Global Payment Interoperability Protocol (GPIP): A Universal Settlement Layer for CBDCs, Stablecoins, and Traditional Systems
Description
Establish a Global Payment Interoperability Protocol (GPIP) — an open-source, ISO 20022-standard settlement layer that enables any CBDC, stablecoin, or legacy payment system to send and receive value across borders with atomic (instantaneous) settlement and unified compliance.
Three core components: (1) Interledger Standard for CBDCs: All CBDCs must implement a common settlement protocol enabling direct bank-to-bank transfers between different national CBDCs without correspondent banks. Modeled on ILP (Interledger Protocol) but with regulatory hooks for AML/KYC.
(2) Unified Compliance Layer: A shared KYC registry and transaction screening service operated by a neutral multilateral body — eliminates need for each bilateral corridor to negotiate compliance separately.
(3) Universal Liquidity Pools: Central banks establish 24/7 automated liquidity facilities for GPIP-compliant corridors, eliminating the correspondent bank risk premium that adds 3-6% to cross-border costs. The IMF Special Drawing Right (SDR) basket can be the denominator for liquidity pricing.
Implementation Pathway
Phase 1 (2026–2027)
- • GPIP technical standard finalized and adopted by 20 central banks
- • Pilot CBDCs in G20 nations implement GPIP interoperability
- • Unified KYC registry operational for pilot corridor (Singapore-Thailand-Vietnam)
Phase 2 (2027–2030)
- • GPIP adoption by 50+ central banks covering 85% of global GDP
- • Correspondent banking for GPIP corridors reduced by 40%
- • First stablecoin/CBDC bridge corridor live (USDC to eNaira to e-Peso)
Phase 3 (2030+)
- • Universal settlement at sub-second latency across all GPIP corridors
- • Cross-border payment cost reduced below 0.5%
- • Traditional SWIFT corridors decline to legacy use cases only
