AI-powered real-time trade surveillance for one of the world's largest trading floors

A tier-one global investment bank needed to monitor tens of millions of trades across multiple exchanges and asset classes — in real time. BraivIQ designed and deployed an autonomous AI surveillance engine that now flags cross-venue anomalies before they become compliance incidents.

The challenge

Legacy surveillance tooling couldn't keep pace with volume or cross-market complexity. Compliance teams were flying blind on cross-asset patterns, and the bank faced material regulatory exposure on every missed signal. Multi-year incumbent projects had stalled. Senior leadership wanted a working pilot in weeks, not years.

The approach

We ran a two-week discovery sprint with surveillance, ops, and platform engineering. The architecture deliberately separated detection, decision, and audit layers — every action by every agent is fully traceable to the source event, with nanosecond granularity retained for 7+ years to satisfy regulator record-keeping rules.

The solution

Agentic AI agents that continuously monitor trading patterns and detect anomalies across all instruments and venues in real time.
AI automation layer handling decision logic, escalation paths, and reporting that previously required entire compliance teams.
Nanosecond-granularity event store with zero-latency replay for any post-hoc investigation.
Unified surveillance dashboard giving front office and compliance a single shared view of market behaviour.
Full audit log of every model call, prompt, tool use, and decision — wired into the bank's existing SIEM.

The results

Routine compliance workload: ↓ 70%+ — Surveillance team freed for high-judgement decisions.
Anomaly detection: Real-time — Across all instruments and venues, end-to-end.
Pilot to production: 11 weeks — Replacing a stalled multi-year incumbent project.
Cross-venue blind spots: 0 — Six months post-launch.

"BraivIQ replaced years of stalled work with a working system in weeks. The cross-venue visibility is something our previous vendor could never deliver." — Head of Surveillance, global investment bank, London
