The Hanoi Statistics Office announced on May 21 that the capital city's CPI showed a month-on-month increase of 0.12% over 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 many commodity prices up, especially transport items, which jumped 1.06% since last month.
Housing, electricity, tap water, fuel and building materials jumped 1.44% in the last month because of the rising price and demand for electricity and tap water in the summer, the office said.
Other goods also showed growth - 0.47% for drink and tobacco; 0.3% for garments, hats and footwear; and 0.28% for cultural, entertainment and tourism services.
Only restaurant and catering services had a price reduction, down 0.43% compared to April.
In contrast to the CPI, the price of gold in Hanoi continued its decline, dropping0.13% in the last month, and the price of the US dollar went up 0.44% against last month.
The Ho Chi Minh City Statistics Office said the city's CPI only had a slight increase of 0.3% over April.
Goods with price growth included garments, hat and footwear up 0.1%; home appliances up 0.02%; transport services up 1.05%; and cultural, entertainment and tourism services up 0.07%.
Housing, electricity, tap water and fuel jumped 2.18% against last month because of the new electricity rates and increase in demand due to the hot summer weather.
