Impact of Diversification, Political Stability & Regulatory Quality on Financial Performance: Empirical Evidence from Banking Sector of Pakistan

Abstract

This study investigates the impact of income diversification, political stability, and regulatory quality on the financial performance of banks in Pakistan. The research evaluates how these factors influence key financial metrics such as Return on Assets (ROA), Return on Equity (ROE), and Net Interest Margin (NIM). The study employs a dynamic panel data model using financial and macroeconomic data from 33 scheduled banks in Pakistan for the period 2007–2021. The data is analyzed using the Generalized Method of Moments (GMM) to address endogeneity and ensure robust findings. The results reveal that income diversification positively impacts both ROA and ROE, indicating that banks with diversified revenue streams are more efficient and resilient to economic shocks. Political stability was found to significantly enhance financial performance by reducing operational risks and fostering a conducive environment for growth. Regulatory quality also showed a positive relationship with ROA and ROE, highlighting its role in strengthening governance frameworks and operational efficiency. However, over-diversification and weak regulatory enforcement were observed to introduce risks, particularly during economic downturns. Encouraging balanced income diversification strategies can stabilize revenues and mitigate risk. It provides valuable insights for developing market-specific strategies to enhance financial stability and profitability.
