The U.S. dollar rose against the Vietnamese dong on the black market Thursday.
Unofficial exchange points sold the greenback 0.34% higher at VND26,410.
Vietcombank kept its rate unchanged at VND26,402.
Globally the dollar traded near a two-month high on Thursday as renewed Gulf hostilities sapped risk appetite, while traders were alert to the possibility of intervention as the Japanese yen hovered near the key 160 level, Reuters reported.
The euro rose 0.1% to $1.161. A Reuters poll showed that the European Central Bank is set to raise its deposit rate to 2.25% on June 11 to curb inflation. The British pound also climbed 0.1% to $1.343.
The dollar index, which measures the greenback against major peers, was little changed at 99.46, just below the two-month high of 99.56 reached in the previous session.
