5-bank asset concentration

This metric assesses the proportion of total assets held by the five largest banks within the Bankscope database, providing critical insights into the degree of market concentration and potential systemic risk in the banking sector. Calculated by taking the sum of assets from the top five banks and dividing this figure by the total assets of all banks listed in Bankscope for the year 2025, the measure ensures relevance by being reported only when at least five banks are present. Utilized effectively, this indicator can highlight shifts in competitive dynamics, inform policymakers about concentration risks, and aid analysts in evaluating the resilience of the banking ecosystem under various economic conditions.
