Abstract:
Risk management is an essential element of bank and financial intermediation. Failure to
effectively evaluating and managing the risks factors may lead to losses that threaten the health
of the bank and the sustainability of the entire financial system. Most of Bangladesh’s
commercial banks have their own guidelines and procedures for managing the core risk areas i.e.
Credit Risks, Market Risks, Operation Risk and Liquidity Risk to ensure the bank’s sustainable
development and manages all risks factors.
This study analyzes the impact of risk management factors on the financial performance of
commercial banks operating in Bangladesh both in the short run and long run considering
internal and external control factors. This study also review the existing risk management related
policies, guidelines and practices in commercial banks operating in Bangladesh. After reviewing
risk management related theories, Bangladesh Bank policies and guidelines related to risk
management and empirical literatures, this study identify dependent variables as return of asset
(ROA) and return on equity (ROE) as proxy of financial performance and independent variables
including log of non-performing loan ratio (LnNPLR) as proxy of credit risk, log of net interest
margin (LnNIM) as proxy of interest rate risk, log of foreign exchange gain/ losses (LnFexGL)
as proxy of foreign exchange risk (both are component of market risk of the banks), loan to
deposit ratio (LDR) as proxy of liquidity risk and log of cost to income ratio (LnCIR) as proxy of
operational risk. This study include proxy variable related to type of banking operations in
Bangladesh like Islamic banking or Conventional banking in to the econometric models.
Gradually, it does include Herfindahl–Hirschman Index (HHI) as proxy of within banking
industry concentration control variable and GDP Growth Rate & Inflation Rate as proxy of
macro-economic variables into the econometric models. The econometric models have been
developed to examine both long run and short run effect of the independent variables on the
dependent variables to establish the research questions.
The secondary data has been accumulated from the annual reports of all the commercial banks
operating in Bangladesh during the study period, i.e. from 2014 to 2019. After panel data set
validation, this study used STATA – 12 version to test long term and short term impact of
dependent variables on the independent variables to check the impact of risk factors on the
financial performance of local commercial banks operating in Bangladesh during the period. To
check the long run effect of the dependent variables on the independent variables, this study
examine the output of both random effect GLS regression model and fixed effect regression
model for all the econometric models. Hausman Test result has been used to determine the
appropriate model for analyzing long run effect of the econometric models. Two step system
GMM model has been used to check the short run impact of the dependent variables on the
independent variables for all the econometric models.
The empirical output of first econometric models shows that, the bank specific risk factors, credit
risk and operational risk has negative impact of both the dependent variables, i.e. financial performance of commercial banks operating in Bangladesh during the study periods, both in the
long run and short run, considering bank specific control factors only, which is also in line with
the statistical assumption of this study. The other risk factor, market risk (including both interest
rate risk and foreign exchange risk) has positive impact of both the dependent variables, i.e.
financial performance of commercial banks operating in Bangladesh during the study periods,
both in the long run and short run, considering bank specific control factors only, which is also in
line with the statistical assumption of this study. But, the other risk factor, liquidity risk showed
different behaviors in different part of this study. Liquidity risk has negative correlation with
both the dependent variables, i.e. ROA & ROE in the long run while have positive correlation
with ROA and negative correlation with ROE in the short run. When this study included within
banking industry concentration control proxy variable ―HHI‖ in to the second econometric
model, the liquidity risk behaves differently, i.e. liquidity risk showed positive correlation with
both the dependent variables, i.e. ROA & ROE, both in the long run and short run, which is also
in line with the statistical assumption of this study.
However, when this study included macro-economic control variables ―GDP Growth rate‖ and
―Inflation rate‖ into the third econometric model along-with within banking industry
concentration control proxy variable ―HHI‖ and bank specific control variable ―Bank Size‖,
foreign exchange risk showed negative correlation with ROA but have positive correlation with
ROE in the long run while has positive correlation with both ROA & ROE, i.e. financial
performance of commercial banks operating in Bangladesh in the short run. The foreign
exchange risk behaves differently in the long run with two dependent variables, i.e. ROA and
ROE due to different types of dividend payout policies and capital management policies of the
commercial banks operating in Bangladesh, which may have influence on the ROE ratio
calculation techniques for the Banks. The correlation between other risk factors and profitability
of the banks are in line with the statistical assumption of this study considering all the internal
and external control factors into the model.
After reviewing all the outputs of the econometric models, it has been observed that, Banks’ can
manage their credit risk and operational risk efficiently through implementation of prudent
policies, guidelines and ensure proper monitoring, compliances to minimize losses as well as
improve their financial performance. But there may have influence of some external factors on
the liquidity risk and market risk of the banks. Which has been analyzed and empirically tested
through examined econometric models of this study, i.e. bank should analyzed other external
factors like banking industry concentration and macro-economic variables like GDP Growth
Rate and Inflation Rate carefully while managing the liquidity risk and market risk in addition to
all the bank specific risk factors for commercial banks operating in Bangladesh during the study
period. Based on the findings, this study made some recommendation for the stake holders of the
commercial Banks operating in Bangladesh, which will be effective to manage its risk factors as
well as financial performances.
