The move represents the first major cut in Spencer’s biggest asset after CME acquired NEX in 2018 in a deal that valued the electronic trading platform at 3.9 billion pounds ($5.4 billion).
The 66-year-old former Conservative Party treasurer originally made his fortune through ICAP Plc, NEX’s predecessor company, a business he founded in 1986. The firm grew to become the world’s biggest broker of deals between banks and turned Spencer into one of the City of London’s most prominent figures.
Spencer has diversified his fortune into real estate, wine and wealth management through London-based IPGL. It had 1.1 billion pounds in net assets at the end of March 2021 and received more than 150 million pounds from disposals in that fiscal year, the filing showed.
Spencer also recently obtained a loan from Credit Suisse Group AG through his family office to acquire one of Bombardier Inc.’s Global 5500 private jets, typically available for about $45 million.
Since completing the NEX purchase, CME’s shares have increased about 20% through Thursday.
