Liquidity is often treated as idle money — a drag on returns to be minimised. We think of it differently: as the asset that protects every other asset.
Of all the questions we ask new clients, one of the most revealing is also the simplest: if you needed a significant sum in ninety days, where would it come from?
The answer matters because illiquidity is rarely a problem until it is suddenly the only problem. Portfolios are compromised not by bad assets but by good assets sold at bad moments — the investment liquidated in a down market to fund a tax bill, a property closing, or a family need that could not wait for prices to recover.
Liquidity planning is the discipline of making sure that never has to happen. It begins with an honest map of upcoming commitments: known obligations, likely ones, and the merely possible. Against that map we hold reserves in tiers — immediate funds for the near term, high-quality liquid investments behind them, and only then the long-term capital that should never be interrupted.
Viewed this way, the cash and short-term holdings in a portfolio are not idle. They are doing one of the most valuable jobs in the entire plan: buying the rest of the portfolio the time it needs to work. The modest return given up is the premium on that insurance, and in our judgement it is usually the cheapest insurance a family owns.
The right amount of liquidity differs for every family — it depends on spending, obligations, income stability and temperament. But the principle does not: the long-term investor's greatest advantage is never being forced to act, and liquidity is what preserves it.
