Copper futures add one percent

Copper futures rose nearly one percent in American trade even as the dollar advanced, amid a lack of data from the US, the world's largest economy. 

As of 02:34 GMT, copper futures due on July 15 rose 0.79% to $259.95 a pound from the opening of $258.40, while the dollar index rose 0.19% to 97.35 from the opening of 97.16. 

Earlier from the US, Federal Reserve Bank of New York President William Dudley spoke at the North Country Chamber of Commerce, in Plattsburgh, pointing to the brisk gains in wages and inflation, and saying the current economic conditions are better, as inflation and unemployment levels near the targets. 

Dudley cautioned there's still a long road for full recovery, adding that confidence levels are high now and the US economy is almost at full employment, as wage increases go along with productivity levels, while the improvement in hiring rates will ensure gradually increasing wages, and warning that slow interest rates hikes could push the economy into recession.
