LME copper stock swells in US and Asia as cargoes are diverted to its warehouses

Available copper inventories The London Metal Exchange has seen its trading volume increase by 11 months, as traders from the U.S.A. and Asia have increasingly turned to the exchange for metal storage.

After more than 20,000 tonnes of copper were delivered to New Orleans and Baltimore over the last three weeks as well as similar inflows into South Korea and Taiwan, the amount of copper available in LME warehouses reached 160,625 tons on Wednesday. This is the highest since late February of last year.

Copper was shipped in large volumes to the United States before possible import tariffs. Higher?prices at the U.S. Comex Exchange encouraged the LME to ship metal.

Recent price spreads or arbitrage between the two have flipped.

Alastair Munro is a senior base metals analyst at broker Marex. He said that Comex 'copper now trades at a discounted price to LME. This means the latter will naturally attract the 'inflows, as it is the premium location.

LSEG data show that the front-month Comex contract for copper is currently trading at a price of about $60 a ton lower than the LME. The arbitrage for shipping metal from the Shanghai Futures Exchange back to the LME is also open.

Two industry sources have reported inquiries from traders who are delivering cargoes by sea and want to put the metal in U.S. LME storage facilities, as delivery into Comex, their original destination, is no longer profitable.

One source, who declined to be identified because he wasn't authorised to talk to the media, said: "They are scrambling for room."

LME copper inventories in New ?Orleans From zero on January 15, the number of tons has risen to 16,975 on February 4 - the highest level since April 2024. And 4,625 tonnes?has flown into Baltimore The highest total since August 20,22.

This means that there are 21,600 tonnes of copper in U.S. LME storage warehouses, which is 13.4% of the available LME copper.

Around 15,000 tons of copper have been shipped to LME warehouses from Asia. Gwangyang, South Korea Busan This week.

Munro believes this is copper of African origin, as the downstream purchasing in China's top metals consumer pauses before the Lunar New Year holiday at the end of this month. (Reporting and editing by Pratima Deai, Alexander Smith, and Tom Daly)
