President, Europe, at CBOE Holdings
Mark Hemsley is president, Europe, at CBOE Holdings, joining the firm in 2017 as part of the Bats Global Markets acquisition. Based in London, he leads a team of approximately 70 people, operating the largest pan-European stock market and trade reporting facility.
A founding employee of Bats Europe in 2008, Hemsley is a well-respected industry expert and leader whose team has played a major role in transforming Europe’s equity markets over the past decade. In 2011, Hemsley led the transformative acquisition and integration of Chi-X Europe, creating the leading stock exchange group in Europe and surpassing legacy markets that had been in operation for hundreds of years.
Under Hemsley’s leadership, Bats became a Recognized Investment Exchange (RIE) in 2013, and in August 2016, Bats Europe announced plans to launch Bats LIS, powered by BIDS Trading, a new block equity trading platform for Europe’s equities market. It has also launched new benchmark real-time indices for numerous major European markets.
Before joining Bats, Hemsley was managing director and chief information officer at LIFFE, running its Market Solutions group. At LIFFE, from 2001 to 2004, he won major contracts with top exchanges and transformed the technology organisation to capture greater revenue from its exchange businesses. A LIFFE board member, he was also heavily involved in the sale of the company to Euronext.
He also served as chief operating officer and chief information officer during his tenure at Deutsche Bank GCI, the investment bank where he managed teams of professionals in Frankfurt, London, New York, Singapore, Sydney and Tokyo while working closely with the firm's trading operations.
His previous positions include vice president at Credit Suisse First Boston, where he was global head of foreign exchange technology, and a stint as CIO at Natwest Capital Markets.
