Understanding and managing liquidity risk

Most treasurers believe their cash is liquid until they need it and discover it isn’t. Liquidity risk is the difference between how quickly an asset seems convertible to cash and how quickly it actually converts when conditions change. This difference can determine whether an obligation is met on time or turns into a last-minute rush.

This guide explains what liquidity risk is and how it can show up. It also looks at how treasury teams manage liquidity in real situations, including where risks may be hidden in common cash structures businesses use.

What is liquidity risk?

Liquidity risk means an institution might not be able to turn an asset into cash quickly enough, or without taking a loss, to meet a payment when it’s due. This risk can affect a single asset or the whole balance sheet. A rarely traded bond has liquidity risk at the asset level, while a company unable to pay next week's payroll faces liquidity risk at the organisational level.

The two situations are connected but different. Treasury teams need to manage both, since a portfolio built from liquid assets can still leave an institution exposed if those assets aren’t available on the timeline its obligations demand.

Why liquidity risk is under closer watch

Liquidity risk has become a bigger focus for reasons that go beyond one institution’s balance sheet. Regulators now require banks to keep enough high-quality liquid assets to get through tough times, using rules like the Liquidity Coverage Ratio. Fund managers also face closer scrutiny, as the Financial Conduct Authority checks how well firms respond to liquidity risk in the funds they manage.

Companies face similar pressure, even without direct regulation. With recent financial volatility, from sudden rate changes to funding shifts, managing liquidity risk has become a necessary, ongoing task.

The two types of liquidity risk

Liquidity risk falls into two related types, each describing a different kind of problem. Market liquidity risk is when an asset can’t be sold at its expected price because there are few buyers and demand is limited. This can affect assets including corporate bonds and property, which need an active market to turn the investment into cash easily.

Funding liquidity risk is when an institution can’t fully make its payments on time, no matter how liquid its assets seem on paper. This risk is especially important for corporate treasury as it looks beyond theory, at reality. It’s about whether cash is actually available when a payment is due.

Liquidity risk isn’t the same as credit risk

People often mix up liquidity risk and credit risk, but they’re different problems. Credit risk is when a counterparty can’t pay back what it owes, no matter what is happening in the market. Liquidity risk is when an asset cannot be turned into cash quickly enough when needed.

A high-quality government bond has almost no credit risk. However, it can still create liquidity risk if it must be sold before maturity in a quiet market. This difference affects how treasury teams plan their cash strategies, since each risk requires its own management approach.

What causes liquidity risk in corporate cash

In corporate treasury, liquidity risk usually comes from a mismatch. If cash is put into investments that mature after the payments they are supposed to cover are due, a timing gap appears and can get worse under stress. Keeping most reserves with only one or two counterparties adds more risk. If one institution fails, it can block access to funds.

Unexpected cash needs make both problems worse. If a big customer payment is delayed, a manageable situation can quickly become a real funding gap. The same can happen if a supplier contract speeds up or if a market shock happens when a payment is due.

​None of this is unusual. It’s just part of normal business operations, which is why treasury teams need a planned response instead of assuming cash will always be available.

Measuring liquidity risk

Treasury teams usually begin by looking at liquidity ratios, which compare short-term assets to short-term obligations. The current ratio divides current assets by current liabilities. The quick ratio excludes inventory and other assets that convert more slowly to cash. The cash ratio is even stricter, comparing only cash and cash equivalents to liabilities due within a year.

These ratios provide a helpful overview, but they don’t show when cash will be needed during the year. A rolling cash flow forecast, tested with different scenarios, fills that gap. Combining ratio analysis with maturity laddering means investments mature in line with expected payments. This gives treasurers a clearer, more forward-looking view of their risks than either method alone.

Where liquidity risk hides in cash investment

Much surplus cash sits in structures designed to carry liquidity risk. A money market fund lets investors access their cash daily, but it holds investments that mature over a longer period. Regulators call this maturity transformation. This is a planned and disclosed part of the product. It means the fund’s liquidity depends on too many investors not withdrawing simultaneously.

An unsecured bank deposit has a similar risk because access to the cash depends only on the bank’s own liquidity. No asset backs the balance if the bank runs into trouble. A tri-party repo differs because collateral held by an independent party secures the cash during the trade. Maturity-matched structures, where the term is fixed and known from the start, remove the timing mismatch instead of just managing it.

Managing liquidity risk in practice

Good liquidity risk management starts with matching investment maturities to known payment dates, so cash isn't locked up longer than the business can wait. After that, most treasury teams use a few practical steps to build their approach:

• Laddering maturities across multiple dates over weeks and months.
• Spreading exposure across multiple counterparties and issuer types.
• Holding a mix of secured and unsecured positions, so access to cash doesn’t depend on a single structure.
• Running regular stress tests against scenarios, e.g. delayed receivables or a stressed counterparty
• Setting out the approach in a written treasury policy that survives changes in personnel

Taken together, these steps make liquidity risk management a regular part of treasury operations. Our guide on the role of a corporate treasurer explains how this discipline fits with other responsibilities.

Holding liquidity to a higher standard

Liquidity risk isn’t something you solve once and then ignore. It changes as the business changes, becoming more important as markets shift. Treasury teams that regularly measure liquidity risk with ratios, forecasts, and stress tests are better prepared to act early, rather than discovering a problem when a payment is already due.

How cash is held matters as much as the amount itself. Maturity-matched, secured investments remove some liquidity risks that pooled and unsecured options have by design. They do this without requiring treasurers to change the careful risk management they already use.
