Learn how to use London Metal Exchange (LME) futures to lock in prices, tame volatility, and protect your scrap trading margins with simple, practical hedging setups you can actually run in the real world.
Why LME futures matter for scrap traders
The London Metal Exchange is the key global reference market for industrial metals, with futures that allow producers, consumers and intermediaries to transfer price risk along the supply chain rather than carry it on their balance sheets.
Even though most scrap moves on physical contracts, prices for copper, aluminium and ferrous scrap are typically negotiated as a differential to LME benchmarks or related indices, which is why sharp swings on the screen rapidly feed through into your buy and sell levels.
By tying physical deals to the LME Official Settlement Price and taking offsetting futures positions, scrap processors, brokers and mills can stabilise margins while still allowing the market to discover the outright metal price.
How LME futures work in plain English
An LME futures contract is a binding agreement to buy or sell a standard quantity of a specific metal grade at a fixed price on a defined prompt date in the future.
LME contracts use a unique prompt-date structure, with daily dates out to three months, weekly dates out to six months and monthly dates much further forward, giving traders flexibility to mirror the timing of physical shipments and storage.
Most hedgers close out futures positions before delivery by taking an equal and opposite trade, so that only the cash profit or loss versus the physical price remains, while exchange margining and clearing reduce counterparty credit risk.
In addition to physically settled futures, the LME lists cash-settled contracts such as LME Steel Scrap CFR Turkey that settle against price-reporting agency indices, allowing scrap participants to hedge price exposure without moving metal through LME warehouses.
Core hedging setups for scrap traders
1. Short hedge – protect inventory value
A short hedge is used when you hold or expect to hold physical metal and fear prices will fall, so you sell futures now to offset potential downside in your stock or forward sales.
Scrap processors, yards and exporters commonly short LME or scrap futures against yard inventory or purchase contracts, then close the futures when they complete the sale so that losses on one side are offset by gains on the other.
2. Long hedge – secure future supply costs
A long hedge is used when you expect to buy metal in future and worry that prices will rise, so you buy futures now to lock in a maximum effective cost for the volume you plan to consume.
Steel mills, foundries and manufacturers often buy LME or scrap futures against a percentage of their forecasted scrap needs, then unwind or roll hedges as physical purchasing programs are executed.
3. Back-to-back hedging for traders
Scrap traders frequently hedge both sides of a deal, going long futures when committing to buy material from a supplier and taking an offsetting short futures position when fixing the sale to an end customer, effectively locking in a trading margin between the two.
This approach turns outright price risk into basis and execution risk, allowing trading houses to scale volumes while keeping exposure aligned with their risk appetite and credit lines.
4. Cross-hedging scrap with LME benchmarks
Because not every scrap grade has a perfect futures contract, many participants “cross-hedge” by using a related LME benchmark, such as hedging copper scrap against LME copper cathode futures or regional ferrous scrap against LME Steel Scrap CFR Turkey.
Cross-hedging reduces risk but introduces basis risk, since your scrap price will not move one-for-one with the chosen LME contract, so the hedge ratio and contract choice must be tuned to historic correlations and commercial reality.
Step-by-step: locking in a scrap trading margin
Imagine a broker agreeing today to buy 500 tonnes of shredded steel scrap for shipment next month, with the supplier pricing the deal at a discount to the LME Steel Scrap CFR Turkey index at that future date, leaving the broker exposed to a potential price drop before securing an outlet.
- The broker estimates that 500 tonnes of physical exposure equates to five futures contracts and sells that number of LME scrap futures for next month at the current screen price, creating a short hedge against the incoming stock.
- If the market falls by the time the cargo is sold, the physical sale price to the mill will be lower, but gains on the short futures position will offset the weaker physical realisation, largely preserving the originally targeted margin.
- If prices rise instead, the broker may earn more on the physical sale but lose on the futures, again leaving the overall outcome close to the planned spread, which is the core objective of a hedge.
- Once the sale is completed and pricing finalised, the broker buys back the futures to close the hedge, so that only the combined, hedged cash result on the trade remains.
The same logic can be flipped for mills or foundries by buying futures when signing fixed-price contracts for finished products, so that they are not forced to absorb unfavourable spikes in input scrap costs over the life of those agreements.
Practical risk checklist before you hedge
- Match volume and tenor: Align contract size and prompt dates with realistic shipment schedules and weight estimates to avoid being unintentionally over- or under-hedged.
- Understand basis risk: Know how your specific scrap grade and location typically trade relative to the chosen LME or index benchmark so you can calibrate hedge ratios and margins.
- Monitor margin and liquidity: LME positions are margined daily, so limits, cash buffers and access to liquid contract months must be in place before building sizeable hedges.
- Separate hedging from speculation: A structured hedge programme should be tied to physical purchase and sales plans rather than directional bets on where metal prices will go next.
- Work with experienced brokers: Access to specialised LME brokers and clear internal policies on approvals, reports and limits materially reduces operational and execution risk.
Scrap trader FAQs on LME hedging
Is LME hedging only for large mills and banks?
No, the LME was designed for the physical metals industry, and many mid-sized scrap processors and traders use broker-cleared accounts to run modest, tightly linked hedges rather than large speculative books.
What if my scrap grade doesn't have its own futures contract?
In that case, you can consider cross-hedging against the closest liquid LME or scrap benchmark and manage the remaining basis risk through pricing formulas, discounts and regular hedge reviews.
How far forward can I hedge scrap exposure on the LME?
LME futures trade on a rolling set of prompt dates extending from the near-dated daily structure to monthly settlements many months or even years ahead, though liquidity tends to concentrate in the nearer months used most actively by the physical market.
Does an LME hedge guarantee I won't lose money?
A well-structured hedge is designed to stabilise margins around a planned level, not to maximise profit, so you can still lose money if volumes, timing or basis move against you or if the physical deal itself is mispriced.
