Consumer prices as measured by the personal consumption expenditures (PCE) price index, excluding the volatile food and energy components, increased 0.7% last month after gaining 0.4% in March, the Commerce Department said on Friday. In the 12 months through April, the so-called core PCE price index vaulted 3.1%. That followed a 1.9% year-on-year gain in March.
The dollar's performance has been tied to US Treasury yields for most of 2021, after concern about rising inflation in the United States and a stimulus-fuelled economic rebound triggered a jump in Treasury yields.
The dollar index was last down 0.11% against a basket of currencies at 92.108. It is holding above a three-week low of 91.995 reached on Thursday.
Futures: Dow up 0.2%, S&P down 0.1%, Nasdaq slips 0.5%.
US consumer prices are expected to tick higher to 0.4% in February from 0.3% in the prior month. However, underlying prices are likely to remain unchanged.
