Weaker currencies help many firms cut costs, fueling new projects and adding to a global glut
RIO DE JANEIRO—Even as iron ore prices have collapsed, Brazilian giant Vale SA is building a $16 billion iron-ore operation that it touts as “the biggest project in our history and in international mining.” How? Because its costs are collapsing as well.
From South America to Australia, plunging currencies in mineral-rich nations are helping some companies expand their mines—and contributing to a glut of production that has saturated markets and driven prices down.
The cost of producing many commodities is “dropping like a stone,” said Goldman Sachs’s head of commodities research, Jeff Currie, who describes it as a “negative feedback” loop. The dynamic helps explain why commodity busts can be so long-lived.
The hope for recovery in commodities markets rests with the prospect that producers will run out of money or tire of losses and shut their facilities, bringing supply back into balance with weakened demand.
