TS ISO 18774

TS ISO 18774 defines and describes the rules for building a Financial Instrument Short Name (FISN) for securities and related financial instruments. The technical purpose is to replace long, market-specific product names with a short designation created according to a defined structure.

In general technical terms, a short-name scheme helps organise instrument identifiers in a compact, consistent form. It is useful where the same instrument may appear across trading, post-trade, reference-data, and reporting systems in different naming styles or languages. The standard itself is about the construction of the short name; it does not determine the instrument’s value, suitability, or market performance.

What the short-name structure is for

Structured short names support data consistency across systems and jurisdictions by expressing key identifying elements in a controlled format. In large financial markets, full instrument names can be too long, inconsistent, or influenced by local conventions. The FISN concept provides a common naming framework that improves readability and machine handling without turning the name into a classification code.

• The standard defines and describes an internationally valid system for constructing short names.
• Its scope covers any kind of financial instrument within a defined structure.
• The intent is consistent naming across markets and data systems.
• It addresses naming structure, not valuation, trading rules, or product classification.
