Determinants of Net Interest Margin of Commercial Banks in Vietnam
Abstract:This study provides an insight into the determinants of net interest margin (NIM) of commercial banks in Vietnam during the recession period. We employ secondary data collected from published audited consolidated financial reports of Vietnamese commercial banks from 2008, the year marking the outbreak of the global financial crisis, to the end of 2012. Altogether, the data constitute 175 panel-data observations. The regression using the ordinary least squares method yields the result that operating expense, management quality, risk aversion, and inflation rate have a positive effect on NIM, while the banking sector’s market concentration affects NIM negatively. Afterwards, some policy implications are derived from those findings to mitigate and put NIM under control, so that the efficiency of the financial intermediary system can be developed.
