Consumer spending rose less than forecast in March, wrapping up the weakest quarter in a year for the biggest part of the U.S. economy even as incomes accelerated.

The cost of living in the United States, excluding food and fuel, increased in January by the most in more than four years, reflecting broad-based gains that signal companies may be getting some pricing power.

Figures on retail sales and manufacturing Jan. 15 showed the world’s largest economy ended the year on a weak note, and the start of 2016 wasn’t better. The one saving grace was a pickup in consumer confidence, but that was mainly because households believed inflation will be low, making subdued wage gains look good by comparison.
