What must be funded, and by when
A settlement position is the amount an institution must pay or receive, by a given deadline, on an infrastructure it participates in. An institution that acquires, issues, or transfers money holds several positions at once, each with its own deadline and currency. A net balance owed to a card network follows a contractual calendar, whereas a gross position in a wholesale settlement system builds up order by order. The creditor also differs from one position to the next: a card network in one case, a clearing house, a central bank, or a correspondent bank in others. Managing a settlement position means determining, before the day opens, the amount due under each of these obligations and the time it falls due. Adjustments made during the day then close the gap between that forecast and actual flows.
The card payment chain separates the moment of purchase from the moment funds move between banks. Authorization places a hold on the cardholder’s account and commits the issuer, but it moves no money between banks. No liquidity is called at this stage. The obligation arises at clearing, when the acquirer submits the transaction to the network’s system: BASE II for Visa, the Global Clearing Management System for Mastercard. The network calculates a net position for each member, settlement currency, and cycle, then reports it in its settlement reports. The member in a debit position funds that amount before the network’s cutoff, on the date set by the settlement calendar for the currency. Several days can therefore pass between the purchase and the funding call: a Saturday payment can trigger a funding call the following Tuesday.
| Obligation | Who sets the amount and the time | When the amount becomes known | What happens if it isn’t covered |
|---|---|---|---|
| Net position with a card network | The network, through its settlement rules and currency calendar | After the clearing cycle, through settlement reports | A call on posted collateral, then contractual measures by the network against the defaulting member |
| Net position at a retail clearing house (SEPA bulk payments, domestic ACH) | The clearing house, through its cycles and settlement times | At the end of the exchange cycle | The clearing house’s default procedure, which can go as far as unwinding a cycle |
| Gross position in an RTGS system | Each order individually, as it comes in | Continuously, order by order | Queued, then rejected at the close and resubmitted the next business day |
| Prefunded balance on an instant rail | The rail, which rejects any payment above the available balance | In real time, with each payment sent or received | Payment rejected immediately, with no queue and no second chance |
| Merchant payout | The merchant agreement, regardless of the network calendar | As soon as the day’s sales are closed out | Breach of the merchant agreement, with immediate commercial consequences |
| Funding a nostro account | The correspondent bank, through its own cutoff | Based on advices received, often late in the day | Payment not executed, or an overdraft charged by the correspondent |
Clearing is the process by which a clearing house nets the instructions exchanged during a cycle and passes only the resulting balance to the wholesale settlement system. The participant’s funding need is then limited to that balance, which is smaller than the total amount exchanged. The trade-off is visibility: the final position is known only when the cycle closes. A gross system works the other way around. It requires the full amount at the moment of the order and leaves no doubt about what has settled. A treasury operating on both models therefore produces two forecasts of different kinds, one per cycle and one continuous. The two do not add up to a single number.
A cutoff is the time after which an instruction is no longer accepted for the current day. Almost every rail has three distinct cutoffs layered on top of each other. The customer cutoff closes payments made on behalf of third parties. The interbank cutoff, which comes later, closes the system itself. A third cutoff, internal to the institution or its provider, falls between the two and comes ahead of the interbank close to leave time for compliance checks and bulk processing. The only time that matters for covering a debit position is the last moment liquidity can still be brought into the settlement account. The rail’s marketing materials rarely state that time. Mixing up these three cutoffs leads institutions to cover a position too late, after the last moment liquidity could still be received.
- The settlement currency, which differs from the transaction currency. A payment taken in Swedish kronor and settled in euros requires a foreign exchange transaction with a value date ahead of the funding cutoff.
- The clearing cycle used, daily or intraday, which determines how much time passes between the sale and the funding call.
- Membership type, direct or sponsored. An indirect member is bound by its sponsor’s cutoffs, which are earlier than the network’s.
- Required collateral. Visa and Mastercard rules allow the network to require a member to post collateral based on its risk profile, and that collateral is tied up and unavailable for operations.
- The usual net direction of the position. A pure issuer is structurally in debit to the network, a pure acquirer structurally in credit, and a mixed business swings between the two depending on the day of the week.
