Prices paid by US consumers rose in May by more than forecast, extending a months-long buildup in inflation that risks becoming more established as the economy strengthens.
The consumer price index climbed 0.6% from the prior month after a 0.8% jump in April that was the largest since 2009. Excluding the volatile food and energy components, the so-called core CPI rose by a larger-than-forecast 0.7%, according to Labor Department data Thursday.
