Triggered by the petrol price adjustment on May 20, the price bracket saw the sharpest rise in transportation, soaring 3.58% from May.

Last month, the Hanoi Statistics Office announced that the capital city's CPI showed a month-on-month increase of 0.12% from April and a year-on-year surge of 0.93%.
The office said the increase was mainly due to a surge in petrol prices since May 5 that pushed a number of commodity prices up, especially transport prices, which jumped 1.06% from April.
Meanwhile, the HCM City Statistics Office also reported 0.62 % growth in the city's CPI for June and a year-on-year increase of 0.78 %.
The rise was attributed to the impact of strong increases in the transport and pharmaceutical-healthcare sectors. Of this, transport rose 3.94 % over May due to the petrol price adjustment.
Surges in the city this month include pharmaceuticals and healthcare (3.98 %), transport 3.94 %, food and catering service 0.32 % , drink and tobacco (0.12 %), garment and footwear (0.03 %) and household appliances (0.01 %) and culture and entertainment (0.39 %).
