The 2.40% level held

A week ago, Bill Gross was warning that 10-year yields could break 2.40%, The short-term importance of that level is obvious -- it was the July high. But Gross also warned it represented resistance at a major downtrend since the 1980s.

The drop today broke the October low. It comes after a roundly weak CPI report.
