Open Ownership ¦ Research Symposium Synthesis Report: Evidence and Impact of Beneficial Ownership Transparency

Beneficial ownership transparency is moving beyond AML – and the evidence is catching up

Beneficial ownership transparency has long been treated as a core anti-money laundering tool, but the latest research synthesis from Open Ownership shows that its impact is broader than that. The report, based on a February 2026 research symposium, makes a clear point: if policymakers want effective reforms, they need to measure what beneficial ownership data is actually used for, what changes it creates, and where it falls short.

That matters for financial crime professionals because the value of beneficial ownership information is no longer limited to identifying shell companies and hidden controllers. It is increasingly being used in tax enforcement, public procurement, environmental oversight, media accountability, and even sport. In other words, ownership transparency is becoming a general-purpose integrity tool.

Evidence of value is growing, but it needs careful reading

One of the strongest messages from the symposium was that impact measurement is essential if reforms are to survive. A register may look like progress on paper, but unless the data is used, maintained, and trusted, it will not deliver much in practice.

The report highlights a UK government study estimating that beneficial ownership information in Companies House has value of about GBP 4,400 per organisation per year for the private sector and around GBP 2,600 per user per year for the public sector. Findings like this can help build political support and make the case for investment in better data systems. But they also need caution. Value estimates do not automatically prove that beneficial ownership transparency stops financial crime. In some cases, they may show that legitimate actors changed behaviour in response to disclosure rules, while the intended illicit actors simply adapted.

That distinction matters. A decline in investment from opaque jurisdictions may indicate deterrence, but it may also reflect the exit of legitimate business rather than the exposure of criminal capital. For financial crime monitoring, the lesson is that data needs to be interpreted in context, not treated as a simple scorecard.

"Beneficial ownership transparency is proving its value far beyond anti-money laundering, with growing use in tax, procurement, and broader corporate accountability. The latest research also shows that impact depends not just on having a register, but on whether the data is accurate, accessible, and actually used.

At the same time, progress remains uneven because of fragmented legal rules, restricted access, and weak verification in some jurisdictions. The next stage will likely depend on better measurement, stronger political will, and more practical links between company data and asset transparency."

Beneficial ownership data is being used in more ways than before

A major takeaway from the symposium is that beneficial ownership data is now being applied well beyond AML. In Ecuador, research presented at the event linked disclosure requirements and a tax on firms owned through tax havens to a reduction of tax haven owned firms and a rise in domestic corporation tax receipts. In Chile, the use of beneficial ownership data in state contracting, combined with stronger analysis and public information efforts, appears to have reduced conflicts of interest in procurement.

These examples matter because they show how ownership transparency can support detection, prevention, and deterrence across multiple risk areas. For compliance teams, investigators, auditors, and regulators, that means beneficial ownership data should be seen as an input into wider risk analysis, not as a standalone registry exercise.

The report also points to newer applications in media ownership, energy sector accountability, and environmental compliance. That trend suggests that beneficial ownership transparency may become part of the basic infrastructure of corporate oversight, similar to company registers, tax records, and procurement databases.

The quality of the data still varies too much

The report is equally clear about the limits of current systems. Even where beneficial ownership registers exist, rules differ widely across countries and regions. Data quality, verification methods, exemptions, and enforcement all vary. Those differences matter because poor-quality data can create a false sense of security.

In some jurisdictions, companies are mainly responsible for verifying their own disclosures. In others, there is little or no third-party verification. Some systems contain large exemptions, such as Kuwait’s September 2025 decision to exempt all government entities from disclosure, leaving major public sector actors outside transparency frameworks.

For financial crime work, this is a reminder that access to a register is not the same thing as access to reliable intelligence. A register with missing, outdated, or self-reported information can still be useful, but only if users understand its limits.

