The total portfolio approach (TPA) is attracting growing attention from asset owners, and with it a growing number of questions. Here are the ones we hear most often, answered briefly.
1. What is TPA?
TPA is a holistic way of managing risk and return at the level of the whole portfolio, rather than asset class by asset class. It rests on three principles:
- Goal-driven: portfolio construction stays focused on the fund’s goals.
- Best ideas: every opportunity competes for capital at total-fund level.
- Dynamic: the portfolio responds as markets and goals change.
It is as much a mindset and way of working as a portfolio design.
2. How is TPA different from a strategic asset allocation (SAA)?
An SAA sets a policy benchmark and allocates to asset class portfolios sized to it. TPA starts from the fund’s goals and builds the best portfolio for them. The board sets total risk appetite, typically through a reference portfolio, and the investment team is empowered to act within agreed limits.
3. TPA seems similar to SAA in many respects, why does this need a new programme?
They share some good-practice principles, but TPA differs in important ways: an absolute-return mindset, a reference portfolio to frame risk, a stronger top-of-house function making total-portfolio decisions, and a more integrated “360°” decision and reporting framework. It is less about replacing SAA and more about improving how decisions are made across the whole fund.
4. Is TPA a destination, or a journey?
A journey. TPA is not all-or-nothing. It sits on a spectrum from enhanced SAA through mindset, top-down and joined-up TPA to a fully integrated one-fund model. Not every fund needs to reach the far end to benefit. Each stage can be a waypoint and an appropriate destination in its own right.
5. Is TPA only for large funds?
No. TPA principles can be adapted to funds of different size and sophistication, from a mindset approach to fully delegated models. It has been more common among larger institutions, where scale supports internal teams and systems, but smaller funds with clear governance and nimble teams can also benefit.
6. Does TPA take account of liabilities?
Yes. For funds with liabilities, risk appetite and the reference portfolio should be informed by asset–liability modelling, using consistent assumptions. TPA builds on the liability work and does not replace it.
7. What is a reference portfolio, and does an SAA still play a part?
The most common design has three elements:
- a reference portfolio, a simple mix of passive listed equities and bonds that guides risk appetite;
- a strategic portfolio, similar to an SAA, that guides the favoured top-down allocation at a similar level of risk; and
- an active risk budget that sets how far the total portfolio may deviate from the reference portfolio in pursuit of active return.
Put simply, the reference portfolio is the risk anchor, the SAA is the policy allocation, and the actual portfolio is where skill and decisions live.
8. What happens to asset class teams?
Their role fundamentally remains intact. They still originate and execute investments and add value against their benchmarks. What changes is the framing: they also contribute to total-portfolio outcomes and compete for capital on that basis. In practice that is usually an evolution of existing structures, not a redesign.
9. What does TPA mean for governance?
A clear separation between “setting the problem” and “solving it”. The board owns risk appetite and the reference portfolio, and the investment organisation is empowered to act within explicit limits on stress loss, liquidity and tracking error. Governance is the load-bearing pillar: without clear delegation and trust, the agility TPA needs cannot take root.
10. Where is the evidence that TPA works?
The evidence is directionally supportive but not definitive. In the Thinking Ahead Institute’s 2024 Global Asset Owner Peer Study, TPA adopters showed an average edge of about 1.3% a year over ten years compared with non-TPA peers. The sample was 26 very large asset owners and the comparison is not like-for-like, so it is better read as a signal than a forecast.
11. Where does a TPA transition start, and how long does it take?
There is no single timeline. Transitions are phased and usually start with people and mindset, then move into governance, risk and systems over time. Change of this size often takes longer than planned. Three things help: keep the existing investment model running throughout, secure visible senior leadership from the outset, and show progress through clear milestones and dashboards.
12. What are the main challenges?
Cultural resistance and change fatigue, inconsistent data, managing liquidity as portfolios diversify, and the risk of adding complexity without enough benefit. Advisers should inform the design but not own the decision. TPA is not plug and play, and it will not turn a weak process into a strong one.
