Demand-chain power

Demand-chain power is John Coyne's term for leverage derived from organising the buying side of a market: the capacity of a large or coordinated purchaser to influence prices, investment decisions and the distribution of value across an industry. Coyne introduced the term in a June 2026 article for the Australian Strategic Policy Institute. It is a proposed analytical concept, not an official legal category or a demonstrated finding about every concentrated market.

Origin

Coyne developed the concept from China's iron ore purchasing. Australia's assumption had been that economic power flowed from geology: ownership of a resource the world's largest steel producer could not easily source elsewhere. The China Mineral Resources Group (CMRG), a state entity created to coordinate Chinese iron ore procurement, challenged that assumption by centralising negotiations, shaping pricing mechanisms, and strengthening the bargaining position of Chinese steelmakers; by mid-2026 senior executives at BHP and Fortescue were publicly suggesting the balance of power had shifted. Coyne's generalisation: while Australia spent years of policy effort on supply-chain security, China was steadily and quietly strengthening its ability to shape demand itself.

Mechanism

Demand-chain power operates through monopsony and coordination. A fragmented seller base facing a single organised buyer loses pricing power even where the underlying resource is scarce; the buyer influences where capital flows, which projects proceed, and who captures value along the chain. The power is quiet by design: no export is banned and no tariff imposed, so the instrument leaves none of the legal or diplomatic signature that supply-side coercion generates, while still disciplining sellers who depend on the buyer's market. Coyne's deeper point is systemic: commodities are not products but systems of producers, customers, financiers, logistics providers, exchanges, and regulators, and influence over the system, rather than ownership of the resource, determines where value accumulates. The greatest leverage often sits downstream, in refining, financing, standards, and end-user demand, not at the mine.

Application and implications

The concept reframes coercion cases in which China used its position as a dominant customer rather than supplier. The China's trade restrictions on Australia and alleged economic coercion (2020-2024) campaign included restrictions affecting coal, wine, barley and lobster, though the legal form, official explanation and effect differed by product. For statecraft planning, the concept extends dependency mapping to customer concentration. A dominant buyer may impose market-access coercion without an export control, but market concentration alone does not establish coercive intent.

The concept also qualifies weaponised interdependence theory, whose best-known hubs are supply-side. A hub-and-spoke topology can form around organised demand as well as a monopoly input. The empirical test is whether purchasers actually coordinate, possess credible switching options and change seller behaviour. Ordinary bargaining should not be relabelled coercion without evidence of state linkage, a demanded change in conduct and a credible connection between access and compliance.
