Commodity

• 1. Introduction

  ›

  Commodity sits at the heart of every economy on earth. A barrel of crude oil drilled in Texas and a barrel drilled in Saudi Arabia sell for the same price on the same market. The buyer never asks who pumped it. That indifference is the whole point. Karl Marx captured the idea precisely: "From the taste of wheat, it is not possible to tell who produced it, a Russian serf, a French peasant or an English capitalist." The grain is the grain. That single quality, fungibility, is what separates a commodity from everything else traded in the world. What makes something fungible rather than distinctive? How do goods cross the line from premium product to bulk resource? And what happens to the people whose labour produces these interchangeable things? Those are the questions this documentary will pursue.

• 2. A Word Five Centuries Old

  ›

  English speakers first used the word commodity in the 15th century, borrowing it from the French commodité, which carried the meaning of amenity and convenience. The French term came from the Latin commoditas, a word for suitability, convenience, and advantage. Behind that stood commodus, the Latin root also responsible for commodious and accommodate. It meant appropriate, proper measure or condition, and benefit. What began as a word for general usefulness gradually narrowed into a precise economic term. By the time Alfred Marshall published his Principles of Economics in 1920 and Léon Walras published Elements of Pure Economics, commodity had become the standard label for any economic good or service available for purchase. The word's journey mirrors the slow crystallization of market thinking itself.

• 3. Hard, Soft, and Electric

  ›

  Economists divide commodities into broad families based on how they come into being. Soft commodities are grown: wheat and rice belong here, goods that follow the rhythms of soil and season. Hard commodities are mined from the earth, and gold, silver, helium, and oil fall into this category. Energy commodities, which include coal, gas, and electricity, form their own distinct group. Electricity carries a property that sets it apart from every other commodity: it is usually uneconomical to store, so it must be consumed at the very moment it is produced. That single constraint shapes entire power grids and pricing structures. Iron ore, sugar, grains, chemicals, and computer memory all qualify as commodities in the broader sense. Popular trading examples include crude oil, corn, and gold, three goods whose prices ripple through nearly every other market on the planet.

• 4. Where Prices Are Made

  ›

  Commodity exchanges are the places where fungibility becomes financial reality. The Chicago Board of Trade, the London Metal Exchange, and the New York Mercantile Exchange are among the best-known venues where buyers and sellers meet. Other exchanges span every continent: the Dalian Commodity Exchange in China, Bursa Malaysia Derivatives, the Multi Commodity Exchange in India, and Bourse Africa, formerly known as GBOT, among others. On any of these floors, what defines a commodity is not the specific producer's product but the underlying standard written into the contract. These markets respond quickly to shifts in supply and demand, moving toward an equilibrium price with notable efficiency. Pension funds and sovereign wealth funds allocate capital to commodities and commodity-related infrastructure partly to diversify investments and partly to guard against the inflationary erosion of currency values. Investors who do not trade directly can gain exposure through a commodity price index.

• 5. The Commoditization Trap

  ›

  Commoditization is the process by which goods that once commanded premium prices lose their distinctiveness and collapse into the bulk market. Generic pharmaceuticals and DRAM chips are two well-documented examples of goods that once carried premium margins and then became commodities as the knowledge required to produce them spread across the industry. A New York Times article cited multivitamin supplements as a clear case: a 50 mg tablet of calcium delivers equal value to a consumer regardless of which company made it, so multivitamins now sell in bulk at any supermarket with little brand differentiation. Nanomaterials are described in the source as moving through a similar transition. Yet commoditization is not a binary switch. Few products are completely undifferentiable, and even electricity can be distinguished by its generation method in markets where buyers can choose renewable sources and pay more for them. For milk, eggs, and notebook paper, many customers treat the goods as fungible and price becomes the only deciding factor. Others weigh organic certification, cage-free standards, recycled content, or Forest Stewardship Council certification, and those distinctions restore a measure of differentiation.

• 6. Marx, Ricardo, and the Value Question

  ›

  Karl Marx built his analysis of the commodity on a debate that had preoccupied economists for generations before him. Adam Smith argued that exchange value was composed of rent, profit, labour, and the costs of wear and tear on farming tools. David Ricardo, working from Smith's foundation, pushed the argument further by claiming that labour alone constitutes the content of exchange value in any good or service. Ricardo also observed something troubling: only part of the exchange value of a commodity was paid back to the worker who made it. The remainder, unpaid labour, was retained by the owner of the means of production, meaning the site, the raw materials, and the machines. In a capitalist system, that retained value flows to the capitalist as rent or profit. Marx accepted Ricardo's labour-centred view but identified a flaw in how earlier economists measured it. A skilled worker finishes a commodity faster than an unskilled one, so a strict "quantity of labour" measure would paradoxically make the slower, unskilled worker's output more valuable. Marx resolved this by introducing the concept of socially necessary labour time, the average time that society as a whole requires to produce a given commodity. That average, not the time of any individual worker, was for Marx the correct basis for exchange value. Karl Rodbertus-Jagetzow was among the additional economists who weighed in on this long dispute, alongside Smith and Ricardo.

• 7. Super Cycles

  ›

  Roughly four times over the last 120 years, commodity prices as a whole have climbed well above their long-run averages and stayed there for roughly a decade. These episodes are called super cycles, and each has been driven by large shifts in industrial and commercial activity that demanded extraordinary quantities of raw materials. The first super cycle began in late 1890, fuelled by widespread industrialization across the United States and then accelerated by World War I. Prices peaked in 1917 and fell into a downtrend that lasted into the 1930s. A second cycle took hold as war returned to Europe in the late 1930s, with demand driven not only by the conflict itself but by the enormous rebuilding required across Europe and Asia in its aftermath. That cycle peaked in 1951 and faded in the early 1970s. A third cycle grew from the energy and resource demands of expanding world economies during the 1970s, ending when foreign investment retreated as extractive industries were nationalized. The fourth and most recent cycle began in 2000, when China joined the World Trade Organization. Chinese urbanization and industrialization accelerated, drawing workers into cities and creating vast new demand for raw materials. The Great Recession of 2008 broke that cycle as GDP figures fell across the world. A possible fifth super cycle was anticipated as the COVID-19 pandemic wound down and governments began building large-scale clean energy infrastructure.
