I first learned about ISO 20022 some 18 months ago. I remember first thinking about the name. I said to myself this new payment standard must be intended to replace the 20021 different formats the global financial community uses today for payments. Unfortunately, while perhaps very fitting, that is not the origin of the name. However, that is the intention. While there probably are not 20,000+ standards yet, it is not an understatement to say that there are hundreds if not over a thousand in use today.
Why are there so many payment standards?
Banking, like most service sector segments, has historically been a business that focused on local markets. It is only within the past 20 years, that regulations changed so that banks could easily operate within more than one US state or that banks could economically operate in multiple countries within the EU. As a result, when electronic funds transfer and payment technologies were introduced in the 1980s, each country created their own technology standards in isolation. Message formats were standardized based upon the central clearing and settlement systems operated by each country’s central banks. For example, in the US, Federal Reserve’s ACH and FedWire; in the UK, BACS and CHAPS; in France, SIT and so on. Today, not only do we have different payment message structures for each country, but each country also has different file formats for each payment type (e.g. check, automated clearinghouse (ACH) and wire transfer). And it doesn’t stop there. It is not only the message structure that differs between payment files, but the content as well. For example, a payment in one country may require a complete street address, city name and postal code, the same type of payment in another country may only require the postal code. To complicate matters even further, the non-bank corporations tend to utilize a different set of standards (e.g. ANSI X.12 , EDIFACT, OAGi) to exchange payment information with their banking partners.

Numerous organizations including OAGi, RosettaNet and TWIST have each made an attempt to standardize payment message formats at varying levels. ISO 20022 is the most promising effort yet towards a common payment information standard.
What is ISO 20022?
ISO 20022 is also known as UNIFI (UNIversal Financial Industry message scheme). The official definition from www.iso20022.org is “UNIFI provides the financial industry with a common platform for the development of messages in a standardized XML syntax, using:· A modelling methodology (based on UML) to capture in a syntax-independent way financial business areas, business transactions and associated message flows;· A set of XML design rules to convert the messages described in UML into XML schemas.” Although, the discussion above describes ISO 20022 in the context of payments, the standard has ambitions which extend far beyond that domain. The scope of ISO 20022 is all financial messages including Payments, Foreign Exchange, Trade Finance and Securities. And the standard is beginning to gain widespread adoption as organizations such as TWIST, OAGi, RosettaNet and SWIFT have begun to embrace it.
Who is using ISO 20022? · SWIFT – SWIFT is embracing ISO 20022 as the preferred XML format for messages exchanged on the SWIFTNet service used by over 8,000 financial institutions in over 200 countries to exchange financial transactions.· SEPA - ISO 20022 is one of the key unifying standards that will harmonize payment technologies and standards throughout the European Union with the Single European Payments Area (SEPA). For example, ISO 20022 will be a foundational standard for TARGET 2 (Trans-European Automated Real-time Gross Settlement Express Transfer System), the next generation, real time settlement system for Pan-European payments.
· Vendors – Financial application vendors including the larger ERP players Oracle and SAP are building ISO 20022 into their products. You can expect niche treasury workstation, accounts payable and accounts receivable platform vendors to adopt the standard as well.
· Corporations – Several innovative treasury departments have announced plans to standardize on ISO 20022. Corporations can use this one standardized payment format across all geographies and all financial institutions. Two notable examples of corporations adopting ISO are:
· Merck - Several of the most innovative corporations are beginning to embrace ISO 20022 already. Merck is in the process of re-architecting its global treasury and payment operations as it moves to a single SAP system worldwide. In addition to deploying ISO 20022, Merck is also leveraging the new SWIFT S.C.O.R.E. model for bank connectivity. The combined use of ISO and S.C.O.R.E. can radically simplify the technical interfaces for corporations and their banks, not to mention significantly reducing their costs. There is a good article on Merck’s strategy in the September 2007 issue of Treasury & Risk (http://www.treasuryandrisk.com/topic/tech/treasury/1055).
· Sun Microsystems - At this year’s SWIFT SIBOS conference, Bank of America and Sun Microsystems announced that they were embarking on a pilot project involving ISO 20022 and SWIFT S.C.O.R.E. Sun will send credit transfers to the bank and receive the associated payment status reports in return. More details can be found in Sun’s press release at http://www.sun.com/aboutsun/pr/2007-10/sunflash.20071002.1.xml . Even the Wall Street Journal picked up this release.
The US clearing systems haven’t announced a strategy for ISO standard yet. Here is a good article from GTnews on the potential adoption of ISO 20022 by the US clearing systems - http://www.gtnews.com/article/6718.cfm.
Investigate further
If you are not familiar with this new standard, I would encourage you to take a look at it. If you are a company with multiple banking relationships, adopting ISO 20022 may significantly simplify your electronic interactions with financial institutions.
Unfortunately, there isn’t a lot of easy-to-read information available on this new standard. Wikipedia has an entry - http://en.wikipedia.org/wiki/ISO_20022 that is essentially useless. There is a lot of good information www.iso20022.org, but the content is more applicable to technologists familiar with the financial services industry. SWIFT hasn’t published much that is publicly available. There are a few good articles on www.finextra.com and, of course, www.gtnews.com. I will add more posts with insights on this topic as we see further adoption in the marketplace.
