Yangshan Copper Premiums Rise as Import Ratio Recovers

Yangshan copper warrant premiums averaged US$136 per metric tonne on October 14, according to Shanghai Metals Market's assessment, published at 05:23 UTC. SMM reported a recovering Shanghai Futures Exchange/London Metal Exchange price ratio, narrower nearby London backwardation and tight supply of registered warrants. For those of us holding copper miners, China's import market showed a more favourable exchange-price relationship alongside continued pressure on the availability of registered refined copper.

Does that make imported copper profitable again? The LME's explanation of London-Shanghai arbitrage, checked October 14, says the calculation depends on exchange rates, tax, freight and physical premiums as well as futures prices. A higher Shanghai price relative to London improves the comparison for an importer buying overseas and selling in China, all else equal. Backwardation means nearby delivery costs more than later delivery, as the LME glossary explains; a narrower gap reduces that extra cost relative to later-dated pricing. SMM gave no numerical ratio or spread reading from which we could calculate an import profit.

The reported availability constraint concerns registered warrants. SMM's October 14 assessment, published at 05:23 UTC, put bill-of-lading premiums at US$129 per metric tonne, with quotations referencing arrivals from October to early November. It attributed elevated warrant offers to tight registered-warrant supply. But SMM also adjusted warrant quotations for a pricing-period change, so we cannot read the assessment's increase as a direct measure of stronger consumption. Its account establishes neither the quantity of copper available nor a global refined-copper shortage.

For you as a miner shareholder, the potential benefit runs through sustained copper prices and the prices your company actually receives. The LME's copper contract page, checked October 14, describes its Official Price as a benchmark used in copper contracts. In Copper Prices Rise Amid Rate Optimism, we followed the exchange rally through to producers' realized prices. Today's report adds physical-market evidence: the exchange component of import pricing improved while registered-warrant offers stayed elevated. It does not establish that any particular miner receives the Yangshan premium, nor does it disclose import tonnage.

If you own Freeport-McMoRan (NYSE: FCX) or Teck (NYSE: TECK), we would watch whether this local supply pressure persists long enough to support the prices they receive. Higher physical premiums also raise import costs, so they can absorb part of the exchange-price improvement. More cargoes becoming available could ease those premiums even if futures prices stay firm. We need subsequent assessments to show whether tight registered supply persists through the arrival window SMM identified.

We will follow registered-warrant availability into early November, with results next due from Freeport on October 27 and Teck on October 29.
