Inside the Metal Markets: How Trading, Hedging and Relationships Shape the Flow of the World's Most Critical Commodities

Former Trafigura trader Samuel Basi explains how producers lock in margins, why traders still matter, and the practical mechanics of futures, premiums and risk management that every mining company needs to understand.

In the intricate global system that moves copper from Chilean mines to Chinese factories, aluminum from smelters to automotive plants, and silver into solar panels, one function remains indispensable: the connection between those who produce metal and those who consume it. That connection is rarely seamless. It requires financing, logistics, risk management, and—above all—relationships. Few people understand the machinery of this system better than Samuel Basi, a former Trafigura metals trader who spent more than a decade at one of the world’s largest commodity houses before building a derivatives book at a niche firm and later writing the practical guide Perfectly Hedged.In a wide-ranging discussion, Basi offered a masterclass in how metal trading actually works—from the ground to the exchange, from concentrates to scrap, and from the simple act of locking in a margin to the complex decisions that determine whether a mining company survives price volatility. For Canadian producers, investors, and anyone involved in the resource sector, the lessons are both educational and immediately relevant.

The Many Faces of Metal Trading

Metal trading is not a single activity. It encompasses refined metals (the high-purity cathodes, ingots, and bars that manufacturers use), concentrates (the upgraded ore shipped from mines to smelters), scrap (an increasingly vital source as the energy transition accelerates), precious metals, and a range of minor and ferrous metals that often lack deep futures markets.

Volume tells two different stories. In physical tons consumed, iron ore and steel dominate. On the major exchanges—the London Metal Exchange (LME), the CME, and the Shanghai Futures Exchange—copper and aluminum generate the greatest liquidity and trading activity. These base metals are the workhorses of global industry and the most straightforward to hedge. Minor metals such as cobalt and lithium, critical for batteries, trade in far smaller volumes and often lack the same liquid futures markets, demanding specialized knowledge and higher risk tolerance.

Geography remains decisive. Chile and Peru dominate copper mine supply. China is both the largest producer and by far the largest consumer of most industrial metals, drawing in flows from South America, Australia, Africa, and elsewhere. Canada, the United States, Russia, and Australia rank among the significant producers across multiple metals. Increasingly, Africa is being developed as a new source. Global flows, however, are no longer frictionless. Tariffs, sanctions, and a turn toward resource nationalism have redirected traditional routes and elevated the strategic value of secure, reliable supply chains.

Why Traders Exist

Producers such as the major mining houses can and do sell directly to end users. Yet traders persist for clear commercial reasons. They offer financing and credit terms that many producers prefer not to extend and that many consumers cannot easily obtain elsewhere. They provide logistical expertise that allows a mine to sell material free-on-board or into a local warehouse rather than managing ocean freight, insurance, and delivery to a distant factory. Most importantly, they maintain diversified networks of homes for different grades and specifications—networks that few individual producers can match on a global scale.

The largest trading houses—Trafigura and Glencore among them—operate at a scale that requires substantial capital, global infrastructure, and the ability to move high volumes at thin margins. Smaller and mid-sized traders survive by carving out niches: specific grades, scrap, less liquid metals, or counterparties that larger firms find less attractive from a credit or volume perspective. In every case, the backbone of the business is relationships. Trust, face time, and a proven ability to perform under pressure determine who gets the call when a producer has excess material or a consumer needs metal urgently.

The Mechanics of Hedging: Becoming Price Agnostic

For mining companies, the most practical lesson from Basi’s experience concerns hedging. The purpose of a hedge is not to predict the market. It is to remove price uncertainty so that a producer can lock in a margin against a known cost of production.

Consider a simplified example. A producer with an all-in cost of $8,000 per tonne sells a futures contract at $10,000 per tonne for delivery in several months. At that moment, a $2,000 gross margin is secured. If the physical price later falls to $7,000, the producer sells the metal at the lower price but buys back the futures at the same level, generating a $3,000 gain on the futures that offsets the physical shortfall. The net result remains the original $2,000 margin. If prices rise instead, the producer forgoes the additional upside—but has protected the business against the risk of prices collapsing below the cost of production.

Traders who choose to remain fully hedged operate on the same principle. They buy physical metal and simultaneously sell an equivalent quantity of futures (or the reverse). When the physical sale is priced, they close the futures position. Price movements cancel out, leaving the trader with the premium, discount, or treatment charge differential that constitutes their commercial margin, after logistics and financing costs.

The major exchanges make this possible. On the LME, futures can theoretically be traded years forward, though liquidity concentrates in the first three months. Most futures positions are closed or rolled rather than taken to physical delivery; fewer than five percent result in actual metal moving into or out of exchange warehouses. Yet the possibility of delivery keeps the paper market anchored to the physical one.

Options provide another layer. A call or put gives the right, but not the obligation, to buy or sell at a predetermined price. The cost is the premium paid for that flexibility—essentially insurance that preserves upside while limiting downside. Not every company uses options, but they form part of the toolkit for those willing to pay for selective exposure.

Grades, Premiums, and the Details That Matter

Not all metal is equal. Exchange contracts specify high-purity benchmarks—special high-grade zinc at 99.995 percent, P1020 aluminum, and equivalent standards for copper and other metals. Many consumers, however, can accept lower grades or require specific value-added forms. The differences appear in the premiums or discounts to the exchange price. Scrap markets introduce still greater variability and often higher volatility. Concentrates trade on treatment and refining charges (TC/RCs)—effectively the fee the smelter charges to process the material into refined metal.

These differentials are where many physical traders earn their living. Matching the right grade to the right home, blending parcels to meet payable thresholds, or securing long-term offtake agreements that give producers volume certainty are all part of the commercial craft.

Demand Drivers and the Energy Transition

Looking forward, the demand trajectory for most base metals and battery materials remains upward. Copper, aluminum, nickel, zinc, lithium, and cobalt are embedded in electrification, renewable energy infrastructure, and electric vehicles. Lead faces potential pressure as lead-acid batteries give way to newer chemistries, but the broader complex is supported by the same structural forces that have drawn oil traders into metals desks. Precious metals, particularly silver, benefit from both investment demand and industrial applications such as solar.

Stimulus in major consuming economies, infrastructure programs, and manufacturing recovery tend to be bullish for metals. The reverse is also true. For Canadian producers sitting on significant copper, nickel, and other resources, understanding these demand dynamics—and managing the associated price risk—is central to long-term value creation.

Practical Takeaways for Mining Companies

Basi’s experience points to several enduring principles. 

First, hedging is a tool for certainty, not speculation. Companies that treat it as a core risk-management discipline rather than an occasional tactical decision are better positioned to withstand volatility. 

Second, relationships and logistical capability still matter more than pure price discovery. 

Third, the energy transition is expanding the set of metals that matter and increasing the strategic premium on secure supply.

The metal markets remain one of the purest expressions of global trade: physical material moving from where it is mined to where it is transformed, financed and risk-managed at every step. For those who produce the metal, understanding how that system works is no longer optional. It is a competitive necessity.
