Hamza Lemssouguer: The Moroccan Worth $20 Billion

Originally from a modest background in Casablanca, the son of a port employee and a teacher, he followed an excellent academic path up to the École Polytechnique before joining the City. After declining a multi-billion dollar offer from Citadel in 2020, he launched Arini Capital in 2022. According to the Wall Street Journal, the 35-year-old trader now oversees $20 billion. He is considered the fastest-growing hedge fund manager of his generation.

Arini Capital has specialized in European credit and distressed debt, benefiting from a high interest rate environment in 2025 and 2026. The fund intervenes with over-indebted companies where traditional banks are withdrawing. With an average annual return of 15%, double the benchmark index, Lemssouguer’s strategy is based on in-depth sectoral research. To respond to criticism about the use of financial leverage, he has developed a "risk reduction engine" after initial losses recorded in 2022.

An atypical figure in London finance, Hamza Lemssouguer does not drink and does not drive. He acquired his American accent by watching TV series and lives in a Tudor-style estate where he raises 160 rare parrots. His personal success coincides with the ambitions of the Casablanca Finance City, which is positioning itself as a financial bridge between Africa, Europe and the Mediterranean. The journey of this gifted mathematician illustrates the growing role of talents from the Moroccan diaspora in global capital flows.

His rise underscores the importance of new credit routes and customized financing in a European economy under pressure.
