ABSTRACT

This study presents a comparative analysis of the key determinants of credit risk in Islamic and conventional banks in Malaysia, a country with a dual banking system. Using panel data from 16 Islamic and 25 conventional banks between 2013 and 2022, the study applies the Random Effects Model to assess the impact of bank-specific variables: size, capitalization, financing growth, liquidity, and profitability. Results indicate significant variations in how these factors influence credit risk across the two banking systems. Notably, profitability is the most influential determinant for Islamic banks, while capitalization dominates in conventional banks. These findings underscore the importance of tailored credit risk strategies and offer policy insights for improving banking stability in dual-system economies.

INTRODUCTION

Effective credit risk management is crucial for the stability of banking institutions and the broader economic landscape, as it involves assessing the likelihood of borrower defaults. Recently, Malaysia has faced economic challenges, including slow growth, rising debt levels, and increasing loan defaults, which intensify the need for robust credit risk management strategies. These phenomena can be attributed to COVID-19, followed by the war in Ukraine and unpredictable weather, all of which disrupt economic growth. This has exposed Malaysian banks to higher credit risks.

The determinants of credit risk have long been a focal point in financial literature and are recognized as key issues in banking (Jaafar, Saddam, Muhamat, Zuhairi, & Abd Aziz, 2023; Misman & Bhatti, 2020). Despite extensive research exploring various factors influencing credit risk across different financial institutions and national contexts, findings remain inconclusive, and a consensus on the definitive variables impacting credit risk is yet to be achieved.

This study addresses the gap in comparative analyses between Islamic and conventional banks regarding their determinant especially significant due to their differing adherence to financial principles. Islamic banks, adhering to Shariah law, avoid riba’ (interest) and utilize financing structures such as Tawarruq, Musyarakah, and Ijarah. In contrast, conventional banks operate on an interest-based system, offering loans and credit facilities that involve interest payments. Despite these fundamental differences, limited studies have explored how these divergent practices influence credit risk, with non-performing loans commonly serving as a primary indicator (Jaafar et al., 2023).

Furthermore, this research leverages loan loss provisioning (LLP) as a proxy for credit default risk, investigating both its determinants and its impact on lending practices and the broader economy. The regulatory environment, including the Malaysian Financial Reporting Standards (MFRS) 9 and guidelines from Bank Negara Malaysia (BNM), plays an instrumental role in shaping these practices. These regulations compel banks to undertake rigorous estimation, judgment, and modeling to predict and mitigate credit risks effectively. Techniques such as stress testing, scenario forecasting, and collateralization are also critical for assessing a bank’s resilience to credit-related challenges.

In summary, this research seeks to extend the understanding of the determinant of credit risk, specifically within the unique context of Islamic banking. The insights gained from this study will contribute to both the practical knowledge of financial institution operating in the Islamic banking sector and the academic literature on finance.

LITERATURE REVIEW

Credit Risk

Credit risk assessment is crucial in financial institutions for measuring their financial performance and controlling risk, with credit scoring algorithms widely employed to expedite credit decisions and mitigate potential risks (Ray & Luz, 2024).However, credit risk management differs between Islamic and conventional banks, with Islamic banks adhering to Sharia principles and offering distinct financing structures compared to conventional banks, which operate on an interest-based system (İncekara & Çetinkaya, 2019) .While both types of banks manage various risks, including operational and liquidity risks, Islamic banks face unique challenges due to Sharia compliance requirements and profit-loss sharing models.Previous studies have found that Islamic banks exhibit higher default risks compared to conventional banks, emphasizing the need for effective risk management practices (Koh, Eric, Banna, Hasanul, Lee & Youmkyung, 2022). Comparative analyses between Islamic and conventional banks often use non-performing loans as proxies for credit risk, while novel approaches such as modelling credit risk based on past-due days offer additional insights into default probabilities (Montes & do Nascimento Valladares, 2024). Additionally, loan loss provisioning serves as a proxy for credit default risk, with its impacts on financial performance influenced by regulation, macroeconomic factors, and bank characteristics (Ozili, 2024).

Determinant of credit risk

Several studies have empirically developed several bank-specific factors that may affect banks’ credit risk. Therefore, this study identifies five internal components: profitability, financing growth, bank size, capitalization and liquidity, as independent variables to investigate their significant influences as determinants of banks’ credit risk.

