The copper market has started out the week under pressure, with many traders appearing to be disappointed with the lack of a Chinese bank reserve requirement reduction after the Lunar New Year holiday. While a Zambian copper mine continues to see labor conflict over wages, workers there have returned to work pending further negotiations. While concern over lost supply from that situation wasn't a major market moving event last week, it is possible that news provided copper prices with some minor pressure this morning. Some copper traders are disappointed by the lack of movement on Greek debt talks, while other traders feel that US economic data today could be very important for providing direction for copper prices during the near future.
