The London Metal Exchange (LME), the world’s main market for industrial metals, is exploring tokenization of metal held in its Hong Kong warehouses, so that the stock could be pledged as collateral for loans. The plan was first reported by Reuters in an exclusive on 28 October 2026, citing three people with knowledge of the matter. The exchange itself has said only one thing on the record: that it is “at the early stages of exploring the tokenisation of off-warrant metal inventories” to support financing.
That is the whole of the official position. The LME has named no blockchain, no partner, no metal and no launch date, and it has not issued a press release that we could find. Nothing has been tokenized. Some crypto headlines since Wednesday have said the exchange already “tokenizes” its reserves; the reporting does not support that.
What is new is who is looking. The LME, owned by Hong Kong Exchanges and Clearing (HKEX) since 2012, sets the benchmark prices for copper, aluminium, nickel and zinc used by miners, smelters and manufacturers around the world. A tokenization project there would bring the idea of on-chain real-world assets into one of the oldest corners of commodity trading, and the first concrete step is modest: an invitation-only roundtable with the industry in early November.
What the LME said, and what the three sources added
According to the Reuters report, as carried by Euronext’s news service and The Standard in Hong Kong, the LME wants to turn metal stored in its Hong Kong warehouses into digital assets that can be used for financing, for example as collateral for a loan. The three sources said this could draw investors, traders and financiers to the city and give the exchange a new source of revenue. Those are the sources’ words, not the exchange’s.
The LME’s statement to Reuters is shorter and more careful. Beyond the “early stages” line, it said it would engage with stakeholders as it formulates its plans. No written plan has been made public; the exchange says it will draw one up with the market.
Only off-warrant metal is in scope
The idea covers one specific smart contract holding reserves of two or more tokens, supplied by users, that a decentralized exchange uses to execute trades automatically at a price set by a formula.">pool of metal. On the LME, a warrant is the title document for a lot of metal sitting in an approved warehouse. Metal on warrant can already be traded, delivered against a futures contract or used to secure a loan, because the warrant proves who owns it. That metal is excluded from the tokenization idea, according to the sources.
Off-warrant metal is different. It sits in the same warehouses but has no warrant attached, often because its owner does not want it available for delivery on the exchange. Since 2020 the LME has required warehouses to report these off-warrant stocks, to give the market a fuller picture of supply of metals such as copper and aluminium. But, as Reuters put it, there is no standardised way to finance that metal. A token, in this reading, would play the role a warrant plays for on-warrant stock: a record of who owns which metal, which a lender could accept as security.
Which metals would be covered is not stated. Copper and aluminium appear in the Reuters text only when it describes the off-warrant reporting rules, not as candidates for tokens. Separately, the sources said the LME is looking at relaxing its Hong Kong rules so that aluminium can be stored outdoors, something it tried briefly in the 1990s and stopped because of weather damage and security concerns. That item is not presented as part of the token idea.
LME tokenization: what is still unknown
For readers used to crypto announcements, the list of missing details is long. None of the reports we read answers any of these points:
- Which blockchain or platform would record the tokens, and whether it would be public or permissioned.
- Who would issue the tokens and who would hold the metal on behalf of token holders.
- Which metals would be eligible, and in what volumes.
- Who could hold or use the tokens: only banks and trading houses, or a wider group.
- What a token would legally be: a claim on a specific lot, a warehouse receipt, or something else.
- Which regulator would oversee it. No source mentions the UK Financial Conduct Authority, the Bank of England, the Hong Kong Securities and Futures Commission or the Hong Kong Monetary Authority.
- Whether the push comes from the LME alone, from HKEX, or from the Hong Kong government, and when anything would launch.
The size of the pool is also unclear. Off-warrant metal “is reported to subscribers only”, according to the GoldFix newsletter, so we have no public figure for Hong Kong. For metal on warrant, GoldFix, citing the LME’s warehouse data, counted 6,664 tonnes in Hong Kong at the end of September, all held by a single warehouse company and equal to about half a percent of total LME stocks. No source gives a target size for any token scheme.
Why Hong Kong, and why now
The sources tie the idea to Hong Kong’s ambitions as a commodity centre, and the dates line up. The LME approved Hong Kong as a delivery location in January 2025, despite concerns about high warehouse rents in the city. In March 2026, Beijing’s 15th five-year plan backed Hong Kong as a commodity trading hub explicitly, for the first time, according to Reuters. In September, Hong Kong’s own five-year blueprint said the city would use its status as an approved LME delivery point to grow commodities trading, risk management and financing.
Financing is the word that links the blueprint to the token idea. LME chief executive Matt Chamberlain mentioned tokenisation in a speech at LME Week Asia in May 2026, according to Reuters; we could not find the speech itself. Its parent company is running its own experiments: HKEX is testing how to turn carbon credits into tokens so that trades settle in seconds rather than days, the same report said.

The roundtable falls in the same week as Hong Kong FinTech Week, from 2 to 6 November. No source links the two, and the LME has not said where or exactly when its meeting will take place.
The nickel crisis is part of the story
Any LME project about warehouse metal will be read against March 2022. On 8 March that year the exchange suspended nickel trading and cancelled trades after the three-month price jumped to a record $101,365 a tonne, from a close of $48,078 the day before, as Mining Weekly reported when trading resumed on 16 March. Hedge fund Elliott and trading firm Jane Street challenged the cancellation in court; the High Court found in 2023 that the LME had acted lawfully.
The episode dented trust in the exchange’s rules and in the data on where metal actually sits. The LME has since widened its stock reporting, including new transparency rules announced in 2023. A token for off-warrant metal would only be useful to lenders if they believe the metal behind it exists, is where the record says it is, and is not pledged twice. Answering that falls to warehouse operators and auditors first; the choice of ledger comes later.
How this differs from tokenized gold
Crypto investors know commodity tokens mainly through gold. Tether Gold (XAUT) and Paxos Gold (PAXG) are tokens issued by a company that holds gold bars in a vault and promises one token per ounce. In February 2026 the tokenized gold market was above $6 billion, with XAUT at about $3.5 billion and PAXG at about $2.3 billion, according to figures compiled by Tangem. We do not have a current figure.
The LME idea, as described, works differently. It is not a retail product backed by a vaulted metal and sold to anyone with a wallet. It is a financing tool for metal that already sits in exchange-approved warehouses but has no warrant, aimed at the companies that trade and finance physical metal. Whether anyone outside that circle could ever hold such a token is one of the open questions above.
It is closer to the bank and fund pilots of recent weeks, where a regulated institution puts an existing asset on a ledger for professional users. Mirae Asset, for instance, issued dollar notes on Solana that only professional investors can buy. On the other side of the market, tokenized stocks on BNB Chain traded $25.6 billion in the third quarter, most of it in a single Nasdaq-100 token.
What tokenization means here, in plain terms
Tokenization means recording ownership of an asset as a digital token on a shared ledger, so that it can be transferred or pledged without paper documents. Banks use the same idea for tokenized deposits, where the token stands for money held at the bank. For metal, the token would stand for a quantity of copper or aluminium in a named warehouse. The value of such a token rests entirely on the warehouse, the record-keeper and the legal rights behind it, none of which the LME has described yet. Our explainer on the difference between coins and tokens covers the basics.
Next step: an industry roundtable in early November
The next date to watch is the invitation-only roundtable, which the sources place in early November. Its guest list and outcome may show which lenders and warehouse operators are interested, and whether the LME moves from “exploring” to a published consultation or proposal. Until then, the only on-record fact is the exchange’s single sentence, and the rest comes from three people Reuters did not name.
