Central bank digital currencies can be set up to be secure and private while allowing transactions to be settled on the central bank’s own ledger, the Bank for International Settlements (BIS) has said as it outlines the results of its Project Sela.
Central banks across the world are looking at whether they can issue digital versions of their fiat currency, and Sela in particular is probing how those systems can be protected from hacks and distributed to people.
“If central bank money is to go digital, cybersecurity is key,” Andrew Abir, Deputy Governor of the Bank of Israel, which is examining whether to issue a digital shekel, said in a statement. “The project proved the feasibility of the model we had in mind.”
In project Sela, transactions were settled directly on the central bank’s balance sheet, but BIS said that privacy was preserved because people’s personal identifiers were “obfuscated.”
While many CBDCs, such as the European Union’s proposed digital euro, would use banks and other payment providers to link between central banks and ordinary users, Project Sela uses what it calls a “novel type of intermediary” to handle customer-facing services without the liquidity risk of holding funds directly.

Previous BIS research has indicated 93% of central banks across the world are examining whether to issue CBDCs. That has raised concerns over citizens’ privacy – not least given fears that China will use its digital yuan as a form of social control.

The project’s outcome “will inform our ongoing exploration” of a possible digital Hong Kong dollar, the e-HKD, said Howard Lee, Deputy Chief Executive of the Hong Kong Monetary Authority, which also took part.
