It was the first tranche of 2 trillion dong in bonds the government planned to issue this year.
The bonds, which carry an annual coupon of 8.52 percent and a maturity of 5 years, were swiftly bought by banks and securities firms, said the Tuoi Tre (Youth) newspaper.
The state-run Vietcombank and semi-private Sacombank bought 300 billion worth of the bonds each. The Ho Chi Minh City branch of BIDV bank took 100 billion and the remainder went to three securities firms.
Last year, the city, Vietnam's commercial hub, raised 2 trillion dong in the first issuance of such debt, which were used to finance infrastructure development projects.
