Dollar gains over dong

Vietcombank sold the greenback at VND26,150, a 0.04% gain from the weekend. The currency was mostly firm at around VND26,475 on the black market.

The State Bank of Vietnam reduced its reference rate by 0.02% to VND24,945.

Globally, the dollar firmed against safe haven peers on Monday as signs of progress in U.S.-China trade talks boosted hopes a global recession might be avoided, though specifics were still sorely lacking, Reuters reported.

The euro dipped 0.2% to $1.1224 and the dollar index edged up 0.2% to 100.60. The dollar added 0.4% on the safe haven yen to reach 145.90, though it was off an early five-week peak of 146.31.

The dollar also dipped 0.2% on the offshore Chinese yuan to 7.2278, and back toward last week's low of 7.1846.

Data on U.S. consumer prices for April due this week could offer an early hint of the impact of import levies on inflation, while retail sales are seen flatlining in April after a pre-tariff surge the month before.

"We expect it will not be until the May CPI data are out before we see broad evidence of tariffs showing up in inflation data," analysts at ANZ wrote in a note.

"In this regard, we think June is too early for the Fed to cut rates and maintain our view that Q3, and most probably September, is a more realistic time frame," they added. "That would give the opportunity to observe the impact of higher tariffs on both the price level and inflation persistence."
