Banking stability is a fundamental pillar of the financial system; however, empirical evidence on the impact of bank diversification on stability remains inconclusive. This study aims to examine the effects of income diversification, asset diversification, and loan diversification on banking stability, with intellectual capital serving as a moderating variable. The study employs panel data from 42 commercial banks listed on the Indonesia Stock Exchange (IDX) over the period 2019–2023 and applies panel data regression using a fixed effects approach. The results indicate that income diversification has a negative and significant effect on non-performing loans (NPLs), with a coefficient of ?1.680 (p < 0.01), indicating an improvement in banking stability. In contrast, loan diversification has a positive and significant effect on NPLs, with a coefficient of 7.087 (p < 0.01), thereby weakening banking stability. Meanwhile, asset diversification does not exhibit a significant direct effect on NPLs. The key finding of this study lies in the role of intellectual capital, measured using the Value Added Intellectual Coefficient (VAIC), which significantly moderates the relationship between asset diversification and banking stability, with an interaction coefficient of ?2.995 (p < 0.01). However, intellectual capital does not moderate the relationships between income diversification or loan diversification and banking stability. Overall, the findings underscore that the effectiveness of bank diversification strategies critically depends on the quality of intellectual capital management, particularly in addressing the complexity of asset portfolio diversification. These findings provide important implications for bank management and policymakers in designing sustainable diversification strategies to maintain financial system stability.
