Michael Spencer: Early Life and Education
Michael Spencer was born on 30 May 1955 in Kuala Lumpur, then part of British Malaya. His father was an economist and civil servant, while his mother was a linguist, shaping a household of intellect and curiosity. Growing up across countries like Sudan and Ethiopia due to his father’s work, Spencer gained an early understanding of international culture and economics.
At just eight years old, he was sent to England to study at Worth School in Sussex. His academic potential was clear from a young age. He later earned a place at Corpus Christi College, Oxford, where he studied Physics. Although science was his chosen discipline, Spencer’s fascination with markets and risk-taking hinted at the remarkable path his career would soon take.
Rise of a Financial Lord: The Beginning of a Legacy
After graduating from Oxford, Michael Spencer began his career in 1976 with the London brokerage Simon & Coates. His sharp intellect and entrepreneurial drive quickly set him apart. By 1981, he had advanced to Drexel Burnham Lambert, one of the most powerful investment banks at the time.
In 1986, Spencer took the boldest step of his career — he co-founded Intercapital Brokers, which later became ICAP plc. His leadership transformed the firm into the world’s largest interdealer broker. ICAP revolutionized the trading world by introducing electronic platforms that replaced traditional voice-based systems, bringing speed, transparency, and efficiency to financial markets.
Business Empire and Expansion: ICAP to NEX Group
Under Spencer’s visionary direction, ICAP grew from a small start-up to a global financial powerhouse listed on the London Stock Exchange and included in the FTSE 100 index. Its dominance in global bond, currency, and commodities trading was unmatched.
In 2016, Spencer orchestrated a strategic move by selling ICAP’s voice broking business to Tullett Prebon, rebranding the remaining operations as NEX Group. This shift marked his foresight into the digital age of trading. NEX Group focused on electronic markets and post-trade technology, cementing Spencer’s reputation as a pioneer in financial technology.
Two years later, in 2018, CME Group acquired NEX Group for £3.8 billion. The acquisition not only rewarded Spencer with vast financial success but also positioned him as one of the most respected business leaders in London’s financial elite.

In recognition of his immense contribution to business and philanthropy, Michael Spencer was granted a life peerage in September 2020, becoming Lord Spencer of Alresford. This honor symbolized his influence beyond commerce — into public policy, economics, and charity.
As a Lord, he continues to contribute insights into financial governance and trade policy, representing the ideals of responsible capitalism. Through his private investment firm, IPGL Group, Lord Spencer invests in cutting-edge fintech, energy, and technology ventures. His portfolio includes major stakes in companies such as Klarna, AJ Bell, and Nutmeg, demonstrating his belief in innovation-driven finance.

In 1993, he founded ICAP Charity Day, an annual event where the day’s trading revenues are donated to global charities. The initiative has raised more than £170 million, supporting thousands of causes worldwide.
Spencer’s compassion extends to environmental and conservation causes. Through the Borana Conservation Trust in Kenya, he has helped protect endangered species, including black rhinos. His efforts exemplify how wealth, when combined with purpose, can bring lasting change to both people and the planet.

However, his journey also faced scrutiny, particularly during the 2013 LIBOR investigation involving ICAP. Although Spencer was not personally charged, the incident tested his reputation.
