S&P Critical Mineral Market Reports: Structural Costs Explained

The Broken Price Signal: Why Critical Minerals Cannot Function Like Ordinary Commodities

Commodity markets are supposed to be self-correcting. When prices rise, capital flows toward new production. When prices fall, marginal producers exit. Supply and demand equilibrate over time, guided by the invisible hand of transparent price signals. For most raw materials, this mechanism works reasonably well. S&P critical mineral market reports have begun to illuminate just how thoroughly this mechanism has broken down for a specific class of strategically vital materials.

The failure is not incidental. It is structural. Markets for materials like gallium, germanium, tungsten, and neodymium-praseodymium oxide are thin by volume, geographically concentrated at the processing and refining stage, and systematically exposed to non-market interventions that distort price discovery before private investors can act on it. The result is a class of materials that are simultaneously indispensable to modern technology and effectively unfinanceable through conventional capital markets.

Understanding why this matters, and what is being done to fix it, requires engaging with a new body of independent market analysis that has the potential to reshape how Western governments and investors approach the critical minerals demand surge challenge.

What Makes Critical Mineral Markets Structurally Different

The Thin Market Problem and Its Investment Consequences

Unlike iron ore or copper, which trade in high volumes across multiple exchanges with deep secondary markets, critical minerals are exchanged in relatively small quantities, often through bilateral contracts negotiated privately between producers and end-users. This thinness creates a fundamental problem: there is insufficient transactional data to generate reliable reference prices.

Without credible reference prices, the entire investment ecosystem seizes up. Lenders cannot model downside scenarios with confidence. Equity investors cannot price risk against a stable revenue baseline. Project developers cannot secure offtake agreements on commercially viable terms. Consequently, governments cannot calibrate policy responses to a market they cannot accurately observe.

This opacity is not merely inconvenient. It is strategically exploitable. When price formation is opaque and trading is thin, a dominant producer with the ability to influence export volumes, domestic subsidies, or stockpiling decisions can effectively set global prices without participating in any formal market mechanism.

How Geographic Concentration Becomes a Pricing Weapon

The degree of concentration across critical mineral supply chains is extraordinary by any historical comparison. Consider the following breakdown:

These figures are not static snapshots. They represent decades of deliberate industrial policy that systematically built downstream processing capacity in China while keeping upstream mining assets dispersed globally. The result is that even when ore is mined outside China, it frequently cannot be refined without passing through Chinese facilities.

Furthermore, gallium in semiconductors illustrates this dynamic with particular clarity. China's December 2024 export restrictions on gallium to the United States produced an almost immediate price bifurcation: domestic Chinese gallium traded at approximately $300 per kilogram while prices outside China surged to roughly $2,100 per kilogram, a differential of approximately seven times. No freely functioning market produces a price gap of that magnitude. It is the signature of deliberate supply control.

What the S&P Critical Mineral Market Reports Actually Measure

From Spot Prices to Structural Costs: A Critical Distinction

In response to this analytical vacuum, S&P Global has published a series of draft critical mineral market reports covering five materials: antimony, gallium, germanium, neodymium-praseodymium oxide, and tungsten. The reports are notable not for what they predict, but for what they measure.

The central analytical concept introduced in the S&P critical mineral market reports is the structural cost, a metric that differs fundamentally from spot price assessments or short-term forecasts. A structural cost represents the full economic threshold required for a production asset to achieve its targeted return on investment over the long term, incorporating capital recovery, operating expenses, and all other costs needed to sustain viable production at scale.

A structural cost is not what the market is paying today. It is the price the market must be willing to pay over time if new supply outside dominant geographies is ever going to get built, financed, and operated profitably.

This distinction carries enormous policy weight. Spot prices in critical mineral markets are frequently suppressed below structural cost thresholds by state-subsidised competitors, making economically rational projects appear financially unviable. The S&P reports attempt to cut through that distortion by anchoring analysis to long-run economic reality rather than short-run market noise.

