The financial system is the main source of fulfillment of promises by the state

The financial system is a set of certain financial relations, the links of which can be grouped into three main blocks. Each of these blocks is represented by an internal structure:

- centralized finance, represented by the state budget and credit, off-budget funds, personal and property insurance funds and the stock market;

- Decentralized finance, which includes finances of credit institutions, insurance companies and private pension funds, finances of commercial and non-commercial structures;

- Household finances.

Depending on the methods of using stock funds, a financial system is formed. This is reflected in the social reproduction.

For example, the use of centralized finance is used in regulating the national economy. With their help, resources are mobilized in the budgetary system with subsequent distribution by economic regions, branches of the national economy or individual groups of citizens.

As indicated above, the financial system is also the presence of decentralized finances used in regulating social and economic relations within individual economic entities. It is in this part of this system that a significant part of all the state's monetary resources is formed.

But household finances are personal finances. In other words, these are certain monetary relations between citizens who conduct a common household and live together.

The financial system is an expression of economic relations related to the provision of monetary resources by the private, municipal and public sectors of the economy, as well as spheres of circulation, production and households.

International relations in the economic sphere are an integral part of a very complex sphere of world economy. It is on their effectiveness that a universal financial system is built in which the problems of the national and global economies must be concentrated. In other words, any international relations are simply inconceivable without a well-established system of economic relations.

The world financial system consists of economic relations connected with the use of world money and servicing certain interrelationships between some countries that are expressed in foreign trade, capital export, investment and tourism.

Stable functioning and further development of such a system should be conditioned by productivity growth, the creation of an effective world market and the formation of a global economic system.

Modern economies of many countries are in close interaction. For example, the financial crisis of one country is a threat to the economic stability of others. And defaults, bankruptcies and debt moratoria in a certain country cause a collapse of exchange rates and shares, non-payments and a sharp rise in prices throughout the world.