Profitability

The relationship between bank profitability and credit risk is intricate, with profitability serving as a key indicator of a bank’s operational effectiveness. Profits derived from interest on assets and service fees are crucial revenue sources, while interest on liabilities constitutes significant expenditure. Previous studies, such as Ozili (2024), underscore the significance of profitability as a metric for measuring credit risk, highlighting the intricate link between the two. Research also highlights the importance of prudent risk management practices, such as larger loan provisions, in bolstering long-term profitability. Islamic banks, constrained by Sharia principles, exhibit unique patterns in managing loan loss provisions, leveraging profitability to modulate these provisions in response to earnings fluctuations, contrasting with conventional banks’ inverse relationship between profitability and loan loss provisions. Understanding these dynamics is vital for navigating the challenges posed by credit risk and ensuring financial stability in banking institutions.

Financing growth

The relationship between loan growth and credit risk in financial institutions is multifaceted and crucial for understanding the dynamics of banking operations. While loan portfolio expansion can potentially increase credit risk by exposing banks to a wider pool of borrowers, prudent risk management practices and regulatory frameworks can mitigate these risks, as suggested by Bhowmik and Sarker (2021) and Mpofu and Nikolaidou (2018). However, empirical evidence from studies such as (Baron & Xiong, 2017; Deng, Li, & Ren, 2023)indicates that excessive loan growth may lead to asset bubbles, weakened bank solvency, and poor financial performance. Additionally, research by (Sobarsyah et al., 2020; Wu et al., 2022) highlights the nuanced relationship between loan growth and credit risk, emphasizing the role of factors such as bank size, capitalization, and economic context. Striking a balance between loan expansion and prudent risk management practices is crucial for ensuring sustainable and resilient lending practices in financial institutions.

Bank Size

Bank size plays a pivotal role in influencing loan loss provisions and profitability in financial institutions, with larger banks often exhibiting distinct characteristics and strategic features. Studies such as Hazera, Quirvan, and Triki (2017) indicate a negative correlation between bank size and loan loss provisions, suggesting that larger banks tend to make sparse provisions due to their more diversified loan portfolios and greater financial capacity for credit risk management. Conversely, Kouzez (2023) and Tharu and Shrestha (2019) assert that larger banks may also engage in risk-taking behavior, potentially leading to higher loan losses and provisions. However, Rouetbi, Ftiti, and Omri (2023) findings suggest a positive relationship between bank size and profitability, particularly in Islamic banks where larger institutions benefit from economies of scale and higher capital, contributing to enhanced performance. The nuanced relationship between bank size, loan loss provisions, and profitability underscores the importance of understanding bank-specific indicators and risk profiles in assessing banking performance (Terraza, 2015)

Bank Capitalization

Capital is a critical factor in assessing a financial institution’s ability to extend loans, with higher levels of capital enabling institutions to lend more and inspire trust among investors and consumers (Barthel, Bezzel, Krüger, Päckert, & Steinheimer, 2018). Cicchiello, Cotugno, Monferrà, and Perdichizzi (2022) find that banks with higher capital buffers tend to have fewer loan provisions and inflows, highlighting the importance of capitalization in loan provision dynamics. In Islamic banking, Sobarsyah et al. (2020) argue that strengthening capitalization is essential to promote countercyclicality in loan loss provisioning and mitigate credit risk, especially during economic downturns. However, increased capitalization may also lead to higher risk-taking behavior among bank managers to offset the cost of capital, potentially worsening financial stability (Sobarsyah et al., 2020). Additionally, (Mateev, Georgieva, & Zlatkov, 2022) highlight the influence of capital regulation and market competition on bank risk-taking, with conventional banks’ capital ratio positively impacting credit risk while Islamic banking institutions’ risk behavior is more influenced by banking competition. This underscores the importance of considering capital regulation’s differential impacts on conventional and Islamic banks in promoting financial stability and prudent risk management.