The Bottom-Up, Asset-Level Methodology

The analytical rigour underpinning the S&P critical mineral market reports derives from a bottom-up, asset-level approach that is meaningfully different from aggregate market modelling. Rather than extrapolating from historical price series or top-down trade data, S&P Global constructs its cost estimates by working from individual projects upward.

The methodology incorporates:

1. Direct engagement with producers, processors, and off-takers across the supply chain
2. Company-level financial and operational analysis of active and announced projects
3. Proprietary market intelligence covering cost structures, capital intensity, and production timelines
4. Asset-level capacity modelling that maps each project's contribution to total supply at varying price levels
5. Structural cost curve construction that ranks assets from lowest to highest cost, revealing supply availability at any given price threshold

This produces what is known in commodity economics as a cost curve, a ranked visualisation of production assets that shows how much supply becomes economically viable at each price level.

Mineral-by-Mineral: Structural Costs and Supply Realities

Gallium: When Near-Total Concentration Meets Export Controls

With approximately 99% of global primary low-purity gallium production located in China, the gallium market offers the most extreme case study in how supply concentration translates into pricing leverage. The December 2024 export restriction produced the price bifurcation described above, but the longer-term implications extend further. Gallium is a critical input for compound semiconductors used in 5G infrastructure, satellite communications, and radar systems, meaning that price volatility in gallium directly affects the economics of entire technology supply chains.

S&P Structural Cost Estimates for Gallium:

A critical and underappreciated technical detail: most gallium is recovered as a trace by-product of aluminium refining from bauxite, meaning that gallium production is inherently constrained by the economics and location of the primary aluminium industry. Expanding ex-China gallium supply is therefore not simply a matter of building refineries. It requires either co-locating recovery infrastructure with existing aluminium smelters or developing entirely new recovery pathways from alternative feedstocks such as zinc processing residues or coal fly ash.

Germanium: By-Product Economics and the Processing Bottleneck

Germanium's supply chain dependency is structurally similar to gallium's in one important respect: it is predominantly recovered as a by-product of other industrial processes, primarily zinc smelting and, in China, the processing of coal combustion residuals. This by-product dependency fundamentally limits where germanium production can be economically established.

China controls more than 90% of global germanium refining capacity. Germanium is used in fibre optic cables, infrared optics, and photovoltaic cells, applications where there are currently no commercially viable substitutes.

S&P Structural Cost Estimates for Germanium:

The gap between the full structural cost ($2,100–$2,300/kg) and the sustaining cost ($830–$910/kg) is the starkest in the group, reflecting the exceptional capital intensity of establishing germanium refining capacity from scratch outside existing infrastructure.

NdPr Oxide: The Permanent Magnet Supply Chain's Chokepoint

Neodymium-praseodymium oxide is the foundational input for sintered neodymium-iron-boron (NdFeB) permanent magnets, the high-performance magnet type used in electric vehicle traction motors, direct-drive wind turbines, and precision-guided munitions. China's approximately 84% share of global NdPr supply means its leverage extends well into the manufacturing economics of the entire clean energy and defence sectors. For broader context on how these dynamics affect critical minerals and energy security, the implications are significant.

S&P Structural Cost Estimates for NdPr Oxide:

A rarely discussed technical complexity in the NdPr market is the cracking problem: rare earth ore concentrates must be chemically separated through either hydrochloric acid or sulphuric acid leach processes, generating radioactive thorium and uranium by-products that require licensed disposal pathways. The challenges inherent in rare earth supply chains extend well beyond simple extraction, encompassing these significant regulatory and environmental burdens that have historically deterred investment outside China.

Tungsten: A Dual-Use Metal Hiding in Plain Sight

Tungsten receives less public attention than rare earths or gallium, but its strategic profile is formidable. It is the metal with the highest melting point of any element at 3,422 degrees Celsius, making it irreplaceable in cutting tools, drill bits, armour-piercing penetrators, and high-temperature aerospace components. Ammonium paratungstate, the primary intermediate product that feeds global tungsten supply chains, is subject to approximately 85% Chinese refining dominance.

