THB/VND: what to know
The THB/VND rate shows how much VND you get for 1 THB. Right now, 1 THB buys 775.9433 VND at the mid-market rate. In the other direction, 1 VND is worth 0.00128875 THB.
In the short term THB is driven mainly by tourism and trade flows, while VND responds to exports and central-bank policy.
The Thai Baht (THB) is issued by Bank of Thailand. “Baht” was historically a unit of weight for silver. The Vietnamese Dong (VND) is issued by State Bank of Vietnam. The đồng has very high denominations — notes go up to 500,000.
Use this mid-market figure as your benchmark: compare it with the rate your bank or broker quotes, and the difference is the margin you would pay.
