Hedges and stairs

The garden effect: why client risk never stands still

17 September, 2026

Keeping on top of a garden is an ongoing job. If left unchecked, hedges can gradually become overgrown, encroaching paths and obscuring what was once visible. This principle applies to managing client risk, where regular maintenance helps ensure records continue to reflect clients and their risk profiles. 

Many financial services firms devote significant time and resources to onboarding clients. They undertake extensive due diligence, assess risks, and complete customer files in line with regulatory requirements. At that point, the client file often represents a comprehensive picture of the customer and their risk profile. But neither clients nor their risks stand still. Ownership structures change, business activities expand, wealth grows and operations become more complex as businesses enter new jurisdictions. Over time, a client may look very different from when they were onboarded.
 

When client files fall behind

Recent regulatory findings in Guernsey have repeatedly highlighted the importance of maintaining an up-to-date understanding of customers. In many cases, concerns do not arise because firms failed to obtain information at the outset. Instead, issues emerge because firms have not updated client files as circumstances change.

Just as an overgrown hedge rarely becomes a problem overnight, compliance weaknesses often develop gradually.

A single overdue review may not seem significant. An outdated source of wealth document or a missing risk assessment update can appear minor in isolation. However, these issues can accumulate, creating a backlog of client records where risk ratings may no longer reflect current circumstances, documentation may have expired and different systems may hold inconsistent information.

What started as a manageable maintenance exercise can evolve into a substantial remediation project.
 

Beyond remediation

Increasingly, financial institutions, fiduciary businesses and investors are acquiring operations in multiple jurisdictions. Whether a bank is purchasing a trust company, a fund administrator is integrating a competitor, or an international group is expanding through acquisition, one question inevitably arises:

"What does the client book actually look like?"

Understanding the quality of client data, the completeness of CDD records and the accuracy of risk classifications can form an important part of transaction due diligence and post-acquisition integration, giving organisations a clearer picture of what they are taking on and any gaps they may need to address.

However, for firms managing large client populations, keeping thousands of files current can place considerable pressure on internal teams, particularly alongside day-to-day regulatory and compliance responsibilities.

Our team supports firms undertaking extensive CDD remediation programmes, customer file reviews, risk reassessments and data quality exercises. By combining the expertise of our specialist teams across our global network with local regulatory knowledge, we can deliver at scale while ensuring the work remains aligned with local regulatory expectations. Alongside this, we also act as a Skilled Person in the UK and Channel Islands, providing independent expertise and assurance where regulators or businesses require a thorough understanding of risk, controls and customer populations.
 

Keeping risks in check

As with maintaining hedges, maintenance is rarely the most exciting task. Yet it is often the work that prevents larger issues from developing.

Firms that view client risk as dynamic rather than static are better positioned to identify emerging issues, respond to changing circumstances and address gaps before they accumulate. Ultimately, good maintenance means knowing that the information you hold still reflects the client you have today.
