Wednesday’s report from the Labor Department showed that the consumer price index rose 2.9 percent in December from a year ago, the highest since July, up from 2.7 percent in November. It was the third straight increase after inflation fell to a 3 1/2 year low of 2.4 percent in September.

The drop in yields occurred as traders resumed betting on another Fed rate cut by July. Traders ignored the strong December employment data released Friday, which sparked a surge toward the highest levels in months as it sowed doubts that policymakers would cut rates at all this year.
