Copper futures slid more than 1 percent Wednesday, falling to the lowest level since late June as investors looked at an increasingly dour picture for global growth.
According to data released Wednesday, China's industrial production rose 9 percent in July, and its retail sales rose 12.2 percent. Both numbers missed expectations. And in more bad Chinese news, new loans for July fell nearly 70 percent from June.
In reaction to the disappointments, the industrial metal copper—which is used in everything from factory equipment to new buildings–dropped sharply overnight, hitting the lowest level since June 20.
"It's pretty much the Chinese data that really sank the copper market, and the business with new loans," said Edward Meir, a metals analyst with INTL FCStone. "All these Chinese stimulus measures really fell short when it came to changing the psychology."
