Consumer price index (CPI) in May rose 0.18 percent against last month, despite recent increases in petrol price and minimum salary, announced the General Statistic Office (GSO) on May 24.

The index this month represented a year-on-year increase of 8.34 percent. With this slight rise, the country’s CPI in the first five months rose 2.78 percent against December 2011 level.

Nine out of 11 groups of commodities saw price hikes ranging from 0.33 percent to 3.09 percent. Goods and services experienced the highest price rise while pharmaceuticals and health services saw the lowest price increase.

Two groups of commodities that enjoyed price falls were restaurants and catering services, and housing and building materials.

According to Head of the GSO’s Price Department Nguyen Duc Thang, the slight CPI increase in May was attributable to declining prices of restaurants and catering services, which account for 40 percent in the goods basket.

In addition, construction material producers had to lower the prices of their products to reduce stockpiles and increase competitiveness, he said, adding that the reduction in gas prices also contributed to reducing the CPI rise this month.

In May, the domestic gold price decreased by 2.17 percent against the previous month following a declining world trend.

Meanwhile, the US dollar saw a month-on-month increase of 0.06 percent.-VNA
