(RTTNews) - Core consumer price growth in the U.S. unexpectedly slowed in the month of February, according to a report released by the Commerce Department on Friday. Annual price growth remains elevated, but this represents a slowdown from the 4.7 percent year-over-year spike in January. The inflation readings, which are said to be preferred by the Federal Reserve, were included in the Commerce Department's report on personal income and spending in February.