Instant rails: prefunded because they never close
An instant rail settles each payment in seconds, at any hour, with no queue and no clearing. Prefunding is the requirement for a participant to hold in its settlement account, before placing the order, the amount it wants to send. None of those three properties is possible unless the money is already there when the order is placed. The system checks the payer’s available balance and rejects the payment if it falls short. Settling without prefunding would mean extending credit with no human decision, overnight, to participants whose creditworthiness can’t be assessed at that moment. All four rails described below rule that out. Prefunding is the direct trade-off for immediate finality, and it shifts the liquidity constraint from the settlement engine to the participant’s balance sheet.
| Rail | Where the money sits | Top-up window | What happens when the balance falls short |
|---|---|---|---|
| TIPS (Eurosystem) | A dedicated TIPS cash account in central bank money, separate from the main cash account | By liquidity transfer from the main cash account, only while T2 is open | The payment is rejected immediately; the rail keeps running for other participants |
| RT1 (EBA Clearing) | A fully prefunded position on a technical account in the system, set up before the exchange | While the euro wholesale system is open | The payment is rejected, since a participant’s position can never go into debit |
| FedNow (Federal Reserve) | The participant’s master account at a Federal Reserve Bank | Fedwire during business hours, and liquidity transfers between participants during the windows the service provides | Rejected, since the service offers no daylight overdraft outside standard Fedwire hours |
| RTP (The Clearing House) | A joint account held by participants at the Federal Reserve Bank of New York, with individual position tracking | Funding of the joint account while wholesale settlement is open | Rejected, since a participant’s individual position can never fall below zero |
The Eurosystem implements this prefunding in TIPS through a dedicated cash account. That account holds only the liquidity set aside for instant payments and is funded from the main cash account through explicit transfers. TIPS runs around the clock, seven days a week, while the component that holds the main cash account follows the TARGET calendar and closes every evening. Between the evening close and the next morning’s opening, the balance on the dedicated account caps what the participant can send. The central bank extends no credit line on that account, and no transfer from the main cash account is possible while the component that holds it is closed. During that closure, only movements within the service can still credit the dedicated account: incoming instant payments and liquidity transfers inside TIPS.
The net direction of flows matters more than gross volume when sizing a prefunded account. A net sender pays out more than it receives over the period, which is the structural position of disbursement providers, payroll processors, and refund platforms. Their prefunded balance falls throughout the closure window, because incoming payments don’t offset outgoing ones. A net receiver, by contrast, builds up an idle balance that it can only sweep back when the system reopens. The first profile needs a large buffer and an early alert; the second needs an automatic sweep as soon as the system opens. A single group often has both profiles in two separate entities, with treasuries managed separately.
Indirect access means participating in a rail through a direct participant, called a sponsor. The indirect provider settles through the sponsor’s account, within a capacity limit that the sponsor allocates and monitors. The liquidity constraint doesn’t go away; it just shifts to someone else. The provider’s actual capacity is set by a contract clause negotiated with the sponsor, not by the system rules. In Europe, Regulation (EU) 2024/886 amended the Settlement Finality Directive to open direct participation to payment institutions and e-money institutions. Member states had to transpose this change by April 9, 2025. A nonbank provider can therefore seek a settlement account in its own name, provided it takes on the ongoing operational obligations that come with it.
Collateral: what it ties up and what it frees
Intraday credit is an advance from a central bank that can be used during the day and must be repaid before the close. A participant that wants to settle more than it holds pledges eligible assets with its central bank and receives this credit line in return. The line lasts only hours and sometimes carries no interest, two features that set it apart from an ordinary loan. However, it ties up a pool of assets that can’t be used for anything else that day. The participant’s real cost therefore lies in immobilizing those assets, not just in the price of the line. Uncollateralized overdrafts are available only in some jurisdictions, and they come at a price.
