Dollar rises against dong

Vietcombank sold the dollar at VND25,610, up 0.12% from the weekend. The greenback was firm at around VND25,720 on the black market.

The State Bank of Vietnam hiked its reference rate by 0.06% to VND24,577.

Globally, the yen rose on Monday in a boost from upbeat Japanese GDP data, while the Australian and New Zealand dollars held broadly steady ahead of policy decisions later in the week, Reuters reported.

The yen was last 0.27% stronger at 151.94 per dollar, reversing losses from earlier in the session after data on Monday showed Japan's economy expanded faster than expected in the fourth quarter - cementing the case for more rate hikes from the Bank of Japan (BOJ) this year.

In the broader market, the dollar was struggling to recoup its losses after a selloff on the back of Friday's weak U.S. retail sales data and as investors cheered the delay in the implementation of Donald Trump's reciprocal tariffs.

Geopolitics also remained in focus with reports that talks aimed at ending the Russian-Ukraine conflict will begin in Saudi Arabia this week, though the participants are not entirely clear.

That kept the euro supported, with the common currency inching closer toward the $1.05 level and last at $1.0487, while sterling was little changed at $1.2582.

The dollar index last stood at 106.79, after tumbling 1.2% last week.
