Study on trading and post-trading prices, costs and volumes – Frequently Asked Questions
What is the purpose of this study?
This study enables the European Commission to determine public policy on the basis of both sound analysis and a thorough understanding of the market. It enhances transparency and contributes to the Commission’s and market participants’ understanding of the market. Further information about the Commission’s work in the area of trading and post-trading can be found on the Commission's website ( )
Why has the Commission asked Oxera to undertake this survey?
The European Commission decided to engage a consultancy to conduct this study. Oxera was awarded the contract after submitting a proposal in response to the Commission’s open invitation to tender. Oxera is an independent economics consultancy with extensive experience in undertaking economic and financial analysis in the financial services sector.
What are the main findings of the study?
The main findings of the study have been summarised in the executive summary of the report.
What is covered by the study?
This study covers equities and fixed income securities in dematerialised or immobilised form. Only (equity) trades undertaken on a commission basis are included (around 97% of trading, measured in terms of value, in equities on behalf of clients in Europe is conducted on a commission basis).
The Commission requested a classification of three types of financial centre: major, secondary, and other:
Which time period is covered by the survey?

In accordance with the non-disclosure agreement signed by Oxera and the survey participants, the name of survey participants is not disclosed (see “ Why is not all data presented in the report?”)
What part of the market is covered by the survey?
In most financial centres, there were sufficient responses to allow for a comparison of prices, costs and volumes over time. The market coverage is as follows:
Why is not all data presented in the report?
Most of the data requested in the survey is not typically available in the public domain and is considered confidential. The data provided has therefore been covered by a non-disclosure agreement (NDA), which sets out the terms and conditions under which any of the data supplied can be used in public domain reports. In accordance with the NDA, the report presents survey respondents’ data in aggregated form only (i.e. aggregated across firms and, at some levels in the value chain, across financial centres).
Where there are few survey respondents, no data in absolute terms can be presented. However, to allow for comparison over time, the data will be presented in relative terms (in an index form) in the second and any subsequent reports.
To present results of the baseline in this report, some data is aggregated across financial centres, and some is presented in ratios and indices. The name of survey participants is not disclosed.
For infrastructures where time-series data is available, only the magnitude of the changes over time is reported on a financial centre basis. Since this information may relate to only one supplier, and the identification of the data subject may be obvious, checks have been undertaken to ensure that the data provider agrees to include the information, in accordance with the NDA.
When was the study conducted?
The study was conducted between October 2007 – June 2009.
When will the next study be conducted?
Oxera will shortly start to collect the data necessary to conclude the next study by autumn 2010.
