Navigate sanctions complexity
Sanctions designations and ownership relationships can change the exposure associated with a financial instrument. For compliance, risk, trading and operations teams, manually combining sanctions lists with securities data can require substantial effort and may make direct and indirect links harder to identify consistently. Organisations therefore need structured information that supports repeatable review without relying on fragmented manual checks across teams.
LSEG Sanctioned Securities Data File brings financial instrument data together with LSEG World-Check sanctions and ownership intelligence. The feed is designed to support the identification of securities associated with explicitly or implicitly sanctioned entities and to fit into established trade surveillance, portfolio monitoring and screening systems.
What are sanctioned securities?
Sanctioned securities are financial instruments associated with entities subject to sanctions measures, either through an explicit listing or through relevant ownership and control relationships. LSEG Sanctioned Securities Data File is a structured sanctions screening data feed for financial instruments. It combines detailed instrument data with LSEG World-Check sanctions and ownership intelligence to help organisations identify potential direct and indirect exposure. Coverage includes equities, fixed income, structured products and derivatives, with information such as sanctions effective dates, instrument maturity dates and the sanctioned issuer name.

Why choose LSEG Sanctioned Securities Data File
Connect financial instruments with sanctions intelligence
Screening teams need to connect sanctions information with the securities held or considered for trading. LSEG combines detailed financial instrument data with World-Check sanctions and ownership intelligence in a consolidated feed. This supports review of direct listings and relevant indirect ownership relationships without requiring teams to assemble the same mapping from separate sources.
Support multiple screening points
Sanctions exposure can change as designations and ownership relationships evolve. The feed provides a consistent data source that teams can apply at relevant screening points while retaining control of their own review processes.
Screen across asset classes
Portfolios can contain different asset classes, each with distinct identifiers and review requirements. Coverage includes equities, fixed income, structured products and derivatives. Structured identifiers, categorisation and keywords help teams discover and filter relevant records across these instruments according to the organisation’s screening approach, internal controls, operating model and defined risk appetite.
Reduce manual data maintenance
Combining changing sanctions information with instrument data can place a recurring maintenance burden on operational teams. The pre-mapped feed is designed for ingestion into trade surveillance, portfolio monitoring and screening systems. Daily updates help keep screening inputs aligned with changes to sanctions designations and support more efficient, repeatable data maintenance across operational workflows.

Use cases
Pre-trade screening
A fund manager assessing a proposed trade needs to determine whether the financial instrument has a direct or indirect link to a sanctioned entity. Fragmented instrument and sanctions sources can make that review resource intensive. LSEG Sanctioned Securities Data File provides a structured, consolidated feed that can be integrated into pre-trade screening. Teams can compare proposed securities with mapped instrument, sanctions and ownership information, then review relevant identifiers and data points. This supports a consistent screening step before execution while the fund manager retains responsibility for its policies, assessment, escalation, governance and final trading decision.
Portfolio monitoring
An asset manager may hold securities whose sanctions status or ownership relationship changes after acquisition. LSEG Sanctioned Securities Data File supports portfolio monitoring by helping teams identify holdings associated directly or indirectly with sanctioned entities. Daily feed updates can be incorporated into established monitoring processes and used to highlight records for review as sanctions designations change. Structured identifiers, categorisation and keywords help analysts filter the data for their workflow. This gives compliance and portfolio teams a consolidated input for reassessing holdings while the organisation remains responsible for interpreting results, documenting review and deciding any required action.
Post-trade review
Trade operations and compliance teams may need to review executed transactions for sanctions exposure and maintain oversight across post-trade activities. The structured feed can be integrated with trade surveillance or screening systems to compare completed trades with financial instruments linked to sanctioned entities. Instrument information, sanctions effective dates, maturity dates and the sanctioned issuer name can support investigation of relevant records. Using one mapped source can reduce repeated manual combination of instrument and sanctions data. Teams still apply their own controls, review supporting information and determine whether escalation, restriction, further investigation or another response is appropriate.
Enterprise-wide screening
A financial institution may need instrument-level sanctions data across compliance, trading and risk management teams, each operating different systems and processes. LSEG Sanctioned Securities Data File provides a centralised, structured feed that can be ingested across departments and used in pre-trade, post-trade, portfolio monitoring and screening workflows. Consistent identifiers, categorisation and keywords support shared data discovery while allowing teams to filter information for their responsibilities. This can reduce duplicated data maintenance and support a more consistent screening input across the organisation, while each function retains accountability for documented review, policy application, appropriate escalation and final decisions.
