Dollar slides against dong on black market

The greenback was down 0.04% to VND25,910 on the black market. It was firm at VND25,820 at lender Vietcombank.

The State Bank of Vietnam hiked its reference rate by 0.06% to VND24,851.

Globally, the dollar firmed a touch and other currencies held tight ranges on Wednesday as traders anxiously awaited details of U.S. President Donald Trump's tariff plans later in the day that could set the tone for markets in the near term, Reuters reported.

The euro last bought $1.0792 while sterling steadied at $1.2924, both little changed ahead of a White House Rose Garden announcement that will likely see the imposition of dramatic new duties that could upend the global trade system.

Against the yen, the dollar rose 0.15% to 149.85. While the dollar rose marginally against a basket of currencies to 104.25 on Wednesday, that comes after the greenback clocked a 3.1% fall in March, its worst monthly performance since November 2022.

Trump has for weeks trumpeted April 2 as "Liberation Day", and White House spokeswoman Karoline Leavitt said reciprocal tariffs on countries that impose duties on U.S. goods would take effect immediately after Trump's announcement.

"Markets are going to be jittery ahead of the announcement," said Carol Kong, a currency strategist at Commonwealth Bank of Australia.

"Sentiment is going to be driven by any further tariff headlines and in turn that will drive currency moves ahead of the big announcement."
