Securities data in OpenSanctions

Our database contains multiple methods for making connections between companies and instruments described on sanctions lists, and asset information.

International Securities Identification Numbers (ISINs) are not the native language of the sanctions world: the vast majority of sanctioned companies are private, and do not issue tradeable securities. Instead, companies are more commonly identified by their name, jurisdiction and registration number on sanctions lists. The US Treasury does identify a very small set of ISINs/ticker symbols directly (see: search result, 238 at time of writing).

Data sources

OpenSanctions expands the government-published sanctions lists with data from other sources. This way, we include securities definitions (and ISINs) from the following sources:

  • Global Legal Entity Identifier Foundation (GLEIF) is the coordinating body for the assignment of LEI codes. They also maintain a mapping of all companies who have an LEI code and the ISIN codes issued to those organizations. This is helpful with banks and large funds.
  • The National Settlement Depository (NSD) of the Russian Federation publishes information about the assignment of ISIN codes to Russian securities. These are subject to US Executive Order 14071.
  • LSEG PermID are included to connect the entities to Refinitiv datasets. We include both the PermID and RIC (Reuters Instrument Code) identifiers.
  • We also enrich securities with OpenFIGI identifiers, which helps to easily link them with Bloomberg datasets.

We hope to add more sources to the system in the near future. If you wish to suggest a relevant dataset which we can legally include in OpenSanctions, please get in touch.

Using the data

On a technical note, OpenSanctions does not consider ISINs to be attributes of companies. Instead, each ISIN is assigned to a Security object, which in turn links to its issuer (a Company object).

To simplify this, we are publishing a CSV table export of all sanctioned companies (using the lists published by the US, EU, UK and Switzerland) with their securities identifiers - LEI, ISINs, RICs and PermIDs inlined for easier analysis.

We're happy to generate a other representations of this data upon request.
