Key insights

1. Tokenized reserves are direct central bank liabilities issued on distributed ledger technology and restricted to eligible financial institutions.p.8
2. Central banks explore tokenized reserves primarily to preserve central bank money as a risk-free settlement asset and to improve wholesale payment efficiency.p.9
3. Strict atomic settlement requires money and assets to reside on the same ledger environment to guarantee simultaneously executed transactions.p.11
4. Implementing tokenized reserves on permissionless DLT presents critical governance challenges regarding system management and control.p.12
5. Central banks must maintain exclusive control over core functions, including token issuance, redemption, access policy, and emergency settlement halts.p.17
6. Tokenization does not fundamentally alter a central bank's ability to implement monetary policy, but it enables automated liquidity management via smart contracts.p.20
7. The temporary coexistence of traditional and tokenized reserves can cause liquidity fragmentation across separate reserve pools.p.23
8. Real-time gross settlement links enable delivery-versus-payment settlement in central bank money without requiring single-ledger tokenized reserves.p.25
9. Central banks should align their strategic posture with market readiness, institutional capacity, and legal preparedness.p.30
