Liquidity Early Warning Indicators: Eight Signals

In practice, a liquidity squeeze may be noticed only when it becomes clear that a payment cannot be made. By then the options have narrowed: bank limits are used up, suppliers are starting to ask for cash in advance, and there is no time left to negotiate terms with customers. The purpose of early warning indicators is to make this picture visible weeks or even months earlier.

The signals below are a general framework. Each company should set its own thresholds according to its business model. What follows are trends to monitor, not recommended thresholds.

Eight signals

#	Signal	How to measure	Why it matters
1	Longer collection periods	Monthly days sales outstanding (DSO) and overdue receivables	Cash inflow lags even while sales continue
2	Change in a large customer’s payment behaviour	Payment-day variance of the largest customers	Risk concentrates in a few customers
3	Inventory growing faster than sales	Days inventory outstanding (DIO) and slow-moving stock	Cash is tied up in stock
4	Shorter supplier terms	Days payables outstanding (DPO) and number of suppliers asking for cash in advance	Supplier confidence may be falling
5	Credit lines constantly near their limit	Monthly trend in utilisation	No buffer remains
6	Short-term debt funding long-term spending	Funding source of capital expenditure	A maturity mismatch builds up
7	Persistent cash forecast misses	Forecast versus actual cash	The plan becomes unreliable
8	Tax, social security or payroll payments postponed	Delays in the payment calendar	May indicate a late stage of the squeeze

Reading the signals

Working capital signals (1–4): These four signals relate directly to the cash conversion cycle. A longer cycle increases the need for cash even when profit is unchanged. For the calculation, see the cash conversion cycle.

Funding signals (5–6): Limits that are always full show that there is no buffer to absorb an unexpected delay. Funding investment with short-term credit creates a sudden cash need if the credit is not rolled over.

Management signals (7–8): Persistent forecast misses show that the planning process itself needs review. Postponing mandatory payments is no longer an early warning but a late one.

A legal warning threshold in Türkiye: loss of capital and over-indebtedness

Separately from cash indicators, the Turkish Commercial Code provides a balance-sheet-based warning mechanism for joint-stock companies. Under Article 376:

• If the latest annual balance sheet shows that half of the total of share capital and statutory reserves is uncovered as a result of losses, the board must call the general assembly immediately and present the remedial measures it considers appropriate.
• If two thirds of that total is uncovered and the general assembly, called immediately, does not resolve to make do with one third of the capital or to restore the capital, the company is dissolved by operation of law.
• If there are signs suggesting that the company may be over-indebted, the board prepares an interim balance sheet on both a going-concern basis and at the probable sale prices of the assets. If that interim balance sheet shows that the assets are not sufficient to cover the company’s creditors, the board notifies the commercial court of first instance where the company has its seat and requests the company’s bankruptcy; the Code makes an exception conditional on creditors whose claims are sufficient to cover the deficit accepting subordination of their claims in writing, verified by experts appointed by the court.

Because these provisions have legal consequences, their application should be assessed with a lawyer. What matters from a finance point of view is seeing in advance that these thresholds are being approached.

Monitoring routine

1. Weekly: Cash position, collections from the largest customers, limit utilisation. See the weekly cash meeting.
2. Monthly: DSO, DIO, DPO, overdue receivables, forecast variance.
3. Periodically: Equity and capital position, debt maturity profile.

Write down an owner and an action for each signal, for example: “if one of the three largest customers pays two weeks late, sales and finance meet together”.

Common mistakes

• Looking only at the cash balance: The balance is the result of the signals; it does not show the cause.
• Reading signals in isolation: Collection delays and rising limit utilisation at the same time are more serious than either seen alone.
• Not setting thresholds: If it is not written down when to act, the decision is delayed even when the signal is seen.
• Taking bad news to the board late: The time available for action shrinks.

What it means for management

A liquidity squeeze may give warning in advance. Monitoring the eight signals regularly gives management time to talk to banks, customers and suppliers before the squeeze arrives. When the signals worsen, the next step is a weekly cash plan supported by scenarios; for the method, see the collection delay stress test.
