For those paying attention, the metals market is sending some very worrying signs. Copper and other metals have been going through a rough patch, but yesterday seemed to really spell doom. Copper plunged into a bear market, zinc plummeted, and even gold took a big hit despite the panic across markets. Industrial commodities are a good bellwether for economic activity, and while the markets are partly plunging on worries over the Chinese economy, the big drops signal that the whole world could be in for a recession.

FINSUM: We are growing increasingly concerned about the message that metals markets are sending. The big drop across the board in industrial commodities is quite worrying. Hopefully it is a short-term overreaction to the trouble in emerging markets.
