There are certain structural risks in metals trading that are easy to overlook precisely because it has become routine. At Loqsea, we have seen broken date forward positions calculated in spreadsheets, prompt dates entered manually at trade capture, and even net exposure aggregated by hand from three different systems each morning before the market opens.
None of these feel like risk and are often simply considered “workflow”. They have been part of the daily rhythm for long enough that the underlying gap they represent has become invisible.
But the gap is there, and in a market that just recorded its strongest year ever, with the LME reaching an average daily volume of 717,334 lots in 2025, up 7.9% on the previous year, and Q4 2025 setting an all-time record at 777,016 lots per day, Source: LME Data Highlights 2025, it is compounding.
Loqsea is connected to the London Metal Exchange as an ISV, listed on the LME’s ISV and connectivity providers page. As a CME Group ISV for EMEA, the same real-time capability extends to CME metals positions for firms managing cross-venue books. The Loqsea platform in relation to metals trading was designed specifically to address the three accuracy problems described in this article.
Most CTRM platforms were designed for monthly settlements. The LME market does not follow this standard convention, with daily settlement (or prompt dates in LME parlance) dates out to three months forward, weekly on the third Wednesday of the month out to six months, and monthly beyond that out to ten years for some contracts.
When one considers the array of spreads that this can create, one can see why a system that does not allow for this detailed data structure will lead to inaccuracies in a firm’s positions and P&L data.
This is the approximation problem. We cover it in full in our white paper alongside the broader infrastructure gaps that LME participants face.
Generic systems respond to this by approximating. They map positions to the nearest available settlement date, and this also impacts book valuations.
Most generic risk systems bundle all positions into a single monthly date rather than showing positions per prompt date. This means exposure across multiple prompt dates is not visible in its true form, and the detail is often reconstructed manually, typically in spreadsheets, each day.
The operational consequence is that a generic risk system may not accurately reflect the current market. In view of the fact that the daily workarounds are practised and familiar, the gap tends to stay invisible until it becomes a painful bottleneck.
Loqsea is built to reflect positions by prompt date from the point of trade capture removing the need for manual adjustment and reducing the risk of positional errors.
Some platforms hold futures, options, ETD, and OTC positions including LME averaging in separate modules, leaving the user to piece it together. When these instrument types live in separate systems or spreadsheets, net exposure is never a live number. It is often a calculation, produced by hand, from multiple sources.
A risk system that combines not only futures and options but also ETD and OTC including LME averaging provides a single, consolidated view of exposure. Without this, the gap tends to stay invisible until it matters.
The FCA’s March 2025 findings following the 2022 nickel crisis documented what this gap looks like at scale. By 2pm on 7 March 2022, LME Clear had called more than $7.4 billion in additional margin on the three-month nickel contract in a single day. Source: FCA Final Notice, March 2025. The gap between what firms’ systems showed and what the clearing house was seeing in real time was not a technology failure. It was the consequence of sub-optimal practices and a lack of real-time risk tools.
Loqsea combines futures, options, ETD, and OTC including LME averaging in a single platform, providing a consolidated and continuously updated view of net exposure.
When a system cannot interpolate the LME forward curve natively, it is not calculating your P&L, it is estimating it. The mark on a forward position may reflect where the market was yesterday, not where it is now. In a stable session, that difference may be small, but in a volatile market, it is not.
A forward contract settling on an illiquid date is often referenced to the nearest major liquidity point. Valuing it accurately requires interpolating the LME forward curve in real time. Most systems cannot do this natively, and so traders do it manually, in a spreadsheet, often against yesterday’s closes, while the market moves. This manual intervention can sometimes lead to errors, which may not be immediately evident.
The operational consequence is that a generic risk system may not accurately reflect the current market. In view of the fact that the daily workarounds are practised and familiar, the gap tends to be an accepted inaccuracy.
It is important to note that interpolation itself is an approximation, as LME curves do not always move in a linear manner. Loqsea holds the LME forward curve natively and interpolates it throughout the trading day using available data and defined conventions. All positions, whether third Wednesday dates or less liquid prompts, are valued using the data that is available, or interpolated within defined conventions when it is not. This removes the need for additional spreadsheet calculations and manual reconciliation, while recognising that the output remains an approximation rather than a precise calculation.
Precision in LME infrastructure is not just an operational question, it is a commercial one. The LME’s prompt date structure creates trading opportunities that are truly only accessible to desks whose real-time risk management systems can handle them quickly and accurately. A desk working from approximated data is at a disadvantage, as it is less agile and potentially has less confidence in its trading decisions.
With heightened volatility, the potential cost of approximation is growing.
