Mr Bloomberg said Mr Carney will be joined by “the best and brightest”, praising Mr Carney’s work with the company on “climate finance initiatives” and the risk to financial institutions.
Vlad Kliatchko, Bloomberg’s chief product officer, has been promoted to chief executive. A 20-year veteran of the company, Mr Kliatchko studied maths and computer science at St Petersburg University according to his LinkedIn profile.
JP Zammitt, currently chief operating officer, will also become Bloomberg’s president as part of the reshuffle.
Mr Bloomberg said in a memo seen by the Telegraph: “Doing the same thing with the same people in the same way doesn’t work forever.”
The billionaire, who is estimated to be worth more than $90bn, founded his eponymous company in New York in 1981, providing financial data.
It has become best-known for its computer “terminal”, which provides a wide range of financial market data from interest rate bets to bond prices as well as news for investors.
The company generates around $12bn (£9.5bn) a year in revenues, most from its terminals which cost $24,000 a year.
Mr Bloomberg, who is the majority owner of the business, has left the company in the past when he served as Mayor of New York between 2002 and 2013.
He made a failed US presidential bid in 2020, subsequently endorsing Joe Biden.
Bloomberg declined to comment.
