Total portfolio approach (TPA) has gained significant attention as asset owners look for better ways to manage increasingly complex portfolios and competing objectives. But the real question is not whether TPA is better than strategic asset allocation (SAA). It is whether a whole-of-portfolio approach can improve the way investment decisions are made.
In Part one of this three-part series, we go back to the origins of TPA to establish what matters before any asset owner changes their portfolio architecture. We explore where TPA came from, why it feels so compelling, what the Australian market is wrestling with and how reference portfolios can help preserve accountability.
At its heart, TPA is first and foremost a governance architecture. Its value does not come from the label, but from making whole-of-portfolio trade-offs explicit, comparable and accountable. Asset owners increasingly need to balance long-term return, peer pressure, regulatory benchmarks, liquidity, costs, ESG and sustainability settings, tail resilience, governance capacity and stakeholder communication. These objectives cannot all be maximised at once, making prioritisation an important part of good governance.
We also consider the role of a Board-owned anchor, whether an SAA, reference portfolio or another clear risk baseline, in creating a hurdle against which active risk, illiquidity, cost and organisational burden can be judged. Complexity must earn its place.
Importantly, adoption is a spectrum and hybrid approaches can be entirely rational. Particularly in Australia, an SAA anchor can coexist with stronger total portfolio decision disciplines without weakening disclosure, oversight or accountability. Ultimately, behaviour is the test. If decision-making remains siloed, adopting TPA language alone does not represent a change in approach.
Part one lands on a simple test: the important question is not whether an asset owner is “TPA” or “SAA”. It is whether its governance model exposes opportunity cost, directs scarce risk and liquidity to their most valuable uses, and preserves clear accountability for the total portfolio. The destination should fit the problem and the standard should always be better decisions.