Collateral is mobilized using one of two techniques: pooling or earmarking. Pooling creates a reserve of assets whose total value backs all of the participant’s operations, with no security assigned to any specific operation. Earmarking ties each asset to an identified operation, which allows closer tracking but requires more administration. In both cases, the value used is the market value minus a haircut. The haircut depends on the asset class, its credit quality, and its residual maturity. A pool that looks large on paper can therefore provide significantly less settlement capacity than its face value suggests.
| Jurisdiction | How capacity is obtained | Intraday cost | What happens at the close |
|---|---|---|---|
| Euro area | Intraday credit secured by assets pledged with the national central bank, managed in ECMS since June 2025 | No intraday interest; the cost is tying up the assets | Unrepaid credit is automatically converted into recourse to the marginal lending facility, charged at that facility’s rate |
| United States | A net debit cap based on a capital measure and a multiplier, plus collateralized capacity above the cap | Free on the collateralized portion; 50 basis points annualized on the uncollateralized portion since March 2011 | An overdraft still outstanding after the close becomes an overnight overdraft, subject to the penalty regime of the Policy on Payment System Risk |
| United Kingdom | Intraday liquidity provided to direct CHAPS participants against eligible collateral under the Sterling Monetary Framework | The cost of tying up collateral, plus throughput criteria that require paying early in the day | Use of the standing facilities, at a cost far higher than intraday credit |
Auto-collateralization is intraday credit granted within securities settlement, secured either by the securities the participant is buying or by securities it already holds in its account. The credit is repaid when the cash comes in, and the position settles without any assets having to be pledged in advance. The mechanism reduces liquidity needs during peak securities settlement hours. It still depends on the underlying transaction actually settling. If settlement fails at the end of the day, the credit stays open and triggers a collateral call the participant hadn’t planned for.
Collateral is released after the line is repaid, which in turn depends on receiving the expected inflows. The sequence gets tight when a correspondent pays late, a counterparty delays a delivery, or a technical incident pushes back a clearing cycle. At the close, an institution that hasn’t repaid its line must fall back on end-of-day funding, which costs far more than intraday credit. Releasing the assets also takes time: a return instruction sent after the custodian’s cutoff frees the securities only the next day. Full unwinding therefore involves two steps, repaying the line and then getting the assets back, each with its own cutoff.
Calendars, and the shifts they cause
The calendar that governs a settlement is the calendar of the settlement currency, set by the operating days of the infrastructure that processes it. Public holidays in the payer’s and the payee’s countries have no effect on that date. A French institution settling in dollars therefore follows the operating days of US infrastructure, including on July 14, France’s national holiday. A US institution settling in euros stops on Easter Monday, a business day at home. This mismatch creates situations where one leg of an FX transaction can’t settle. The calendar for every currency handled belongs in the payment engine’s configuration, just like cutoffs.
| Reason | What it causes | What to prepare |
|---|---|---|
| Weekly closure of wholesale settlement | Two days when instant rails keep running with no way to top up | A prefunded balance sized for the weekend peak outflow, not the weekly average |
| TARGET closing days (January 1, Good Friday, Easter Monday, May 1, December 25 and 26) | No euro value date, while other currencies remain open | Contractual due dates shifted, and euro positions funded in advance |
| A holiday in only one of the two currencies in an FX transaction | One leg settled, the other pending, with exposure to the full amount | Check that both systems are open before committing, not after |
| Card cycles piling up on closed days | A single funding call covering several days of trading | Funding set aside for the full number of days, especially over long weekends and at year-end |
| Month-end, quarter-end, and year-end | Direct debits, payroll, coupons, and tax deadlines concentrated on a handful of dates | Forecasting by value date rather than monthly average, with collateral freed up in advance |
| Long closures specific to one market | Several consecutive days without settlement in a given currency | An annual review of the calendars for every currency handled, updated as soon as they are published |
Weekend card accumulation refers to bundling transactions cleared while the settlement system is closed into a single settlement. Card networks clear transactions every day, but funds move only on the days the settlement system for that currency is open. An acquirer whose merchants take payments on Friday, Saturday, and Sunday therefore receives a settlement covering three days of sales on the next business day. Meanwhile, if its contract promises daily payouts, its payout obligations keep running without interruption. The gap between amounts paid out and amounts received peaks on the last day of the closure. Because the date of that peak is known in advance, its size can be calculated from payment data for previous closures.
