Does the battle over LME aluminum stocks signal or cause noise? Andy Home

Where has all the aluminum gone? In the warehouses of London Metal Exchange (LME), there were 1.3 million tons of aluminium two years ago. Since then, the inventory has almost halved to levels last seen in 2020.

London's market is becoming more turbulent as traders compete for what's left. This may not be apparent at first glance, but the calm exterior masks a lot of turmoil.

Short-dated spreads are tightening and becoming volatile. While the LME outright three-month price has been tethered around $2,500 per ton, the LME outright three-month prices have been sedately hovering around that level.

LME's aluminium market has seen titanic battles for metal between traders with deep pockets. The game has taken on an entirely new dimension ever since the exchange in April of last year banned the delivery of new Russian aluminum.

This latest LME stock battle echoes past LME stock battles, but this time the LME noise could be masking an essential market signal.

A LARGE MARK, LARGE POSTIONS

The biggest base metals market in the world is aluminium, with an annual consumption of about 100 million tons. Aluminium traders are known to have taken outlandishly big positions on the London market.

This mega-long position has been causing havoc in nearby spread structures for the past month.

The benchmark period is three months of cash The market has moved from a comfortable contagious of more than $42 per tonne in April, to a small backwardation.

Last week, the "tom-next spread", which is a cost-effective way to roll a position over night and an indicator of market stress was traded at a backwardation of $12.30 per ton.

There is no doubt that someone is looking to buy a large amount of aluminium, but the LME has only 321,800 tonnes of metal available in its warehouses. Two-thirds are Russian.

In April of last year, Russian metal was banned from the United States and United Kingdom. It is now subject to quotas and a complete ban in Europe will be implemented at the end 2026. This makes it less desirable.

There's no way to tell how many of the 323,000 tonnes of metal in LME storage that are also Russian, but there is no indication of this metal being moved to warrant to ease the spread tightness.

If the goal of the squeeze is to get metal out of deep non-LME shadow storage, then it does not seem to work. So far, this month's arrivals have been a mere 150 tons.

The LME ban on Russian metal after April 13, 2020 may hinder the normal functioning of the LME stock grab trade. This is to tighten the spreads in order to force holders of metal to release it.

This assumes that there are a large number of aluminum products, Russian or otherwise, available for LME deliveries.

CHINA'S IMPORT AFFECTION GROWS

This assumption is beginning to seem a bit questionable given the absence of significant arrivals in the LME system of any type of aluminium since March.

China's imports of Russian metal so far in this year indicate that even Russian metal is in high demand.

Since the beginning of the Ukraine war in 2022, the country has been buying up Russian aluminum that was shunned in the West.

Imports of Russian aluminum primary by China grew from 291,000 tonnes in 2021, to 1,13 million tonnes in 2024. In 2025, the pace of growth has increased again. Imports increased by 48% on an annual basis to 741,000 tonnes in January-April.

The structural changes in aluminium supply are the main reason for China's appetite to import metal.

The country's smelters have reached the annual cap set by the government of 45 million tonnes. Since the beginning of the year, the national annualised run rate has remained at around 44 million tons.

The domestic market for primary metals is tightening up against a backdrop that includes a robust demand from solar energy.

The Shanghai Futures Exchange has seen stocks fall to their lowest level in 16 months, 110,000 tons. Also, the curve for forward trading is now backwardated.

SCRAP WARS

China's stated strategy is to increase secondary production of recyclable metals to compensate for the cap in primary metal production.

This may become more difficult as recyclable materials flow to the United States, because they are exempted from the tariffs of 50% imposed by Donald Trump's administration.

The second major structural shift could lead to a tightening of the global scrap supply, which would force processors outside the United States to use more primary material.

The scrap flows to China, which is the largest buyer in the world, could be further disrupted by the European Union imposing export tariffs. This would stop what they call "scrap leakedage". The United States is now the threat. Originally, it was China.

Testing Availability

This latest mega-trade to grab a piece of the available stock is just the latest in an extensive history of mega-trades.

It doesn't seem to be drawing any metal into the system.

This story may have a Russian twist, but it is also a test to see if the market can be supplied. So far, supply has not been satisfactory.

The LME stock churn will appear more like a signal of a downtrend in the LME's inventory the longer it continues.
