One of the key trends in the financial market, which actively manifested itself during the pandemic and then under sanctions pressure, was the active development of collective investments. At the same time, the new operating conditions for management companies, associated with the blocking of foreign assets, provoked significant difficulties in providing financial services to clients. In the current conditions, there is an increasing need to assess the practice of functioning of mutual investment funds and create mechanisms to reduce the negative consequences of the sanctions burden for individual financial market entities. Based on an analysis of the operating conditions of the management company and an assessment of the efficiency of managing the funds of mutual investment funds, it was determined that the key problems in the activities of the management company are the lack of significant financial results in the management of mutual funds, as well as the suspension of the work of five funds, which resulted in a deterioration in the financial performance of the company. In particular, there was a reduction in the company's assets by a third, an increase in country and currency risks, as well as a significant increase (by 350%) in labor costs. Based on the results of the analysis, the authors formulated measures to improve the efficiency of the company, including the creation of a personnel policy management system to improve the efficiency of the fund, the implementation of a scheme for the settlement of frozen assets by transferring funds from frozen mutual funds to a closed fund, as well as the transition to passive strategies for managing mutual funds. A project for a fund focused on Islamic investments has been developed, the portfolio of which includes shares of companies included in the Moscow Exchange Islamic Investment Index. An assessment of the fund’s potential showed prospects for forming the value of the fund's net assets in the amount of 990 million rubles.
