Jonathan Lourie is a British-American financier best known as the founder, Chief Executive Officer and Chief Investment Officer of Cheyne Capital, the London-based alternative investment manager he established with Stuart Fiertz. His professional career spans more than four decades, beginning at Morgan Stanley and later moving into independent asset management.
Unlike many wealthy financial executives, Jonathan Lourie has maintained a relatively private public profile. Much of the reliable information about him comes from Cheyne Capital’s corporate biography, business records and established news coverage rather than extensive personal interviews.
This article examines Jonathan Lourie‘s education, early career, role at Morgan Stanley, the creation and development of Cheyne Capital, publicly reported family information and the question of his personal wealth. Where figures are estimates rather than verified disclosures, that distinction is made clear.

Who Is Jonathan Lourie?
Jonathan Lourie is an investment executive who has spent most of his career working in alternative asset management and credit markets. He is particularly associated with Cheyne Capital, where he has served as founder, CEO and CIO since the firm’s launch.
Cheyne Capital says Jonathan Lourie and Stuart Fiertz founded the business in 2000. The firm describes its investment expertise as covering real estate debt, social-property impact strategies, investment-grade corporate credit, stressed and distressed credit, and equity-linked investing.
The connection with Morgan Stanley is important to understanding his career. Before establishing Cheyne Capital, Lourie worked at Morgan Stanley from 1985 and helped build its convertible-bond management practice.
Early Life and Education
Public information about Jonathan Lourie‘s childhood is limited, but his educational history is unusually well documented through Cheyne Capital.
According to the firm’s official biography, he attended the International School of Geneva from 1967 to 1979. He subsequently studied at Dartmouth College in Hanover, New Hampshire, from 1979 to 1983. He graduated from Dartmouth in 1983 with Phi Beta Kappa and Summa Cum Laude distinctions.
His education also helps explain the international nature of his later career. After completing university in the United States, he entered the financial industry and eventually built his professional base in London.
Verified public information about his parents, childhood home, or other family circumstances is much less. Those gaps are preferable to filling the biography with unverified claims.
Morgan Stanley Career Before Cheyne Capital
Before Jonathan Lourie became associated with Cheyne Capital, Morgan Stanley played a major role in his professional development.
He joined Morgan Stanley in 1985 and worked in a convertible-bond-related area. Cheyne Capital’s official biography credits him with creating and developing Morgan Stanley’s convertible-bond management practice.
Convertible bonds combine characteristics of debt and equity, making expertise in the area particularly relevant to someone who would later work across different parts of the capital structure. His Morgan Stanley experience therefore provides useful context for the investment strategies associated with his later career.
Lourie remained at Morgan Stanley until the creation of Cheyne Capital in 2000. His co-founder, Stuart Fiertz, also worked at Morgan Stanley, where he worked on customized portfolio strategies and credit research.
Jonathan Lourie and Cheyne Capital
The most important chapter of Jonathan Lourie‘s career began when he and Stuart Fiertz founded Cheyne Capital in 2000.
The company has since developed into a London-based alternative investment manager with expertise spanning corporate and real estate markets. Cheyne’s current corporate profile identifies Jonathan Lourie as Founder, CEO, and CIO, while Fiertz serves as Co-Founder and President.
| Career stage | Key detail |
|---|---|
| 1967–1979 | Attended International School of Geneva |
| 1979–1983 | Studied at Dartmouth College |
| 1983 | Graduated Phi Beta Kappa and Summa Cum Laude |
| 1985 | Began career at Morgan Stanley |
| 1985–2000 | Developed experience in convertible-bond management |
| 2000 | Founded Cheyne Capital with Stuart Fiertz |
| 2000–present | Leadership role at Cheyne Capital |
Cheyne’s investment activities have evolved. The firm’s current website identifies real estate debt, social property impact, investment-grade corporate credit, stressed and distressed credit, and equity-linked investing among its principal areas of expertise.
That breadth matters because it means his career cannot be reduced to the label of “hedge-fund manager”. His work has spanned several areas of alternative investment and capital markets.
Jonathan Lourie Family and Personal Life
Public reporting has linked Jonathan Lourie to former model Frida Andersson, who was previously married to Lourie before later marrying former England footballer Jamie Redknapp.
The Evening Standard reported in 2021 that Andersson was previously married to hedge-fund manager Jonathan Lourie and that they had four children together. The publication did not provide extensive information about the children, and their privacy has generally been maintained.
This is one area where online biographies sometimes go beyond the available evidence. Claims about private relationships, family arrangements, or a current partner should not automatically be treated as confirmed unless supported by reliable reporting.
No strong current primary-source evidence establishes a new relationship for Jonathan Lourie. His public professional profile remains much more prominent than his personal life.
Jonathan Lourie Net Worth: What Is Actually Known?
The question of Jonathan Lourie‘s net worth is harder to answer with precision than his career history.
Cheyne Capital has not released any current official personal wealth disclosure to establish a definitive figure. Several websites publish estimates, but they disagree substantially and often provide little evidence for the numbers they quote.
Some secondary biographies cite an approximate £80 million figure linked to a 2013 Sunday Times Rich List reference. However, this is historical information rather than a verified measurement of his wealth in 2026.
Other websites now claim much higher figures, including estimates above £500 million, but no comparable authoritative wealth disclosure supports these numbers.
Consequently, the most responsible description is that Jonathan Lourie is a highly successful investment executive whose personal net worth has not been publicly verified at a current figure.
Cheyne Capital’s scale should also not be confused with his personal wealth. Assets managed by an investment firm belong to its funds and clients; they are not automatically the firm’s founder’s personal assets.
Current Role and Professional Profile
As of 2026, Cheyne Capital still lists Jonathan Lourie as Founder, CEO, and CIO. The firm’s official website still identifies him as a member of its executive leadership.
His long tenure is unusual in an industry where senior investment professionals frequently change firms or launch new ventures. Instead, his career has remained closely connected to the organization he co-founded.
A 2023 Cheyne regulatory disclosure also listed Lourie among members of the firm’s Executive Committee, with senior management functions relating to overall management and oversight.
For readers researching Jonathan Lourie, the clearest picture is therefore one of a private financial executive whose public identity is closely tied to Cheyne Capital rather than celebrity culture.
Conclusion
Jonathan Lourie has built a long career in investment management, moving from Morgan Stanley’s convertible-bond business to co-founding Cheyne Capital with Stuart Fiertz in 2000. His education at the International School of Geneva and Dartmouth College preceded a professional career that has remained focused on financial markets and alternative investments.
The available evidence is strongest on his professional history and current position. His personal wealth is less certain. Although websites publish various estimates, no current authoritative disclosure establishes an exact figure for Jonathan Lourie‘s net worth. The same caution applies to some details of his private life.
For readers researching Jonathan Lourie, the central fact is straightforward: he is the long-serving founder, CEO and CIO of Cheyne Capital, and his professional influence is primarily reflected through the investment firm he helped build.
