Compliance in Capital Markets Is No Longer a Policy Exercise - It’s a Performance Obligation
Capital markets firms are navigating the most demanding regulatory environment in a generation. Across the EU, the U.S. and beyond, rule-makers aren't just raising the bar on what firms must do; they're fundamentally changing what compliance is expected to look like. The question for C-suite leaders within these firms isn't whether to act, but rather how decisively to act in the face of today’s regulatory landscape.
The Regulatory Landscape Has Shifted Permanently
For years, compliance teams could demonstrate good intent through documented policies, periodic reviews and manual oversight processes. That era is over. Regulators now expect firms to show compliance performance, backed by real-time data, defensible audit trails and evidence of daily surveillance activity.
This shift is visible across every major regulatory framework shaping capital markets today.
EU MAR and MiFID II: The EU's Market Abuse Regulation continues to sharpen expectations around detecting suspicious trades, managing inside information and monitoring for cross-market manipulation. MiFID II reinforces this with stricter requirements for best execution, record-keeping, and surveillance of algorithmic and high-speed trading. Critically, MiFID II has expanded the scope of reportable activity, meaning firms must now capture and analyze a significantly broader range of trading data across multi-asset environments. Compliance will demand organizational access to real-time data and on-demand reporting capabilities.
EMIR 3.0: The latest EMIR reforms introduce active account requirements, compelling firms to maintain clearing accounts at EU central counterparties (CCPs) and to clear a representative portion of certain derivatives domestically. Stronger CCP supervision and enhanced reporting standards raise the bar on data quality, trade reporting accuracy and real-time reconciliation. Firms that haven't yet modernized their reporting infrastructure will feel this acutely.
SEC, FINRA and CFTC: In the U.S., FINRA's 2026 Oversight Report places manipulative trading, Reg BI compliance, best execution and crypto-related activity under intensified scrutiny. Firms must now demonstrate that their surveillance programs detect real-world abusive patterns, not just theoretical ones. The CFTC's growing focus on convergence between securities, crypto and derivatives markets compounds this, requiring firms to monitor across both CFTC-regulated and SEC-regulated products simultaneously.
What This Means Specifically for Capital Markets Firms
The implications for capital markets firms go well beyond updating a few surveillance rules. The regulatory evolution currently underway is driving a structural transformation in how compliance must be architected, governed and evidenced.
Siloed compliance is a liability. Regulators increasingly expect firms to connect dots across trading behavior, payments, communications and third-party data. A suspicious trade may relate to a sanctions issue. A cyber fraud event may surface in both communications monitoring and transaction data. Unified surveillance isn't a best practice anymore; it's the regulatory expectation.
AI governance is now a compliance requirement. As firms deploy AI-driven surveillance tools, regulators expect the same level of auditability from algorithmic decisions as from human-in-the-loop decisioning. Firms must maintain real-time audit trails for both, and governance frameworks must be robust enough to withstand regulatory examination.
Data quality is the foundation of everything. Inaccurate or incomplete data doesn't just create reporting errors; it creates regulatory exposure. EMIR 3.0's enhanced reporting requirements and MiFID II's expanded data capture obligations mean that poor data infrastructure is no longer a back-office problem. It's a boardroom risk.
Modernization: The Key to Staying Ahead
Staying ahead of this regulatory environment requires more than awareness. It demands a structured, organization-wide response.
- Conduct a Cross-Domain Surveillance Audit
Map your current surveillance infrastructure against the full spectrum of regulatory obligations: MAR, MiFID II, FINRA, CFTC and EMIR 3.0. Identify where data silos exist and where cross-domain connections are missing. This audit becomes your baseline for transformation.
Compliance, technology and data teams must collaborate directly, often for the first time at this level of granularity. Breaking down internal silos is both a technical and a cultural challenge. - Build Real-Time Audit Trail Capabilities
Invest in infrastructure that captures and stores evidence of daily surveillance activity, including escalation, review and remediation processes. FINRA's 2026 Oversight Report is explicit: Controls must work in practice, not merely in documentation.
This requires meaningful investment in data engineering and platform modernization, with clear accountability for audit readiness sitting at the senior leadership level. - Establish an AI Governance Framework
If your firm uses AI in surveillance or compliance processes, formalize how those models are validated, monitored and documented. Regulators will expect this as a standard requirement, not an optional enhancement.
Governance frameworks require cross-functional ownership, spanning legal, compliance, technology and risk. Firms that haven't yet established this structure should treat it as a priority. - Upgrade Data Quality & Reporting Infrastructure
EMIR 3.0 and MiFID II both demand higher-quality, more granular data. Firms should assess their current data pipelines, identify gaps in accuracy and completeness and build reconciliation processes capable of operating in real time.
Data quality improvements often require changes to source systems, reporting workflows and vendor relationships, all of which have significant lead times. They say the best time to plant a tree is 20 years ago; the second best time is now. The same holds true of improving your reporting infrastructure. - Move from Compliance Intent to Compliance Performance
This is perhaps the most significant cultural shift required. Boards and executive teams must treat compliance performance as a measurable business outcome, not a background function. Define KPIs for surveillance effectiveness, escalation rates and remediation speed, and report on them with the same rigor as financial metrics.
This reframes the role of the Chief Compliance Officer and brings compliance into the core executive agenda, requiring resourcing and prioritization at the highest level.
The Time to Build Is Now
The regulatory landscape won't wait for firms to finish internal debates about prioritization. The firms that will emerge from this period with stronger compliance programs and competitive advantage are those investing now in unified, data-driven surveillance infrastructure.
The future of financial integrity belongs to firms that move beyond compliance intent to verifiable performance. Navigating MAR, MiFID II and EMIR 3.0 while simultaneously mastering AI governance and cross-domain surveillance requires more than policy; it requires operational precision.
Most importantly, compliance transformation in capital markets isn't purely a technology project. It's a business transformation that touches data architecture, operating models, governance structures and organizational culture. Managing such sweeping transformation requires the discipline to manage that complexity across all dimensions simultaneously, executing with the precision that regulatory deadlines demand.
