The agency theory is the starting point in this work to incorporate the achievements of leadership and related theory of power into the economic enterprise theory, in particular regarding credit institutions.  Research aims. The goal is to propose a model of leadership based on values and institutions and to link it with the agency theory, creating a broader perspective on the perception of reality of credit institutions in the light of the modern management concepts. Methodology. The non‑parametric Data Envelopment Analysis (DEA) method was used to assess the effectiveness of leadership in credit institutions, which helped to identify the most effective units among banks providing intermediary services in Poland. The analysis was carried out with focus on effects. Key findings. Powszechna Kasa Oszczędności Bank Polski was assessed as the best in terms of incurred inputs to the achieved effects. Relatively low effects at high inputs were, in turn, achieved by Bank BGŻ BNP Paribas and Plus Bank. Significant differences are noted when comparing the banks’ performance in relation to the averages (the entire sector and the most important competitors).
