What Ostrum Asset Management does
Ostrum Asset Management is a Paris-headquartered European institutional asset manager that manages €388 billion in assets as of March 31, 2026, of which €269 billion is insurance-related. The firm, rebranded in November 2020 from Natixis Asset Management, operates as an affiliate of Natixis Investment Managers within the multi-affiliate structure of Groupe BPCE, France's second-largest banking group. It serves large institutional clients — primarily insurers, pension funds, health insurers, and corporations — through a direct enterprise sales motion and is ranked the 9th largest European institutional asset manager in the IPE Top 500 2025 (as of December 31, 2024).
The platform spans six core capabilities: Investment Solutions, Insurance Solutions & Management, Fixed Income, Equities, Multi-Asset, and Quantitative Management. Fixed Income, the strategic anchor, covers money market, short-term solutions, investment grade credit, crossover credit, high-yield credit, hold-to-maturity, total return bonds, aggregate, emerging bonds, sovereign bonds, inflation-linked bonds, and a 'Just Transition' strategy. The Quantitative Management division runs Minimum Volatility, ESG Focus, Global Macro, Multi-Strategies, Volatility Risk Premium, and Overlay approaches, combining quantitative methods with experienced portfolio management teams. ESG integration is firm-wide: 100% of analyzed assets are run through ESG criteria, 91% of open-ended fund AUM carries the French Label ISR, 70% of open-ended fund assets are rated 4 or 5 stars by Morningstar, and €47 billion sits in green and sustainable bonds. The firm is also a long-standing PRI signatory (since 2008) and has appeared in the RIBI Index for seven consecutive years.
The commercial model is B2B institutional asset management: revenue is generated through management fees as a percentage of customized AUM, billed annually with terms not publicly disclosed. Distribution is direct, via relationship managers targeting large enterprises across 17 country sites spanning Europe, APAC (Hong Kong, Singapore, Taiwan), and Latin America (Chile, Peru). Operational leadership comprises CEO Olivier Houix (appointed December 2023), Global CIO Gaëlle Malléjac (appointed October 2024), CIO Quantitative Management Emmanuel Bourdeix, COO Gaëlle Théaud-Gautheron, Head of Sustainable Transitions Maud Pierre-Minuit (appointed February 2026), Secretary General Vanessa Casano, and Head of Business Development Matthieu Mouly. The investment team totals 125 professionals including 80 portfolio managers, 29 insurance management experts, 9 ESG & CSR strategists, and more than 50 research experts.
