Canadian plans like HOOPP and CPPIB lead the shift, but culture stalls most transitions
Just eight of the world's 100 largest asset owner funds have fully adopted the total portfolio approach, even as the method reached what its proponents call a tipping point in institutional investing.
That count comes from a July 2026 CFA Institute report, drawing on Thinking Ahead Institute data, which found that 66 of the top 100 funds still organize around strategic asset allocation and 26 run hybrid models.
TPA is far less common among smaller funds, the report notes, though it says the framework "crossed the chasm" from early adopters to mainstream acceptance in 2025.
For pension plans, the shift is not abstract.
Canadian funds sit among the early movers.
The report identifies HOOPP as an asset owner transitioning to TPA, while CPPIB and PSP Investments are cited for collaborative cultures that have supported their models, having broken down silos between asset-class teams, investment management, and risk management.
Canada, alongside Australia and New Zealand, hosted some of the first adopters when the approach emerged between 2000 and 2009.
The report, written by Roger Urwin of WTW and Genevieve Hayman of CFA Institute, frames TPA as an evolution of strategic asset allocation rather than a break from it.
Under SAA, boards set long-term benchmarks and asset-class teams execute within defined buckets.
TPA instead evaluates each investment by its contribution to total fund objectives and treats capital market assumptions as dynamic rather than fixed.
The authors argue benchmarks can drift into becoming ends in themselves, and that splitting benchmark design from portfolio construction leads teams to optimize locally rather than collectively.
On performance, the evidence remains thin.
Over half of survey respondents estimated risk-adjusted return benefits of more than 50 bps compared with an SAA counterfactual.
It also points to a working paper by Garmash that found TPA adopters earned an average of 150 bps of additional return annually over 10 years relative to SAA peers, and to a Thinking Ahead Institute study of 26 funds where adopters outperformed by 1.3 percent per year.
The authors caution, however, that fund-size differences, short track records, and the small pool of adopters make firm comparisons difficult.
The findings rest on interviews with 14 senior executives from 11 organizations, representing funds with roughly US$1.4tn in assets and managers overseeing more than US$1.48tn.
The report's central practical message is that the hardest parts of a transition are organizational, not technical.
The most commonly cited barriers were cultural change, team coordination, and governance rather than investment methodology.
That theme runs through the interviews.
"You need to have a culture where people want to work together. Silos exist for a reason. Most people like working in a silo. It's easier to do things tribally," said Johanna Kyrklund of Schroders.
Stephen Gilmore of CalPERS put a figure on expectations, warning boards to be realistic that raised performance "might be, perhaps 50-60 basis points."
According to Jacky Lee of HOOPP, the approach does not demand constant activity. "TPA doesn't mean you have to act all the time.
Sometimes it means doing nothing, because you're watching the market every day and choosing not to act.
Indecision is a decision itself," Lee said.
The report treats TPA as a spectrum rather than a switch, describing five levels from enhanced SAA to full one-fund integration, and says partial adoption can still deliver benefits.
It recommends funds begin with belief setting, a governance review, or a reference portfolio design exercise.
Even so, the authors expect SAA to remain the dominant system for the foreseeable future, arguing the constraint on adoption is the depth of a fund's organizational resources rather than its size.
