The Economic Capital Model in Bank’s Capital Assessment

With this chapter, the authors reveal the content of the concept of economic capital, explore approaches to its evaluation, assess the implementation of the concept of economic capital in the national banking system, and identify problems and possible directions for development and convergence of the Russian approach with international requirements. As a result, the need to apply the model of economic capital in assessing bank capital is substantiated. A concept (from Latin “conception” – understanding a system) is a specific way of understanding (interpreting) an object, phenomenon, or process; that is, the main point of view on the subject and the guiding idea for its systematic coverage. This term is also used to refer to a leading idea and a constructive principle in scientific activity. Initially, since 1988, under prudential supervision – a direct, quantitative-oriented approach, there existed a concept of regulatory capital, reflected in the document “International Convergence of Measurement Methods and Capital Standards” (Basel I). Regulatory capital was calculated to meet regulatory oversight standards. It was intended to cover unforeseen losses and reserves already identified; thereafter, expected losses were created. The concept of regulatory capital proceeds from the premise that if capital must cover unexpected losses, it should be borne in mind that a surprise approximates uncertainty. Consequently, the theoretical possibility of occurrence of certain events is excluded and, hence, the methodical and practical ground of the concept of economic capital disappears, which is based on the assessment of default probability and the magnitude of its negative consequences for creditors. The change in trends in banking regulation (the actions of supervisory authorities in matters of capital adequacy acquired a risk-oriented nature that takes into account the risks assumed by each bank and the quality of their management) led to the emergence of the concept of economic capital in 2004, which is reflected in the document “International Convergence of Capital Measurement and Standards of Capital: New Approaches” (Basel II). According to this concept, commercial banks must have sufficient capital to cover not only credit and market, but also the operational risks. Thus, economic capital takes into account all the risky circumstances that a banking institution may encounter. The need to apply the method of economic capital in assessing the capital of a bank is justified and significant.
