The function and value of commercial banks in fostering capital market growth

This paper explores the critical role that commercial banks play in the development and deepening of capitalmarkets, particularly in both emerging and developed economies. Capital markets are essential mechanisms for mobilizinglong-term funds, fostering investment, and supporting sustainable economic growth. While traditionally perceivedas institutions focused on deposit-taking and lending, commercial banks have increasingly expanded their functionsto include underwriting of securities, management of investment portfolios, and facilitation of financial intermediationbetween investors and issuers.By utilizing a mixed-method approach that includes empirical data analysis, cross-country comparisons, and trendevaluations from 2015 to 2022, this study reveals a robust positive correlation between the scale and efficiency ofthe banking sector and key indicators of capital market development. These indicators include market capitalization,the number of initial public offerings (IPOs), and the issuance of corporate bonds. Countries with well-capitalized anddiversified banking systems demonstrate stronger capital market activity, higher investor confidence, and more stableaccess to financing for the private sector.Furthermore, the study identifies how policy frameworks, technological innovations, and institutional capacities ofcommercial banks influence their effectiveness in supporting capital markets. The findings provide important implicationsfor financial regulators, policymakers, and development strategists who seek to strengthen financial ecosystems bypromoting closer integration between banking institutions and capital market infrastructure
