Working capital in a commodity trading company refers to the funds required to finance the day-to-day operations of physical commodity transactions — specifically, the capital needed to cover the gap between paying a supplier and collecting payment from a buyer. Without adequate working capital — whether from equity or from bank credit facilities — a commodity trading company cannot physically execute trades, regardless of how attractive the commercial opportunity appears.
Working capital for a commodity trading company is defined as current assets minus current liabilities, where current assets include physical inventory, receivables from buyers, and cash, and current liabilities include amounts owed to suppliers, banks, and other short-term creditors. The working capital cycle describes how funds flow through each stage of a trade and return to the starting point after settlement.
The Working Capital Cycle in Physical Commodity Trade
The working capital cycle in physical commodity trading begins when a trader agrees to buy a cargo and ends when the buyer pays. In between, the trader deploys capital at each stage: paying the supplier at origin, funding freight and logistics costs, financing the cargo in transit, and waiting for the buyer to pay after delivery and inspection.
For example, assume a trading company agrees to buy 5,000 metric tons of copper cathode from a Chilean supplier at assume $46 million total and sell it to a Chinese rod mill at assume $46.5 million. The sequence of capital flows is: on day 1, the trader opens a Letter of Credit (LC) in favor of the Chilean supplier, backed by the trader's bank credit facility — the bank's commitment creates a contingent liability; on day 15, the cargo is loaded and the supplier presents documents, triggering payment of $46 million from the bank to the supplier; the trader's credit facility is drawn by $46 million; from day 15 to day 45, the cargo is in transit and the trader carries a $46 million drawn balance on their credit facility; on day 50, the cargo arrives and is accepted by the Chinese rod mill; on day 80, the rod mill pays $46.5 million; on day 80, the trader repays the $46 million bank draw, and retains $500,000 as gross margin before financing costs.
During the 65-day period from LC opening to final payment, the trader has $46 million of capital deployed. Even at a modest interest rate of assume 6% per annum, the financing cost for 65 days is approximately $492,000 — nearly equal to the gross margin. The trader's net margin after financing, bank charges, freight, and inspection is much smaller, illustrating why working capital efficiency is commercially critical.
Why Working Capital Constrains Trade Volume
The reason working capital constrains trade volume is that a company can only have as many simultaneous positions as its available capital — equity plus credit facilities — can support. A company with $10 million of equity and a $30 million revolving credit facility has a maximum working capital deployment of $40 million. If each trade requires $5 million of average deployed capital for 60 days, the company can run approximately 8 simultaneous trades at any point.
As a trading company grows — executing more trades, in larger volumes, across longer supply chains — its working capital requirement grows proportionally. Companies that outgrow their capital base relative to their trading volume face a working capital crisis: they cannot fund the next purchase without collecting from an outstanding sale.
Efficient working capital management therefore involves minimizing the time between paying the supplier and collecting from the buyer, selecting buyers who pay promptly, using usance LCs or open account terms carefully to avoid carrying receivables for too long, and sizing credit facilities to match trading ambitions.
Working capital is not an abstract financial concept in commodity trading — it is the physical constraint that determines how large a company can trade, how fast it can grow, and whether it can sustain a sequence of transactions without running out of funds between payment and collection.
