Bold fuel and power price hikes recently have made the inflation in June the highest this year, new statistics found.

A statement from the General Statistics Office (GSO) said the consumer price index in June increased 0.35 percent from May, which is the highest monthly rise of the index this year.

It is 0.55 percent higher than at the end of 2014, one percent up year on year and the highest in June for the past four years.

The surge results from several fuel price increases, and the high power bills given the increasing electricity use amid hot days after the retail price was raised 7.5 percent in March.

Gasoline prices increased 18.5 percent in three occasions in May and June while diesel prices increased slightly.

GSO said fuel price hikes contributed to around 0.3 percent of the CPI increase and power use 0.04 percent.

CPI during the first half this year increased 0.86 percent over the same period last year.
