Gasoline prices increased sharply Thursday afternoon after inching down last week.
The popular fuel RON95 rose 6.36% to VND21,060 (US$0.85) per liter.
Biofuel E5 RON92 increased by 5.25% to VND19,840.
Regulators said that prices in the last seven days rose as a hurricane made landfall in the U.S., resulting in a spike in demand in that country, and concerns over the military conflict in the Middle East.
In the last seven days, fuel prices have increased by 7-7.9% and oils have gained 5.2-7.4%. RON95 is now at $88.2 per barrel and diesel at $90.
