History Of The London Metal Exchange

The origins of the London Metal Exchange can be traced as far back as 1571 with the opening of the Royal Exchange in London. Before the creation of the exchange, business between traders was carried out in London coffee houses, where the trading ring tradition began.

The London Metal Exchange was founded in 1877. At first, the only metal traded on the exchange was copper (rate and scrap copper both had prices), although zinc and lead prices were soon added in 1920.

Upon the outbreak of World War 2, the London Metal Exchange was closed. It would not re-open until 1953. Following this, many new metals were added to the inventory of the exchange. In 2011, the exchange stopped trading plastics. The London Metal Exchange was under the ownership of its members until 2021 when Hong Kong Exchanges and Clearing Limited purchased the LME for £1.4 billion.

Contract Types

A key part of understanding the London Metal Exchange is to know the types of contracts available. Contract lengths can vary from one week to multiple months or even multiple yearlong contracts. The main types of contracts will be explained briefly here.


A futures contract on the London Metal Exchange works as any other future would. These are an obligation to buy or sell the specified asset (metal) on a set date and at an agreed fixed price. Any futures that are not closed out by an opposite purchase are physically settled.


An option is similar to a future. In this case, the option provides the right, but not the obligation, to buy or sell the specified asset (metal) on a set date and at an agreed fixed price. Using options contracts on the London Metal Exchange warrants further hedging on trades and investments due to the increased flexibility.


TAPOs are Traded Average Price Options. They are another flexible way for the London Metal Exchange to hedge against fluctuating metal prices. TAPOs are financially settled Asian options. The payoff is dependent on the Monthly Average Settlement Price (MASP) for the contract month.

Monthly Average Futures

This instrument is designed for London Metal Exchange members who need to hedge against the monthly average price. It is the first of its type in the world. Participants enter into a fixed price and settle the difference against the floating price (the Monthly Average Settlement Price or MASP) at the end of the averaging period. A keen trader always notices the fluctuations during the month and uses this tool to hedge against them.

Trade At Settlement

At the London Metal Exchange, trade-at-settlement (TAS) contracts are only available on LME 3-month Nickel. Participants use TAS contracts to enter an order to buy or sell a contract at a price that is either equal to, or several ticks above or below, the yet to be established 3-month closing price.

Participants should have studied the nickel price history before entering this contract. Once the closing price is set, the TAS order delivers the 3-month contract.

HKEX London Minis

HKEX London Minis are designed specifically for Asian participants. They are traded and priced in CNH or US dollars and are available in six metals: aluminium, zinc, copper, nickel, tin and lead.


These are five-tonne cash-settled monthly futures contracts. They are settled against the London Metal Exchanges ‘parent’ contract, LME Official Settlement Price. Investors can be confident that the price at settlement is reflective of global supply and demand.

LME Index

The London Metal Exchange Index consists of six metals with the following weights: aluminium (42.8%), copper (31.2%), zinc (14.8%), lead (8.2%), nickel (2%) and tin (1%). The weightings are derived from trade liquidity and global production volume over five years. The forecast for the index can be found at

Trading Methods

The London Metal Exchange has three different methods of trading: open outcry, electronic trading and telephone trading. Open outcry is the traditional form of trading where traders meet face-to-face on the trading floor in pits or rings at set times of the day. The LME is the only remaining physical commodity exchange in Europe and it is currently bucking a global trend of switching completely to electronic trading.

After closing for covid and then being slated to close permanently, the London Metal Exchange announced the news that they were “to reopen trading floor” after uproar from the public and high-profile individuals like Nigel Farage.

Electronic trading has been used at the London Metal Exchange since 2001. The exchange uses its platform, LME Select, to facilitate this form of trading, allowing people to trade from home or foreign offices. This platform now handles the majority of LME business.

Ring Trading

Ring trading is a tradition at the London Metal Exchange that has stood for years. Ring trading is very important to the process of price discovery, which is how official prices are set. There are two ring trade sessions in the morning and afternoon. Each of the nine metal contracts is traded in two blocks with a five-minute session for each.

Traders with Ring Dealing membership are entitled to trade in the ring. In total, nine companies have the exclusive right to trade in the ring. In addition to these nine, there are around 100 companies involved in the London Metal Exchange.
