Copper — the pass-through clause decides who pays the record


MomentumX Consulting · 19 August 2026 · 9 min read

As copper sets records and the forecasts diverge, the pass-through arrives through supplier letters, and the contract clause decides who pays.

Copper reached a fresh United States record on 5 August 2026, the most-active Comex September contract touching $6.7045 a pound, equivalent to $14,781 a tonne. In London the three-month contract traded up to $14,050 a tonne, within reach of January's record of $14,500. The move itself will be widely reported. What happens to it inside a supply contract will not.

The exposure lands on Asia first. The region's electronics, machinery and cable manufacturers sit at the top of the copper chain, and the pass-through letters reach their buyers in the same quarter as the price move.

MomentumX works from that fact base through clause redesign, should-cost negotiation, implementation and value delivery.

The forecasts disagree, and the spread is the information

The price structure carries information that the headline figure does not. The LME cash contract has been settling at around a $65 a tonne premium to the three-month, the widest backwardation since January, which indicates physical tightness in the present rather than an expectation of tightness later. That distinction changes the economics of holding inventory, and with it what a supplier's stated lead time is actually worth.

Analyst opinion on the balance is divided, and the spread is more instructive than any single forecast. J.P. Morgan projects a refined copper deficit of 330,000 tonnes in 2026. The International Copper Study Group puts it at 150,000 tonnes. Goldman Sachs expects a near-term surplus. Three well-resourced houses are looking at the same mine schedules and reaching materially different conclusions, which suggests the uncertainty is real rather than a failure of one forecaster. Any procurement strategy resting on a single view of where the price goes next is resting on the least reliable input available.

The condition of supply is where the sources converge. Chile's output fell 9.04 per cent year on year in March 2026. Freeport-McMoRan has delayed the full restart of Grasberg in Indonesia from 2027 to 2028, although production there recovered from around 34,000 tonnes a day in April to approximately 69,000 tonnes a day in June. Benchmark Mineral Intelligence traced the Grasberg shock to the point at which the refined market tipped into deficit for 2026, and the disruptions since have been measured in years rather than quarters.

The smelting layer shows the strain most clearly. Treatment and refining charges reached minus $66.40 a tonne in the first quarter of 2026, which inverts the ordinary economics of the industry: smelters are paying miners for access to concentrate rather than being paid a fee to process it. Fastmarkets has described the resulting pressure across the global smelting industry, and the International Energy Agency has noted that record prices at the metal end coexist with mounting strategic pressure on the smelters in the middle. A processing layer operating at negative margin is not a stable foundation for supply.

For most companies the exposure sits in the products built from the metal rather than in the metal itself. Copper electric wire prices rose 5.30 per cent in the second quarter of 2026 and stood 18.42 per cent higher year on year, with the Associated Builders and Contractors putting the cumulative increase since February 2020 at 83.7 per cent. Further down the chain, copper and grain-oriented electrical steel together account for 50 to 55 per cent of a transformer's total production cost, and prices from the major equipment manufacturers rose between 45 and 95 per cent between 2019 and 2026 depending on model and specification.

Comex touched US$14,781 a tonne on 5 August with LME cash about US$65 a tonne over the three-month, and treatment charges at minus US$66.40 a tonne have smelters paying miners for concentrate.

A price only matters when it meets a contract

Every source above describes a price. None describes what happens when that price meets a contract, and that is where the outcome is decided for a buyer who has never touched the metal.

Two decades on the buy side at Disney, Nike, Unilever and Procter & Gamble produced the same observation in every commodity-linked category, with a consistency that suggests something structural. Suppliers raise price promptly and precisely when the input moves up, and reduce it slowly, partially, and only when asked, when it moves down. That is the predictable outcome of a contract leaving the pass-through to be negotiated case by case, in which the party holding the information also chooses when to raise the subject, and it requires no bad faith on anyone's part.

The clause that exists is often worse than useful, and this is the part that surprises people. Where an index provision names only the commodity — copper, rather than the LME cash settlement on a stated publication date over a stated reference window, applied to a stated material content per unit — it performs no better in practice than no clause at all. Every element determining the size of the adjustment is left open at the moment the adjustment is claimed, which is precisely when the buyer has least leverage and least time. A file full of such clauses reads as protection and delivers none.

