Vietnam central bank lifts USD/VND rate as US‑Iran tensions rise

On 9 July 2026 the State Bank of Vietnam raised its reference USD/VND rate by five dong to 25,211, and on 10 July it added three more dong to 25,214. Commercial banks responded by increasing both buying and selling USD rates; for example, Vietcombank’s USD buying price moved to 26,081‑26,111 VND and its selling price to 26,471 VND.

The global US dollar index slipped modestly, with the USD‑Index falling to 100.99 and then 100.94, reflecting a slight weakening of the greenback after a brief rally. The move comes amid renewed US‑Iran hostilities, including Iranian strikes on US‑linked military infrastructure in the Gulf and U.S. retaliatory actions, which have revived concerns about regional stability.

Domestically, inter‑bank USD transaction volumes fell, totaling about 772.9 billion VND for the week of 29 June‑3 July, roughly 7 billion VND less than the prior week. In the United States, Federal Reserve officials signaled heightened inflation worries and an increased probability of a 25‑basis‑point rate hike at the July meeting, with a 30.5 % chance of an increase, up from 26.7 % previously.
