Navigating banking transitions: insights into competition and stability from Vietnam’s experience

Abstract

ABSTRACT This article investigates the relationship between bank competition and stability within a transitioning economy, focusing on Vietnamese banks from 2007 to 2018. Set against the backdrop of a transformative banking landscape post the collapse of the socialist bloc, the article utilises the Lerner Index to measure bank competition. The Z-score is used as a measure of bank stability. Panel fixed effects and difference GMM estimations suggest that heightened competition correlates positively with bank stability. Notably, these dynamics hold true even after omitting state-owned banks, signifying that government-controlled banks do not exclusively drive the observed relationships. Policymakers, hence, face the crucial task of balancing liberalisation efforts with safeguarding bank stability and emphasising the need for robust risk management and strong corporate governance in transitioning economies dominated by public ownership. This article thus offers valuable insights for policy refinement in similarly poised nations.