The portfolio work adds a point about where the exposure is filed. Across the 729 companies held by 47 Asian private-equity firms that we mapped this year, around a hundred sit in electronics, automotive components, industrial manufacturing, energy and utilities, data centres and telecommunications, or construction — businesses carrying material copper content in what they buy. In most of them it is not filed under raw materials at all. It arrives inside a wiring harness, a cable run, a motor, a switchgear assembly or a building contract, which means the category owner watching the copper price and the category owner holding the exposure are usually different people.

Running the index monitor across twenty-five public cost-driver series makes the timing problem visible in a way a single check does not. Copper is one of the better-instrumented series available, with settlements published daily and a deep history. The difficulty is never finding the number. It is that the contract does not say which number, on which day, applied to how much metal.

A 15 per cent pass-through claim, taken apart

The arithmetic that settles a pass-through claim is short, and it is the reason a supplier's request and a buyer's exposure are rarely the same figure.

A supplier of a distribution transformer asks for a 15 per cent increase, citing copper. Copper and grain-oriented electrical steel together account for 50 to 55 per cent of that unit's production cost, and copper alone is roughly 30 per cent of it. Copper wire is 18.42 per cent higher year on year. The increase the input move actually justifies is 30 per cent of 18.42 per cent, which is 5.5 per cent. The remaining 9.5 per cent is a commercial ask wearing a commodity argument, and it will hold unless somebody does that multiplication.

Doing it properly is what a Rate-Anchored Should-Cost™ is for: building the delivered price from its objective components — material content at a published settlement, conversion, freight, tooling amortisation, margin — so that each element traces to a rate rather than to a negotiating instinct. Once the metal share of a cable run, a harness or a transformer is established, a request for 15 per cent on a 30 per cent metal content becomes a conversation with a defined answer.

The build is only as strong as the references behind it, and in a market where three major houses disagree about direction, the reference has to be one the supplier will also accept. The MomentumX Benchmark Basis™ holds those references cited and dated — LME and Comex settlements, the ICSG balance, published treatment and refining charge assessments, industry price indices — so that a should-cost position survives a technical challenge rather than merely opening a negotiation.

The same arithmetic runs backwards, and that is the half most organisations never claim. Where copper fell between two reset dates and the contract carried no reversal mechanism, the reduction was due and was not taken. In a portfolio of commodity-linked agreements the unclaimed downside is frequently larger than the disputed upside, because nobody raises it.

The first step is rewriting the clause, not negotiating the price

A buyer with commodity-linked exposure should stop negotiating the price and rewrite the clause. A usable index provision names six things: the settlement source, the publication date, the reference window, the material content per unit, the reset cadence, and symmetry — the same mechanism applying downwards as upwards, without either party having to ask. Rewriting that clause is worth more over a contract's life than any single price negotiation conducted under it, and it can be done at renewal without a tender.

The argument against comes from the supplier side and is not frivolous. Symmetry is the provision suppliers resist hardest, because a smaller manufacturer cannot hedge its own input and is being asked to accept a mechanism that removes the margin cushion it relies on when the market turns. Push it too hard and the risk is priced back in as a higher base, which leaves the buyer paying a permanent premium to avoid an occasional dispute. A formula also caps the buyer: where the market falls sharply, a negotiated outcome might have gone further than the index would allow. And there is administrative cost, since a clause nobody tracks is a clause nobody enforces.

The pricing-back point is correct and it sets the boundary of the recommendation. This work belongs in the agreements large enough to carry it, where the metal share is material and the contract has years left to run. Applying it across a tail of small suppliers buys disputes rather than value.

The cap objection deserves a straight concession. A formula does give up the occasional windfall from a well-timed negotiation in a falling market. What it buys in exchange is that the downside is taken every time rather than the few times somebody thinks to ask, and across a cycle the automatic mechanism collects more than the opportunistic one.

MomentumX can take the work through the full cycle. It starts with the clause inventory and the should-cost build. It ends with rewritten index mechanics and the recovery, in both directions, verified in the accounts.

What this means for APAC leadership teams

For enterprises, the near-term work is an inventory of which supply agreements carry a specified index mechanism and which carry none, followed by a should-cost view of the metal share on the largest exposed items. Most organisations find the exposure filed somewhere other than raw materials.

For consulting firms, direct materials is where general practices most often need specialist depth at short notice, and MomentumX works behind those engagements as a delivery partner while the client relationship remains with the firm.

For private-equity sponsors, a copper move of this size lands directly on gross margin in industrial, electrical and construction-adjacent assets, and the same missing clause typically repeats across the portfolio, which makes it one of the few operational fixes executable once and applicable many times.

The management challenge is constant. When the metal moves, does the contract say who pays, and does anyone claim the move back down?
