In brief

  • The initiative includes verifying an AI agent’s identity and delegated authority.
  • Potential use cases include everyday payments, treasury management and machine-to-machine services.

What changed

Hong Kong’s monetary authority launched Project SAGE on 2 November to explore agentic finance with an expert group. Its programme includes identity checks for AI agents, authentication and the authority users delegate to them. Other work covers interoperability and questions of liability and consumer protection. Proposed applications span everyday purchases, business procurement, treasury management and payments between machines for digital services.

Why it matters

The useful question is how a service knows that software is acting within someone’s permission. Faster execution alone cannot answer who approved a payment or which limits apply. SAGE creates a forum for exploring those requirements; it is not a public payment product or blanket approval for autonomous spending. For digital-money readers, it highlights identity and authorization as infrastructure needed alongside programmable payment tools.
