Ortec Finance: The missing middle in portfolio design
By Abdel Brahim, Director, Pension Risk, EMEA and US, Ortec Finance
A practical middle ground between SAA and TPA helps asset owners make better whole-fund decisions without requiring immediate structural change.
Increasingly, conversations about portfolio construction are framed as a choice between two models.
On one side is Strategic Asset Allocation (SAA): stable, transparent and easy to govern. It anchors portfolios to policy weights and benchmarks that support accountability. Yet fixed structures can struggle when markets shift, liquidity tightens or opportunity sets evolve rapidly.
On the other side is the Total Portfolio Approach (TPA): a whole-fund perspective that evaluates every decision through one integrated lens. TPA focuses on overall outcomes rather than on silo benchmarks and encourages alignment with the institution’s objectives and constraints.
In practice, however, few institutions operate at either of these extremes.
Why full TPA is hard to implement
The appeal of TPA is clear. It captures interactions between risks, returns and objectives in a way that siloed thinking cannot. But adopting full TPA in practice requires more than revised beliefs. It often requires changes in governance, better data infrastructure, sharper decision rights, and an organization capable of evaluating decisions at a total-portfolio level. Incentives often need to evolve too. Teams and external managers are assessed less on beating benchmarks and more on their contribution to total-fund outcomes such as liquidity, resilience and alignment with the fund’s risk budget.
For many institutions, such a shift is multi-year and may not always be feasible immediately. The industry often frames the choice as: stay with SAA or attempt a full shift to TPA, even when neither option is realistic.
The missing middle is progress
Meaningful progress is increasingly happening between these two end states. The market uses different labels for this middle ground, but the direction is consistent: funds are moving beyond pure SAA without jumping straight to full TPA.
In this article, I use ‘Total Portfolio Lens’ (TPL) as an umbrella term for this middle ground to keep the discussion practical rather than semantic. The idea is simple: SAA to TPA is a journey. Institutions can adopt whole-fund thinking progressively, based on their maturity, ambition and constraints, rather than treating full TPA as the only destination.
TPL preserves the clarity Boards value, while enabling step-by-step upgrades, including governance guardrails and delegation, without forcing an immediate redesign from day one.
What gets better with a portfolio lens
Once the portfolio is no longer viewed as separate buckets, better decisions emerge. Trade-offs can be evaluated directly against total-fund objectives, including funding strength, liquidity, downside resilience and risk budgets. Liquidity, drawdown behavior and funding dynamics can be analyzed together, rather than scattered across separate workstreams or committees.
Scenario analysis becomes central. Instead of relying on point estimates and stable correlations, institutions can evaluate decisions across different macro paths and stress conditions. For example, increased allocations to private assets can be tested not just for return potential but also for effects on liquidity buffers or funding ratios under market stress. This clarifies which risks truly matter and whether diversification will hold during challenging periods.
Better tools strengthen judgement, not replace it
Recent analytical advances make this evolution far more practical. Scenario‑based optimization can help explore trade‑offs across many economic paths while incorporating multiple objectives. Institutions can also run analyses by regime or focus explicitly on worst‑case scenarios. Structural risks can be integrated in the same workflow, for example climate transition and physical risks, geopolitical fragmentation, and technology-driven productivity shifts.
These tools do not replace judgement. They strengthen it by making trade-offs explicit and revealing interactions between assets, liabilities and cash flows that are often overlooked in more static frameworks.
The questions that matter are whole-fund questions
Asset owners increasingly face questions that cannot be answered through silo analysis:
- How does the portfolio hold up if inflation proves sticky or remains elevated?
- What happens to liquidity buffers in severe stress?
- How do liabilities and cash flows interact with asset behavior in downturns?
- Which decisions build resilience rather than simply improve averages?
These are whole‑fund questions that require whole‑fund tools and perspectives.
A practical path forward
The future of institutional investing will not be shaped only by those adopting full TPA. It will also be shaped by the larger set of asset owners moving beyond static SAA toward integrated, scenario‑aware portfolio design. For many, the missing middle is where real value creation is already taking place with clearer decisions, broader insight and portfolios that better reflect real‑world dynamics.
The debate between SAA and TPA will continue. The more practical question is: How can institutions start making better whole‑fund decisions today, even without a full TPA model? For most, adopting a Total Portfolio Lens provides that path.
