In calculations banks don't use any money.

In calculations banks don't use any money.  Banks  measure  in currency (any) only the monetary debts, reverse (according to the card) or nonrecourse (on the account).  Calculations are served only by the  operating system of calculations built  between banks, and money (Central Bank debts) generally fulfills a role of a bank reserve and serves consumers.

The Central Bank with the operating system serves an insignificant share of cash flows.  Reverse debts are serviced by a financial settlements center, for example the VISA.  This "Central Bank of Russia" with its own operating system is located abroad.

It is possible to correct  this situation only by an introduction of a new operating system of calculations between banks.  It is necessary to bind by the relations  the issuer of the monetary document to calculations in the main contract to serve the national economy.  And if  this document is attached to a debt of the Central Bank (money), than the Central Bank will be able to have impact on an operating system of calculations.  It is also necessary to consider interest of bank issuer of the monetary document.  This  is achieved by receiving income from the sale of the service in maintaining the custody account of the monetary document.

The operating system has to:

1)   tie the monetary document to the Central Bank`s debt by making this document  the monetary certificate of the property right to a debt of the Central Bank (money).

2)   tie the issuer of the document to production relations, having made the issuer of the document the payer who pays with it  for the contract of delivery of end products in the production market.

3)  replace the financial obligation by depository obligation that brings in the income to the issuer of the paperless monetary certificate. Both the money is safe, and the income from a turnover of the monetary certificate.
