LONDON, Jan 14 (Reuters) – A sudden plunge in the price of copper pulled the shares of global miner Glencore to their lowest level on record on Wednesday and risks frustrating any intention to make a fresh move on larger rival Rio Tinto.
Copper prices slid to their lowest in 5-1/2 years after a downward revision to global growth forecasts by the World Bank and shares in Glencore lost as much as 12 percent to 236.20 pence on Wednesday. Glencore, among the large diversified miners, has the largest exposure to copper.
If sustained, the steeper fall in copper prices compared with that of iron ore so far this year, might derail any potential move by Glencore to take over Australian miner Rio Tinto , which is heavily exposed to iron ore.
After Glencore’s first takeover approach was rebuffed by Rio last summer, the market was widely expecting Swiss-based Glencore to make another attempt this year. The steeper fall last year in prices of iron compared with base metals made Rio a more affordable target for Glencore.
That has been partially reversed this year. Copper has lost almost 12 percent of its value, while iron ore has lost less than 5 percent.
