Abstract

This study investigates the relationship between Environmental, Social, and Governance (ESG) performance and financial outcomes among commercial banks in Uzbekistan, a rapidly transforming emerging market economy. Using a novel dataset covering 118 bank-year observations from 2018 to 2023, we construct pillar-level ESG scores (E, S, G) and a composite ESG index based on 22 measurable indicators aligned with the Global Reporting Initiative (GRI) Financial Services Supplement and the UN Principles for Responsible Banking (UNPRB). Indicators are normalized using the min–max method and aggregated with equal weighting, reflecting transparency and comparability in a data-constrained context. Financial performance is assessed using accounting-based measures—Return on Assets (ROA), Return on Equity (ROE), and Net Interest Margin (NIM)—alongside efficiency (Cost-to-Income Ratio, CIR) and risk (Non-Performing Loan Ratio, NPL). Control variables include bank size, capital adequacy ratio, liquidity, and ownership type.

The analysis begins with Pearson correlation tests, which reveal three important insights. First, the three ESG pillars demonstrate strong internal consistency, indicating that Uzbek banks tend to adopt ESG practices in an integrated manner rather than selectively. Second, ESG scores exhibit significant positive correlations with profitability measures (ROA and ROE), with governance emerging as the most influential driver. Third, ESG scores are negatively correlated with CIR and NPL, suggesting that stronger ESG practices are associated with greater operational efficiency and lower credit risk. While Net Interest Margin shows a weaker positive association, the overall pattern aligns with global evidence that ESG contributes to both financial resilience and sustainable growth.

Panel regression analysis, supported by the Hausman specification test, further validates these findings. Fixed-effects models controlling for bank-specific heterogeneity and macroeconomic shocks show that ESG scores exert a statistically significant and economically meaningful impact on financial performance. Specifically, higher ESG scores increase ROA and ROE, modestly enhance NIM, and substantially reduce CIR and NPL. Governance once again stands out as the most consistent predictor of improved outcomes, reflecting the importance of board independence, disclosure practices, and risk oversight in the Uzbek banking context.

The results carry important policy and practical implications. For regulators, the findings highlight the need to institutionalize ESG disclosure, integrate sustainability considerations into credit risk assessments, and design incentives that encourage adoption across all banks. For practitioners, ESG should be reframed not as a compliance burden but as a strategic driver of profitability, efficiency, and long-term competitiveness. For researchers, this study opens avenues for further work on the causal mechanisms linking ESG to financial performance, cross-country comparisons in Central Asia, and long-term evaluations of ESG’s impact. By demonstrating that ESG integration yields tangible financial benefits in an emerging market, this study contributes to the global discourse on sustainable finance. It provides empirical evidence that linking sustainability to profitability is not only feasible but also desirable for banks in Uzbekistan, offering a roadmap for aligning financial sector transformation with national development objectives.
