    Risk, Liquidity, and Performance: Evidence from the Commercial Banks in Bangladesh

    No full text
    Research Originality: This study examines the interplay between bank risk, liquidity, and profitability in Bangladesh\u27s banking sector. Using a fresh approach, it shows their combined impact on stability and growth in emerging markets. It provides practical insights for banks to effectively manage these factors and achieve long-term resilience. Research Objectives: The study aims to investigate the interconnected influence of non-performing loan ratios and liquidity levels on profitability, and to analyze the effects of total asset growth, loan growth, and cost-to-income ratios on these dynamics. Research Methods: The study used a panel dataset of 31 listed commercial banks from 2012 to 2022. Ordinary Least Squares (OLS) regression was primarily employed, followed by Prais–Winsten regression with corrected standard errors (PCSEs) for correlated panels to validate the findings. Empirical Result: The research indicates that liquidity (LIQ) has a positive impact on profitability, with the net interest margin (NIM) being significantly influenced by non-performing loans. The control variable, SIZE, also showed statistical significance in performance. Implications: This study highlights the significance of asset quality, liquidity management, loan composition, and operational efficiency in determining bank profitability, providing valuable insights for bank managers and policymakers in emerging economies seeking to enhance their financial performance.

    Non-performing loans (NPLs) and non-performance: evidence from South Asian banks

    No full text
    This paper examines the consequences of banks’ performance on bank risk. The paper forms a theoretical model and delivers empirical evidence to identify that banks suffer in performance as the loans become bad. Using panel data from a sample of five (05) South-Asian emerging economies from 2011 to 2019, we have found that the banks are highly influenced by the development of non-performing loans (NPLs). We have primarily used Return on Asset (ROA) followed by Return on Equity (ROE) as a substitution to the performance of the banks and NPL as the proxy of bank risk. Simultaneous regression applying 3sls finds that Non-Performing Loan (NPL) hinders banks\u27 growth, negatively affecting their profitability

    A NOVEL TAXONOMICAL DESCRIPTION OF FIVE NEW SPECIES OF ACEPHALINE GREGARINES (PROTOZOA: APICOMPLEXA: GREGARINOMORPHEA) OF THE GENUS Monocystis STEIN, 1848 FROM EARTHWORMS OF WEST BENGAL, INDIA

    The present communication is devoted to describe five new species of acephaline gregarines (Apicomplexa: Gregarinomorphea) of the genus Monocystis namely Monocystis elliptoidum sp. nov., Monocystis pontoscolexae sp. nov., Monocystis dolium sp. nov., Monocystis lomentum sp. nov., and Monocystis asmati sp. nov. have been found from the seminal vesicles of earthworms Metaphire posthuma, Pontoscolex corethrurus, Eutyphoeus waltoni,  Eutyphoeus orientalis, and Perionyx excavatus respectively. Monocystis elliptoidum sp. nov. is characterized by elliptoid trophozoites, rounded nucleus, orbicular gametocysts and rhomboid oocysts. Monocystis pontoscolexae sp. nov. have elongated, obpyriform-shaped trophozoites, rounded nucleus, fusiform shaped gametocysts and fusiform oocysts. Monocystis dolium sp. nov. is characterized by doliform trophozoites, rounded nucleus, orbicular gametocysts and fusiform oocysts. Monocystis lomentum sp. nov. have lomentiform shaped trophozoites, rounded nucleus and fusiform oocysts. Trophozoites of Monocystis asmati sp. nov. are obpanduriform, nucleus rounded and oocysts fusiform. The relationship of these Monocystis sp. nov.  with their closely related species have been presented and their diagnoses were also discussed using morphometrics

    Industry-Specific and Macroeconomic Determinants of Non-Performing Loans: A Comparative Analysis of ARDL and VECM

    No full text
    With the growth of an economy, the banking industry expands and the competitiveness becomes intense with the increased number of banks in the economy. The objective of this research was to discover the influence of industry-specific and macroeconomic determinants of non-performing loans (NPLs) in the entire banking system of Bangladesh. We performed an analysis for the period from 1979 to 2018 by an autoregressive distributed lag (ARDL) model and checked the robustness of the results in the vector error correction (VEC) model. The outcomes of this research suggest that both industry-specific and macroeconomic factors influence NPLs significantly. Among the industry-specific determinants, bank loan growth, net operating profit, and deposit rates negatively impact NPLs with statistical significance while bank liquidity and lending rates have a significant positive affiliation with NPLs. Gross domestic product (GDP) growth and unemployment, among the macroeconomic variables, have a negative connection with NPLs. Whereas, domestic credit and exchange rates have a significant positive association with NPLs. The contribution of this research is that the outcomes found by means of econometric models can be used for predicting and measuring NPLs in upcoming years, not only for Bangladesh but also for developing and emerging economies. Individual banks, as well as the banking sector, by and large, can get a guideline from this research

    Surveys of acephaline gregarines infesting earthworms from Kalyani of Nadia districts of West Bengal, India revealed the occurrence of a new species of Monocystis Stein, 1848. Monocystis levinei sp. nov., found in the coelomic fluid of the earthworm. Trophozoites of M. levinei sp. nov. are elongated in shape, 145.0–175.0 (163.0±1.5) µm x 18.0–43.0 (29.0±1.1) µm with a prominent taillike protrusion at the posterior end, measuring 7.0–10.0 (7.9±7.9) µm x 1.5–3.1 (1.8±2.1) µm and rounded nucleus, measuring 14.2–26.3 (22.3±7.3) µm x 18.4–30.5 (26.4±2.6) µm. Gametocysts are ovoid in shape ranging from 130.0–163.0 (152.0± 0.4) µm, whereas oocysts are navicular in shape, ranging in size from 8.9–12.0 (10.4±1.0) µm x 5.2–7.3 (6.9±0.5) µm.</jats:p

    Exploring the Drivers of Bank Risk in State-Owned Commercial Banks: Evidence from Bangladesh

    No full text
    This paper investigates the factors that form bank risks in Bangladeshi state-owned banks. As a representation of bank risk, non-performing loans have been considered the dependent variable for this study. The relevant data have been extracted from six state-owned banks in Bangladesh from 2013 to 2022. The final dataset consists of 60 firm-year observations. The ordinary least square (OLS) regression with robust standard errors model is utilized to find the relationship of bank risks with determinants like asset size, efficiency, liquidity, profitability, leverage ratio, capital adequacy ratio, and loan to asset ratio. The findings say that bank size and loan-to-asset ratio have a highly significant positive relationship with bank risk, whereas profitability, capital adequacy ratio, and bank efficiency have a significant negative association with bank risk. On the other hand, leverage and liquidity are negatively and positively correlated with no statistical significance. To check the study\u27s robustness, another proxy of bank risk, loan loss provision has been used and the results are almost similar. State-owned banks operate in every economy with a different mindset than the general commercial banks. Hence, policymakers should take necessary initiatives based on this study to bring down the high bank risks in state-owned banks in Bangladesh
