Purpose The purpose of this paper is to investigate the impact of income diversification on the financial performance of commercial banks in Vietnam over the period 2007–2017. It then provides additional analysis to examine whether the diversification–performance nexus is conditioned upon bank experience and ownership structure. Design/methodology/approach The financial information of each bank were manually collected from bank annual reports. In the empirical model, a number of modern econometric techniques, including panel OLS with fixed effects and a two-step system GMM estimator, were utilised to achieve the research objectives. Findings The empirical results show that income diversification has a positive impact on banks’ performance. However, the effect varies across different types of banks. Specifically, the authors find that while diversification benefits state-owned and foreign banks, it exhibits a detrimental effect on the financial performance of other non-state owned domestic banks. In addition, the authors further find that the positive impact of diversification is more prominent for banks with more experience in the market. Originality/value This study is among the first to empirically investigate the relationships between income diversification and the financial performance of commercial banks in Vietnam. In this sense, the findings of this study could draw important inferences for researchers, policy makers and bank managers towards more appropriate diversification strategies, to ensure the safety and soundness of the whole banking system.

PurposeThe purposes of this paper are twofold. First, it analyses the income structure in cooperative financial institutions and examines how traditional and non-traditional incomes are related. Second, it evaluates whether increasing diversification towards non-traditional incomes facilitates or hampers the benefits of financial cooperative owners.Design/methodology/approachData are collected from over 3,100 US credit unions over the period of 1994–2016. A number of modern econometric techniques are employed throughout the analysis, including the use of panel fixed effect, generalised method of moments (GMM) and two-stage least square (2SLS) methodologies.FindingsUsing US credit unions as the empirical setting, the empirical results reveal that the expansion of traditional income leads to a corresponding increase in income from non-traditional activities. However, an increasing reliance on non-traditional income causes a significant drop in interest margins. The authors also find that the extent to which income diversification affects owner benefit varies across credit union types and period of time. While income diversification negatively affects owners' benefits in single common bond credit unions, it has no significant influence on multiple common bond and community credit union owners' benefits. Third, diversification can be beneficial during crisis time, but can be detrimental to owner benefit during normal time.Originality/valueThis paper provides some of the first empirical investigations on the diversification strategy of cooperative financial institutions. Therefore, the results offer significant policy implications for policymakers and market participants on whether financial cooperatives should diversify or specialise.

Although the public sector is seen as the main party responsible for taking action on climate change and sustainable development, private commercial banks are in a unique position to support or shift the funding focus on green investment. By employing a qualitative research approach based on six commercial banks, this paper aims to investigate the current practices of how commercial banks are contributing to advance green business initiatives. Accordingly, this research examines and identifies the facilitators and challenges in domestic and foreign commercial banks in Vietnam which support green business initiatives. In addition to addressing the recent calls for the investigation of the role of commercial banks in facilitating green finance, our study expands the emerging literature by demonstrating the current efforts of Vietnam's commercial banks in fostering green finance during the Covid‐19 pandemic.

This paper investigates the effect of monetary policy on liquidity creation of commercial banks and if the effect is conditional on bank size. The paper uses a dataset covering 23 Vietnamese commercial banks during the period 2007-2017 collected from various sources including State Bank of Vietnam, International Monetary Fund, SNL Financial database (provided by SNL Company), Vietnam General Statistic Office and banks' annual reports. Different econometric techniques are employed to analyse the data. Obtained results indicate that a contractionary monetary policy could lead to a decrease in bank liquidity creation. This result is less pronounced with larger banks. In particular, among three monetary policy instruments employed in Vietnam, an increase in the base rate is significantly associated with a contraction in bank liquidity creation; open market operations may have a marginal impact while required reserve ratio is ineffective because of its unchanged value throughout the period of the study. This paper is among the first, providing an insight into each monetary policy instrument's role in influencing bank liquidity creation in the context of an emerging economy.
