Whither competition in Malaysia’s banking industry ex post a restructuring

The purpose of this paper is to report how banking competition has fared ex post a major consolidation exercise completed during 2002-2004, which led to a complete restructuring of the sector in Malaysia. Nothing is known about the competitiveness of banking system ex post a major consolidation of banks in any country including Malaysia, a middle-income economy.

The authors apply two models, the Panzar and Rosse (1997) and the Lerner index (1934). The two competitiveness measures are quite refined, well received by researchers, but has yet been applied to measure banking sector competitiveness of a middle-income country to characterize post-merger behavior using post-global-crisis data set. The data were complemented by documentary analysis, including brand documents, descriptions of internal processes and copies of employee magazine articles.

The results indicate that, after 11 years of consolidation, the banking sector is not operating under perfect or monopolistic competition. Malaysia’s banking industry continues to benefit the charter holders at increasingly lower level because a cartel-like environment still provides trade-off of competition costs before 2002/2004 with the costs from a cartel-like industry structures now. There is only a weak evidence that, in recent years, the banking sector is moving toward more competition.

The chosen area of research is to test the response of the banking sector ex post consolidation after a crisis. It enables researcher to compare results with those of other countries and may not be generalizable.

The findings reported in this study using corroborating measures for the first time, appear to suggest increasing concentration from consolidation may lead to the undesirable cartel-like industry structure where the exercise of market power in the name of stability may not be welfare promoting.

This paper fulfills an identified need to study how the banking sector has performed ex post consolidation after a crisis.
