The super-squeeze in the tin market rolls on.
LME time-spreads remain acutely stressed. Cash tin closed on Monday valued at $28,250, commanding a $1,200-per tonne premium over three-month metal. The backwardation has been wider, flexing out to $6,500 in February, but is still extreme by any historical yardstick.
Step away from the LME paper market into the physical arena and things get even uglier with Fastmarkets lifting its premium assessments to record levels of up to $2,000 per tonne over LME cash.
Parts of the world seem to have run out of the metal essential for circuit-board soldering.
China is now stepping up as the supplier of last resort, the country flipping from net importer to net exporter of refined tin.
China is the world’s largest tin producer but was a steady net importer over most of 2019 and all of 2020.
That changed in February and March’s exports of 939 tonnes were the highest monthly tally since April 2019.
Cumulative exports over the first quarter were 2,151 tonnes, already almost half last year’s count.
Imports, meanwhile, have almost dried up and China flipped to marginal net exporter over the first quarter of 2021.
This may, as the International Tin Association notes, reflect some demand suppression in China due to the current high price environment.
But the most powerful driver is the premium commanded for spot tin in the rest of the world which has forced open an export-friendly arbitrage between the Shanghai Futures Exchange’s (ShFE) tin contract and the LME.
As long as that arbitrage window remains open, more exports can be expected to flow through it.
The rest of the world needs this supply.
Indonesian exports fall
Super-high prices have so far failed to generate a producer supply response outside of China.
Shipments from Indonesia, the world’s largest exporter of tin, slid 24% over the first three months of 2021, extending a downtrend that has been running since 2018.
The country’s top producer PT Timah has guided to lower production and sales this year. It remains to be seen whether the private tin sector can lift production and, equally importantly, get it exported through Indonesia’s tight controls.
Meanwhile, a furnace outage at Malaysia’s MSC and the deferral of around 500 tonnes of production wouldn’t normally make the headlines but right now it’s another unwanted hit to an already struggling supply chain.
Physical market seizes up
Parts of the physical supply chain appear to have almost totally seized up.
Fastmarkets has been lifting its assessments of physical premiums since the start of this year and all regions are now at record highs.
Need tin urgently in Europe? It’ll cost you at least $1,000 per tonne over the LME cash price and that’s assuming you can find anyone to sell to you.
If you need it in the United States, it’s going to cost you at least $2,000 over LME cash and possibly quite a lot more, again assuming you can find a seller.
Taiwanese premiums have also shot up recently to $800-900 per tonne, even though Kaohsiung is one of the few LME warehouse locations still to hold metal, albeit only 145 tonnes.
Indeed, the stress on physical supplies is preventing LME stocks from rebuilding despite that massive backwardation.
The high premium for LME delivery has enticed odd parcels of metal into exchange warehouses but what has arrived has turned around and departed just as quickly.
LME inventory currently stands at just 1,290 tonnes, 570 tonnes lower than at the start of the year. Moreover, a third of that is earmarked for physical load-out, attesting to the continued strong demand for units across the physical supply chain.
Low LME stocks are in turn keeping time-spreads tight and the cash price elevated, which will help keep Chinese exports flowing through the arbitrage gap.
China to the rescue?
Visible inventory in China is higher. ShFE stocks currently total 7,512 tonnes, although they have fallen from a March high of 8,853 tonnes in line with the seasonal pattern around the country’s new year holidays.
Chinese refined tin production is rising and supplies of raw material from Myanmar appear to be unaffected by the political upheaval in that country, so far at least.
China now holds the key to the immediate price landscape. Indonesian exports may ramp up later this year but until they do Chinese exports are going to be the most significant route to alleviating the super-squeeze in the rest of the world.
Just how much metal the country can itself afford to lose in a global market defined by scarcity remains to be seen.
