Russia’s entry into the top five economies of the world depends, among other things, on the development of the financial sector, being a necessary condition for the economic growth of a developed macroeconomic and macro-financial system. The financial sector represents a system of relationships for the effective collection and distribution of economic resources, their deployment according to public demand, reducing the risk of overproduction and overheating of the economy.Therefore,the subject of the researchis the financial sector of the Russian economy.The purpose of the researchwas to formulate an approach to alleviating the risks of increasing financial costs in the real sector of the economy by reducing the impact of endogenous risks expressed as financial asset “bubbles” using the experience of developed countries in the monetary policy.The paper analyzes a macroeconomic model applied to the financial sector. It is established that the economic growth is determined by the growth and, more important, the qualitative development of the financial sector, which leads to two phenomena: overproduction in the real sector and an increase in asset prices in the financial sector, with a debt load in both the real and financial sectors. This results in decreasing the interest rate of the mega-regulator to near-zero values. In this case, since the mechanisms of the conventional monetary policy do not work, the unconventional monetary policy is used when the mega-regulator buys out derivative financial instruments from systemically important institutions. As a conclusion, given deflationally low rates, it is proposed that the megaregulator should issue its own derivative financial instruments and place them in the financial market.
