AI Agents Now Move Real Capital in Finance, but Audit Trails Haven't Kept Up

A Reddit post argues that within a year, AI agents in finance went from hypothetical to autonomously executing trades, managing treasury, reconciling invoices, and making credit decisions at enterprise scale—while the infrastructure to prove what they did hasn't moved.

Key distinction: logs are not audit trails. Logs capture what the system chose to record; an audit trail proves every step was authorized, nothing was omitted, and the record exists independently of whoever ran the agent. The failure mode is quiet—an agent completes the task, output passes review, then months later the trail collapses under scrutiny.

Teams solving this treat execution records as infrastructure: each action tied to its authorization at the moment it happens, with records stored independently (the author mentions on-chain approaches already running at institutional scale).
