Consumer prices in the US rose 1.4% in January compared to a year ago, showing signs of accelerating inflation. While rising costs for housing and healthcare were offset by lower oil prices, core inflation excluding food and energy rose 0.3% for the month and 2.2% over the last year. The Federal Reserve is monitoring inflation closely as it aims for a target of 2% annual inflation. While lower gas prices and a strong dollar have kept inflation down, housing costs continue to rise steadily. The report suggests inflation may be picking up gradually in line with the Fed's goals.
