GRU monetary operations
Day-to-day operations cover primary issuance, secondary market support where mandated, and collateral management. Operational control links treasury approvals, regulated counterparty execution, ISO 20022 payment references, OMNL journal entries, HYBX workflow state, and Chain 138 settlement evidence.
Four-control operating doctrine
- Treasury Control — mandates, signatories, internal approvals, reserve policy, and appointment authority.
- Compliance Control — enhanced due diligence, KYC/CDD, sanctions screening, source-of-funds review, and ongoing monitoring.
- Settlement Control — ISO 20022 payment spine, bank acknowledgements, OMNL journal entries, and HYBX workflow state.
- Evidence Control — reconciliation packets, message references, payload hashes, and optional Chain 138 attestation.
