Under the current system, the central bank allows direct access to its accounts only to a limited number of entities such as private banks. From the viewpoint of the usage of information, the central bank leaves the private sector the opportunities to utilize detailed data such as "who buys what" attached to daily transactions.
At the same time, the central bank can obtain the information necessary to maintain the stability of payment and settlement systems through operating its wholesale settlement systems. The issuance of central bank digital currencies could also affect such a role-sharing structure for utilizing information.
