Development of the regulation of bank capital is analysed. The original microprudential approach is mentioned that involved macroeconomic impacts from its introduction. Based on the analysis of capital structure as conceived from Basel I to Basel III approaches of regulation to this important indicator are discussed. Instability sources and indicative instruments of macroprudential policy are analysed on an example of the excessive growth of credits and leverage as an instability source and countercyclical capital buffer, sectoral capital requirements and leverage ratio in the role of indicative instruments.