Access to data is becoming a major bottleneck

A particularly important theme in the report is restricted access. Since the EU’s Sovim SA ruling (joined cases C-37/20 and C-601/20, WM and Sovim SA v Luxembourg Business Registers), many researchers have faced much tighter conditions for obtaining beneficial ownership data. Requests can be rejected, access can be narrow, and even approved access may only cover selected records or fields.

This has direct consequences for financial crime research and reporting. If journalists, civil society groups, and academics cannot access the data, it becomes harder to test whether reforms are working, to identify abuse, or to expose weak enforcement. The report notes that some researchers have had to abandon projects or buy third-party data just to continue their work.

One proposed response is to stop framing the debate as privacy versus transparency and instead think of it as transparency versus secrecy. Another is a tiered access model, where authorities and regulated entities receive full access, researchers and journalists get verified access based on legitimate interest, and the public receives basic information. For anyone working in financial crime prevention, that debate is not abstract. It will shape how quickly suspicious structures can be found and how well misuse can be exposed.

Momentum for reform is fragile

The report also shows that reforms often gain traction after a crisis, then lose momentum. The Panama Papers, COVID-era procurement scandals, Russia’s invasion of Ukraine, and FATF pressure have all helped push transparency forward in different places. But once the immediate crisis passes, political support can weaken.

That creates a familiar risk in financial crime policy. Governments may launch a register to satisfy an external review, only to reduce ambition later through subtle changes to exemptions, access rules, or verification requirements. The register still exists, but its usefulness declines.

The report argues that durable reform needs wider coalitions across public bodies, private sector users, investigative actors, and civil society. That makes sense. If ownership data is used for procurement, tax, due diligence, sanctions screening, environmental enforcement, and investigative work, there are more institutions with a stake in keeping the system functional.

Asset transparency is the next frontier

One of the most interesting parts of the report concerns beneficial ownership transparency of assets. Up to now, most systems have focused on legal vehicles such as companies and trusts. But asset ownership can also be used to hide wealth, move value across borders, and obscure links to crime.

Real estate is the clearest example. Research presented at the symposium showed that ownership opacity in places like Milan and France is not limited to luxury property. Higher-risk purchases can appear across price ranges, though the most expensive properties are often more exposed to offshore or opaque ownership. That is highly relevant for money laundering, sanctions evasion, and illicit wealth concealment.

At the same time, the report makes clear that asset transparency is more complex than company transparency. Assets can involve multiple rights and different authorities, and the purpose of many asset registers is legal certainty rather than financial transparency. In sectors like fisheries, for example, ownership, control, licensing, and usage rights may all sit with different parties. That makes it hard to decide what should be recorded, by whom, and at what level of detail.

The policy challenge is balance

The report does not suggest a simple answer for asset transparency. Some contributors argued for more ambitious reporting, potentially across a wider range of asset types. Others warned that aggressive enforcement could create privacy concerns or open the door to abuse in weaker governance environments.

For financial crime professionals, the main lesson is that asset transparency is likely to grow, but it must be designed carefully. Strong systems should improve the ability to detect hidden wealth without creating unnecessary compliance burden or weak safeguards. In many cases, the better path may be to strengthen existing land or asset registers and link them with beneficial ownership registers, rather than building entirely new systems from scratch.

What this means for the financial crime community

The report is useful because it reflects where the field is now. Beneficial ownership transparency is no longer a niche AML reform. It is becoming a cross-cutting integrity measure, with uses in tax, procurement, environmental oversight, media, and asset tracing. But the evidence base is still uneven, access to data is under pressure, and implementation standards remain inconsistent.

For financial crime practitioners, that means three things. First, beneficial ownership data should be treated as a powerful but imperfect source. Second, reforms need better measurement if they are to survive political cycles. Third, the next wave of progress is likely to come from linking company data with asset data, provided access and verification problems can be solved.

The report’s message is straightforward: transparency is only valuable when it can be used, tested, and enforced. For the financial crime sector, that is where the next set of gains – and the next set of failures – will be decided.
