MELBOURNE, March 10 (Reuters) - London copper edged up on Friday after six straight sessions of decline, but was set for its steepest weekly loss since August after an influx of deliveries into exchange warehouses this week doused near-term supply concerns.
LME copper stocks surged by 38,775 tonnes to 327,300 tonnes, the latest data showed, bringing total inventories to the highest since December and raising concerns about demand in Asia.
Stocks have jumped by more than half since the start of March as traders have opted to deliver rather than pay soaring fees to roll contracts CMCUT-0.
“The slide in commodities, triggered by rising stockpiles earlier this week, continued as investors cut bullish bets built up over the course of the year,” ANZ said in a report.

It still has work to do cleaning up its skies, with poor enforcement of environmental laws and inadequate monitoring, the environment minister said on Thursday. A more severe crackdown could impede its production of metals.
A steep drop in China’s aggregate financing, seen as a proxy for credit available to store metals, spooked traders who worry that Beijing may be clamping down on the type of credit used by the metals industry.
