Summary Box: Spain's troubles pressure commodities

BROAD DECLINE: Prices for metals, energy and most agricultural crop fell as concerns about Europe's economic health bubbled back to the surface after Spain said that the amount of bad loans at its banks rose to an 18-year high.

ECONOMIC WORRIES: Spain's problems have added to ongoing concerns about global economic growth because China's growth also has slowed. That could affect the future demand for raw materials, including oil, industrial metals, corn and soybeans.

COTTON POPS: Cotton prices rose nearly 3 percent after a report showed that China's crop estimates were smaller than expected.