Antimony: The Defence-Critical Dual-Source Risk

Antimony is distinctive within this group because its supply chain concentration involves two geopolitical risks rather than one. Chinese and Russian-controlled operations together dominate global antimony mining and smelting, creating a scenario where Western defence supply chains are exposed to disruption from either source independently. The antimony shortage risks extend across flame retardants in military electronics, primer compounds in ammunition, and components in night-vision technology.

Its relatively low structural cost compared to the other four minerals reflects less capital-intensive smelting infrastructure, but does not diminish its strategic criticality.

The Policy Architecture Being Built Around These Benchmarks

The Agreement on Trade in Critical Minerals and Border-Adjusted Price Floors

The S&P critical mineral market reports are not being produced in isolation. They are designed to feed directly into the design of the Agreement on Trade in Critical Minerals (ATCM), a trade framework under development by the U.S. Trade Representative's office in coordination with allied trading partners.

The ATCM concept envisions mineral-specific, phased-in price floors applied at the border, calibrated to structural cost benchmarks so that economically viable production in participating nations cannot be undercut by artificially suppressed imports. U.S. Trade Representative Jamison Greer has described the structural cost benchmarks as a step toward establishing border-adjusted price floors, correcting market distortions, and building supply chain resilience.

Treasury Secretary Scott Bessent has similarly emphasised that transparent, market-based pricing is a prerequisite for attracting the private capital needed to construct secure and diversified mineral supply chains. The logic is straightforward: if a price floor is set at or above the structural cost benchmark for a given mineral, investors can model project economics against a policy-supported revenue floor rather than a volatile spot price susceptible to state-sponsored manipulation.

FORGE: Multilateral Coordination Beyond Trade Policy

Running in parallel with ATCM negotiations is the U.S. Forum on Resource Geostrategic Engagement, known as FORGE, launched at the Critical Minerals Ministerial convened in Washington in February 2026. FORGE provides a broader coordination platform among allied nations beyond any single trade agreement.

FORGE Coalition Overview:

Together, the ATCM's price floor mechanism, the FORGE multilateral framework, and a growing network of bilateral critical mineral agreements are assembling the policy architecture for an allied critical minerals ecosystem. The S&P critical mineral market reports contribute the analytical infrastructure — specifically the structural cost benchmarks — that such an architecture requires to function credibly.

What Structural Cost Benchmarks Mean for Investors

Reassessing Project Economics Under a Price Floor Regime

For investors evaluating critical mineral projects outside China, the structural cost benchmarks provide a reference framework that has not previously existed in this form. A project whose all-in production cost falls within or below the structural cost range has a reasonable basis for economic viability under a price floor regime.

Key investment considerations emerging from the reports:

• The explicit inclusion of capital recovery in full structural cost estimates means the benchmarks account for the cost of building new supply, not merely operating it — a distinction that matters enormously for project financing
• The gap between full structural cost and sustaining cost identifies the capital recovery burden that policy mechanisms must address to unlock initial investment
• Project timelines anchored to 2028 make near-term development decisions particularly significant for investors seeking to position ahead of potential price floor implementation
• The sustaining cost figures provide a secondary viability benchmark for assessing operational economics once a project has been commissioned and capital has been recovered

Why Private Capital Has Historically Stayed Away

The structural cost framework also illuminates, with unusual analytical precision, why private capital has historically been reluctant to commit to critical mineral development outside dominant supply chains. The barriers are well-defined:

• Spot prices can be suppressed below production cost by state-subsidised competitors with long time horizons and no requirement to generate commercial returns
• Thin secondary market liquidity makes price risk hedging difficult or effectively impossible for most project developers
• Development timelines of seven to fifteen years create extended exposure to policy shifts, technology change, and price risk before production revenue materialises
• The absence of credible independent reference prices prevents lenders from modelling downside scenarios with the confidence required to commit project finance

The S&P critical mineral market reports address the last of these barriers directly. By establishing credible, methodology-transparent structural cost benchmarks, the reports create the reference price infrastructure that lenders and equity investors have lacked. Whether that is sufficient to unlock private capital at scale depends on the parallel progress of ATCM negotiations and FORGE coordination. However, it is a genuinely necessary condition, and one that has not previously existed in this form.
