The annual inflation rate advanced to a slightly higher-than-projected 0.64 percent in May 2017, after resuming in April the growth that had been discontinued in March 2017 (0.61 percent, against 0.18 percent). Behind this stood chiefly the step-up in core inflation and the slower negative growth of administered prices, as well as the rise in volatile food prices. The effects of these determinants were partially offset by the impact of slower annual fuel price dynamics, amid a renewed decline in the global oil price.
