Copper was flat at $7,042.50 per tonne on Wednesday, according to Reuters.

BHP Billiton (LSE:BLT) reported that its copper production increased to 1.7 million tonnes in fiscal year 2014 and anticipated a further increase this year. This is consistent with industry-wide expectations of increased copper supply in the year ahead. Other factors impacting copper prices include an eight-month high of U.S. home resales in June, which indicates a growing housing market, and the Indonesian elections, which may alter existing mineral export laws in the country.
