The Short Version
The claim captures a genuine concern — many credible institutions warn that CBDCs could concentrate transaction data and enable surveillance. However, the claim's framing as an inevitable outcome ("will result in") is not supported by the evidence. The most authoritative sources (European Data Protection Supervisor, Bank for International Settlements, Homeland Security) consistently describe privacy risks as dependent on design choices, not guaranteed. Privacy-preserving CBDC architectures exist and are actively researched. The accurate statement is that CBDCs *could* significantly reduce privacy if designed without adequate safeguards.
