Base metals on the London Metal Exchange were mostly lower during morning trading, with tin recording the only positive move despite continued strength in lead and nickel prices.

Falling 1.8% over the morning, copper’s three-month price has lost most of Tuesday’s gains, with the red metal drifting back towards its $6,800 per tonne support level.

Despite ongoing volatility in global stocks, partly due to China’s ban on imported scrap copper, the metal’s supply-demand dynamics continue to disappoint.

Coupled with easing trade relations between the United States and China – exemplified in China’s cut on import duty for passenger cars to 15%, further opening the Chinese economy – copper prices continue to display broad steadiness.

Here is how the LME base metals complex looked at 13.14 pm London time:
