Dollar dips against dong

Vietcombank sold the greenback at VND26,384, down 0.008% from Thursday. The currency gained 0.13% to VND26,925 on the black market.

The State Bank of Vietnam lowered its reference rate by 0.008% to VND25,128.

Globally, the U.S. dollar index, which measures the greenback's strength against a basket of six currencies, held steady near a two-month high at 99.37 on Friday. It is on course for a 1.7% gain, its biggest jump in a year, Reuters reported.

The yen was last steady at 153.12 per U.S. dollar in early Asian hours, hovering near its weakest level since mid-February. The Japanese currency is on pace for a nearly 4% drop in the week, its biggest decline since early October last year.

The euro last fetched $1.15635, anchored near two-month lows hit on Thursday and on pace for a 1.5% drop for the week, its sharpest decline in 11 months as the political turmoil in France weighed on the single currency.

In other currencies, the Australian dollar was 0.11% firmer at $0.6563, while sterling was at $1.33044, rooted near the two-month low it hit on Thursday.

"The recent dollar rally has gone against market positioning and prompted a partial covering of USD shorts," said Chris Weston, head of research at Pepperstone.

"There remains a high degree of scepticism that the USD can materially push through 100, a level in the dollar index that was quickly reversed in May," he said in a note.
