We are excited to share Connecting ownership data: Practical pathways to tackle cross-border financial crime. This final report sets out the findings and recommendations of the Taskforce on Interoperable Beneficial Ownership Data , co-convened by Open Ownership, the Global Coalition to Fight Financial Crime (GCFFC), and London Stock Exchange Group (LSEG) Risk Intelligence. Sincere thanks to all those who have contributed to the report and the Taskforce, which brought together over 50 experts from the private sector, international bodies, and civil society.

Anonymously owned companies enable 70% of major corruption cases. While over 100 jurisdictions now operate beneficial ownership (BO) registers, data remains siloed. The report clarifies key concepts, examines practical scenarios for implementation at global, regional, and bilateral levels, and identifies actionable recommendations to advance financial integrity.

Three Pillars of Interoperability

True data interoperability requires synchronized progress across three dimensions:

• Semantic: Ensuring data means the same thing across different jurisdictions.

• Technological: Providing machine-readable infrastructure, such as secure APIs.

• Governance: Establishing legal clarity, trust frameworks, and sustainable financing.

Five Future Scenarios

The report identifies five practical pathways to translate interoperability into practice:

1. A centralized global international register connecting multi-jurisdictional data.

2. A single international search platform enabling decentralized queries.

3. Coordinated bilateral or multilateral exchange between competent authorities.

4. Direct register-to-register data exchange to map cross-border ownership chains.

5. Widespread publication of data using a common, structured format like BODS.
