What is the primary purpose of ISO standards in market data such as FIX, Corporate Actions, and LEI?

• A. Improve data privacy
• B. Ensure consistency across markets
• C. Maximize latency
• D. Reduce the number of data vendors

Answer: (B)

Standardization provides a common language and structure for market data, allowing different markets to interpret and use the data consistently. When data like FIX messages, corporate actions notices, and LEI identifiers follow ISO-defined formats and definitions, each data element has the same meaning no matter where it originates. This makes automated processing, cross-market analytics, and regulatory reporting reliable and scalable. For FIX, ISO-aligned formats and field definitions ensure a trade, price, or quote is described the same way across venues and data feeds. For Corporate Actions, standardized event types, dates, and notices prevent misinterpretation of actions like mergers, splits, or dividends. For LEI, ISO 17442 provides a unique, globally recognized identifier that unambiguously ties activities to the correct legal entity, across all markets. This consistency is what enables accurate aggregation, risk management, and automated workflows. Privacy, latency, or the number of vendors aren’t the primary aim of these standards, even though standards can influence those areas indirectly—the core purpose here is interoperability and uniform meaning across markets.
