Frequently asked questions

Answering some of our customers' common questions since the release of EMIR.

Who is required to report?

Under EMIR, all counterparties to all derivativeS transactions are required to report. Examples of companies that need to report include:

  • Financial and non-financial counterparties; and
  • Central Counterparties and Clearing Members.

However, a counterparty outside the EU does not have the obligation to report to a trade repository.

Which activity needs to be reported?

In terms of transactions that need to be reported, the following are in scope:

  • Cleared and non-cleared exchange-traded derivative (ETD) and over-the-counter (OTC) traded contracts, with no exception on derivative products
  • Lifecycle events (e.g. give-ups, partial termination etc.)
  • Reporting of exposure: Daily reporting of valuations and collateral posted by FCs and NFCs above the clearing threshold

What data elements need to be reported?

All derivatives positions must be reported to a trade repository authorised by ESMA by the end of T+1. The information the needs to be reported includes:

  • Common data
    General common information related to contract type, contract information, transaction details, risk mitigation, clearing, modification to contract
    Common data specific to each type of products (e.g. Interest rates, foreign exchange, commodities, energy, options, credit derivatives)
  • Counterparty data
    Information related to the counterparties of the contract as well as to the clearing member, broker entity, CCP, reporting entity, beneficiary etc.
  • Collateral data (reporting of identifiers)
    Legal entity identifier (LEI) for legal person identification, UPI or CFI for product classification, ISIN for product identification and bilaterally agreed UTI for Trade IDs, until global UTI is available

Since the implementation of the revised RTS as from the 1 November 2017 the regulation defines 129 data elements to be reported. Depending on the type of contract, those data elements are mandatory, conditional or optional.  

What changed with the revised RTS/ITS under EMIR?

Since 1st of November 2017 the revised RTS/ITS are entered into force. These new technical standards significantly changed the regulation and especially the reporting of derivative contracts.

 The main changes can be categorised as following:

  • Significant increase in the data fields reportable under EMIR, especially in regards to the reporting of collateral and valuation. Under the revised RTS/ITS, it is also required to report additional information on credit derivatives and interest rate derivatives.

  • Furthermore, EMIR introduces an additional field “Level” to indicate whether the reporting is done on a trade level or a position level.

  • Based on the legal texts, the number of fields has increased to 129 fields in total (including counterparty, common and collateral data). However, this does not include a small number of REGIS-TR proprietary fields.

    Please also note, that certain fields have been erased or renamed to better reflect market practices.


On 4 May 2017, an amendment and simplification of the regulation (EU) No 648/2012 in the context of its Regulatory Fitness and Performance (REFIT) programme has been proposed by ESMA, to address disproportionate compliance costs, transparency issues and insufficient access to clearing for certain counterparties.  Apart from several changes in regards to the clearing obligation, the main changes have been made in the reporting obligation in terms of entities having the responsibility to report as well as the reportable transactions.

From a reporting perspective the proposed changes can be summarised as following: 

  • Transactions between a Financial Counterparty (FC) and a Non-Financial Counterparty not subjected to the clearing obligation (- NFC) will now be reported by the Financial Counterparty (FC) on behalf of both counterparties.
  • Intragroup transactions will no longer have to be reported if the parent company is a NFC
  • Entities that became subject to EMIR after the reporting obligation came into effect, were subject to the back-loading by the end of 12 February 2019.This obligation has been removed with REFIT.
  • Commission proposed ETDs to be reported by the CCP on behalf of both counterparties.

Inter-TR Portability  

ESMA published its Final Report - Guidelines on transfer of data between Trade Repositories, also known as Portability. In the document, ESMA detail the steps which must be taken when:

A reporting firm wishes to move from its existing TR to a new one, or

  • A TR withdraws from the market
  • This new portability protocol needs to be applied by all TRs since the 31st of December 2018.

The document creates a clear charter between the reporting firm, the old TR and the new one, cuts across commercial constraints and competition, and puts at its heart the reporting firm and its right to access a free market of trade repositories - exactly as envisaged under EMIR.

For firms considering whether and how to move from their existing TR to a new one, the following aspects are highly informative.

The reporting firm, the old TR and the new TR will agree a binding migration plan between them detailing, amongst other things:

  1. The scope of the data to be transferred,
  2. The roles of the three parties involved in the transfer,
  3. The timeline for the transfer,
  4. Controls to ensure the integrity and confidentiality of the data during the transfer process, and
  5. How transferred data should be re-processed through the Inter-TR reconciliation.
  • The transfer of data between trade repositories will be carried out entirely between the old and new TR. Reporting firms will not have to cancel or error data at their old TR, nor re-report data at the new one.
  • From a technology perspective, TRs will transfer data using the ISO20022 format to ensure the ongoing quality of the data reported.
  • ESMA details how the transfer of large datasets, which may take more than one day to complete, should be performed so as to maintain the integrity of the historical and BAU reporting.
  • With regards to the costs to reporting firms of porting to a new TR, ESMA specifically stated that,"there is a cost related to the transfer of data that will be borne by the old TR", nonetheless "the fees should not be set too high so as to disincentivise TR participants from transferring their derivatives to another TR".
  • Clarity on portability can only foster competition between TRs, driving improvements in service quality, product innovation and ensuring competitive pricing. 
  • Firms who have historically reported to whichever TR was most ubiquitous in either their part of the world, or their business line, are now re-evaluating that choice based on the total cost of reporting, their ability to demonstrate their compliance with the reporting regulations, and in light of their need to consolidate their systemic risk reporting across not just EMIR, but now also the FinfraG and SFTR regimes.
