A New European Order: Fragmentation Reshapes the Market
Nomura’s Jeremy Bruce summarises the current state of play in terms of European liquidity venue fragmentation, and focuses specifically on venue ownership and geographical concentration of equity execution venues.
Ownership and Location of European Equity Trading Venues
In the past few two years we have seen not only increasing liquidity fragmentation in Europe, but a significant change in the pecking order of exchange and venue size. The diagram below lists all venues with a market share of greater than 1% as well as referencing other smaller venues. As can be seen, it shows both the rise of venues, such as Chi-X Europe and BATS, as well as the proliferation of light and dark venues owned by the preexisting exchanges. Chi-X Europe in particular, is now comfortably the largest pan-European venue. There are currently two proposed mergers on the table, firstly between NYSE Euronext and Deutsche Boerse, and the second between Chi-X Europe and BATS.

Exchange Locale
The old model of a country having a primary exchange located within its borders (normally in the main financial district), where its companies’ stocks almost exclusively trade is no longer relevant. As corporate ownership of the manifold liquidity venues becomes more complex and blurred, it is perhaps more meaningful to look at the actual location of the exchange. When we say exchange, we are actually referring not to the administrative or corporate headquarters of the exchange firm, but to the location of the IT infrastructure that runs the actual live exchange matching engine. This location is then a physical data centre building, with an additional failover backup site.
