Dual sided reporting has the potential to provide regulators with very accurate and timely aggregated and specific market exposures. The Unique Transaction Identifier (‘UTI’) is the link between the same trade reported separately by each party, and enables data to be properly analysed by regulators, by preventing double counting and identifying reporting errors.
In the absence of accurate UTI matching, reported data will become misleading or confusing; and industry consensus is that matching rates remain extremely low.
The pool of UTIs is ginormous! The odds of accidentally creating a duplicate of a truly randomly assigned UTI – or a collision – are incredibly low. Consider there are 183 x 10^80) combinations in a 52 character alphanumeric field. That’s 183 with 80 zeros.
Perspective on this number is difficult, but let’s try:
- In order to use the entire set of UTIs available, in the time since the earth was formed until now, we would need to issue 127 billion,billion,billion,billion,billion,billion,billion every second.
- If every grain of sand on earth were an earth and every grain of sand on those earths were an earth and then, finally, every grain of sand on all those earths were an earth, then the count of every grain of sand on all those earths would approximate the pool of available UTIs.
What does this mean? A properly randomly constructed UTI will most likely be unique. Most sell side firms have some method of construction – which maybe simple as using a sequential reference prefixed with an LEI – that will most likely be unique, based on industry protocols.
The challenge, however, remains for OTC market participants to accurately, securely and efficiently pair trades with their counterparty and share UTIs for regulatory reporting.
