The FCA has made two permanent appointments to its executive team.
Johan Sekora will join the FCA as Chief Operating Officer next month and will relocate from Stockholm.
Simon Walls has accepted a permanent role as executive director for the market after carrying out the same duties on a temporary basis since 2024.
Sekora joins from Swedish bank SEB, where he was global head of financial crime prevention.
He has 25 years of experience in the financial services industry, including 20 years at HSBC, and has liaised with the Swedish police to combat crime.
The FCA says he is a leading voice in using data and artificial intelligence to tackle emerging risks.
Walls spent 20 years at the municipal regulator and has held leadership positions in wholesale markets, including policy, asset management and banking supervision.
The FCA says it has played a key role in navigating key events impacting markets, including the Libor transition and Britain’s departure from the EU.
Sekora says: “As the leading and largest European regulator, the FCA is leading the way in many regulated areas by protecting customers, driving smarter regulation and fighting financial crime through collaboration and the use of AI.”
Walls says: “The UK financial markets have been defined by innovation, openness and integrity for centuries.
“I am delighted to lead such a dedicated and professional team at the FCA as we deliver our ambitious market work to continue these traditions.”
FCA chief executive Nikhil Rathi said: “A strong leadership team is critical to being the smarter regulator we want to be.
“Simon’s appointment provides continuity as we continue to transform our wholesale markets, while Johan brings significant international experience that will help us operate more efficiently and effectively in the interests of consumers, markets and the wider economy.”
