Holding too much cash costs a company money. Holding too little can put its ability to pay at risk. So how much should a treasury keep? It's one of the central questions in managing liquidity.
At first glance the answer looks simple: keep enough for upcoming payments and invest the rest. Reality is more complicated. Collections don't always arrive on the expected date, some payments come forward and certain funds carry restrictions that keep them from being used right away.
That's why deciding how much cash to hold isn't about setting a percentage of revenue or a fixed amount in the accounts. It's about understanding how much money is needed, when it's needed and how much uncertainty surrounds those needs.
1. What minimum cash is
Minimum cash, which FLIQO calls the minimum available reserve, is the level of liquid funds an organization considers necessary to keep in order to run its operations and meet its obligations under certain conditions. Its purpose is to reduce the risk of running into payment problems for lack of immediate availability. It's the part of available cash that isn't committed, as explained in how treasury manages a company's liquidity.
There's no universal figure that fits every company. One that collects every day and has steady payments needs something very different from one whose collections bunch up on certain days of the month. Its business, the volatility of its revenue, its payment structure, restrictions on funds and alternative sources of financing all play a part.
That's why minimum cash has to reflect each organization's own characteristics.
2. Why holding too much cash is costly
Available cash brings flexibility and security: it lets you pay, seize opportunities and respond to the unexpected. But keeping excess funds in low-yield accounts has an opportunity cost.
Picture a company that routinely holds 20,000 million in cash, even though its operations and contingencies justify a much smaller amount. The difference could go, under its investment policy, into instruments that earn a return without compromising future availability.
That doesn't mean every surplus should be invested immediately. The decision has to weigh the safety of the funds, the terms, counterparty risk and expected needs. Nor is the goal to maximize return at any cost: it's to put funds to good use without compromising the ability to pay.
3. What happens when a company holds too little liquidity
The opposite problem can be even more serious. An organization with balances that are too tight may need emergency financing when collections run late or an unexpected obligation appears. That brings extra financing costs, investments sold early or trouble meeting commitments, and it can rule out opportunities that require cash on hand.
That's why a treasury shouldn't aim for the lowest possible bank balance, but for a level of liquidity that fits operating needs and the risk the organization is willing to take.
4. How to work out how much cash a company needs
Setting minimum cash means looking at several things:
- Expected obligations: the payments over the horizon being analyzed, with their dates and priority.
- Expected collections: knowing the amounts isn't enough; you have to assess when they'll arrive and how reliable they are.
- Variability of flows: some companies have steady movements, others face significant swings in inflows and outflows.
- Available investments and financing: redeeming an investment or drawing on a credit line helps with temporary needs, as long as those funds are available within the time they're needed.
- Contingencies: late collections, unexpected payments or difficulty accessing funds.
With these elements, the organization can set a minimum liquidity policy and decide how to monitor it. The method it chooses has to be consistent with its operations, its policies and its risk tolerance.
5. An example: having money isn't having a surplus
Suppose a company faces this situation over the next fifteen days:
| Item | Millions |
|---|---|
| Cash available at the start | 10,000 |
| Expected collections | 4,000 |
| Expected payments | 6,000 |
| Projected cash on day 15 | 8,000 |
| Minimum available reserve | 6,000 |
On the surface, the company will end up 2,000 million above its minimum reserve. But on reviewing its collections, it finds that 3,000 million depends on a customer who might pay late. If that payment doesn't come in during the period, projected cash drops to 5,000 million, and the company goes from an apparent surplus of 2,000 to being 1,000 below its reserve.
There's another consideration: even if the closing balance is enough, a temporary financing need can appear if payments go out before collections come in. That's why judging whether cash is sufficient means looking at the lowest balance that could occur during the period, not just the closing one. That's what a day-by-day cash flow forecast shows.
A company can have plenty of money in its accounts and still not have a real liquidity surplus.
6. Does minimum cash have to stay the same?
Not necessarily. Liquidity needs change with the business. A company may need more funds around tax payments, debt maturities, one-off investments or busy seasons, and a bigger cushion when collections become more uncertain.
That's why some organizations set minimum levels by policy and others complement them with estimates that adjust to expected conditions.
What matters is telling two levels apart. The minimum available reserve is a safety limit: the balance the company doesn't want to fall below. The liquidity threshold is the balance above which money stops serving an operating purpose and becomes a surplus that can be invested. Between the two lies the band the company should operate in. Both levels can change with the horizon and the company's policy, and measuring the position against them is the basis of liquidity risk.
7. The challenge of many accounts and several companies
In organizations with many banks, several companies or several currencies, managing minimum cash is especially complex. There can be enough funds on a consolidated basis while specific accounts or companies still have needs of their own.
Funds can't always move freely: there may be legal, tax, currency, contractual or operational restrictions. That's why treasury needs to know not only how much money it has overall, but where it sits, who can use it and under what conditions it can be moved.
Consolidated liquidity gives an overall view, but it doesn't replace the analysis of each company, which is what a multi-entity treasury view that adds up without losing the detail makes possible.
8. How to tell whether there's money to invest
Once liquidity needs are identified, treasury can assess which funds could be invested. But a surplus isn't calculated by subtracting minimum cash from today's balance. You also have to consider the obligations due during the investment's term, how variable collections are, availability restrictions and reasonable adverse scenarios.
An investment can offer an attractive return and still be a poor choice if the funds are needed before it matures. That's why surplus cash investment has to be coordinated with the cash forecast. Return matters, but it's weighed together with safety and availability.
9. From fixed minimum cash to managing ahead
A common practice is to set certain cash limits and check from time to time whether they're met. That control is necessary, but it falls short when conditions change quickly.
Managing ahead means understanding how funds will evolve against expected obligations and what could change that path. That way potential shortfalls, temporary surpluses and financing needs are spotted in time, and you can check whether the minimum levels are still appropriate.
Technology and analytics help integrate information, keep forecasts current and assess scenarios. But setting minimum levels, investment policies and risk limits remains a well-founded decision by the people responsible for treasury.
10. The real question isn't how much money the company has
Managing liquidity well is a balancing act. With too few funds, operations are put at risk; with too many, returns are left on the table. No single figure resolves that tension for every organization: it depends on its obligations, how reliable its revenue is, the financing available, its risks and the decisions it needs to make.
That's why, rather than asking how much money the company has today, treasury should answer three questions:
- How much do we need to keep?
- How much can we use or invest?
- How will those needs change over the coming days?
Answering them moves you from managing balances to managing by actual and future liquidity needs.
FLIQO: intelligence to understand what's really available
Managing liquidity requires knowing the funds available, understanding future needs and having reliable information to decide.
FLIQO is an operational liquidity intelligence platform: it anticipates the path of cash with figures that are explainable and auditable, and compares it against the company's minimum available reserve and liquidity threshold, so treasury knows when it's short and when it has more than it needs.
Because a good decision doesn't start by asking only how much money there is. It starts by understanding how much is needed, when it's needed and what options there are to manage it.
Anticipate liquidity. Understand the figures. Decide with confidence.
