(Bloomberg) — U.S. consumer prices climbed in March by the most since 2012, adding to evidence of budding inflationary pressures as the economy reopens and demand strengthens. The consumer price index increased 0.6% from the prior month after a 0.4% gain in February, according to Labor Department data Tuesday. A jump in the cost of gasoline accounted for almost half the overall March advance. The median estimate in a Bloomberg survey of economists called for a 0.5% rise. Excluding volatile food and energy components, the so-called core CPI increased 0.3% from a month earlier, the most in seven months and reflecting rising rents and auto insurance.
