The Interrelationship between Financial Systems and Economic Growth: A Comprehensive Analysis

Abstract

The relationship between financial systems and economic growth has remained a central theme in economic research and policy discourse. This study provides a comprehensive analysis of the interrelationship between financial systems and economic growth by synthesizing theoretical and empirical evidence from 50 peer-reviewed studies spanning developed, emerging, and developing economies. Using a systematic qualitative methodology, the research examines how financial institutions, markets, and regulatory frameworks influence growth outcomes across different institutional and structural contexts. The findings reveal that financial systems play a crucial role in promoting economic growth through improved savings mobilization, efficient capital allocation, risk diversification, and innovation support. However, the effectiveness of financial systems is highly conditional upon institutional quality, governance structures, and regulatory effectiveness. The study further identifies financial system structure and nonlinear dynamics as critical moderating factors, demonstrating that diversified financial systems are more resilient and that excessive financial deepening can hinder growth beyond certain thresholds. Additionally, the analysis highlights the complex role of globalization and financial openness, which can enhance growth when supported by strong institutions but may increase vulnerability in weak regulatory environments. The study concludes that sustainable economic growth depends not on financial expansion alone, but on the quality, stability, and inclusiveness of financial systems. The findings offer valuable policy insights by emphasizing the need for balanced financial development strategies tailored to institutional and economic contexts.
