Andy Home: Copper's high tariffs fail to lift other LME Metals

Doctor Copper isn't the same as it was before Donald Trump, President of the United States, announced an investigation in February into U.S. imported products.

Tariff trade has thrown the global supply chain into disarray, causing a feast in the U.S. but famine elsewhere.

London Metal Exchange (LME), copper is expected to close the first half with a gain 12%. Only the wild tin markets will beat it.

However, the rest of the LME is still reeling from Trump's "Liberation Day", broader tariffs.

The precious metals have been boosted by geopolitical turmoil and trade, but the industrial metals are still largely in the same place at mid-year as concerns grow about the impact of tariffs on global manufacturing.

The LME scorecard for the first half 2025.

COPPER – FEAST AND FAMILY

CME's U.S. Copper contract currently trades at a premium of $1200 per metric tonne over the LME international price.

Tariff trade has been extremely volatile in the past few months. However, the arbitrage window is still sucking up metals from around the globe.

CME stocks have exploded and LME stock are in decline as physical copper is being redirected into the U.S. LME spreads are becoming turbulent as inventory shrinks. Cash-to-three month period is in steep reverse.

Market participants expect Chinese smelters will increase exports in order to fill supply-chain holes, but the London Copper market remains a hazardous place for bears until this happens.

The U.S. government will decide whether or not to impose import tariffs. This is a sign of more turmoil ahead of the deadline in November for the Section 232 investigations into U.S. imported goods to be completed.

WILD TIN

London's tin market is a roller coaster so far this season. Early April, three-month tin reached a high of $38,395 a ton. After the metals meltdown on "Liberation Day", it fell to $28,925.

Due to the persistent pressure on supply, tin is now back above $33,500 a ton. The Bisie mine, in the Democratic Republic of Congo was quickly reopened after a short disruption. However, the Man Maw Mine in Myanmar continues to be affected by a longer-term disruption.

Wa State authorities, who control the Man Maw Mine, have been in negotiations to obtain new licenses that will allow it to be reopened after almost two years.

The flow of tin to China's smelters is still a trickle.

China's imports of tin-concentrate fell by 36.5% between January and May, and the country's metal smelters feel the pinch. According to Shanghai Metal Market, refinery production in June was down 15% year-over-year.

Since the middle of April the Shanghai Futures Exchange tin stocks have been steadily declining, while the LME inventories have halved in the first half year.

Tin is the only LME-listed metal, other than copper, that trades in a significant backwardation. This shows the supply pressures in the market.

ALUMINIUM SPLIT

Trump's import tariffs of 50% have fractured the aluminium market, but their impact is more visible in the premiums for the U.S. Midwest than the arbitrage between similar CME and LME contracts.

The LME price is now around $1,250 higher than what U.S. customers pay for their metal. The premiums are falling everywhere else, partly because of displaced metal flows as well as weak demand in Europe and Asia.

The recent London market action has largely been a massive tug-of war for the available metal, against a background of falling exchange stock.

It's difficult to distinguish the signal from noise when using aluminium.

The LME's three-month price rose from $2,335 to $2600 per ton in April, but the gain year-to date is only a modest 3.0%, falling short of analysts' expectations for the beginning of 2025.

NICKEL WEIGHED BY SURPLUS WEIGHED DOWN

LME Nickel also ends the first half 2025 with little change from its January start point.

The LME Nickel Stocks fell in May, for the first since March 2024. This is a sign of a possible slowdown in the accumulation of inventory.

How long it will last remains to be determined.

Nickel's electric dream has faded, as Chinese electric vehicles manufacturers have switched to non-nickel batteries. Indonesia continues to increase production and generate more metal.

Analysts at Macquarie Bank say that the price of LME nickel three-month is just above $15,000 per ton, which is about the same as the cost to refine nickel from Indonesian nickel-pig iron.

While the price of nickel may not be as high as it is now, any recovery will depend on Indonesia's ability to curb its growing nickel production sector.

No one is holding their breath.

ZINC WINDS DROPPING, LEAD GEARS ON.

Due to its close relationship with the automotive batteries sector, the lead market has been cushioned from the tariff turmoil of this year.

Lead is currently entering its seasonal peak demand period, which occurs when temperatures in the northern hemisphere are high and cause an increase in battery failures.

LME lead has risen 6% since the beginning of the year. It is now catching up with zinc, the LME metal that continues to be the underperformer.

According to the International Lead and Zinc Study Group, world zinc mine production increased by 5.1% in January-April.

This supply surge has led to an increase in refined production, especially in China. The Group estimates that the global refined metals market recorded a 151,000-ton surplus of supply in the period.

You don't need to look any further to see why galvanising is in such disfavor. It has fallen by 6% since 2025.
