AI Governance for Investment Banking & Capital Markets

Investment banks operate under some of the strictest regulatory regimes in the world. AI assistants used by traders, research analysts, and deal teams must never leak Material Non-Public Information (MNPI), must maintain full audit trails for MiFID II and SEC examinations, and must stay within tight cost budgets on high-frequency trading floors. Keeptrusts lets you enforce all of these requirements in a single policy configuration deployed at the gateway layer.

Use this page when

You are deploying AI for trading desks, research analysts, or deal teams where MNPI controls and Chinese wall enforcement are mandatory.
You need MiFID II-compliant audit trails, SEC examination readiness, and real-time AI spend controls per desk or trader.
You want to enforce information barriers between deal-side and research-side AI assistants at the gateway layer.

AI Challenges in Investment Banking

Challenge	Risk	Regulatory Exposure
MNPI leakage through AI prompts	Insider trading liability	SEC Rule 10b-5, MAR
Market manipulation signals in AI output	Regulatory sanctions	MiFID II, Dodd-Frank
Uncontrolled AI spend on trading desks	Budget overruns	Internal risk controls
Missing audit trails for AI-assisted decisions	Examination failure	SEC, FCA, BaFin
Cross-wall information flow	Chinese wall breach	MiFID II organizational requirements

How Keeptrusts Helps

MNPI Filtering & Chinese Wall Enforcement

The mnpi-filter policy inspects every prompt and response for references to pre-release earnings, pending M&A activity, and other material non-public information. Combined with rbac, you can enforce Chinese wall segmentation so that deal-side AI assistants never access research-side data.

MiFID II Audit Trail

Every AI interaction flows through the gateway and is recorded as a decision event. The control-plane API stores full request/response pairs, policy decisions, and timestamps — exactly what examiners ask for.

Real-Time Spend Controls

The Cost Center and Wallets in the Console let you set per-desk, per-trader, or per-team budgets. When a trading desk hits its allocation, the gateway blocks further requests until the budget is replenished.
