Copper buyers rarely lose money by misreading the market. They lose it because the hedge did not match the business behind it: a tonnage that shrank, a premium that moved, a margin call that arrived in the wrong month. Futures, options and fixed-price supply contracts are all useful tools, but each carries assumptions about volume, timing and cash. Get those assumptions wrong and a sensible hedge turns into an expensive surprise.

Hedging a number you are not certain of

The metal a fabricator needs is rarely a clean, fixed tonnage. Orders get cancelled, product mix shifts, scrap recovery varies and customers push delivery dates. Hedge 100% of a forecast and you have converted a commercial uncertainty into a financial obligation. If volumes fall, you are left holding a long futures position you have to close, booking a loss that no sales margin ever earned.

The workable approach is to layer the hedge against certainty. Firm, priced orders can be hedged in full. Forecast volumes can be hedged in tranches — perhaps a third when the enquiry book looks solid, more as purchase orders land — so the position grows with visibility rather than in one confident block.

Set a variance trigger

Decide in advance what happens when actual consumption drifts from plan. A simple rule works: if the hedged volume is more than about a tenth above or below expected usage, the position gets reviewed and trimmed. Without a trigger, nobody touches it until the discrepancy is too large to fix cheaply.

Ignoring basis, grade and currency

LME copper is a reference price, not your invoice. Between the two sit the physical premium or discount, scrap discounts, treatment and refining charges on concentrate, delivery terms, and the lag between pricing date and settlement. A cable maker may buy on a monthly average, pay a premium that resets quarterly, and sell in sterling while the exchange price is quoted in dollars.

If you hedge the exchange price and nothing else, you have swapped one risk for another. A flat copper market can still damage your margin if the premium widens or sterling strengthens. Map the invoice line by line and ask which components you can actually hedge and which you are accepting. Where a supplier will fix the premium, take it. Where the basis is genuinely volatile, a back-to-back arrangement with a merchant or producer is often better value than a paper hedge that only covers part of the exposure.

Choosing the instrument before defining the objective

The familiar tool is not always the right one. Ask what you are protecting — a margin, a tender price, a budget — and over what window. Then compare:

• Futures: fix the price completely, with daily variation margin and no upside if the market falls. Best for firm, dated requirements where cash headroom exists.
• Options: pay a known premium for protection while keeping the benefit of lower prices. Useful when volumes are uncertain, because the maximum cost is fixed at the outset.
• Collars: cheap or free protection funded by selling a put. That put obliges you to buy at the strike if prices fall, so the protection is real but the benefit is capped.
• Fixed-price supply contracts: simple and margin-free, but the supplier builds in a risk premium and often a volume tolerance. Compare the delivered price against a floating supply deal plus your own hedge.
• Average-price swaps: match monthly or quarterly average pricing, which suits buyers whose invoices are struck on averages rather than on a single day.

Underestimating margin and cash flow

Variation margin is real money moved daily, and it tends to be demanded when trading is difficult. A hedge that is economically correct can still break a business if it drains working capital in a weak quarter. Before committing, model a sharp adverse move and check whether the cash would still be there — and whether your bank would still be comfortable.

Size the hedge against committed facilities rather than the budget. Keep unencumbered headroom, agree who can call whom and how quickly, and consider options where the premium is known and paid up front rather than futures where the calls are open-ended. Document credit lines before you need them; arranging them mid-squeeze is expensive.

No written policy, and no line between hedging and trading

A written treasury policy is the cheapest control a metal buyer can buy. It should state which exposures are hedged, target hedge ratios, permitted instruments, maximum tenor, counterparty limits, approval levels, and how performance is judged — against the price achieved on the physical purchase, not against a view on the market.

Without that discipline, positions get adjusted because someone has an opinion, losses are rolled forward rather than acknowledged, and the hedge book quietly becomes a trading book. Documentation also matters for accounting. Hedge accounting rules require documented relationships and effectiveness testing; skip them and you can find fair-value swings landing in profit and loss while the physical cost sits somewhere else entirely. Speak to your accountant before you trade, not after.

Forgetting to roll and review

Hedges that expire before the metal is priced leave you exposed again, and rolling costs money in a contango market. Match expiry to your pricing dates and diarise the roll. Review the book on a fixed schedule — monthly is enough for most industrial buyers — rather than only when the copper price makes the news. Ask three questions each time: does the hedge still match the exposure, is the counterparty still sound, and has anything changed in the policy assumptions?

A practical checklist

Before the next hedge goes on, run through this:

1. Separate firm orders from forecast, and hedge each differently.
2. Reconcile the hedge to the invoice: premium, discount, grade, Incoterms, pricing window and currency.
3. Confirm the instrument matches the objective, including volume flexibility.
4. Stress-test the cash impact of a sharp price move in both directions.
5. Check counterparty exposure, credit lines and documentation.
6. Record the rationale, the accounting treatment and the approval.
7. Diarise the roll and the monthly review.
8. Measure the result against the physical price achieved, not against the market.

None of this requires a market view, and that is the point. Hedging is about making the price of copper predictable enough to run the rest of the business. This is general guidance rather than financial advice, so for anything material to your balance sheet, take advice from a broker, treasurer or accountant who knows your position.
