The biggest risk in adopting a total portfolio approach is not the framework itself but complexity without clear accountability, according to a research paper released by Frontier Advisors on 3 November 2026.
The paper, the first in a three-part series, examines the origins and appeal of total portfolio approach (TPA) thinking and its implications for Australian institutional investors. It argues that many institutions may be better served by a hybrid model that retains a Board-approved strategic asset allocation (SAA) anchor while strengthening whole-of-portfolio decision-making.
Frontier notes that TPA is widely discussed but not always clearly understood. Audience polling at the firm’s 2026 client conference found that 43 per cent of respondents associated TPA with a pure competition-for-capital model, 27 per cent saw risk as its key anchor, and 30 per cent were unsure what the term meant.
When asked about the biggest risk of moving to TPA, 25 per cent selected a mismatch with existing governance, policy or delegations, while 24 per cent selected blurred accountability, attribution and decision rights.
Paul Newfield, Frontier Advisors Director of Specialist Services and author of the series, said the debate needed to move beyond investment terminology.
“The danger is not SAA versus TPA. It is complexity without accountability,” Newfield said. “Asset-class allocations tell a Board where capital sits, but they do not always reveal the economic risks building up across the portfolio, how those risks interact or where liquidity will come from under stress.”
Good governance is not a promise that every measure will be green at every meeting. It is agreement about what matters most, which constraints cannot be breached and which compromises are acceptable. TPA does not remove those difficult choices. However, it should make them more transparent.

The paper identifies “objective overload” as a central governance challenge. Asset owners must balance returns, downside resilience, liquidity, fees, regulatory benchmarks, peer comparisons and sustainability commitments. These objectives cannot all be maximised at once.
Newfield argued that good governance requires explicit agreement on what matters most, which constraints cannot be breached, and which compromises are acceptable. TPA does not remove those choices, but it should make them more transparent.
A central recommendation is the use of a reference portfolio: a simple, low-cost expression of the Board’s risk appetite against which a more complex actual portfolio can be assessed. Private assets, active strategies and overlays should demonstrate their value after allowing for costs, illiquidity, risk and the governance burden they create.
For Australian investors, Frontier suggests that regulatory requirements, disclosure obligations, peer comparisons and stakeholder communication can make retention of an SAA anchor sensible, while total-portfolio thinking is used to improve risk budgeting, liquidity management and investment choices.
“A hybrid is not necessarily a compromise on quality. It can be the right design for the institution,” Newfield said. “The destination should fit the problem. The standard should always be better decisions, with clear accountability for the total portfolio.”
