These are: (a) Trust in government and central bank offering the CBDC, (b) expressed guarantees for those using it, (c) the favourable reputation of other active CBDCs, (d) the CBDC technology, the automation and limited human involvement necessary, (e) the trust building features of the retail bank’s CBDC wallet app, and (f) the privacy features of the retail bank’s CBDC wallet app and back-end processes.

Abstract

Central bank digital currencies (CBDC) have been implemented by some countries and trialled by many more. The consumer has an increasing range of financial services to choose from including decentralised blockchain-based cryptocurrencies. A CBDC may use blockchain technology, but it is centralized, so the institutions that support it play an important role. Despite the centralised top-down nature of this financial technology, it still needs to be adopted so the consumer’s perspective, particularly their trust in it, is very important. Each CBDC implementation can be different, and each country’s context can be different, therefore it is important to understand each case separately. This research models the Brazilian consumer’s trust in their two-tier CBDC, where the central bank and the retail banks retain their current role. The six ways to build trust in a CBDC, identified by previous research in a different region, are supported for this case also. These are: (a) Trust in government and central bank offering the CBDC, (b) expressed guarantees for those using it, (c) the favourable reputation of other active CBDCs, (d) the CBDC technology, the automation and limited human involvement necessary, (e) the trust building features of the retail bank’s CBDC wallet app, and (f) the privacy features of the retail bank’s CBDC wallet app and back-end processes.
