The Securities Superintendency of the Central Bank of Paraguay (BCP) has issued Circular SV.SG. No. 016/2026, setting out specific criteria for updating the identifiers used by supervised entities in the BCP’s database of persons (Base de Personas).

The measure forms part of the implementation of the Regulations on the Identification and Registration of Persons in the Securities and Products Market, approved by Resolution SV.SG. No. 0013/2026.

Although primarily operational, the measure has significant implications for regulatory compliance and the management of client information.

What does the circular provide?

The Superintendency reiterates that the BCP’s database of persons is the single source of identification and that each person must have only one record.

The circular establishes an order of priority for the documents used to identify individuals: first, the identity card; second, the permanent residence certificate; and third, the non-resident person code.

Entities must therefore review their internal records and update identifiers where a person holds a higher-priority document than the one originally used.

They must also avoid creating duplicate records and use updated identifiers in the information submitted to the Superintendency.

What are the implications for the market?

The measure directly affects brokerage firms, investment fund management companies and securities depositories.

In practice, entities must review the consistency of their client databases, identify potential duplicate records and ensure that their regulatory reporting systems use the appropriate identifiers.

This may require coordination among compliance, operations, technology and client service teams.

A regulatory law perspective

Information quality has become a fundamental component of financial supervision.

Consistent identification of clients and market participants improves transaction traceability, reduces discrepancies and strengthens the integrity of the information systems used by the regulator.

Implementing these changes also requires clear internal procedures for updating data, retaining supporting documentation and avoiding errors during record migration.

Entities should therefore treat identifier updates as part of their compliance and corporate governance systems, rather than solely as a technology requirement.
