Mr. Ngo Dang Khoa, head of forex market and bond department of HSBC, said that when FED started increasing the dollar rate, loan interest rate would increase and capital would be withdrawn from developing markets to flow back to the US to enjoy the rate hike.
That will put developing markets including Vietnam under the pressure of their currency devaluation compared to the US dollar amid the already influence of the November US presidential election, he added.
In that context, the interest rate on Vietnamese dong must be kept reasonable to ensure its attractiveness, he said.
The dollar interest rate increase together with questionable trade polices of the US will create market instabilities so businesses should have suitable measures to avoid risks, he advised.
