Some people like to say that "cash is for those who don't know what to do with their money." It sounds like the microwave wisdom of the average aggressive investor. In reality it is, at best, a half-truth — and half-truths in finance usually cost more than complete lies.
It is true that cash, sitting still and forgotten, loses purchasing power every year. Holding your entire net worth in a savings account is a mistake. But between "everything in cash" and "nothing in cash" there is a universe of nuance. Because cash, used with intention, is not financial laziness: it is the capacity to respond.
I have written before about liquidity risk — the danger of being trapped in assets you cannot sell when you need to. Today I want to look at the other side of the coin: liquidity not only as a risk you have to manage, but as a strategy you can use in your favor.
Being invested is not the same as being trapped
Let's start by separating the two. Being invested means your capital is working in assets you chose, with a clear thesis and the ability to exit when you decide to. Being trapped means your capital sits in assets you cannot move without destroying their value, precisely when you would most need to move them.
The difference does not show up on the good days. It shows up when an emergency arrives, or an opportunity that will not repeat itself, or a change of plans. That is when you find out whether you built a portfolio or an elegant trap.
The market can stay irrational longer than you can stay solvent. Plenty of people are right in their analysis and still lose — not because they were wrong, but because they ran out of air, out of liquidity, before the market proved them right.
Why this matters more when you invest across a border
If you are investing from Canada or anywhere outside the United States, this question gets sharper, not softer. Cross-border moves add steps that are hard to schedule: opening accounts, funding them, transferring capital between currencies and institutions, closing on a property, capitalizing a company, waiting on professional reviews. Each step has its own timing, and the timing is rarely yours to control.
None of that is a reason to be afraid. It is a reason to plan your liquidity as deliberately as you plan your investments. An investor who has to sell something good in order to fund something else — at whatever price the market offers that week — is paying an avoidable cost. This is educational context, not legal, tax, or immigration advice; the specifics of any structure should be reviewed with qualified professionals in both countries.
Cash as the capacity to respond
Keynes himself called it "liquidity preference": the willingness to keep money available not out of fear, but because of the value of being able to act. Holding cash is, deep down, buying an option. The option to say yes when something worthwhile appears, and the option to say no to selling something good at the worst possible moment.
Whoever has no liquidity is forced to react. Whoever has it gets to choose. And in finance, the difference between reacting and choosing is almost always the difference between losing and winning.
Liquidity for opportunities you have studied, not for improvising
Holding cash "just in case," without knowing what you would do with it, is not a strategy: it is indecision dressed up as prudence. Strategic liquidity only makes sense if it is connected to opportunities you have already studied.
Seth Klarman argues that cash is not a bet on the market, but the natural residue of not finding opportunities that meet your criteria. In other words, you do not accumulate cash because "you think it will go down," but because you have a list of things you would buy at a certain price, and while that price does not arrive, you wait. Cash stops being passivity and becomes patience with a thesis behind it.
Improvisation is the opposite. It is having money available and, at the first trend that comes along, jumping in without analysis just because "something had to be done with it." That is not strategic liquidity; it is liquidity in a hurry, and hurry is expensive.
The cost of holding freedom
None of this is free, and it would be dishonest to pretend otherwise. Holding liquidity has a real cost: inflation. Every dollar you keep available buys a little less next year. That is the central tension of the topic — protecting yourself from inflation pushes you to invest everything, while preserving room to maneuver pushes you to hold. Both are reasonable, and they contradict each other.
The way to think about it is that the loss inflation causes on a reasonable liquidity reserve is the price you pay for an extremely valuable option. It is like an insurance premium. Nobody complains about "losing" the money spent on home insurance when the house did not burn down. Liquidity is the insurance that lets you avoid dumping your assets in a crisis and, at the same time, take advantage of the opportunities that same crisis creates for those who have something to buy with.
The mistake is not holding liquidity. The mistake is not knowing how much, or what for
Financial maturity does not consist of always being fully invested, as if leaving money available were a sin. It consists of understanding that the capacity to act has a value of its own, sometimes greater than the return you give up to preserve it. The investor who is always fully invested feels productive, but has given up freedom to maneuver without noticing.
So, in your case: is your cash reserve financial laziness waiting for an excuse, or a strategy waiting for its moment?
