While the Colombian central bank is still deliberating the potential issuance of a central bank digital currency (CBDC), it is considering the implementation of transaction restrictions on a CBDC, recognizing the benefits it could bring. In its recent study titled "Expected Mac economic impacts of Issuing a Retail CBDC," the Bank of the Republic of Colombia concluded that introducing a retail CBDC would not impose significant macroeconomic risks.
In order to mitigate possible threats tied to CBDCs, the Colombian central bank has suggested the adoption of limits on both the holding and spending of the digital currency. This approach, the bank contends, would enhance fund security, safeguarding users against cyberattacks targeting their balances or transactions.
The proposal for restrictions on retail CBDC holdings presents an opportunity for regulators to navigate the delicate balance between privacy and transparency. The central bank could provide digital wallets with varying holding limits and levels of privacy, enabling users to tailor their preferences. Some individuals may opt for wallets with lower holding limits but higher privacy, while those more comfortable sharing data might choose higher limits and lower privacy levels.
Furthermore, the central bank noted that CBDC restrictions could serve the interests of commercial banks. By diminishing the competitive edge of retail CBDC as a store of value compared to traditional bank accounts, any potential negative impact on bank operations could be alleviated. Additionally, these Restrictions might influence the appeal of other cash-like instruments, such as government bonds, commercial paper, term deposits, and certificates of deposits.
Despite its ongoing monitoring of global CBDC developments, the Colombian central bank remains undecided about the necessity of a digital currency in the country. The bank acknowledges that the decision to issue a retail CBDC should factor in the currency's features and desire city, aiming to cultivate a core user base and the necessary network effects for sustainability.
This consideration for transaction limits aligns with a trend seen in other jurisdictions. In the UK, financial and trade bodies like UK Finance have proposed caps on digital pound holdings to prevent destabilization of the traditional banking system. Similarly, in 2020, Ulrich Bindseil of the European Central Bank suggested a cap of 3,000 euros per person for digital euro holdings.
