Regulatory Technology (RegTech): What It Is and Why Banks Are Investing

The compliance cost of operating a regulated financial institution has grown dramatically over the past decade. Following the 2008 financial crisis and the subsequent wave of global regulatory reform, financial institutions have faced a sustained expansion in the breadth and depth of their compliance obligations — more regulations, more jurisdictions, more data requirements, more reporting, and more personal accountability for senior managers. The headcount-based approach to managing this growing burden has reached its limits: hiring more compliance staff does not scale indefinitely, and manual processes do not improve in quality simply by adding more people.

RegTech has emerged as the solution to this structural problem. By applying technology — automation, AI, cloud infrastructure, and data analytics — to compliance processes, RegTech enables financial institutions to do more compliance work, more accurately, at lower unit cost, and with better audit trails than manual approaches can deliver.

1. What RegTech Covers: The Core Use Cases

2. Why Banks Are Investing: The ROI Case

The investment case for RegTech is increasingly straightforward for financial institutions that have quantified the cost of their current compliance operations. The unit economics of manual compliance — cost per customer onboarded, cost per alert investigated, cost per regulatory report filed — are unfavourable compared to technology-enabled alternatives by a significant margin at any meaningful scale.

Compliance Headcount Costs

A compliance analyst in the UK cost approximately £45,000–£65,000 per year in salary, plus employer NI, benefits, and management overhead — a total employment cost of £60,000–£90,000. That analyst can investigate perhaps 20–30 transaction monitoring alerts per day at adequate quality. A well-calibrated automated system can reduce the alert volume by 50–70%, immediately multiplying the effective capacity of the same team without additional headcount.

Onboarding Cost Reduction

Manual KYC onboarding costs £50–£200 per customer in analyst time, document management, and administrative overhead. Automated KYC platforms typically reduce this to £5–£20 per customer at volume, while simultaneously reducing the onboarding time that affects customer conversion rates. For a fintech onboarding 10,000 customers per month, the saving is material from the first year of deployment.

Regulatory Risk Reduction

The risk-adjusted return on RegTech investment must include the value of regulatory risk reduction. For a firm facing a meaningful probability of an FCA enforcement action — with associated fine, remediation cost, and reputational damage running to tens or hundreds of millions of pounds — the cost of a RegTech programme that materially reduces that probability has an expected return that dwarfs the technology cost.

3. The RegTech Evaluation Framework

Selecting the right RegTech solution requires a structured evaluation process. The following framework covers the key dimensions that compliance officers and CTOs should assess when shortlisting vendors.

Regulatory Alignment

Does the platform explicitly support your regulatory framework? A KYC platform built for US FinCEN requirements may not address FCA MLR 2017 obligations. An AML monitoring solution built for retail banking may not support the investor-level monitoring requirements of investment managers under AIFMD and MiFID II. Regulatory alignment must be demonstrated at the feature level — not asserted at the marketing level.

Integration Architecture

RegTech solutions that cannot integrate with your existing core systems will create data silos rather than streamlining compliance. Assess the vendor's API architecture, existing integration partnerships with systems used in your sector, and the implementation timeline and cost for the integrations you require.

Scalability

Your RegTech investment should be capable of scaling with your business for at least three to five years. Assess the vendor's architecture, their largest existing client by volume, and their documented capacity limits. A solution that requires replacement when you double in size is not a long-term investment.

Audit Trail Quality

The audit trail produced by the RegTech platform is what you will show to the regulator. It must be complete, structured, searchable, and tamper-evident. Review the actual audit trail output — not a demo — and assess whether it would satisfy an FCA supervisory visit or a FinCEN examination request.

Vendor Stability and Support

Compliance technology is mission-critical infrastructure. Evaluate the vendor's financial position, client retention, and support capabilities. A RegTech startup with an impressive product but limited capital runway creates operational and regulatory risk if it ceases operation during a critical compliance period.

4. RegTech and the Regulatory View

Regulators have moved from cautious observation to active encouragement of RegTech adoption. The FCA's Innovation Hub has run dedicated RegTech workstreams and issued guidance on how firms can use technology in their compliance programmes. The FCA has explicitly stated that it welcomes innovative approaches to compliance and that using technology to improve programme effectiveness is consistent with regulatory expectations.

One Constellation's platform spans the core RegTech use cases for financial crime compliance — bringing together automated customer onboarding and KYC, transaction monitoring, and integrated compliance management in a single platform built specifically for the regulatory requirements of banks, investment managers, wealth managers, fund managers, fintechs, and law firms.
