The volume of valuable paper trading remained at about 32-56 trillion VND (1.64-2.87 billion USD) from July to August.
It even climbed to 110 trillion VND (5.64 billion USD) in late June.
But the volume had fallen seven fold to 7.72 trillion VND (395.79 million USD) as of August 20.
"The reduction was very surprising," Thang Long Securities said in a report issued last week.
"It reflects the improvement in bank liquidity."
