Asset Allocation
Last updated 17 July 2026
Asset allocation is the way a portfolio is divided among broad types of investment, such as listed equities, fixed income, private markets, property, real assets, and cash. It turns a family's objectives into a portfolio structure. The decision is usually expressed as target percentages or ranges, with enough flexibility to respond to markets and the family's changing needs.
Allocation is different from security selection. Choosing how much wealth should be exposed to growth assets, defensive assets, illiquid investments, or cash is a portfolio-level decision. Choosing a particular share, bond, or fund happens within that structure. Both matter, but allocation establishes the main pattern of risk, liquidity, and expected return.
Why it matters for family offices
Family wealth is rarely held in one account. It may sit across trusts, companies, custodians, private funds, property, and the operating business that originally created the wealth. An allocation report that covers only liquid portfolios can therefore be badly misleading. The family may appear balanced at one bank while remaining heavily concentrated when direct holdings and underlying fund exposures are included.
The investment policy statement normally records target ranges, liquidity needs, risk limits, and any constraints. Monitoring actual allocation against that policy helps the investment committee see drift before it becomes a deliberate or accidental bet. It also connects investment decisions with capital calls, distributions, taxes, philanthropy, and family spending, all of which affect how much liquidity must remain available.
How it shows up in practice
Suppose a family sets targets of 35 percent public equities, 20 percent fixed income, 25 percent private markets, 10 percent real assets, and 10 percent cash. A strong year for equities, combined with new private fund valuations, moves the actual portfolio to 43 percent equities and 29 percent private markets. The headline cash balance still looks healthy, but upcoming capital calls mean part of it is already spoken for.
The family office brings data from every custodian and entity into one view, adjusts for look-through exposure where information is available, and shows the investment committee the gap from each target range. The committee may rebalance, pause new commitments, or accept the drift temporarily. The important point is that the decision is based on the whole family balance sheet, not a collection of disconnected account reports.
Related terms
Investment Policy Statement (IPS)
A formal document that defines a family's investment objectives, risk tolerance, time horizon, asset allocation targets, and constraints. The IPS guides every investment decision and provides the benchmark against which performance and discipline are judged. It is the anchor document for investment committees and outsourced managers alike.
Rebalancing
The periodic adjustment of a portfolio back to its target asset allocation after market movements cause it to drift. Disciplined rebalancing enforces buying low and selling high and keeps risk aligned with the family's policy. Accurate rebalancing across a multi-custodian, multi-entity portfolio depends on a reliable consolidated view of holdings.
Concentration Risk
The risk that arises when a large share of a family's wealth is tied to a single asset, company, sector, or currency, often the original family business. While concentration frequently created the wealth, it can also destroy it. Measuring true concentration requires looking through all entities and accounts to the underlying exposures.
Liquidity
The ease with which an asset can be converted into cash without significant loss of value. Listed equities and bonds are liquid; private equity, real estate, and collectibles are illiquid. Family offices manage liquidity carefully to fund capital calls, distributions to family members, taxes, and lifestyle spending without forced selling.
Risk Management
The systematic identification, assessment, and mitigation of threats to family wealth and wellbeing, spanning market and liquidity risk, concentration, cyber security, personal safety, reputation, and operational failures. Family offices increasingly formalise risk management with registers, insurance programmes, and controls. Consolidated visibility across all assets and entities is the prerequisite for understanding what is actually at risk.
