Sources & method
Every value comes from a public source, such as Swift’s ISO 9362 BIC directory, GLEIF or the OFAC and EU sanctions lists. Most sources are matched on a BIC or an LEI, not on a name.
Swift GPI membership is matched on names and is indicative. A missing sanctions match does not mean that no listing applies. Always screen against the official lists.
The sanctions facts on this page cover the BIC and its LEI only.
An institution is one entry in the directory: a BIC8 in Swift’s directory, or a firm on a tracked register that holds no BIC. Licences held by an institution with a BIC are shown on its page.

- Overview, leadership, regulators and events—researched per institution by an AI model with web search, from the institution's own website and reports, regulators, company registers and news. Figures, people and events link to their source, and each card shows the research date. AI research can be wrong or out of date, so check key facts at the source.
- Images—logos and photos from Wikimedia Commons (credited with their author and licence) or from the institution's own website, where Wikimedia has none. Elucidate keeps a copy of each; the links lead to the source and the original image. Logo: prosperitybankusa.com (official website) · original.
Assess the financial crime risk behind a BIC
A BIC identifies an institution; it does not assess it. The Elucidate FinCrime Index (EFI) is an independent score of the financial crime risk of banks, built for correspondent banking and counterparty due diligence.
