Family office liquidity management for an illiquid portfolio

Family office liquidity management is the practice of matching a portfolio's cash sources to its cash needs when a large share of assets cannot be sold quickly. The surveys agree on the shape of the problem. UBS's Global Family Office Report 2026 found an average cash allocation of 9% against a 42% allocation to alternatives. With private equity distributions running at their weakest level in more than fifteen years, offices need an explicit framework rather than a cash buffer chosen by habit.

How much cash family offices hold

The three largest surveys put cash between 9% and 13% of assets, with the differences explained partly by sample and partly by definition.

UBS's 2026 survey covered 307 offices with an average of $1.3bn under management and recorded private equity at 17% of assets, real estate at 11% and private debt at 3%. Goldman Sachs reported in 2025 that cash excluding US Treasuries stood at 12%, unchanged from 2023, and that 34% of respondents planned to reduce cash and redeploy it into risk assets. Citi's 2025 survey found cash and equivalents at 13%, with private equity at 20% and real estate at 14%. KKR's 2024 survey of more than 75 chief investment officers, published as "Loud and Clear", recorded cash at 9% and alternatives at 52%.

The regional spread is wide. UBS found Asia Pacific offices holding 17% in cash in 2025 and only 13% in private equity, which suggests that the global averages hide very different liquidity positions.

Liquidity tiers

Most offices that manage liquidity deliberately sort assets into tiers by the time needed to turn them into cash without a material discount.

The first tier is operating cash: deposits, money market funds and Treasury bills covering a year or more of family spending, tax and running costs. The second tier is liquid investments, listed equities and investment grade bonds that can be sold within days. The third tier is semi-liquid: hedge funds with quarterly redemption terms, evergreen private funds with gates and direct lending vehicles. The fourth tier is illiquid: closed-end fund interests, direct private holdings and real estate, which can take months to sell and often only at a discount to the last reported value.

The point of the exercise is to set a floor for the first two tiers that holds in a downside case, and to size commitments to the fourth tier so that unfunded obligations can be met from the first three. Forecasting capital calls is the input that makes the floor meaningful.

The 40% problem

An allocation of 40% or more to alternatives changes the nature of liquidity risk. Distributions, which fund both spending and new commitments in a mature programme, stop being reliable. Bain's Global Private Equity Report 2026 found that distributions as a share of net asset value were 14% for the twelve months to the third quarter of 2025, a level last seen in 2008 to 2009, and that the ratio had been below 15% for four consecutive years. Jefferies' Global Secondary Market Review of July 2026 put the annual distribution yield from LP portfolios near 10% in the first half of 2026 against a historical average of 25% since 2001.

The consequence shows up in commitment capacity. Bain reported that 53% of LPs said undrawn commitments were limiting their ability to make new commitments, up 15 percentage points from the end of 2024. An office that assumed distributions would fund calls now has to fund them from cash, from sales of liquid assets or from borrowing. The distributions drought is the single largest change to family office liquidity planning since the global financial crisis.
