The Trader Had One Client. The Client Stopped Trading.
Quote from chief_editor on June 10, 2026, 5:30 pmPhysical commodity brokers and small traders who depend on one or two clients for the majority of their volume discover the concentration risk when that client leaves or fails.
A physical commodity broker had built a business over eight years around a primary client — a mid-sized European metals trading company that used the broker's network for sourcing specific grades of recycled aluminum from Eastern Europe. The broker's annual commission income was approximately $280,000, of which roughly $210,000 came from the single client relationship.
The client was acquired by a larger trading group. The acquiring company had its own sourcing network for the same commodity, with its own established relationships in Eastern Europe. Within six months of the acquisition, the client instructed the broker that their sourcing arrangements were being consolidated into the parent company's existing supplier relationships. The broker's services would no longer be required.
The broker had no contractual protection — no minimum commission arrangement, no exclusivity, no notice period beyond what their brokerage agreement specified, which was 30 days. The relationship that had produced $210,000 per year for eight years ended on 30 days' notice.
A Relationship Is Not a Contract Unless It Is a Contract
The broker in this case had built a business around a commercial relationship that was real, productive, and long-running, but that was not contractually protected against the commercial decisions of the client. When the client's circumstances changed — through acquisition — the relationship terminated legally and cleanly, with the minimum notice required by the brokerage agreement.
Long-term commodity brokerage relationships create an expectation of continuity that is commercially reasonable but not legally enforceable unless the relationship is governed by a contract that creates enforceable continuity obligations. A client who has used the same broker for eight years has no legal obligation to continue doing so for year nine. The relationship history creates goodwill but not legal rights.
For commodity brokers and trading intermediaries who build their business around key relationships, the concentration risk is structural: if one or two clients represent more than half of revenue, the failure or departure of any one of them is an existential threat to the business. Managing this risk requires either: diversifying the client base (so no single client represents more than 20 to 25% of revenue), negotiating contractual protections that require notice periods, minimum volumes, or compensation for early termination, or building proprietary capabilities — sourcing networks, market knowledge, physical trading infrastructure — that reduce dependence on the transactional relationship with any specific client.
Industry estimates for revenue concentration in physical commodity brokerage suggest that single-client dependency above 50% of revenue is common among smaller brokerage operations that grow organically from a single relationship. The concentration is sustainable as long as the client relationship is stable — and fragile the moment the client's circumstances change.
The Direct Trade Problem
Beyond client departure through acquisition or business change, commodity brokers face a second structural risk: the client they introduced learns enough about the underlying supply network to trade directly, without the broker. This is particularly acute in physical commodity brokerage where the broker's value is their knowledge of specific suppliers — once the client knows the suppliers, the broker's informational edge is gone.
Brokers who protect against direct circumvention do so through: non-circumvention clauses in brokerage mandates (which protect against direct trading with specifically introduced parties for a defined period), building broader networks so that any specific introduction represents a smaller portion of total value, and continuously developing new sourcing relationships that the client has not yet been introduced to.
Non-circumvention clauses protect for the period they cover but create commercial friction in relationships. Clients who want flexibility resist long non-circumvention periods. The negotiation of these terms — at the time the brokerage mandate is signed, when both parties are focused on the commercial opportunity rather than the exit scenario — is where the protection is established or forfeited.
