Data Standards

We Help to Drive Consistency Across the Industry

Overview

Driving Global Data Standardization

Standardized financial data helps global financial markets to set up more efficient processes, interact systematically and fulfil regulatory reporting obligations.

SIX plays an active role in the standardization of financial data by either driving standardization initiatives or executing official standardization mandates. SIX also provides financial markets with standardized financial information. In addition, SIX acts as a provider of registration services. As the maintenance agency secretariats for the standards CFI, ISIN and the Currency Code, SIX ensures that data standards stay up to date.

It is our continuous ambition to drive best practices in the area of data standards and set clear guidelines for the entire industry. Together with strong partners around the globe we are working toward a common goal: making the work with financial data easier for everyone.

National Numbering Agency

In cases when a data standard requires frequent modification or the maintenance of a code list or when a standard requires the assignment of unique identifier, a maintenance agency or a registration authority may be appointed.

SIX is a National Numbering Agency (NNA) and member of ANNA. In this role SIX registers new instruments and issues a related unique International Securities Identification Number (ISIN) and a Classification of Financial Instruments (CFI).

Maintenance Agency

In cases when a data standard requires frequent modification or the maintenance of a code list (based on the “recipe” provided in the standard) or when a standard requires the assignment of unique Identifier it may be decided that a maintenance agency or a registration authority is required.

The Swiss Association for Standardization (SNV) is the appointed Maintenance Agency Secretariat for the ISO 4217 – Currency Codes standard and the ISO 10962 – Classification of Financial Instruments (CFI) standard. SNV has delegated the related responsibilities to SIX.

ISO 10962 - CFI Maintenance : Get a CFI Code

We Maintain and Update the CFI Code

The ISO 10962 Classification of Financial Instruments (CFI) standard is a recognized standard for describing all financial instruments. It is recognized world-wide by all operators and computer systems in the financial and banking industries. The term "financial instruments" refers not only to classical securities and derivatives but also covers the innovative financial products that have emerged in different markets.

The six-letters-code describes the structure and function of each financial instrument in a consistent way. The code is defined when a financial or referential instrument is issued and remains unchanged during its entire life. However, events such as the changing of voting rights or ownership restrictions decided at a stockholder’s meeting can cause a CFI code to change.

As the maintenance agency for the CFI code, SIX is responsible for managing the modifications and enhancements of the code list. SIX is also responsible for publishing updates in a human- and machine-readable data formats like spreadsheets, pdf, csv, json-lD, ttl).

Current and Past Amendments

Effective from 1 April 2022, the following change will be made to “List one: Currency, fund and precious metal codes”: 

Entity Currency  Alphabetic Code Numeric Code Minor Unit
SIERRA LEONE Leone SLE 925 2

The Sierra Leonean LEONE (SLL) is redenominated by removing three (3) zeros from the denominations. A new currency code SLE/925 representing the new valuation (1’000 times old SLL/694) is introduced on 1st April 2022 for any internal needs during the redenomination process, and is replacing SLL as the official currency code, after the transition period to be determined. During this transition period, both the old Leone and new Leone will be in physical circulation for at least 90 days. The Bank of Sierra Leone will adopt the new code in the local system but SLL/694 shall remain in use until further notice. The Sierra Leonean currency shall continue to be the LEONE and this will not change after redenomination.

Changes to the currency codes lists occur if a currency is created, withdrawn or parts thereof altered.

Update: ISO 24165 for Digital Token Identifiers (DTI)

Currently, SIX is developing a new standard for digital assets that will be published at the end of September: ISO 24165 on Digital Token Identifiers (DTI). Read the news by ISO (News 1 & News 2)

 The scope of DTI issuance covers all fungible digital assets which use distributed ledger technology for their issuance, storage, exchange, record of ownership, or transaction validation and are not a “fiat” currency (as defined by ISO 4217). This also includes digital currencies such as Bitcoins.

Some DTIs have already been assigned based on the draft DTI standard as part of a soft launch. Go to the DTIF Registry Search.
