This paper analyzes the causal relationship between the banking system development and the real estate market in Vietnam from 2004:Q3 to 2018:Q4, with the use of the autoregressive distributed lag (ARDL) model as the analysis method. In Vietnam, there is no empirical study on this issue. Therefore, the paper is the first empirical evidence for the relationship between the banking system development and the real estate market in Vietnam. The research results show that the banking system development (measured through the domestic credit to the private sector) and the real estate market had a positive causal relationship in both short and long terms. In addition, the paper found a statistically significant impact of the global financial crisis on the banking system development and the real estate market in Vietnam, which is a new discovery compared with previous studies.
