Copper falls on firm dollar and China's measures to curb prices

Copper prices fell on Thursday, as the US dollar rose against most majors, amid concerns about the Chinese government's measures to curb prices.

Beijing decided to release copper, aluminum and zinc from its national reserves to reduce prices and to reach medium-term stability in prices.

Citigroup analysts said the last strategic stocks release in China was in November 2010, and did not include copper.

The dollar index rose against a basket of major currencies by 0.7% to 91.8 points as of 13:08 GMT, after hitting a high of 91.8 points and a low of 91.3 points.

Copper July futures fell 2.6% to $4.27 per pound as of 13:08 GMT, after hitting a high of $4.34 and a low of $4.27.
