What it means
Funding liquidity risk is about your own cash position: payroll is due on the 28th and the money is not there. Market liquidity risk is about the assets you hold: you own a warehouse worth $4,000,000 on paper but cannot convert it to cash this month without dropping the price sharply.
The risk matters because businesses are shut down by missed payments, not by low profits. A single unpaid supplier or breached loan covenant can trigger a chain of demands that a fundamentally sound company cannot answer in time.
Finance teams manage it by building a rolling cash forecast, holding a cash buffer, and arranging committed facilities such as an overdraft or revolving credit line before they are needed. The common measure is liquidity coverage: available cash plus undrawn facilities divided by expected net outflows over a defined stress period.
Concentration makes the risk worse in ways that are easy to miss. If one customer accounts for 40% of receipts, or one bank provides every facility you hold, a single late payment or credit review can turn a modest gap into an emergency.
Different businesses carry the risk in different shapes. A seasonal retailer knows its worst cash month a year in advance and can plan around it, while a project-based engineering firm can be caught out by one delayed milestone payment that was never expected to slip.
The important nuance is that liquidity risk tends to appear exactly when other things are going wrong. Lenders withdraw facilities and buyers demand discounts precisely when a business most needs cash, so a plan that relies on raising money in a crisis is not really a plan.
In practice
Real-world examples
Example 1
A property developer holds $30,000,000 of half-finished units but only $400,000 in cash when a contractor demands payment. The units cannot be sold quickly at full value, so the developer draws on an expensive bridging loan to avoid work stopping on site. The interest costs more than a year of the site's expected profit, which is the price of holding illiquid assets.
Example 2
A recruitment agency pays contractors weekly but invoices clients on 45-day terms. When its largest client stretches payment to 75 days, the agency faces a $600,000 funding gap and arranges invoice financing to bridge the timing mismatch.
Example 3
A food importer keeps all its banking with one lender. When that bank cuts its overdraft limit at renewal, the importer discovers it has no alternative facility in place and has to delay a shipment for six weeks. Two supermarket customers reduce their orders as a result, turning a funding problem into a revenue problem.
Think of it
Liquidity risk is like having a collection of rare coins: they're valuable, but if you need cash quickly, finding someone to buy them at the right price might be difficult.
Formula
Calculation
A common measure is the liquidity coverage ratio: (Cash and equivalents + Undrawn committed facilities) / Expected net cash outflow over the stress period. Take a manufacturer holding $2,000,000 in cash with a $1,500,000 undrawn revolving facility, so available liquidity is $2,000,000 + $1,500,000 = $3,500,000. Its 90-day stressed forecast shows net outflows of $2,800,000. The coverage ratio is $3,500,000 / $2,800,000 = 1.25, a surplus of $3,500,000 - $2,800,000 = $700,000. Expressed as time, the available liquidity covers ($3,500,000 / $2,800,000) x 90 = 112.5 days of stressed outflow.Case study
Seen in the real world
Harbour Lane Ceramics is an invented company used here as an illustrative case. On paper it was healthy, with $9,000,000 of assets and modest borrowings, but almost all its value sat in a freehold factory and eight months of glazed stock.
In an illustrative scenario, two large retail customers pushed payment terms out by 30 days in the same quarter. Cash fell from $850,000 to $180,000 while a $420,000 VAT payment and a $260,000 payroll run both fell due within a fortnight, and the factory could not be sold or mortgaged in time.
The owners negotiated a short deferral with the tax authority and arranged a $1,000,000 committed revolving facility for the future. They also introduced a 13-week rolling cash forecast and capped any single customer at 25% of receivables, which turned an unmanaged exposure into a monitored one.
Watch out
Common mistakes
- Assuming a profitable business cannot run out of cash, when profit is recorded on invoicing and cash arrives much later.
- Counting an uncommitted overdraft as guaranteed liquidity, when the bank can reduce or withdraw it at short notice.
- Forecasting only the average month and ignoring the specific weeks when tax, rent and payroll happen to fall together.
Questions
People also ask
How is liquidity risk different from insolvency?
Liquidity risk is being unable to pay on time despite owning enough value, while insolvency means liabilities genuinely exceed assets.
What is the simplest way to reduce liquidity risk?
Hold a cash buffer sized to your worst historic month and arrange a committed facility before you need it, since credit is cheapest when you are not desperate.
Does holding more inventory protect against liquidity risk?
No, it usually makes it worse, because stock ties up cash today in exchange for money that may only arrive months later.
