Vietnam's State Bank has set record daily reference rates for the dong against the dollar, and commercial bank USD/VND quotes have also surged. The central bank attributed the moves to negative news in US-China trade talks and the yuan's depreciation since late April.
Analysts described the rise as largely psychological.
Dong weakness raises import costs for Vietnamese feed and livestock buyers, but the effect on global feed grain prices is indirect. The main price channel is the yuan's slide tied to trade tensions.
