Intraday Liquidity Risk Basics for FRM Part II

Updated 11 October 2026 · Fact-checked

Intraday liquidity is the funds a bank can access during the business day to make payments and settle obligations in real time. Intraday liquidity risk is the risk that it cannot meet those payments when due. Solve questions by finding timing gaps between payments sent and received, and the buffer covering them.

Understand Intraday Liquidity Risk Basics

Banks do not only pay and receive money at the end of the day. Thousands of payments move through payment and settlement systems from morning to evening. Each payment needs funds at the moment it is sent. Intraday liquidity is the funds a bank can access during the business day to settle these payments in real time.

Intraday liquidity risk is the risk that a bank cannot meet its payment and settlement obligations on time during the day. It may still be solvent and may still end the day with enough cash. The problem is timing. If your outgoing payments leave before your incoming payments arrive, you need funds to bridge the gap.

This matters because payments are linked. If bank A delays a payment, bank B receives less cash than expected. Bank B may then delay its own payments to bank C. A shortfall at one bank can spread through the system. Banks may also hold back payments to conserve liquidity, which makes the problem worse for everyone.

Banks get intraday liquidity from their balance at the central bank, incoming payments from other banks, secured intraday credit from the central bank against collateral, and other available assets and credit lines. They use it for customer payments, interbank payments and settlement of securities and FX trades.

Intraday risk differs from overnight liquidity risk in horizon and measurement. Overnight (and longer) liquidity risk is about the funding position at the close of the day and beyond, such as the next day's funding need. Intraday risk is about the path of the balance during the day, including peak usage and timing of flows. A bank can be fine at the close and still face stress at 11am. Under stress, such as a counterparty failing to pay, intraday needs can rise sharply.

Key formulas to remember

Net cumulative position: Net cumulative position at time t = Σ payments received up to t − Σ payments sent up to t; A negative value means the bank has used its own liquidity (or intraday credit) to fund payments. Check the sign convention in the question.
Daily maximum intraday liquidity usage: Maximum usage = largest cumulative net outflow during the day (the lowest point of the net cumulative position, if negative); This is the peak need, not the end-of-day position. Sized against the available intraday liquidity.
Available intraday liquidity: Available = central bank balance at start of day + collateral that can be pledged for intraday credit + other intraday sources; Compare this with peak usage to see whether the bank has a sufficient buffer.
Intraday liquidity headroom: Headroom = Available intraday liquidity − Maximum intraday usage; A negative result means a shortfall at the peak.

How to solve Intraday Liquidity Risk Basics questions

Use this method for any question on the basics of intraday liquidity risk, whether it is conceptual or numerical.

1Identify the horizon. Is the question about the payment day (intraday) or the close of day and later (overnight or longer)?
2List the intraday sources: opening central bank balance, incoming payments, intraday credit against collateral, other available funds.
3List the intraday uses: customer payments, interbank payments, securities and FX settlement, and any delayed receipts.
4For numerical questions, build the running net position through the day and find its lowest point.
5Compare the peak need with available intraday liquidity to find headroom or shortfall.
6Check the stress angle. Does the question involve a delayed receipt, a counterparty failure, or a payment system disruption? These raise the peak need.
7Pick the option that matches the timing logic: intraday risk is about timing and the path of the balance, not just the end-of-day figure.

Quickest way: Peak versus buffer check

When to use it: Use for numerical questions that give a timeline of payments and ask about the shortfall or needed buffer.

Write each flow with its time, receipts as plus and payments as minus.
Add them in time order to get the running total.
Circle the lowest running total. That is the peak usage.
Subtract it from the available liquidity. Negative means shortfall.
For concept questions, eliminate options that mention only end-of-day balances.

Common mistakes in Intraday Liquidity Risk Basics

Treating intraday liquidity as the same as overnight liquidity.
Both involve having enough cash, so they look alike.
Fix: Remember the horizon. Intraday is about timing within the day. Overnight is about the position at close and funding for the next day.
Using the end-of-day balance to judge intraday risk.
The closing balance is the easiest number to read.
Fix: Look for the lowest point of the running balance. A positive close can hide a large intraday deficit.
Assuming a solvent bank cannot have an intraday problem.
Liquidity and solvency get mixed up.
Fix: A bank with ample capital can still face a timing gap if its receipts arrive late.
Ignoring the contagion effect of delayed payments.
Students think only about one bank.
Fix: Remember payments are linked. One bank's delay reduces others' receipts and can lead them to delay too.
Forgetting central bank intraday credit as a source.
Students list only cash and incoming payments.
Fix: Include intraday credit against eligible collateral. Remember it needs collateral, so it is not free.
Getting the sign wrong in the running net position.
Questions switch between net outflow and net position.
Fix: Define receipts as plus and payments as minus before you start, and state which one the answer asks for.

Worked examples

Example 1

A bank starts the day with a central bank balance of $500 million and no other intraday sources. During the day: 9:00 it sends $300 million; 10:00 it receives $100 million; 11:00 it sends $400 million; 13:00 it receives $450 million; 15:00 it sends $100 million. What is the maximum intraday liquidity usage, and what is the headroom?

Show the solution

Use receipts as plus and payments as minus. Running net position of flows.
After 9:00: −300.
After 10:00: −300 + 100 = −200.
After 11:00: −200 − 400 = −600.
After 13:00: −600 + 450 = −150.
After 15:00: −150 − 100 = −250.
The lowest point is −600 at 11:00, so maximum usage is $600 million.
Headroom = 500 − 600 = −100, so there is a shortfall of $100 million at the peak.

Answer: Maximum usage is $600 million. Headroom is −$100 million, a shortfall at 11:00 even though the day ends with only a $250 million net outflow.

Example 2

Bank X has enough funds to cover its overnight funding needs and ends each day with a surplus. Yet it often has to delay payments late in the morning. Which statement best explains this?

Show the solution

The bank is fine at the close, so overnight liquidity looks adequate.
Delays happen in the morning, so the issue is the timing of flows within the day.
This is a mismatch between payments sent and payments received during the day, which is intraday liquidity risk.
The end-of-day surplus does not show the intraday peak need.

Answer: Bank X faces intraday liquidity risk. Its intraday liquidity is insufficient at the peak of the day because outgoing payments run ahead of incoming ones, even though its end-of-day and overnight positions are adequate.

Exam tips

Look for timing words such as during the day, real time, peak and settlement. They signal intraday liquidity.
In numerical questions, find the lowest running position, not the final one.
When an option talks only about the closing balance or overnight funding, it is usually the wrong choice for an intraday question.
Remember the contagion link: delayed payments by one bank can cause delays at others.
Know the sources and uses of intraday liquidity well, since conceptual questions often ask you to classify items.

Practice questions from Intraday Liquidity Risk Management

Intraday Liquidity Risk Basics: frequently asked questions

What is intraday liquidity risk?

It is the risk that a bank cannot meet its payment and settlement obligations on time during the business day. The cause is usually a timing gap between payments sent and payments received.

How is intraday liquidity different from overnight liquidity?

Intraday liquidity concerns the funds needed to settle payments at each moment of the day. Overnight liquidity concerns the funding position at the close of the day and the need for the next day. A bank can be fine overnight and still face intraday stress.

Why is intraday liquidity important for banks?

Banks must settle payments for customers and other banks in real time. If they cannot, payments are delayed, other banks receive less cash, and the problem can spread across the payment system.

Can a solvent bank face intraday liquidity risk?

Yes. Solvency is about capital and the value of assets. Intraday risk is about timing of cash flows, so even a well-capitalised bank can face a shortfall if receipts arrive late.
