The central bank's preferred inflation measure, the personal consumption expenditures price index, was up 1.2% in November from a year ago, while core PCE increased less than 0.1%.
"The Fed is determined to tighten, though several participants urged for more data-dependent criteria so that investors would get away from a conviction the hike will be in the middle of the year. The Fed may hike rates even if headline inflation runs well below target for a time," said Chris Low of FTN Financial.
According to the minutes, "most participants" agreed to adding language in the FOMC statement about being patient in deciding to raise interest rates, saying it indicated the process was unlikely to begin "for at least the next couple of meetings."
That suggested the first rate hike could come earlier than expected, perhaps as soon as April, after the January and March meetings, said Omer Esiner of Commonwealth Foreign Exchange.
