Overview
BATS Chi-X Europe was a London-based pan-European equity trading venue created through the combination of Chi-X Europe and BATS Europe. It operated primarily as an order-driven market for equities and exchange-traded funds listed on traditional European exchanges, including the London Stock Exchange, Frankfurt Stock Exchange, Euronext markets and OMX venues. Its business model emphasized electronic execution, low latency, competitive pricing and access to a broad set of European securities. The business originated with Chi-X Europe, which was established by Instinet and launched in 2007 in anticipation of the European Union's Markets in Financial Instruments Directive, or MiFID. MiFID opened the European equity-trading environment to alternative venues and helped weaken the historic dominance of incumbent national exchanges. Chi-X Europe was the first pan-European equities multilateral trading facility to launch under this new competitive framework. Its ownership later expanded to include a consortium of financial institutions such as BNP Paribas, Citadel, Citigroup, Credit Suisse, Fortis, GETCO Europe, Goldman Sachs, Merrill Lynch, Morgan Stanley, Optiver, Société Générale and UBS. BATS Europe was established by the United States-based electronic exchange operator BATS Global Markets in 2008 and began operating on 31 October of that year. It developed into one of Europe's largest alternative trading venues, ranking behind Chi-X Europe by 2010. In February 2011, BATS Global Markets agreed to acquire Chi-X Europe for $300 million. The proposed transaction was referred by the UK's Office of Fair Trading to the Competition Commission in June 2011 because of concerns about whether the merger could materially reduce competition. The Competition Commission cleared the transaction in November 2011, and the acquisition closed on 30 November 2011; some accounts identify the operational acquisition as completing on 1 December. The combined venue was led by Mark Hemsley, formerly chief executive of BATS Europe. It brought together trading in approximately 1,800 securities across 25 indices and 15 European countries. The two technology platforms were integrated by April 2012, after which Chi-X Europe customers were migrated to the BATS Europe platform. During the period after the combination, BATS Chi-X Europe was frequently the largest pan-European cash-equities venue by value traded. Its reported market share exceeded 25% in December 2011 and was approximately 24.6% in April 2012. The venue initially operated as a multilateral trading facility under the supervision of the UK's Financial Services Authority and subsequently the Financial Conduct Authority. In May 2013 it received Recognised Investment Exchange status from the FCA. This enabled it to operate a regulated market for primary listings in addition to its existing secondary-market trading activities. The company also participated in European market infrastructure initiatives, including the planned consolidation of major cash-equities clearing operations. In 2013 it announced that it would take a 25% stake in EuroCCP, the clearing house that emerged from the proposed combination of Europe's leading cash-equities clearing providers. BATS Chi-X Europe later introduced investor-facing market-data initiatives, including a free UK index series announced in 2016. The series included the Bats UK 100, positioned as an alternative to established UK equity benchmarks and made available with real-time information to private and retail investors. The BATS Chi-X Europe name was subsequently superseded as the European business became part of Cboe's European market infrastructure following Cboe Holdings' acquisition of BATS Global Markets in 2017. The historical brand is therefore treated as defunct, although much of its trading operation continued under successor Cboe Europe businesses.
History
BATS Chi-X Europe emerged from two independent electronic trading venues created during the liberalization of European equity markets. Chi-X Europe was founded by Instinet and launched in 2007, ahead of the implementation of MiFID's competitive framework. It was designed as a pan-European multilateral trading facility, allowing market participants to trade securities listed on incumbent exchanges while competing on execution speed, operating costs and access. Chi-X Europe's ownership eventually broadened to include a group of major financial institutions. The venue gained substantial market share, particularly in liquid UK equities, and became one of the principal challengers to the London Stock Exchange and other national exchanges. Its growth continued despite management changes: Peter Randall left the chief executive role in 2009, and Alasdair Haynes became chief executive later that year. Chief operating officer Hirander Misra left in 2010. The business introduced additional trading functionality, including the Chi-Delta dark book in 2009, and reported several profitable quarters by the middle of 2010. BATS Europe was established by BATS Global Markets in 2008. Mark Hemsley was appointed chief executive and Paul O'Donnell chief operating officer, and the venue commenced operations on 31 October 2008. By 2010, BATS Europe had become the second-largest multilateral trading facility in Europe behind Chi-X Europe. BATS Global Markets subsequently agreed in February 2011 to acquire Chi-X Europe for $300 million. The proposed transaction underwent UK competition review. The Office of Fair Trading referred it to the Competition Commission in June 2011 to examine whether the merger might substantially lessen competition. The Competition Commission approved the transaction in late November, and BATS closed the acquisition on 30 November 2011. The combined enterprise adopted the BATS Chi-X Europe identity and was led by Mark Hemsley. The consolidated venue covered approximately 1,800 stocks across 25 indices and 15 European countries in early 2012. It recorded more than one-quarter of pan-European equity trading in December 2011 and approximately 24.6% in April 2012, according to the historical account of the business. The technology integration was completed by April 2012, when Chi-X customers were migrated to the BATS Europe platform. The venue's regulatory position also developed. It operated as an FCA-authorized multilateral trading facility under the MiFID framework and was subject to supervision intended to reflect the significance of large alternative venues. In May 2013, the FCA granted Recognised Investment Exchange status. This allowed BATS Chi-X Europe to operate a regulated market supporting primary listings as well as its existing secondary-market activities. BATS Chi-X Europe also became involved in market infrastructure beyond trading. In March 2013, it announced that it would take a 25% stake in EuroCCP, a clearing business associated with the planned combination of two major European cash-equities clearing providers. In 2016, it announced a free UK index series with real-time information for private and retail investors, including the Bats UK 100. The brand's independent existence ended after Cboe Holdings acquired BATS Global Markets in 2017. The European operations were subsequently incorporated into Cboe's European businesses and the BATS Chi-X Europe name ceased to be the principal operating brand. Its legacy is the expansion of competition in European equity trading, the normalization of pan-European electronic execution and the development of alternative-market infrastructure alongside traditional exchanges.
