Funding Liquidity Risk vs Market Liquidity Risk Explained

Updated 11 October 2026 · Fact-checked

Liquidity risk is the risk that a bank cannot meet its cash obligations when due, or cannot trade an asset without a large price loss. Funding liquidity risk is the first; market liquidity risk is the second. To solve questions, identify which one is described, then trace how it feeds the other.

Understand Liquidity Risk Fundamentals and Sources

Liquidity risk has two faces. Funding liquidity risk is the risk that a bank cannot meet its payment and collateral obligations as they fall due, at acceptable cost, without hurting daily operations or its financial condition. Market liquidity risk is the risk that a position cannot be sold or offset quickly without moving the price, because the market is thin or disrupted.

Think of funding liquidity as the liability side and market liquidity as the asset side. A bank loses its deposits or cannot roll over repo: that is funding. A bank holds a corporate bond that nobody will bid for except at a deep discount: that is market liquidity. A signal of market illiquidity is a wide bid-ask spread, thin depth and slow price recovery after a trade.

The two interact. If funding dries up, the bank must sell assets to raise cash. In a stressed market those sales happen at fire-sale prices, which creates losses and erodes capital. Losses make lenders doubt the bank, so funding gets even harder. This is a liquidity spiral. It works in reverse too: when many institutions sell the same assets, market liquidity falls, collateral values drop, haircuts and margin calls rise, and funding needs jump.

Banks face liquidity needs from several sources. On the liability side: deposit withdrawals, especially from uninsured, wholesale or rate-sensitive depositors, and non-rollover of short-term wholesale funding such as repo and commercial paper. On the asset side: loan drawdowns and the inability to sell or pledge assets. Off-balance-sheet: drawdowns of committed credit lines and liquidity facilities, and derivative margin calls or collateral top-ups, for example after a rating downgrade. Other drivers are maturity mismatch, concentration in a few funding providers or currencies, intraday payment needs, and reputation or confidence shocks.

The root cause is that banks transform maturity: they fund long-term, illiquid assets with short-term liabilities. That is normal business, so liquidity risk cannot be removed, only measured, limited and covered by buffers.

Key formulas to remember

Funding liquidity risk: Cash outflows due > cash available (inflows + buffer + raisable funding); A liability-side concept: inability to meet obligations when due at acceptable cost.
Market liquidity cost (proportional spread): Relative spread = (Ask − Bid) ÷ Mid price, where Mid = (Ask + Bid) ÷ 2; Cost of a round trip is the full spread; selling one unit immediately costs about half the spread versus mid.
Liquidity gap: Net gap = Cash inflows − Cash outflows over a time bucket; A negative gap means funding must be raised or buffers used.
Liquidity spiral: Funding stress → asset sales → price falls → losses and higher haircuts → more funding stress; The core interaction of funding and market liquidity.

How to solve Liquidity Risk Fundamentals and Sources questions

Use this method for definition, scenario and source-identification questions.

1Read the scenario and decide whether the problem is on the liability side (cannot pay or roll over) or the asset side (cannot sell without price impact).
2Label it: funding liquidity risk, market liquidity risk, or both.
3Name the specific source: deposit run, wholesale non-rollover, credit line drawdown, margin or collateral call, maturity mismatch, or concentration.
4Trace the interaction: does funding stress force asset sales, or does a market freeze raise haircuts and margin calls?
5If numbers are given, compute the spread cost or the net cash gap and compare with the buffer.
6Match the answer to the exact wording of the question (definition, cause, effect or mitigant) and eliminate options that mix up the two risks.

Quickest way: Liability side or asset side

When to use it: For multiple-choice questions where two options differ only by swapping funding and market liquidity.

Ask: is the problem paying, or selling?
Paying or rolling over means funding liquidity. Selling at a discount or wide spreads means market liquidity.
If the scenario ends in forced sales causing losses, expect the spiral and choose the option linking both.
For spread arithmetic, divide (Ask − Bid) by the mid price, not by the bid.

Common mistakes in Liquidity Risk Fundamentals and Sources

Treating funding liquidity and market liquidity as the same thing.
Both are called liquidity and both worsen in a crisis.
Fix: Funding is about meeting obligations (liabilities); market is about trading assets at fair prices (assets).
Assuming an insolvent bank is the same as an illiquid bank.
Both can fail at the same time in a crisis.
Fix: A solvent bank can run out of cash. Liquidity is about timing of cash; solvency is about assets exceeding liabilities. Losses from fire sales can link the two.
Ignoring off-balance-sheet sources of liquidity needs.
Students focus on deposits and loans.
Fix: Always check committed lines, guarantees, and derivative margin or downgrade-triggered collateral calls.
Dividing the spread by the bid instead of the mid price.
Rushing through the calculation.
Fix: Relative spread = (Ask − Bid) ÷ Mid. Compute mid first.
Saying liquidity risk can be eliminated by holding enough capital.
Confusing capital with liquid assets.
Fix: Capital absorbs losses; liquid buffers meet cash needs. Capital does not itself provide cash.

Worked examples

Example 1

A bank funds 40% of its assets with overnight repo secured on corporate bonds. A market shock widens bond spreads, lenders raise haircuts, and the bank must sell bonds at a discount. Which statement best describes this?

Show the solution

Overnight repo that lenders will not roll or will roll only with higher haircuts is a funding liquidity problem.
Selling bonds at a discount in a thin market is market liquidity risk.
Discount sales cause losses and lower collateral values, which raises haircuts further.
So both risks are present and reinforce each other.

Answer: A liquidity spiral: funding liquidity risk (higher repo haircuts) and market liquidity risk (fire-sale discounts) interact.

Example 2

A bond is quoted at bid USD 98.40 and ask USD 98.80. Compute the relative bid-ask spread and the approximate cost of selling immediately for a USD 50 million face value position at the bid, relative to mid.

Show the solution

Mid = (98.40 + 98.80) ÷ 2 = 98.60.
Spread = 98.80 − 98.40 = 0.40.
Relative spread = 0.40 ÷ 98.60 = 0.4057%, about 0.41%.
Selling at the bid costs half the spread: 0.20 per 100 face, which is 0.20 ÷ 100 = 0.002 of face.
Cost = 0.002 × USD 50,000,000 = USD 100,000.

Answer: Relative spread is about 0.41%; selling immediately at the bid costs about USD 100,000 versus mid.

Exam tips

Questions often hide the answer in one phrase: unable to roll over means funding, unable to sell without a price drop means market.
Expect scenarios where one risk triggers the other. Choose the option that explains the feedback loop.
Remember the sources outside the balance sheet: credit line drawdowns and collateral calls.
For spread questions, check whether the question asks for the full spread or the cost of one-way trade; the latter is half.

Liquidity Risk Fundamentals and Sources: frequently asked questions

What is the difference between funding liquidity and market liquidity?

Funding liquidity is the ability to meet cash and collateral obligations when due. Market liquidity is the ability to trade an asset quickly without moving its price much. One concerns liabilities, the other assets.

How do funding and market liquidity risk interact?

Funding stress forces asset sales, which push prices down in illiquid markets. Falling prices cause losses, higher haircuts and margin calls, which increase funding stress. This feedback is called a liquidity spiral.

What are the main sources of liquidity needs for a bank?

Deposit withdrawals, failure to roll over wholesale funding, drawdowns of committed credit lines, margin and collateral calls, and intraday payment needs. Maturity mismatch and funding concentration make these needs more dangerous.

Can a solvent bank face a liquidity crisis?

Yes. A bank can have assets worth more than its liabilities but still lack cash when obligations fall due. This is why liquidity buffers are needed in addition to capital.
