A commodity broker is an intermediary who facilitates transactions between buyers and sellers of physical commodities without taking title to the goods. A broker's function is to identify a counterparty for a principal — bringing a buyer to a seller or a seller to a buyer — and earn a commission for that introduction and facilitation service. The broker does not own the commodity at any point, does not bear price risk, and is not a party to the final supply contract.
The difference between a broker and a trader in commodity markets is that the trader takes ownership of the physical commodity and bears the associated price, logistics, and credit risk, while the broker remains outside the transaction and earns a fee for connecting the parties.
How a Commodity Broker Operates
A commodity broker's primary asset is market intelligence and a network of active buyers and sellers. A broker working in the metals market, for example, may know which smelters are looking for copper concentrate, which mines have excess production to place, what price levels are clearing in the market, and what shipping windows are available. This information, combined across many counterparties, allows the broker to efficiently match buyers with sellers.
Brokers earn a commission — also called brokerage — that is typically expressed as a percentage of the transaction value or a fixed amount per metric ton. In commodity markets, standard brokerage ranges widely depending on the commodity and transaction type. For large bulk commodity transactions — for example, a 50,000 metric ton cargo of thermal coal — brokerage might be agreed at assume $0.10 to $0.20 per metric ton, paid by one or both parties. For smaller or more complex transactions, brokerage rates are negotiated individually. Brokerage in oil markets is often expressed as a fixed number of cents per barrel.
The broker is paid only when a transaction closes. If a broker introduces a buyer to a seller and the parties fail to agree on terms, the broker earns nothing. This contingency structure motivates brokers to facilitate deals that are realistic, not merely possible.
For example, assume a nickel trading company in London is looking to buy 500 metric tons of nickel cathode for delivery in Rotterdam within the next 30 days. A specialist metals broker contacts a Norwegian refinery that has availability in that window and arranges a preliminary price discussion between the two parties. After negotiation, the parties agree on a price at London Metal Exchange (LME) Cash Settlement plus assume $95 per metric ton. The broker earns a brokerage commission — for example, assume $5 per metric ton — from one or both parties, settled separately from the main transaction.
The Boundaries of a Broker's Role
A broker does not guarantee the performance of either party. Once buyer and seller are connected and the contract is signed, the broker's role is effectively complete. If the seller fails to deliver or the buyer fails to pay, the broker is not liable — those risks are between the contracting parties.
Some brokers provide additional value by advising on market pricing, contract terms, or logistics options. Others operate as pure voice brokers — executing introductions with minimal advisory function. In energy markets, specialist voice brokers handle OTC (Over-the-Counter) derivatives transactions between financial and physical market participants, facilitating price discovery in markets that do not have centralized exchange trading.
Brokers must be transparent about their commission arrangements. In many markets, both parties are aware of and agree to the brokerage fee. Undisclosed commission — where a broker earns from both parties without each party knowing — can create conflicts of interest and, in some jurisdictions, legal exposure.
A commodity broker generates value by reducing the search cost for both buyers and sellers — the commission they earn reflects the time, network access, and market knowledge required to identify the right counterparty for a specific transaction.
