Dollar declines on black market

The dollar declined by 0.04% to VND26,430 at unofficial exchange points.

The State Bank of Vietnam lowered its reference rate by 0.02% to VND24,962.

The U.S. dollar edged lower on Wednesday, extending a two-day slide against major peers, as President Donald Trump failed to convince Republican holdouts to back his sweeping tax bill, Reuters reported.

The dollar declined 0.14% to 144.31 yen early in Asia's day, and slipped 0.22% to 0.8264 Swiss franc.

The dollar index, which measures the U.S. currency against those four peers and two other rivals, edged down 0.03% to 99.938, following a 1.3% two-day decline.

"Tariff rates are now lower, but not low, and the same can be said about recession risks in the U.S.," Goldman Sachs analysts wrote in a research note.

"But as recession risks have compressed, risks from higher rates are growing," they said. "The U.S. still faces the worst growth-inflation mix of the major economies, and as the fiscal bill makes its way through Congress, eroding U.S. exceptionalism is proving - literally - costly at a time of large funding needs."

This leaves wider paths to a weaker dollar and a steeper U.S. Treasury curve, they added.
