Intraday Liquidity and Central Bank Accounts
What you will learn
Your objective. By the end of this lesson, you will be able to explain intraday liquidity and central bank accounts. Every bank that participates directly in a payment system holds a settlement account at the central bank.
Why it matters. Intraday credit is usually collateralised, meaning the bank must pledge securities such as government bonds to secure it, and it is usually free or very cheap, because the central bank wants payments to flow smoothly.
Chapter objective: Learner manages intraday liquidity, explains funding sources, queues, and gridlock, and calculates a bank liquidity position from opening balance, inflows, outflows, and reserves. Learner applies this skill in realistic banking scenarios, with clear examples and correct terminology throughout.

Key terms
Intraday liquidity: Cash available to a bank during the business day to settle payments as they fall due. Intraday liquidity comes from account balances, incoming payments and central bank facilities.
Settlement: The final movement of funds between banks to discharge obligations created by cleared payments. Settlement is usually made in central bank money or through correspondent accounts.
Liquidity: Cash or assets that a bank can use immediately to meet payment obligations. Banks manage liquidity by forecasting inflows and outflows, funding nostro and settlement accounts, and using central bank...

Exercise
Decide which settlement model fits the scenario in this lesson and explain why.
Use the settlement models, the liquidity trade-off and the finality rules in this lesson.
- What to do. Name the model, state when settlement becomes final, and explain what happens if the sending bank does not have enough liquidity.
Correct result. Real time gross settlement settles each payment individually in central bank money with immediate finality, but it needs liquidity for every payment. Deferred net settlement nets payments and settles the net position, which needs less liquidity but leaves settlement risk until the net settles.
Why. Settlement is where money actually moves. The model decides the risk, the liquidity need, and when the payment is truly final.
Check your understanding
Practice question
A bank has many large RTGS payments queued at 10am but not enough liquidity on its account to settle them all. What is the practical consequence, and what tool helps?
Takeaway and next step
What to remember
A bank that cannot produce that check before the close of business is flying blind on its most expensive risk.
Settle a payment like the one in this lesson and watch the liquidity and finality behaviour.

Every bank that participates directly in a payment system holds a settlement account at the central bank. The balance in that account is the bank's primary source of intraday liquidity. At the start of the day, the balance reflects the bank's overnight position plus any funds it has moved in from other accounts. As payments settle, the balance falls when the bank sends payments and rises when it receives them. The bank's job is to keep the balance above zero all day, while using as little idle balance as possible, because idle balances earn little return. Central banks help by providing intraday credit, which is short term funding that a bank can draw on during the day and must repay before the close of business. Intraday credit is usually collateralised, meaning the bank must pledge securities such as government bonds to secure it, and it is usually free or very cheap, because the central bank wants payments to flow smoothly. The amount of intraday credit available, and the collateral required, are key parameters that shape how much liquidity a bank can access in a crisis. Banks also manage their intraday position actively. They monitor their balance in real time, forecast incoming and outgoing payments, and move funds between accounts when needed. Some payments are predictable, such as salary runs and known loan repayments, while others are not, such as large corporate payments that arrive without warning. Treasury teams use historical patterns, customer information and real time monitoring to build a forecast, and they adjust it through the day as actual flows differ from the forecast. The quality of this forecasting is a major determinant of how smoothly a bank settles. Work the numbers for one morning. Bank A starts the day with EUR 80 million in its central bank account. It also holds EUR 220 million of government bonds pledged as collateral for intraday credit. The central bank applies a haircut of 10 percent to the bonds, so the usable credit is EUR 198 million, not EUR 220 million. At 10 in the morning the bank draws EUR 60 million of intraday credit to cover a cluster of large outgoing payments, and by half past four in the afternoon the incoming payments have arrived and the credit is repaid in full. Intraday credit costs little or nothing, because the central bank wants payments to flow, but it must be repaid before the close of business. If the bank fails to repay, the intraday borrowing converts to overnight borrowing at a penalty rate, and the bank pays for the mistake. The forecast matters too. A salary run of EUR 45 million is predictable and is in the morning plan, but a corporate payment of EUR 30 million that arrives without warning is not, and treasury keeps a buffer for exactly that kind of surprise. An analyst specifies the machinery behind this in four places. First, the collateral eligibility list. Which securities the central bank accepts, and the haircut for each type. Second, the auto sweep rules. When surplus funds move out of the settlement account at the end of the day, and when funds move in. Third, the forecasting inputs. Known payment runs, customer information, and historical patterns, with a named owner for keeping them current. Fourth, the end of day check. A control that confirms all intraday credit is repaid and flags any balance that will convert to overnight borrowing. A bank that cannot produce that check before the close of business is flying blind on its most expensive risk.
