The UK Financial Conduct Authority's Mills Review has issued a stark warning: the rise of autonomous "agentic AI" — artificial intelligence systems capable of making continuous, delegated financial decisions without human-in-the-loop supervision — will fundamentally break legacy financial infrastructure. The review argues that settlement rails designed for human-paced, episodic transactions cannot support the speed, volume, and automation requirements of AI-driven finance.
The Agentic Finance Thesis
The FCA's report reframes the question of financial market structure. Traditional retail finance assumes a human making periodic decisions — logging in to transfer funds, authorize a trade, select an insurance product. The Mills Review argues that AI agents operating on behalf of consumers will instead make continuous, micro-level decisions at machine speed, requiring infrastructure capable of instant atomic settlement rather than batch clearing cycles that run on T+1 or T+2 timelines.
The review identifies three infrastructure requirements for agentic finance:
- Programmable settlement infrastructure: Smart contracts or equivalent programmable rails that execute conditional payments without manual confirmation.
- Systemic stablecoins: Digital cash that settles instantly and holds value across AI agent operations, replacing the friction of fiat conversion in automated workflows.
- Tokenized assets: Securities and instruments represented onchain so AI agents can transact directly without custody intermediaries introducing latency.
Regulatory Recommendations
The Mills Review stops short of mandating specific infrastructure choices, but makes clear that the FCA views tokenization and programmable money as foundational to a functioning agentic financial system. Its specific recommendations include:
- Scaling the FCA AI Lab to develop sandboxed testing environments for agentic financial applications
- Establishing governance and accountability frameworks for AI agents acting with financial delegation authority
- Working with HM Treasury on systemic stablecoin designation criteria, acknowledging that "e-money token" frameworks may be insufficient for stablecoins operating as the settlement layer for AI agent activity
Implications for XRPL and DLT Infrastructure
The FCA's analysis is directly relevant to XRPL-based infrastructure. The XRP Ledger's design — fast finality (3-5 seconds), low transaction cost ($0.0002), native DEX, and programmable escrow — aligns with the requirements the Mills Review identifies for agentic finance. RLUSD as a MiCA-compliant, FCA-registered stablecoin is positioned as the kind of "systemic stablecoin" the review describes.
The broader regulatory signal is significant: a G7 financial regulator has formally acknowledged that AI-driven finance is not a speculative future scenario but a near-term structural reality requiring proactive infrastructure decisions. For builders working on tokenized asset infrastructure and programmable payment rails, the FCA's endorsement of the underlying requirements represents meaningful policy tailwind.
