Retail CBDC presents opportunities but raises concerns about privacy and control in digital payments.
Abstract
Nations are exploring retail CBDC as a digital form of money alongside cash and reserves.
Motivation stems from declining use of central bank money for retail purchases.

Privacy is a key concern with proposals suggesting limitations that may impact consumer rights.
Custody models differ with some proposals favoring intermediaries over direct possession by users.
Role of identity in transactions varies between balances and tokens with implications for privacy and control.
