Copper broke through $7,000 a ton for the first time in three years last week, and Goldman boosted its forecast for copper to average $6,750 in the near term, up from $6,200. The firm's commodities strategists said the move was based on dollar weakness and fading worries about China's economy and policy tightening.
The analysts also said the five years of surplus into 2016 is now over and the market should face a deficit of 130 kilo tons in 2018, versus its previous forecast of a surplus of 150 kilo tons. Combining the outlook for demand and growth and currencies, the analysts said the price of copper has the potential to rise above $8,000 per ton by 2022.
