How London Metal Exchange Works?

London Metal Exchange (LME) is an international commodities trading platform that enables traders, hedgers, and speculators to exchange futures and options contracts where the underlying assets are different metals, including non-ferrous, ferrous, E.V., and precious metals. There are three different mechanisms of trading on LME:

  1. Open Outcry: This age-old system allows the traders to engage in face-to-face ring trading pit. However, with the flaring popularity of e-trading, the existence of this system is skeptical.
  2. Telephone System: It is a facility that trades LME components 24×7 through the telephone market.
  3. LME Select: It is an electronic trading platform that functions just like any other stock market.

Notably, LME has 7 different ways of trading metal and related contracts, including options, futures, Monthly Average Futures, TAPOs, Trade at Settlement, LMEminis, and HKEX London Minis. Amidst the rising preference for electronic trading, this is Europe’s kind commodities market with an open outcry model for the physical Exchange of metals. It is a widely used platform by industrial hedgers to mitigate the price fluctuation risk of buying and selling metals in the future. Also, it is one of the favorite profit-making avenues for speculators who target short-term price changes of metals.

History

However, the initial traces of a platform for metal commodities trading are deeply rooted in the establishment of the Royal Exchange, London, in 1571; the London Metal Exchange (LME) was officially chartered in 1877. The primary purpose of LME was to address the risks associated with metals price fluctuations that occurred amidst the Industrial Revolution of 1760-1840. Initially, in the 1800s, the merchants traded metals like copper and tin informally in coffee houses (especially the Jerusalem Coffee House), but the formation of LME formalized such trades with forward contracts and an open outcry trading system, which is still now a popular exchange platform for metal traders.

Although LME was temporarily closed during 1914 due to the onset of World War I, it was shortly opened during the autumn season of the year. The Exchange has expanded its contracts and delivery periods to suit industrial needs and maintains strict quality standards for metals. The LME is a global trade-driven market with approved warehouses worldwide, used mainly by metal producers, processors, and consumers for hedging purposes.

Later, in 1985, a crisis occurred in the London Metal Exchange market with the collapse of the World Tin Council’s buffer stocks. Also, in 1996, the London Metal Exchange copper market witnessed another crisis caused by a Sumitomo Corp trader. Further, in 2005, the market was disrupted by the running away of a Chinese government trader, Liu Qibing.

After all these ups and downs, LME made significant changes in its administration and strategic direction. Then, between 2011 and 2012, the Exchange formed its own clearing house and finally got acquired by the Hong Kong Exchange for £1.4 billion.

Examples

LME has been facilitating hedging and speculation trades since the late 1800s for those who want to invest or make profits from non-ferrous metals. Let us have an overview of this unusual commodities market through the following examples:

Example #1 

Suppose Mr. Holmes has a keen interest in aluminum. He expects the price of this metal to decline in the next three months. According to him, aluminum will drop by 3.7% during this period from its current price of $2289. Therefore, he enters into a three-month London Metal Exchange aluminum futures contract of a lot size of 25 tons, freezing a future selling price of $2289, with an expectation of making a considerable profit from the fall in the prices of the underlying commodity.

Example #2

On May 07, 2024, Barchart article of TradingView –https://www.barchart.com/story/news/26024015/is-copper-heading-for-a-new-record-high, it was discussed that the price of July COMEX copper futures was $4.6255 per pound on May 6, 2024, approaching towards its previous high of $5.01 in March 2022. On May 14, 2024, these futures contracts reached a new high above $5. Indeed, on May 20, 2024, it touched a peak of $5.1990 per pound before its price correction with a fall below $4.50. Notably, the three-month London Metals Exchange copper forwards climbed up to $11,104.50 per ton on May 20, 2024, breaking through its March 2022 previous high of $10,845.

Since 2005, copper has been rallying in an uptrend, with COMEX futures prices above $2 since early 2016 and above $3 since October 2020. Moreover, copper futures have consistently seen higher low and high values over the past years, while the metal is considered a key economic indicator, particularly for China.

The CPER ETF, which tracks COMEX copper futures, reached a record high in May 2024, with shares priced at $27.79 and AUM above $236 million. It trades approximately 320,000 shares every day at a management fee of 0.88%. The DBB ETF comprises other metals alongside copper, such as aluminum, lead, nickel, tin, and zinc. The DBB ETF traded at $20.11 per share, with an AUM of $190 million. While this ETF experiences a daily trading of more than 223,500 shares daily, its management fee is 0.77%. However, both CPER and DBB are available for Exchange only during U.S. market hours; both of these ETFs effectively track the base metals prices over time.