Liquidation

In the banking sector, liquidity and loan provision are interlinked yet distinct concepts, both crucial for ensuring financial stability and fulfilling obligations to stakeholders. Liquidity refers to a bank’s ability to meet short-term commitments, vital for funding loans and handling deposit withdrawals to avoid potential bank runs or collapse. Conversely, loan provisions serve as a tool for controlling credit risk by setting aside funds to cover potential losses from loan defaults. Islamic banks, as demonstrated by Rashid and Yadav (2020), have shown resilience and financial stability during crises compared to conventional banks, owing to their distinct banking models founded on Sharia principles prohibiting interest and promoting halal investments. Pop et al. (2018) argue for regulators to focus on less liquid banks due to their higher sensitivity to non-performing loans (NPLs) and systemic risk, advocating for tailored treatment based on loan portfolio size to optimize risk indicators and enhance monitoring systems. Additionally, Rashid and Yadav (2020)  stress the importance of bank liquidity in stabilizing the banking system during economic crises and urge policymakers to develop crisis management strategies centered around banks to maintain financial stability.

RESULTS AND DISCUSSIONS

Table 3  and 4 represent descriptive analysis of Islamic and  conventional bank spanning from 2013 to 2022. This study provides a comparative analysis of Islamic and conventional banks in Malaysia, focusing on credit risk, bank size, capitalization, financing growth, liquidity, and profitability. Islamic banks displayed lower credit risk and variability, while conventional banks showed higher risk levels and greater financial strength, evidenced by their superior capitalization metrics. Despite restricted access to liquidity management tools due to Shariah compliance, Islamic banks managed financing growth more effectively during economic fluctuations, demonstrating resilience in adjusting their financing loss provisions. Conventional banks, however, had higher liquidity and profitability, benefiting from broader market access. The statistical analysis confirmed the regression model’s adequacy through comprehensive tests, ensuring the study’s robustness in evaluating the financial performance differences between the two types of banks.

Panel Data Analysis

The likelihood Ratio Test is applied in this study to choose the best model between Pooled Ordinary Least Squares (POLS) model and the Fixed Effects Model (REM). The hypotheses under Likelihood Ratio Test are as follows:

H0 = POLS model is preferred

H1 = Fixed Effects Model is preferred

The Hausman specification test was conducted to compare fixed effects and random effects estimations in selecting the most appropriate model estimation (Baltagi, Bresson, & Pirotte, 2008; Hsiao & Gibson, 2003).As the random effects model assumes the exogeneity of all of the regressors and the random individual effects, the fixed effects model allows for the endogeneity of all of the regressors, as well as individual effects. Therefore, Hausman and Taylor (1981) introduced a model in which some of the regressors are correlated with individual effects. This indicates that the individual means of the strictly exogenous regressors are used as instruments for the time-invariant regressors, which are correlated with the individual effects. Therefore, the choice of exogenous regressors is a testable hypothesis.

The hypotheses statement are as follows:

H0 = Random Effects model is preferred

H1 = Fixed Effects model is preferred

In Table 6, which pertains to Islamic banking, the analysis of the Likelihood test reveals a probability value of 0.0000, indicating statistical significance below the 5% threshold. Consequently, the null hypothesis is rejected, and the Fixed Effect Model is adopted for the study. Following this, the Hausman test was performed, yielding a probability value of 0.2609, which exceeds the 5% significance level. Therefore, the Random Effect Model is deemed the most suitable for the data under consideration in this research.

For conventional bank, the Likelihood test results indicate a probability value of 0.0000, signifying that the outcome is statistically significant at a level below 5%. Consequently, the null hypothesis has been rejected, leading to the selection of the Fixed Effect Model for further analysis. Subsequently, the Hausman test yields a probability value of 0.8823, which notably exceeds the 5% significance level. Thus, the Random Effect Model is identified as the most appropriate for the data in this study.

The analysis of the determinants of credit risk in Islamic and conventional banks reveals distinct influences of bank characteristics. For Islamic banks, variables such as bank size, capitalization, and profitability demonstrate significant effects on credit risk, whereas liquidity and financing growth do not exhibit significant impacts. Conversely, in conventional banks, neither profitability nor bank size shows a significant relationship with credit risk.

Regarding the relationship between bank size and credit risk, Islamic banks display a significant but negative correlation, suggesting larger Islamic banks tend to have lower credit risk. This contrasts with conventional banks, where bank size is not significantly related to credit risk and tends to show a positive relationship, though it is not statistically significant. This pattern aligns with findings from previous research by Niu (2023), which highlighted similar trends. The difference may be attributed to the risk profiles and asset management strategies of the banks. Conventional banks, often larger, can leverage economies of scale to manage and diversify risks effectively, allowing them to engage in higher-risk credit activities without proportional increases in observed risk.

