Strategic Asset Allocation for Family Offices
UHNW asset allocation is not just institutional allocation at smaller scale. The constraints, time horizons, and risk profile differ enough to require their own model.
Key takeaways
- —Tax drag is the single largest unmodelled cost in standard allocation frameworks.
- —Concentrated single-stock or operating-business positions distort the rest of the portfolio.
- —Generational horizon allows higher illiquidity tolerance than institutional benchmarks suggest.
- —Liquidity ladders matter more than total liquidity figures.
Institutional asset allocation models — the Yale model, the all-weather model — are useful starting points for UHNW families, not destinations. The differences are real. Most families pay tax that institutions do not, hold concentrated positions that institutions would never accept, and have time horizons that span generations rather than funding cycles. Each of those facts pulls the allocation away from institutional norms.
What works in practice is a custom strategic allocation that explicitly incorporates the family's tax profile, the concentrated-position overlay, the generational horizon, and a structured liquidity ladder. The ladder — what is liquid this year, what is liquid in 1-3 years, what is genuinely long-term — turns out to be more useful than headline cash percentages. Once the ladder is set, the rest of the allocation falls out of it more cleanly than from any external benchmark.
