HANOI, Aug. 23 (Xinhua) -- Vietnam has mobilized 104,261 billion Vietnamese dong (over 4.5 billion U.S. dollars) from government bonds so far this year, realizing 37.5 percent of the annualized target, the Hanoi Stock Exchange said on Thursday.

On Wednesday, the State Treasury of Vietnam raised 4,100 billion Vietnamese dong (nearly 178.3 million U.S. dollars) from auctioning government bonds with terms of 10 years and 15 years on the Hanoi Stock Exchange.

This year, government bonds of all terms have been offered at higher annual interest rates amid lower volumes purchased.

The government bonds issued in 2017 had average maturity of 13.52 years and average annual interest of 6.07 percent, down 0.2 percentage points against 2016, said the Treasury.
