Over time several economists of the world have tried to find a model that would determine the security of commercial banks as well as stability of the commercial bank system and would help forecast potential problems in commercial banks and prevent their insolvency. Nowadays the development of the commercial bank assessment is topical and important not just for the potential customer and credit institutions themselves that are interested in early detection of likely problems and adequate assessment of bank contractors, but also for the supervisory institutions. Over recent 10 years the world has achieved a significant progress in strengthening the commercial bank stability and in decreasing the likelihood of crises and their consequences. This has been ensured by work of both national central banks and supervisory institutions as well as international organizations – the World Bank and IMF on developing new methods for the bank stability assessment, including rating systems, stress testing and macroprudential indicators. Nowadays the development of the commercial bank assessment system is topical and important not just for the potential customers and credit institutions themselves interested in early detection of the possible problems and adequate assessment of the contractor banks, but also for the supervision institutions as they will provide for the possibility to forecast the likely problems in commercial banks and prevent the insolvency of commercial banks.
