The U.S. dollar gained against the Vietnamese dong on the black market Saturday morning.
Unofficial exchange points sold the greenback 0.36% higher at VND27,970. Vietcombank kept its rate unchanged at VND26,355.
Globally the dollar rose on Friday and was on course for its strongest monthly gain in almost a year, buoyed by safe-haven demand as the Middle East war intensifies and hopes fade for de-escalation, Reuters reported.
The yen was particularly under pressure, falling in afternoon trading to its weakest since July 2024 and raising the possibility of currency market intervention by the Japanese authorities.
Safe-haven flows underpinned the dollar, which has also been lifted by rising expectations for a U.S. rate increase this year. The dollar index rose 0.3% to 100.17, up 2.57% so far in March and on course for its best monthly showing since July 2025, when it rose 3.4%.
Against the dollar, the yen fell 0.34% to 160.35 yen, crossing the 160 yen level for the first time since July 2024, when Japanese officials last intervened to prop up the currency.
