Abstract:
This thesis examines the impact of banking regulation, external governance and bank-specific variables on commercial and savings bank performance, as estimated by efficiency and financial indicators, in the Asian market, between 2000 and 2012. Furthermore, the thesis analyses the effect of deposit diversification and insurance on the bank's liquidity risk tolerance in G7 and BRICS countries. It further investigates the impact of expected government support on bank risk-taking in China. Firstly, we examine the impact of Credit Rating Agencies (CRAs) on bank performance in general, and in particular on how this impact can be moderated by the strict regulation of banking criteria and the quality of investor protection embedded in different institutional environments. We find that CRAs enhances bank performance. CRAs as the flexible governance power, their positive monitoring impact is further enhanced by the quality of investor protection but mitigated by the inflexible and strict banking regulations. Secondly, this research investigates the impact of market power and revenue diversification on bank performance and stability. We find that market power could not only improve banking performance, but also increase individual bank fragility in an emerging market. Although revenue diversification reduces bank efficiency, it improves individual stability. Thirdly, we study the relationship between liquidity risk, deposit diversification and insurance in 12 countries during the period 2005-2014. We capture liquidity risk by focusing on the unfunded loan commitments. We find that higher diversification in the deposit base can reduce the impact of liquidity demand risk during the crisis by decreasing the cost of funding, increasing the funding inflow, maintaining the total amount of loan lending and enhancing the liquid ratio. Additionally, the results suggest that although deposit insurance has a positive impact during the crisis, its effect cannot mitigate the liquidity demand risk. Fourthly, this research examines the impacts of expected government support on bank risk-taking behaviour, and in particular how its impact can be stronger in state-owned and large banks. We find that the willingness and capacity of government support enhance bank's risk-taking behaviour through increasing non-performance loan as well as doubtful loan, and decreasing Z-score as well as liquid ratio. This moral hazard problems are further enhanced in state-owned banks and large banks. Finally, we outline our conclusions along with the limitations of this research and a plan for any future work.
