The amount was mobilised from five-year bonds with an annual interest rate of 4.1%, which was 0.05% higher than that of the most-recent auction on July 16.
The auction had planned to sell VND2 trillion (US$86.63 million) worth of bonds with five-year, 10-year, and 15-year maturity. However, there were no successful bids for the 10-year and 15-year bonds.
Since the start of 2018, the VBSP mobilised VND350 billion (US$15.17 million) worth of guaranteed bonds through auctions on the HNX.
Government-guaranteed bonds are bonds issued by authorised entities to mobilise capital for investment projects as appointed by the Prime Minister.
According to the HNX, the State Treasury of Vietnam raised about VND4.4 trillion (more than US$190.7 million) in the last Government bond (G-bond) auction of June. The amount brought the total funds collected from G-bond auctions in the first half of 2018 to nearly VND74.6 trillion (US$3.23 billion).
The National Financial Supervisory Commission has predicted that the G-bond market in 2018 will see modest changes from last year thanks to the economic growth of more than 6.7% and inflation of below 4%. It expects the value of G-bonds issued this year to reach VND180 trillion (US$7.92 billion).
Last year, Vietnam sold some VND159.9 trillion, or US$7.03 billion, worth of G-bonds with average maturity of 13.52 years and annual interest averaging 6.07%, down 0.2 percentage points against 2016.
The interest rates of G-bonds have been on the rise lately, after a long period of decline throughout 2017 and the first four months of 2018.
