The main object of the author in this work is to point out the importance of the life insurance companies as the institutional investors as well as their importance in financing of national economy. The majority of functions that life insurance companies have prove their importance on the market, not only in national but also in global terms. Huge financial power of these financial institutions can be seen in their dominant position in gross national savings and the possibilities to provide a new and cheaper way of financing a country, industry and everything else that needs its help. That is the way they raise industry growth rate, influence the economic development, increase GDP, decrease the unemployment and provide macroeconomic stability.
