Researchers at the Bank of Korea (BoK) have published a study that looks into effects of central bank digital currency (CBDC) issuance on financial stability.
The study examined the implications of CBDC for financial stability using a model in which commercial bank deposits compete with the central bank deposits in CBDC account and public could access CBDC via direct deposit at the central bank.
According to the report, introducing deposits in CBDC account would decrease the supply of private credit by commercial banks. This, in turn, would raise nominal interest rate, thereby lowering a commercial bank's reserve-deposit ratio.
“This has negative effects on financial stability by increasing the likelihood of bank panic in which commercial banks are short of cash reserves to pay out to depositors,” it said.
“However, once the central bank can lend all the deposits in CBDC account to commercial banks, an increase in the quantity of CBDC which does not require reserve holdings can enhance financial stability by essentially increasing supply of private credit and hence lowering nominal interest rate.”
Last year, Christine Lagarde, the head of the International Monetary Fund (IMF), had said that central banks should start considering issuing digital currencies. Central bank digital currencies or CBDCs could help prevent “too much power [falling] into the hands of a small number of outsized private payment providers,” she said.
Recently, the Bank of Thailand (BOT) completed the first phase of a project focused on domestic wholesale fund transfer using wholesale CBDC. “The results of Project Inthanon Phase I indicated that DLT can fulfil basic payment functionalities,” the BOT said, adding that the technology “demonstrated capabilities to help enhance payment efficiency and to support interbank transfer and settlement during off-hours.”
