Dollar slips against dong

Vietcombank sold the greenback at VND26,377, a 0.01% dip from Tuesday. The currency went up 0.35% to around VND27,031 on the black market.

The State Bank of Vietnam reduced its reference rate by 0.01% to VND25,121.

Globally, the U.S. dollar held steady on Wednesday but was headed for its biggest annual drop since 2017 as interest rate cuts, fiscal worries and erratic trade policies under U.S. President Donald Trump cast a shadow on currency markets in 2025, Reuters reported.

Many of those worries are likely to remain in 2026, suggesting the dollar's dire performance could extend and underpin the behavior of some of its rivals that have made significant gains this year, including the euro and sterling.

The dollar index, which measures the U.S. currency versus six other major units, was at 98.228, holding onto its overnight gains. The index has declined 9.5% in 2025 while the euro gained 13.5% and the pound surged 7.6%.

The euro was steady at $1.1747 and the pound last bought $1.3463 on the last trading day of the year. Both are poised for their biggest yearly gains in eight years.

The yen was steady at 156.35 per U.S. dollar, slowly grinding away from the levels that brought intervention worries and severe jawboning from officials in Tokyo.
