ROI-Resurgent London Metal Exchange rides speculative tsunami: Andy Home

London Metal Exchange (LME), a venerable institution of 149 years, posted record trading volume last year. This is a remarkable turnaround from the dark days four years ago when the nickel crisis was at its height.

Hong Kong Exchanges and Clearing, which owns the London market, has reappeared the benefits of the "physical market turmoil" that has marked Donald Trump's tenure in office.

The funds finally arrived.

The LME base metals market complex was flooded with speculative purchases in the fourth quarter. The average daily volume of 777.016 contracts was a quarterly record, surpassing 735.604 contracts from the second quarter 2014.

LME Futures Open Interest ended the year at a 15% increase compared to 2024, and its highest level since early-2021.

Retail investors in the U.S. flooded into CME's smaller contracts of copper.

TARIFF BOOST

Import tariffs in the United States, which are in effect in the case aluminium, and could be in place in the event of copper, has had a major impact on the physical flow of metals around the globe.

The market is betting (again?) on a Trump tariff for imported refined metals. A decision is expected in June.

LME copper trading accelerated in February when Trump launched his investigation into U.S. imports of copper. It remained there. The average daily volume rose by?12% between 2024 and 2025.

CME's flagship contract for copper, on the other hand, saw a 33% drop in activity, as investors were scared by the unprecedented volatility of arbitrage prices with London.

The U.S. exchange benefited from the disruption in the?aluminium markets following the increase in U.S. tariffs on imports to 50% in July.

CME contracts for physical aluminum premiums in the Midwest U.S.A. and Europe recorded record volumes last Year with an annual growth of 47% & 72% respectively.

Return of the Funds

Since September, institutional investors have flooded the LME.

Copper's record-breaking performance and the strong rally in all LME metals except lead have also attracted money.

LME trading experienced a dramatic change during the fourth-quarter due to the renewed enthusiasm for metals.

The copper and tin volume were at their highest levels since 2013 and 2014. Nickel posted its second best quarterly volume ever, while lead activity reached new highs. LME nickel trading was at its highest level since 2019 last year, indicating a return to confidence in the London Market after the crisis of 2022. It seems that most funds have forgiven LME for canceling nickel trades. This controversial decision was upheld in the British High Court.

SHANGHAI GETS GRAPPED BY METAL FEVER

In December, the metals mania spread to China.

Shanghai's market had been slow up to that point, with the volume of base metal futures down all over.

In the last month 2025, Chinese investors joined in on the bull market.

The Shanghai copper contract saw the most activity since November 2015, while the aluminium volumes were at their highest level in three years. Nickel turnover was also the highest it has been in four years.

The China Nonferrous Metals Industry Association, a state-backed organization, warned against blindly following a "unreasonable price rally" as tin prices reached'record levels' in December.

No one has really paid attention. Shanghai's tin market recorded a turnover of 739,900 tons on Tuesday. This is equivalent to the global consumption of two years.

Going Small in the US

Shanghai is a city that has seen a lot of speculative exuberance in the past, and this was largely due to retail investors who were trying to catch up with the latest market trend.

London has no comparable product, as very few people are wealthy enough to meet the credit requirements for direct LME trading.

There are signs that some speculators have started to participate in the CME's trading, but not for the main copper contract, but rather on smaller retail-oriented products.

Volumes of the CME micro-copper contract, which is only 2,500 lb in size, grew 20% annually to reach almost four million tons by 2025.

CME copper 'event options', which offer a simple binary bet on the price underlying, recorded turnover of 31,000 tons in December. This is more than the total volume traded for the entire year of 2024.

Both contracts were launched in 2022 and seem to serve as a bridge to allow retail investors to move from precious metals to industrial metals.

China's CNMIA is right to be concerned about excessive speculation in commodity markets that were once fringe, such as tin. However, the bull story around industrial metals has attracted more and more people to the cause.
