After languishing for the past two years in a tight range despite recurring speculation about declining global supply, copper has finally broken out, surging to the highest price in the past year, just shy of $9,000 a ton as supply cuts hit the market; At the same time the price of the world's "other" most important mined commodity has diverged, as iron ore has tumbled amid growing demand headwinds out of China's comatose housing sector where not even ghost cities are being built any more.

Copper surged almost 5% this week, ending a months-long spell of inertia, as investors focused on risks to supply at various global mines and smelters. As Bloomberg adds, traders also warmed to the idea that the worst of a global downturn is in the past, particularly for metals like copper that are increasingly used in electric vehicles and renewables.

Yet the commodity crash of recent years is hardly over, as signs of the headwinds in traditional industrial sectors are still all too obvious in the iron ore market, where futures fell below $100 a ton for the first time in seven months on Friday as investors bet that China’s years-long property crisis will run through 2024, keeping a lid on demand.

Indeed, while the mood surrounding copper has turned almost euphoric, sentiment on iron ore has soured since the conclusion of the latest National People’s Congress in Beijing, where the CCP set a 5% goal for economic growth, but offered few new measures that would boost infrastructure or other construction-intensive sectors.

As a result, the main steelmaking ingredient has shed more than 30% since early January as hopes of a meaningful revival in construction activity faded. Loss-making steel mills are buying less ore, and stockpiles are piling up at Chinese ports. The latest drop will embolden those who believe that the effects of President Xi Jinping’s property crackdown still have significant room to run, and that last year’s rally in iron ore may have been a false dawn.

Meanwhile, as Bloomberg notes, on Friday there were fresh signs that weakness in China’s industrial economy is hitting the copper market too, with stockpiles tracked by the Shanghai Futures Exchange surging to the highest level since the early days of the pandemic. The hope is that headwinds in traditional industrial areas will be offset by an ongoing surge in usage in electric vehicles and renewables.

And while industrial conditions in Europe and the US also look soft, there’s growing optimism about copper usage in India, where rising investment has helped fuel blowout growth rates of more than 8% — making it the fastest-growing major economy.

In any case, with the demand side of the equation still questionable, the main catalyst behind copper’s powerful rally is an unexpected tightening in global mine supplies, driven mainly by last year’s closure of a giant mine in Panama (discussed here), but there are also growing worries about output in Zambia, which is facing an El Niño-induced power crisis.

On Wednesday, copper prices jumped on huge volumes after smelters in China held a crisis meeting on how to cope with a sharp drop in processing fees following disruptions to supplies of mined ore. The group stopped short of coordinated production cuts, but pledged to re-arrange maintenance work, reduce runs and delay the startup of new projects. In the coming weeks investors will be watching Shanghai exchange inventories closely to gauge both the strength of demand and the extent of any capacity curtailments.

“The increase in SHFE stockpiles has been bigger than we’d anticipated, but we expect to see them coming down over the next few weeks,” Colin Hamilton, managing director for commodities research at BMO Capital Markets, said by phone. “If the pace of the inventory builds doesn’t start to slow, investors will start to question whether smelters are actually cutting and whether the impact of weak construction activity is starting to weigh more heavily on the market.”

Few have been as happy with the recent surge in copper prices as Goldman's commodity team, where copper has long been a preferred trade (even if it may have cost the former team head Jeff Currie his job due to his unbridled enthusiasm for copper in the past two years which saw many hedge fund clients suffer major losses).

As Goldman's Nicholas Snowdon writes in a note titled "Copper's time is now" (available to pro subscribers in the usual place)...

... there has been a "turn in the industrial cycle." Specifically according to the Goldman analyst, after a prolonged downturn, "incremental evidence now points to a bottoming out in the industrial cycle, with the global manufacturing PMI in expansion for the first time since September 2022." As a result, Goldman now expects copper to rise to $10,000/t by year-end and then $12,000/t by end of Q1-25.’

Here are the details:

Previous inflexions in global manufacturing cycles have been associated with subsequent sustained industrial metals upside, with copper and aluminium rising on average 25% and 9% over the next 12 months. Whilst seasonal surpluses have so far limited a tightening alignment at a micro level, we expect deficit inflexions to play out from quarter end, particularly for metals with severe supply binds. Supplemented by the influence of anticipated Fed easing ahead in a non-recessionary growth setting, another historically positive performance factor for metals, this should support further upside ahead with copper the headline act in this regard.

Goldman then turns to what it calls China's "green policy put":

Much of the recent focus on the “Two Sessions” event centred on the lack of significant broad stimulus, and in particular the limited property support. In our view it would be wrong – just as in 2022 and 2023 – to assume that this will result in weak onshore metals demand. Beijing’s emphasis on rapid growth in the metals intensive green economy, as an offset to property declines, continues to act as a policy put for green metals demand. After last year’s strong trends, evidence year-to-date is again supportive with aluminium and copper apparent demand rising 17% and 12% y/y respectively. Moreover, the potential for a ‘cash for clunkers’ initiative could provide meaningful right tail risk to that healthy demand base case. Yet there are also clear metal losers in this divergent policy setting, with ongoing pressure on property related steel demand generating recent sharp iron ore downside.

Meanwhile, Snowdon believes that the driver behind Goldman's long-running bullish view on copper - a global supply shock - continues:

Copper’s supply shock progresses. The metal with most significant upside potential is copper, in our view. The supply shock which began with aggressive concentrate destocking and then sharp mine supply downgrades last year, has now advanced to an increasing bind on metal production, as reflected in this week's China smelter supply rationing signal. With continued positive momentum in China's copper demand, a healthy refined import trend should generate a substantial ex-China refined deficit this year. With LME stocks having halved from Q4 peak, China’s imminent seasonal demand inflection should accelerate a path into extreme tightness by H2. Structural supply underinvestment, best reflected in peak mine supply we expect next year, implies that demand destruction will need to be the persistent solver on scarcity, an effect requiring substantially higher pricing than current, in our view. In this context, we maintain our view that the copper price will surge into next year (GSe 2025 $15,000/t average), expecting copper to rise to $10,000/t by year-end and then $12,000/t by end of Q1-25’

Another reason why Goldman is doubling down on its bullish copper outlook: gold.

The sharp rally in gold price since the beginning of March has ended the period of consolidation that had been present since late December. Whilst the initial catalyst for the break higher came from a (gold) supportive turn in US data and real rates, the move has been significantly amplified by short term systematic buying, which suggests less sticky upside. In this context, we expect gold to consolidate for now, with our economists near term view on rates and the dollar suggesting limited near-term catalysts for further upside momentum. Yet, a substantive retracement lower will also likely be limited by resilience in physical buying channels. Nonetheless, in the midterm we continue to hold a constructive view on gold underpinned by persistent strength in EM demand as well as eventual Fed easing, which should crucially reactivate the largely for now dormant ETF buying channel. In this context, we increase our average gold price forecast for 2024 from $2,090/toz to $2,180/toz, targeting a move to $2,300/toz by year-end.
