Mercer managed OCIO strategies totaling $393 billion, up 28.5% in the year ended June 30; Aon managed $212 billion, up 16.9% from the prior year; and Willis Towers Watson managed $183 billion, a 23.1% increase.
Willis Towers Watson had worldwide institutional assets under advisement of $3.6 trillion as of June 30, up 38.5% from the prior year.
"OCIO managers definitely are the winners among consulting firms with more progressive strategies, and are outpacing traditional investment consultant firms that don't offer OCIO management," especially when it comes to the impact of higher revenue from OCIO money management, said Kevin P. Quirk, a Stamford, Conn.-based principal at Casey Quirk, a practice of Deloitte Consulting LLP.
The growth of Aon's OCIO practice is "part of a secular trend in the industry as institutional investors, especially corporate defined benefit plans, address their governance and resource issues. In fact, we're seeing a barbell of action with some asset owners opting for OCIO and others developing internal management teams," Mr. Ivinjack said.
The double-digit increase in worldwide institutional AUA as of June 30 revealed in P&I's survey results confirms ongoing demand for investment consulting services.
"I think demand for consultants remains pretty strong. Markets aren't getting any easier and demand for advice continues," Mr. Quirk said.
Because of the growth of assets under advisement, investment consultant revenues should be "pretty good given their asset-based fee model," Mr. Quirk said.
Analysis of average revenue by type as reported by the consultants found that the revenue from investment consulting services for institutional asset owners dropped to 79.2% as of June 30 (prior year, 81.1%); followed by investment outsourcing, 8.3%, (6.6%); other consulting clients, 5.8%, (6.5%); managed funds of funds or separate accounts, 3%, (2.8%); other services, 2.9%, (2.4%); and services provided to money managers, 0.8%, (0.6%).
But even with higher revenues in some areas, "consultants, especially small or under-resourced firms, are starving, especially given the rising cost of essential technology. Merger and acquisition activity will increase and consultants with OCIO capability will be most in demand," Mr. Quirk said.
