<p>The subject of the research is the indicators for assessing the level of monopolization of fi nancial markets in Uzbekistan. The purpose of the study is to determine the types of indicators for assessing the level of monopolization of fi nancial markets, acceptable for use in Uzbekistan, and substantiation of their critical values. The methodological basis was provided by fundamental research in the fi eld of competition development and antitrust regulation of fi nancial markets. Structural, logical and systematic approaches were used. The analysis of indicators used in foreign practice for assessing the level of monopolization is carried out; generally accepted and specifi c for individual countries indicators for assessing the level of monopolization of markets and their critical values are determined. The relationship between individual indicators for assessing the level of monopolization is revealed. Based on the analysis of the state of competitive relations in the fi nancial markets, it was found that the credit market is monopolized by banks with state participation, and the stock market is highly concentrated by a small number of participants <br /> due to its underdevelopment. The factors that complicate the quantitative assessment of the state of concentration in the fi nancial markets are identified. The research results can be used by the Antimonopoly Committee of the Republic of Uzbekistan and the antimonopoly authorities of countries with similar economies to form and improve antimonopoly legislation. Inaccordance <br /> with the results obtained, indicators for assessing the level of monopolization of fi nancial markets in Uzbekistan are proposed, the critical values of these indicators are justifi ed.</p>
