The Australian Securities Exchange (ASX) has chosen Tim Whiteley, one of its own employees, to assume the role of Chief Information Officer (CIO), a position that was recently reintroduced.
ASX established the standalone role in March to concentrate on delivering the organization’s enterprise-wide technology renewal program. Whiteley, who was named ASX’s project director in November, will officially take on the role in July. As CIO, he will be responsible for ASX’s enterprise technology functions, technology and data security, data governance, technology infrastructure, and the implementation of its technology modernization program.
Whiteley’s appointment ensures continuity in technology leadership for ASX’s CHESS replacement, a project aimed at replacing the existing system. The recent decision to abandon blockchain and distributed ledger technology as the underlying technology for CHESS was overseen by Whiteley.
Helen Lofthouse, ASX’s Managing Director and CEO, emphasized Whiteley’s expertise in technology and project execution in the financial services industry. She expressed confidence in his ability to lead ASX’s technology modernization efforts and deliver crucial market infrastructure. Whiteley will also be responsible for establishing a new leadership team structure for the CHESS replacement program.
During the search process, Dan Chesterman assumed CIO responsibilities while also delivering technology and data solutions for ASX. Chesterman will continue in his role as Group Executive for Technology and Data, focusing on ASX’s enterprise data capability and the growth of its customer-facing technology and data business.
Lofthouse expressed gratitude to Chesterman for managing two significant executive roles and highlighted that this change will allow him and his team to concentrate on driving innovation in data and technology.
