MTECHTIPS- copper market for August 2016 showed an apparent production surplus of around 154,000 metric tonnes (t) mainly due to weaker Chinese apparent refined copper demand and seasonally weak usage in other regions. When making seasonal adjustments for world refined production and usage, August showed a production surplus of about 56,000 t. The refined copper balance for the first eight months of 2016, including revisions to data previously presented, indicates a production deficit of around 91,000 t (and a seasonally adjusted deficit of about 93,000 t). This compares with a production surplus of around 10,000 t (a seasonally adjusted surplus of about 19,000 t) for the same period of 2015. In the first eight months of 2016, world apparent refined usage is estimated to have increased by around 3.8% (570,000 t) compared with that in the same period of 2015 mainly due to increases in China. Chinese apparent demand increased by around 7.5% compared with the same period of 2015 based on an 8% increase in net imports of refined copper.
