The effect of mergers and acquisitions on the efficiency of Vietnamese banking systems during restructuring period
Abstract
Since 2011, the Vietnamese banking system has performed many M&A deals.
Some small banks which had weak competitiveness and experienced operating activities
risk, were on the verge of bankruptcy, and had been acquired by potential financial
institutions. Although M&A transactions are famous for numerous advantages which are
brought back for banking industry, most banks still have not actively participated.
Therefore, gaining more information about how M&A section has changed our banking
system is essential for providing suitable implications and developments for the future
plans. This report first aims to investigate the efficiency level of 30 Vietnamese
commercial banks during 2011-2019 period, following intermediation and operating
approach, and using Bootstrap Data Envelopment Analysis (DEA) to measure the
efficiency scores. The paper shows that banks have higher rate of efficiency in
intermediation aspect compared to operating aspect. Next, applying Robust Truncated
Regression, the report shows that M&As negatively affect on banking efficiency, and has
no significant interaction with other variables. Meanwhile, a set of explanatory variables
following CAMELS standards can increase the efficiency proportion.