Further, the study by Majeed and Zainab (2021) explores the capitalization levels of Islamic versus conventional banks, noting that Islamic banks typically exhibit better capitalization, reflecting lower risk profiles and higher liquidity levels. Sobarsyah et al. (2020) suggest that banks can enhance their capitalization by adjusting loan loss provisions according to economic conditions, thus mitigating future credit risk.

In terms of financing growth, both bank types show a negative relationship with credit risk. Conventional banks, similar to their approach in capitalization, adjust their loan loss provisions in alignment with financing growth to manage potential risks effectively. Warninda, Ekaputra, and Rokhim (2019) found that financing growth in Islamic banks tends to decrease credit risk, potentially due to the conservative calculation methods that consider impaired financing against total financing.

The relationship between liquidity, profitability, and credit risk also varies between the two banking systems. Islamic banks show a negative correlation between these factors and credit risk, suggesting that higher liquidity and profitability correspond to lower risk. In contrast, conventional banks display a positive relationship, where increased liquidity and profitability are associated with higher credit risk, as noted by Jimoh et al. (2021). This indicates that while conventional banks may pursue higher profits through increased lending, they also face heightened financial pressure and default risk. This dynamic underscores the contrasting operational frameworks and compliance obligations of Islamic versus conventional banks, particularly in adhering to Shariah principles that prohibit investments in unethical and interest-based ventures.

CONCLUSION AND RECOMMENDATION

The regression analysis provides compelling evidence that the determinants of credit risk differ substantially between Islamic and conventional banks in Malaysia. For Islamic banks, three variables emerged as statistically significant: bank size, capitalization, and profitability. Bank size was found to have a significant negative relationship with credit risk, indicating that larger Islamic banks are generally better at managing credit exposures, likely due to diversified loan portfolios and stronger internal controls. This supports prior findings in the literature that associate larger institutional scale with enhanced stability and risk mitigation. Profitability also demonstrated a significant negative association with credit risk, suggesting that higher earnings provide Islamic banks with greater buffers to absorb potential loan losses. This aligns with the principles of Shariah-compliant finance, where banks tend to adopt a more conservative approach in provisioning and income utilization. Interestingly, capitalization in Islamic banks showed a significant positive relationship with credit risk. This counterintuitive finding may suggest that well-capitalized Islamic banks could be inclined to engage in riskier credit activities, potentially reflecting a trade-off between capital adequacy and credit discipline.

In contrast, the results for conventional banks highlight a different set of determinants. Capitalization, financing growth, and liquidity all showed significant associations with credit risk. Capitalization maintained a positive and significant relationship, reaffirming the potential risk-taking behavior enabled by strong capital reserves. Financing growth exhibited a negative and statistically significant relationship with credit risk, implying that measured and controlled loan expansion may reduce risk, possibly due to effective credit screening mechanisms and economies of scale in underwriting. Liquidity also showed a significant positive relationship with credit risk in conventional banks, which may reflect a tendency among these banks to channel excess liquidity into higher-risk lending opportunities, particularly in competitive market environments. Interestingly, neither profitability nor bank size were statistically significant in influencing credit risk among conventional banks. This may suggest that in interest-based financial systems, the protective effects of profitability and scale are less pronounced, and credit risk is more influenced by capital structure and liquidity deployment.

Comparatively, these findings highlight the structural and operational contrasts between Islamic and conventional banks. Islamic banks demonstrate greater sensitivity to internal financial health, as reflected in the significance of profitability and bank size. The adherence to Shariah principles appears to instill more conservative credit risk behavior, with profit-sharing mechanisms and ethical financing policies guiding risk assessment. On the other hand, conventional banks are more affected by macroprudential factors such as capitalization and liquidity, which may reflect their broader market engagement and more flexible financial instruments. These differences not only validate the need for differentiated credit risk models but also emphasize the importance of regulatory policies that reflect the operational logic of each banking system.

Recommendations: Future research should address the limitations identified, such as the potential for more comprehensive data collection and the exploration of different variables affecting credit risk. Additionally, it is recommended that banks, especially in dual banking systems like Malaysia, enhance their loan loss provisioning strategies to mitigate credit risk effectively. This includes adopting internationally recognized accounting standards and improving the management of collateral to safeguard against potential defaults. Moreover, regulatory bodies like Bank Negara Malaysia should continue to oversee and provide guidelines to ensure the stability and health of the banking sector, including conducting stress tests to assess banks’ resilience to adverse economic conditions.
