Abstract
Commercial banks play a critical role in economic
development by mobilizing savings, facilitating payments, extending credit to
businesses and households, and contributing to financial stability. The profitability of commercial banks is a critical
indicator of their financial health and sustainability, which in turn impacts
the overall stability and growth of the regional economy as well as the national
economy. Thus, this article discusses the key internal and external factors
affecting the profitability of commercial banks and is anchored with different
economic theories, which include Agency Theory, Risk Management Theory, Structure–Conduct–Performance
(SCP) Theory, Trade-off Theory, and Macroeconomic Theory.

Introduction
A commercial bank is a financial
institution that accepts deposits, provides loans for individuals and
businesses, and offers other services like checking accounts, certificates of
deposit, and foreign exchange services. In
the Philippines, banking continues to be fundamental for growth, especially in
provinces where financial inclusion, investment, and local business development
hinge on access to banking services. Ilocos Norte, as a growing province in
Region I, has seen increasing economic activity and investment, contributing
significantly to the Gross Regional Domestic Product.
However, profitability remains a continuing concern in
the banking sector, influenced by both internal (bank‐specific) and external
(macroeconomic, regulatory, market) factors. Most importantly that there are several changes occurring in the Philippine banking sector, because of its
adaptation to new conditions such as the deregulation of the national markets and
the level of competitiveness internationally. At the national level, the Bangko
Sentral ng Pilipinas is actively pushing for reforms to accelerate the
development of the domestic capital market as an alternative funding source for
the economy. Since it is reported that about 98% of the local companies in the
Philippines are supplied by the banks, while 2% comes from the capital market.
This reform may have capital implications on banking profitability due to
increasing market competition. Understanding
the factors that affect the profitability of these banks is essential not only
for bank management but also for policymakers, investors, and stakeholders who
seek to enhance the banking sector’s performance and contribution to economic
development (Hinlo, 2025).
Profitability
of Commercial Banks
This article focuses on analysing
key internal and external factors affecting the profitability of commercial
banks. Internal factors typically include bank-specific determinants such as
bank size, capital adequacy, asset quality, operational efficiency, loan
portfolio composition, and liquidity management. External or macroeconomic
factors encompass economic growth, inflation rate, money supply, government
regulations, and competitive pressures within the banking industry.
Prior studies in the Philippine
banking context have shown that bank efficiency, money supply growth, bank
size, and liquidity significantly affect banking profitability, while other
studies in similar developing regions highlight the importance of capital
adequacy and asset quality as primary profitability drivers. And these are
being anchored with different theories.
Agency Theory
explores the relationship between principals (e.g., shareholders or
owners) and agents
(e.g., managers or bank officers), where the agents are supposed to act in
the best interest of the principals leading to information asymmetry and
potential inefficiencies, impacting profitability through increased monitoring
costs, risk-taking (moral hazard), and suboptimal decisions, mitigated by
strong governance, incentives, and regulation to align actions with shareholder
wealth. (Sukendri
et al., 2024)
Meanwhile, risk management theory in
banking posits that effectively identifying, assessing, and mitigating
risks (credit, liquidity, market, operational) is crucial for sustainable
profitability, as these risks directly impact performance, while also influencing
risk-taking behavior, creating a complex interplay where good management can
boost returns but excessive profitability might paradoxfully encourage riskier
ventures, aiming to balance growth with stability. (Babulo & Viswanadham, 2021)
On the other hand, the Structure–Conduct–Performance (SCP)
framework is used to examine how the market structure of commercial banks and their
operational conduct affect financial performance. Through this model, the study
identifies both structural (e.g., competition, market size) and conduct-related
(e.g., pricing, credit policy) determinants of profitability.
Moreover, Trade-Off
Theory serves as a theoretical foundation for examining how capital structure
decisions affect bank profitability. According to the theory, banks must
balance the benefits of leverage (e.g., tax shields, increased lending
capacity) against the potential costs of financial distress and regulatory
non-compliance. In the context of commercial banks in Ilocos Norte,
understanding this balance can help explain variations in profitability across
institutions with different capital adequacy levels.
This study is also grounded in macroeconomic theories,
which explain how large-scale economic factors affect firm-level performance.
According to Keynesian and monetarist perspectives, variables such as GDP
growth, inflation, interest rates, and unemployment significantly influence the
behaviour of borrowers and the operational environment of banks. In the context
of Ilocos Norte, where local economic conditions are closely tied to
agricultural production, tourism, and remittances, these macroeconomic forces
are expected to have a direct impact on bank profitability.
Factors
affecting profitability
The profitability of commercial banks is shaped by a complex
interaction of internal (bank-specific) and external (environmental) factors,
and these relationships can be clearly explained through established financial
and economic theories.
From an internal perspective, factors such as management
efficiency, asset quality, capital adequacy, liquidity management, cost
control, and risk-taking behaviour play a decisive role in determining bank
profitability. Agency Theory highlights how conflicts between
shareholders, managers, and depositors can reduce profitability when managerial
decisions prioritize personal interests over value maximization. Strong
corporate governance, performance-based incentives, and effective monitoring
mechanisms help mitigate agency costs and improve profitability. In line with Risk Management Theory,
prudent credit risk, market risk, and operational risk management enhance
profitability by reducing non-performing loans, stabilizing earnings, and
preserving capital. Banks that balance risk and return effectively tend to
achieve more sustainable profits.
Capital structure decisions are also critical. Trade-off Theory
explains that banks aim to optimize their capital mix by balancing the tax
benefits of debt against the costs of financial distress. Adequate
capitalization strengthens confidence, reduces funding costs, and enhances
resilience, thereby positively influencing profitability, although excessive
capital may dilute returns.
From an external perspective, market structure, competition, and macroeconomic conditions significantly influence bank performance. The Structure–Conduct–Performance (SCP) Theory suggests that banks operating in more concentrated markets can exercise market power, set favourable pricing for loans and deposits, and earn higher profits. However, excessive concentration may reduce efficiency and innovation over time. Meanwhile, Macroeconomic Theory emphasizes that economic growth, inflation, interest rates, and monetary policy directly affect banks’ profitability by influencing credit demand, loan quality, and net interest margins. Favourable macroeconomic conditions generally support higher profitability, while economic downturns increase credit risk and compress margins.
Conclusion
Overall, commercial bank profitability is not determined by a single
factor or theory but by the dynamic interaction between internal managerial
decisions and external economic and market forces. Banks that align effective
governance (Agency Theory), sound risk practices (Risk Management Theory),
optimal capital structures (Trade-off Theory), competitive strategies (SCP
Theory), and adaptability to macroeconomic conditions (Macroeconomic Theory)
are better positioned to achieve sustainable and resilient profitability.
