HSBC last week stated that the inflation in Vietnam remains under control. The bank revised down its forecast on the country's inflation this year to 3.5% from the 3.7% it predicted in May due to stable domestic food prices.
While the current inflation rate remains below the State Bank of Vietnam's 4 percent target, the bank expects persistent high energy prices will continue to push overall prices up.
