Trade in electrification metals has reorganized around a China-centered hub-and-spoke network whose concentration the paper links to greater pricing power.
Research question
How did the trade network for strategic electrification metals become concentrated, and what does network centrality imply for global prices?
Method & data
Bilateral trade data for thirteen electrification metals from 1995–2023 are combined with a stylized network model, text-based supply shocks, and local projections.
Main finding
The abstract reports that China’s centrality reflects processing investment and policy rather than reserves, and that supply contractions in critical metals have larger and more persistent consumer-price effects than comparable fossil-fuel shocks.
Why it matters
The green transition may replace hydrocarbon dependence with a different form of strategic exposure concentrated in mineral processing networks.
What to verify
The construction and validation of the text-based shocks and sensitivity to alternative network definitions are not stated in the public abstract.

Trade networks underpinning the energy transition are endogenous economic objects, and their structure is a source of market power. Using bilateral trade data for thirteen electrification metals over 1995–2023, we show that trade in these materials has reorganised into a hub-and-spoke system centred on China, in sharp contrast to the diffuse, multilateral structure of fossil fuels. This centrality did not follow from resource endowments: China holds few of the underlying reserves. It was built through processing investment, industrial policy, and commodity-targeted development finance—an equilibrium outcome rather than a geographical accident. We formalise this in a stylised model in which a country chooses how central to become, and show that centrality maps into pricing power: the world price response to a strategic supply cut is stronger when the network is more concentrated and downstream demand and fringe supply are more inelastic. Constructing text-based, commodity-specific supply shocks and estimating local projections, we find that supply contractions in critical metals raise US and EU consumer prices by roughly twice as much as comparable fossil-fuel shocks, and more persistently. Centrality is therefore not merely descriptive: it creates leverage over global prices. The green transition reduces strategic dependence on hydrocarbon exporters but reconstitutes it around mineral supply chains.
