Definitions

In plain terms

A bond may promise payments in euros while one of its listings trades in another currency. Denomination and trading currency therefore need separate fields.

Technical

The instrument-level denomination currency must be distinguished from listing currency, trade currency, settlement currency, and reporting currency.

Scope

The exact applicable currency field depends on instrument and data-product semantics.

Examples

  • A governed dataset records instrument currency explicitly instead of inferring it from an ambiguous field.

Common misconceptions

  • Instrument Currency does not have one universal meaning without its stated market, source, and time context.
