Bonos del tesoro a 10 años en niveles más bajos en años.

Yields on U.S. 10- and 30-year Treasuries hit new historic lows this morning, as bonds across the world surged. In Europe, Spanish yields also hit a record low while Italian bonds rose. The European Central Bank is said to be looking at changing the rules of its asset-purchase program to increase the securities it's eligible to buy as rising bonds push more yields below the bank's deposit rate.
