ISIN Quest: Retrieves ISINs for Financial Instruments

Improve your MIFID reporting by easily retrieving reportable ISINs for your transactions through Qomply's ISIN Quest.

Regulators are now actively contacting firms regarding their use of Instrument Classification Codes (CFI Codes), and descriptive fields, instead of using the reportable Instrument Identification Numbers (ISINs).

The Problem

In MiFID reporting, the regulators expect firms to take all reasonable steps to report ISINs for instruments as opposed to using descriptive fields such as Instrument Full Name and Instrument Classification Code (CFI Code). Recent regulator activity suggests there is ongoing interest in this particular MiFID reporting issue. This has led to firms having to remediate millions of transactions - retrospectively assigning a reportable ISIN in place of the instrument description.

Many firms have encountered challenges in accurately identifying specific ISINs for instruments due to the difficulty in accessing data. This is particularly common for firms dealing in OTC securities, where ISINs may not always be readily available.

The Solution

ISIN Quest enables firms to retrieve ISINs for instruments in a click by simply inputting a CFI Code and trade date.  

ISIN Quest automates the retrieval of reportable ISINs for your transactions by leveraging data from both ANNA DSB and FIRDS (UK and ESMA).

Users simply upload a list of descriptive fields (CFI Codes) and trading dates. The reportable ISINs for each trading date are returned. The entire solution can also be accessed programmatically for large transaction volumes.

ISIN Quest accepts both CSV and XML formats, providing versatility in data handling. This means, users can input 65-field MiFID reports OR only a few key fields. Results are returned immediately in a standardised format, enriched with additional columns containing comments alongside reportable ISINs for each transaction.
