt-free LFP battery chemistry versus NMC/NCA cobalt chemistries
- Any disruption at a concentrated node the study flags as high-risk, particularly DRC mining operations or Chinese cobalt refining capacity
- Further academic or industry research applying this network-risk framework to other critical minerals with similarly concentrated supply chains
Price Risks 58% confidence
- A shock at a concentrated node such as DRC mining or Chinese refining capacity could, per the study's model, cascade into price pressure across supply chains with no direct trading relationship to the disrupted source.
- Continued EV industry adoption of cobalt-free LFP chemistry is a gradual, multi-year trend that could reduce cobalt's price sensitivity to EV demand over time, though it has not offset cobalt's byproduct-driven supply constraints so far.
