Aluminium has given back most of the premium it built since the shock earlier this year, copper and tin are still trading well above where they started, and lead sits close to flat, which means a desk running a consolidated position across all four metals is now working from a genuinely different set of numbers than it was reconciling in June.
LME aluminium climbed to a four-year high of around $3,800 a tonne in early June, driven by disruption to Middle East shipping routes following the conflict with Iran, then fell back to around $3,170 by late July, giving up nearly all of the premium it had built since the shock. Current levels sit around $3,255.80 (Sept 2026, spot indication tracking LME, USD per metric tonne), which leaves the metal only slightly above its July low and well short of its June peak.
A desk that priced margin against the June high and one that priced it against the July low were carrying two very different metals risk positions on the same metal, within the same quarter.
Copper’s January move was sharper than a single number suggests. The metal passed $13,000 a tonne for the first time in history in early January, then spiked to an intraday record of $14,527.50 on 29 January, the largest single-day move since 2008, before reversing the same day to close at $13,720.50 and falling further after. It broke that record in the week of 7 September, touching a fresh all-time high of more than $14,850 a tonne, before pulling back to $14,014.50 (16 Sept 2026, spot indication tracking LME, USD per metric tonne) as warehouse stocks rose.
Tin has followed copper’s direction rather than aluminium’s, surging into the mid-$50,000s a tonne in May on continued supply tightness, with flows from Myanmar still running below pre-disruption levels.
Close to flat, for entirely different reasons.
Lead is trading close to $1,900 a tonne (Sept 2026, spot indication tracking LME, USD per metric tonne), slightly below where it stood a year ago, with analysts expecting it to hover near $2,000 into 2027. Aluminium’s move traces directly to the Middle East supply shock, while copper and tin were already at record levels before it began and have stayed elevated since. Lead’s fundamentals, driven more by battery demand and Chinese secondary production than by Middle East shipping routes, have kept it moving on a separate path from the rest of the complex.
LME contracts settle on daily prompt dates out to three months, then weekly out to six months, then monthly beyond that, and any position that falls between those published dates needs an interpolated price, always an approximation, to be valued at all. A book holding aluminium, copper, tin, and lead is tracking four prompt-date calendars, each moving through its own daily-to-weekly-to-monthly structure at its own pace, and each metal’s current divergence, aluminium reversing, copper and tin still elevated, lead flat, has to be priced against the right point on the right curve for the right metal.
Where that is a manual calculation rather than a live one, a trader assessing exposure today is working from a picture that may already be several prompt dates out of date by the time it reaches them.
LME average daily volume reached 756,996 lots in 2025, up 8% on 2024, which was itself up 18.4% on the year before, so the divergence across metals is playing out on an exchange that handles more volume every year. That matters because the cost of a manual, once-a-day consolidated position compounds against a larger and faster-growing base with each year it persists.

Metals risk management is the process of tracking and pricing exposure across metals positions, typically futures, options, and OTC contracts, as prices move. For a desk running multiple metals at once, that means consolidating positions from different venues and pricing conventions into one current view, rather than reconciling each metal separately at the end of the day.
LME contracts settle on daily prompt dates out to three months, then weekly out to six months, then monthly beyond that, and any position that falls between those published dates needs an interpolated price, always an approximation, to be valued at all.

A metals CTRM is a commodity trading and risk management platform built to handle the specific mechanics of metals trading, prompt-date settlement, interpolated pricing for non-standard tenors, and averaging contracts, alongside standard futures, options, and OTC positions, all in one consolidated view rather than several disconnected systems that each need reconciling on their own.
Different commodities settle differently. Some products track a single forward curve, others like LME metals settle across multiple prompt dates in the same instrument. Commodity risk management has to account for whichever structure applies, which is why a platform built for one commodity type doesn’t always translate cleanly to another.
