December 17, 2019

United States, New York


Mercer today announced its global assets under management had reached $304.5 billion USD1 as of 30 November, 2019.


In June 2019, Mercer was ranked first by worldwide, outsourced assets under management by Pensions & Investments2.  Mercer was also ranked first in Outsourced Chief Investment Officer (OCIO) by global assets under management by CIO magazine, as of December 20183.  Pensions & Investments also named Mercer first by global assets under advisement (AUA) as of June 30, 20194.


“We are seeing Mercer’s value proposition resonating with the market. Mercer continues to provide investment fiduciaries and other institutional investors with advice on objective setting and strategy. We can also offer flexibility in implementation models, including digital delivery of our manager research, traditional investment consulting advice, and OCIO investment solutions. We believe the ability to provide customized strategic advice with flexibility of implementation models is driving our growth,” said Rich Nuzum, CFA, global President of Mercer’s Wealth business.  


“Besides our growth in OCIO AUM, we’ve also experienced strong growth in interest for our manager research through MercerInsight, our digital delivery platform, and in our traditional investment consulting client base. As of June 2019, over half of Mercer’s $15 trillion in assets under advisement were from MercerInsight clients that have access to the firm’s manager research5,” said Deb Clarke, Mercer’s Global Director of Research.


She continued: “The market has taken particular notice of our strength in research on alternative asset classes. Many investors are working to improve their diversification by adding to alternative asset class exposures as the stock market reaches new highs and bond yields carry on trading near historical lows.”


Mercer’s clients include many types of institutional investors, such as defined benefit and defined contribution plans, insurance assets, financial intermediaries, not-for-profit foundations, endowments and healthcare systems, family offices and sovereign wealth funds.


1 In providing OCIO services, Mercer typically exercises investment discretion by hiring and overseeing third party asset managers on behalf of client portfolios. Global OCIO assets data is primarily but not exclusively discretionary mandates.




Pension & Investments and CIO magazine rankings are based on survey responses from responding firms. Mercer may calculate worldwide assets under advisement and worldwide assets under management differently than other responding firms.

5 Most of these MercerInsight clients are also traditional investment consulting clients.
