Europe’s fragmented ETF market is set to gain its first consolidated source of trading data after the European Securities and Markets Authority authorised EuroCTP to operate the EU’s
consolidated tape for shares and exchange-traded funds.
The tape will combine real-time trading information from exchanges, multilateral trading facilities and approved publication arrangements into a single data stream. It will include both pre-trade
information, such as the best available buy and sell prices, and post-trade data covering completed transactions and trading volumes.
The development is particularly relevant to ETFs because the same fund can be listed on several European exchanges, traded in different currencies and bought and sold across multiple venues.
At present, investors and market participants may need to consult several separate data sources to obtain a complete picture of an ETF’s liquidity and trading activity.
EuroCTP intends to aggregate information at two levels. Its more detailed view will separate trading by ISIN, currency and place of listing, while its composite view will combine trading in the same security and currency across different venues. This should make it easier to see liquidity that might otherwise appear fragmented between exchanges.
The system is expected to collect data from approximately 200 order books and reporting venues and cover more than 35,000 instruments and composite listings. It has been designed to process as many as three billion messages a day.
Retail investors, academics, civil society organisations and regulators will be able to access the consolidated data free of charge. Professional users will pay what ESMA described as a reasonable fee and will be permitted to use the information internally and when serving clients.
ESMA selected EuroCTP as its preferred provider in December 2025 but the latest decision gives the company the formal regulatory authorisation needed to operate the service.
EuroCTP has been granted a transition period until 30 September to complete the technical and operational arrangements required for launch. It will then operate the tape for five years under ESMA’s direct supervision.
The company is owned by 16 European exchange groups, representing markets across all 27 EU member states. Its shareholders include groups associated with Deutsche Börse, Euronext,
Nasdaq, SIX and the Vienna Stock Exchange, alongside a number of smaller national exchanges.
EuroCTP said trading venues and data-reporting firms have been connecting to its testing environment, while data vendors and redistributors are preparing to integrate the information into their own systems. Potential uses include transaction-cost analysis, monitoring markets and demonstrating that trades have been executed at competitive prices.
Our view
David Batchelor, senior analyst at QuotedData, said: “The introduction of a consolidated tape could address one of the more confusing features of Europe’s ETF market. An ETF may have a single portfolio and ISIN but trade through several listings, currencies and venues, meaning the volume displayed on one exchange does not necessarily represent its overall liquidity.
Bringing those trades and prices together should make it easier for investors to assess where an ETF is genuinely liquid and whether the price available through their broker is competitive.
It may also help smaller ETFs and providers. Trading in these products can appear limited when activity is divided between several exchanges, even where there is reasonable liquidity across the market as a whole.
However, the usefulness of the tape will depend on how effectively the information reaches ordinary investors. Free access is welcome, but the greater benefit may come if brokers and investment platforms use the data to improve their price comparisons, trading information and execution processes rather than leaving investors to interpret a professional market-data feed themselves”.
