Treasuries fell yesterday as rising commodity prices sparked inflation concerns. The decline in the note was the biggest in more than a week, and came as the Reuters-CRB index of 17 commodities including oil, wheat and metals rose to the highest since January 1981. Treasury inflation-protected securities, or TIPS, are outperforming regular Treasury notes for a third straight day. TIPS pay interest at lower rates than regular Treasuries on a principal amount that's indexed to consumer prices. Regular 10-year note yields exceed 10-year TIPS yields by 2.73 percentage points, the most since June and compared with about 2.43 percentage points last month. The yield gap between the two securities represents the average expected inflation rate over the life of the securities. Some traders pointed to report out of Germany today that showed industrial production in that country rose the most in almost a decade in January as a contributor to the decline in Treasuries today
