The financial crisis has pushed many countries to widely reform their economic system. International organizations have cooperated to improve important international standards and monitoring regulations for initiating mechanisms and rules of the global financial market to be better worked. Moreover, there is a concern of international coordination in order to report related statistic data, have standards linking each other completely, correctly, and in time for protecting and solving any crisis that may happen.

Thailand is also affected by the data problems. Collected data of financial instruments are in many organizations. Those organizations collect by their working usage purposes and have different standards and definitions that making the linkage and exchange of financial instrument data among both domestic and international organizations become difficult. Hence, the setting of data standards is the main mission that is essential for the establishment of the TFIIC. There is the regulation setting of classification (CL) codes and many definitions in order to have CL codes and definitions in the same standards and mostly rely on international standards. International standards are specified from many organizations. Standards that many organizations around the world select are ISO data standards by ISO (International Organization for Standardization) which is the international organization for standardization. This organization has main purposes for enhancing the international standard setting and related activities for developing international economy, trade, and industry.

Examples of CL codes that the TFIIC uses:

• International Securities Identification Number (ISIN Code): ISO 6166
• Classification of Financial Instruments (CFI Code): ISO 10962
• Code of Exchange and Market Identification (MIC Code): ISO 10383
• International Standard Industrial Classification of All Economic Activities (ISIC Code)
