Effects of the Real Effective Exchange Rate Volatility on the Trade Balance, The Case of Vietnam for Sutainable Development Goals

Objective: The objective of this study is to analyze the impact of exchange rate volatility on the trade balance of Vietnam. Analyzing and evaluating the degree of exchange rate fluctuations of the VND from the first quarter of 2000 to the second quarter of 2019. Then, proposing the orientations and some solutions to regulate the exchange rate to ensure the trade balance surplus in the near future. Method: Exchange rate fluctuation is the conditional variance or unconditional variance or standard deviation of the base rate. Auto Regressive Conditional Heteroskedasticity (ARCH) model was used to calculate real effective exchange rate fluctuations in VND. The study also uses Ordinary Least Square regression (OLS) method to evaluate the impact of exchange rate volatility on Vietnam's trade balance. Results and Discussion: The results show that a stable long-term equilibrium relationship exists between exports. Quantitative results show that exchange rate volatility have a positive impact on exports but have not yet shown a clear impact on Vietnam's imports. The paper also points out that in addition to the exchange rate fluctuations, many other factors such as foreign income, domestic income, trade conditions ... could also affect the trade balance. Research Implications: To achieve the trade balance surplus, the proposed solutions need coordination among ministries and agencies. Finally, the flexible control of State Bank on exchange rate volatility will enhance Trade Balance of Vietnam.
