Liquidity Risk for FRM Part II: Study Guide

Liquidity risk is the risk of losing value because you cannot trade an asset at a fair price (market liquidity) or cannot meet cash obligations when due (funding liquidity). To solve questions, identify which type it is, apply the right measure (spread cost, LVaR, LCR or NSFR), then interpret the result.

What this chapter covers

This chapter covers two linked ideas. Market liquidity risk is the cost of exiting a position: bid-ask spreads, price impact and the time needed to sell. Funding liquidity risk is the risk that a firm cannot raise cash or roll over debt without unacceptable cost or failure. The chapter moves from measuring trading costs, to adding them to VaR, to how funding strain spreads in a crisis, to how banks test for it and how Basel rules set minimum buffers.

You will see the same tools used for numbers and for judgement. Numerical questions ask you to compute a half-spread cost, an LVaR add-on, or an LCR and NSFR ratio. Conceptual questions ask you to match a situation to a mechanism, such as a run, a margin spiral or a mismatch between assets and liabilities.

The chapter ties directly to the rest of FRM Part II. It builds on market risk measurement, since LVaR extends VaR. It connects to credit risk through counterparty and collateral effects. It links to risk management in investment management, where fund redemptions and illiquid assets matter. It also links to current issues such as private credit and digital assets, where liquidity mismatch is a recurring theme.

The exam has 80 equally weighted multiple-choice questions across six topics, and liquidity risk sits inside the Liquidity and Treasury Risk Measurement and Management topic. The content is formula-light but concept-heavy, so careful candidates can score reliably. The same ideas, such as liquidity mismatch, run dynamics and buffers, also help you answer questions in market risk, credit risk and investment management. Questions are applied and case-like, so you need the measure, the method and the interpretation, not just definitions.

Liquidity Risk: topics in the order to study them

  1. 1Market Liquidity Risk and Bid-Ask SpreadsStart here because spreads and price impact are the building blocks for everything that follows.
  2. 2Liquidity-Adjusted VaR (LVaR)It adds the spread cost to VaR, so it needs the spread ideas first and your market risk VaR knowledge.
  3. 3Funding Liquidity Risk and Liquidity CrisesMove from trading costs to the firm's cash position, and learn how funding and market liquidity feed each other.
  4. 4Liquidity Stress Testing and Contingency Funding PlansStress tests and plans make sense only once you know the funding risks and crisis channels they address.
  5. 5Liquidity Risk Regulation: LCR and NSFRFinish with the Basel ratios, which are the regulatory answer to the risks you have now studied.

How to prepare Liquidity Risk

Aim to be able to compute each measure and explain what it tells a risk manager. Work in short sessions that suit phone study, and practise with applied questions.

  1. Read the topics in the study order and write a one-line definition of market liquidity risk and funding liquidity risk in your own words.
  2. Practise the spread cost calculation: cost = position value × half the relative spread, where relative spread = (ask − bid) ÷ mid-price. Do several examples with different positions.
  3. Rework LVaR step by step: compute ordinary VaR, compute the liquidation cost from the spread, then add them. Check whether the question uses the exogenous spread approach.
  4. Make a table on paper of the crisis channels: runs, margin and haircut increases, collateral calls, and asset fire sales. Note how each connects to the others.
  5. Learn the LCR and NSFR formulas and what counts in each part: LCR = high-quality liquid assets ÷ net cash outflows over 30 days, with a minimum of 100%; NSFR = available stable funding ÷ required stable funding, with a minimum of 100%.
  6. Do timed mixed question sets, and for every miss write down whether the error was in the concept, the formula or the reading of the question.
  7. In the last week, review your error notes and the quick revision list instead of reading new material.

Common mistakes in Liquidity Risk

  • Using the full spread instead of half the spread as the cost of liquidating.

    Fix: Always check the reference price. If it is the mid-price, the cost is half the spread times the position size.

  • Treating LVaR as a separate measure that replaces VaR.

    Fix: Compute ordinary VaR first, then add the liquidity cost. State both parts in your working.

  • Mixing up LCR and NSFR horizons and components.

    Fix: Remember LCR is a 30-day stock of liquid assets against net outflows, while NSFR compares stable funding with the funding needed for assets over a year.

  • Confusing market liquidity with funding liquidity in case questions.

    Fix: Ask what the problem is: selling assets at a fair price points to market liquidity; paying obligations or rolling debt points to funding liquidity.

  • Describing stress testing as a single forecast.

    Fix: Treat stress testing as scenario analysis across horizons and shocks, used to size buffers and trigger the contingency funding plan.

  • Memorising ratios without interpreting them.

    Fix: For every ratio, state what a result below or above 100% means and what a risk manager should do next.

Last-day revision: Liquidity Risk

  • Market liquidity risk is the cost or difficulty of trading; funding liquidity risk is the inability to meet cash obligations when due.
  • Relative spread = (ask − bid) ÷ mid-price.
  • Cost of liquidating a position = position value × half the relative spread.
  • LVaR = VaR + liquidity cost, where the cost comes from the spread assumption given.
  • Wider or more volatile spreads raise the LVaR add-on.
  • Ordinary VaR ignores the cost of exiting a position, so it understates risk for illiquid holdings.
  • Liquidity spirals: falling prices raise margins and haircuts, forcing sales, which push prices down further.
  • Maturity mismatch between assets and liabilities is the core source of funding liquidity risk.
  • A contingency funding plan sets triggers, responsibilities and funding sources for a stress event.
  • LCR = high-quality liquid assets ÷ total net cash outflows over a 30-day stress period; the minimum is 100%.
  • NSFR = available stable funding ÷ required stable funding over a one-year horizon; the minimum is 100%.
  • LCR addresses short-term resilience; NSFR addresses structural funding over a longer horizon.

Liquidity Risk: frequently asked questions

Is liquidity risk a formula-heavy chapter in FRM Part II?

No. It has a few key calculations such as spread cost, LVaR, LCR and NSFR. Most questions test whether you can apply the concept to a case and interpret the result.

What is the difference between LCR and NSFR?

LCR checks that a bank holds enough high-quality liquid assets to cover net cash outflows over a 30-day stress period. NSFR checks that long-term assets are backed by sufficiently stable funding over a one-year horizon. Both have a minimum of 100%.

How do I add liquidity cost to VaR?

Compute the usual VaR, then compute the cost of liquidating the position from the bid-ask spread. Add the two to get LVaR. Use the spread assumption stated in the question.

How long should I spend on this chapter?

Spend enough time to calculate each measure without notes and explain each crisis mechanism in a few sentences. Revisit it near the exam, since it links to market risk, credit risk and investment management.
