Andy Home: Tin price bubble is a source of trouble and toil for the global industry

London and Shanghai markets have seen a surge in tin prices, which are now at all-time highs.

According to the China Nonferrous Metals Industry Association, a state-backed organization, this rally is "unreasonable". Last month, it warned all parties to "avoid following trends blindly".

Beijing's warning hasn't stopped Chinese investors from chasing prices higher and higher.

On Thursday, the volume of trading in the tin contract at Shanghai Futures Exchange (ShFE), exceeded one million metric tons. This is more than double the annual global physical consumption.

Tin is in a clear speculative boom, and it will burst as soon as the trend changes. The mismatch between physical market size and interest in investing foreshadows future volatility.

Not just for tin. The current tidal waves of investor purchases washing through the industrial-metals sector may be a sign for other metal supply chain.

EXUBERANCE IRRATIONALE

Since several months, the London Metal Exchange (LME), tin contract has been bubbling. However, this week it exploded as Chinese investors brought with them their financial power to the rally.

On Tuesday, LME's three-month metal surpassed the previous price peak of March 2022 at $51,000 per ton and soared to $54,760 by Wednesday.

It is the lack of supply that drives this narrative.

Tin's structural issues with supply are well-known. Global mine production is concentrated in a few countries, and heavily dependent on frontier jurisdictions like the Democratic Republic of Congo or the semi-autonomous Wa State of Myanmar.

This rally is not at the right time.

The tin supply situation has improved in recent months.

Since the M23 insurgency was in danger of overrunning the Congo's mine Bisie a year earlier, the threat has diminished. Alphamin Resources, the mine operator, has raised its annual production forecast after a strong performance in the third quarter.

After a long absence, the giant Man Maw Mine in Myanmar has also begun to show signs of renewed productivity. China imported 7,190 tonnes of tin-based raw materials from Myanmar in November. This was the highest monthly total since August 2024.

According to the Indonesia Tin Exporters Association, Indonesia will continue to crackdown on illegal mining, but the official sector production quotas are expected to increase from 53,000 tones in 2025 to 60 000 tons in 2026.

There is no shortage of refined tin at the moment.

Metal producers and traders have contributed significant quantities of metal to the price rally. The combined stocks of the LME and ShFE rose from 11,000 tones at the end October to more than 19,000 tons.

Inventory was less than 5,000 tons at the previous peak of 2022.

When China's metals regulator describes the tin price's recent surge as "unreasonable", they may be right.

LIQUIDITY MISMATCH

Paraphrasing economist John Maynard Keynes: a market may remain "unreasonable", longer than you are able to remain solvent.

Investors can have a large impact on the price, especially if you're dealing with a small-scale market like tin.

Shanghai is a clear example of this.

China's commodities markets have been characterized by such speculative booms for a long time. It was alumina last year.

Chinese authorities are in a well-honed firefighting mode. They have raised trading margins and, in particular, the cost of intraday transactions, while limiting positions for non-members.

Tin's story of limited supply and increasing use as a semiconductor-solder has not only attracted the Chinese.

Over the past few years, the number of funds participating in the London Tin Market has steadily increased.

The investment fund's long position reached a record high of 2,887 contracts in late 2021 or early 2022 when tin prices were at their highest. This is equivalent to 14,435 tonnes. The investment fund long position reached a record of 5,753 contracts or 28,765 tonnes at one point last month.

The liquidity rush has increased volatility in a market that is known for its wild price swings.

Futures frenzy is causing real problems in the supply chain, as consumers and producers struggle to cover their margins.

When does price risk take precedence over liquidity risk? How long can you "remain solvent"?

FUNDS AND FUNDAMENTALS

Tin was not a popular metal a few years back. Most fund managers did not invest in tin because the market was too small both for physical volume and futures trading.

This is changing, as the world begins to realize the centrality of tin in the Internet of Things. No circuit boards, no internet. In our hyper-connected, connected world, there is very little more.

The result is that too much money floods a market unprepared to handle it.

CNMIA is the voice of the world's biggest refined tin producers and users. It is very clear on the dangers posed to the present exuberance.

The rapid price rise driven by funds has diverged from industry fundamentals and magnified market risks, harming the global chain of industry.

Tin's dramatic story may be a timely reminder for other metals in demand, such as copper, as fund money floods the industrial metals sector in search of other hard assets than gold and silver.