Period-ends are the days when an institution’s recurring payment dates cluster. Bulk direct debits, payroll transfers, coupon payments, and tax deadlines fall on the last business days of the month and the first ones of the next. In the euro area, minimum reserve requirements add their own cycle. An institution averages its balance over the entire maintenance period, so a surplus one day offsets a shortfall on another. A forecast expressed as a monthly average spreads these amounts across every day and flattens the peaks. Only forecasting by value date, fed by known payment schedules, puts each payment back on its actual date and positions collateral at the right time.
Seasonal acceptance peaks are the days when card volumes jump for commercial reasons. Major year-end promotional days, religious holidays, and back-to-school periods create these peaks over just a few days, and net positions with the card networks rise. These days often come right before a closure, so the volume effect stacks on top of the accumulation effect. An acquirer that sizes its year-end funding on the previous month finds the gap the following Monday. Merchants and networks publish volumes for these days after the fact, and the figures are rarely comparable from one year to the next. An internal forecast based on the institution’s own data remains more reliable than an extrapolation from market figures.
Idle buffer vs. settlement incident
An idle buffer is the share of liquidity kept available at all times to absorb forecast errors. Its cost is daily, moderate, and measurable: the yield forgone on the funds set aside, plus the unavailability of pledged collateral. A settlement incident has the opposite cost profile: rare, high, and hard to quantify before it happens. The two amounts therefore can’t be compared directly, since one is incurred every day and the other only occasionally. The way to compare them is to express the cost of the incident you fear as the number of days of buffer it would pay for. That conversion puts them in a common unit.
The cost of a funding shortfall breaks down into four consequences that show up at different times, each more expensive than the last. Unsettled payments are returned to the payer at the close and resubmitted the next business day, with a later value date and the corresponding interest. Missed commitments to customers lead to complaints and sometimes contractual penalties. Breaching a throughput criterion or a cap is flagged by the supervisor and by the system operator, both of which document the breach. In extreme cases, a clearing house triggers its default procedure and calls in the defaulting participant’s collateral.
| Tool | What it measures | What it reveals in practice |
|---|---|---|
| Daily maximum intraday liquidity usage | The largest net debit position reached during the day | The real funding need, which the end-of-day position never shows |
| Available intraday liquidity at the start of the day | Own balance, collateralized lines, and assets available to pledge at the start of the day | The headroom the institution has before any inflow |
| Total payments | Gross value sent and received during the day | The scale of activity, the baseline for the other tools |
| Time-specific obligations | Amounts that must be settled at a specific time of day | Rigid points that no queue can absorb |
| Payments made on behalf of correspondent banking customers | The share of flows executed on behalf of client institutions | How much these customers depend on the correspondent’s calendar and capacity |
| Intraday credit lines extended to customers | Capacity granted, and how much is actually used | Risk carried on behalf of third parties, often underestimated |
| Intraday throughput | The share of outgoing value settled by set times of day | Payment delaying behavior, which shifts risk onto the rest of the system |
Settlement capacity is sized on observed peak usage, never on an average. The largest net debit position in a day exceeds the closing balance, often by a wide margin, because inflows and outflows don’t arrive at the same time. A representative observation window includes at least one quarter-end, one long weekend, and one seasonal peak. A shorter window leaves out exactly the days the sizing is meant to cover. BCBS 248 sets out four stress scenarios to apply to this measure: stress at the institution itself, at a major counterparty, at a customer bank, and across the market. Each scenario moves the peak to a different time of day. The counterparty scenario is the most revealing for a participant that relies on a single correspondent.
- Peak intraday usage and the time it occurs, recorded daily and compared with the peak on the same weekday of the previous week.
- Liquidity available at the open, broken down into own balance, collateralized lines, and assets available to pledge that are not yet pledged.
- Share of outgoing value settled by each reference time, a direct measure of payment delaying behavior.
- Instant prefunded balance at the start and end of each closure window, with the number of times it fell below the floor and the number of payments rejected for insufficient balance.
- Unencumbered collateral after haircuts, as distinct from collateral posted, and the time needed to pledge an additional asset.
- Payments queued as the close approaches, by number, by value, and by the age of the oldest order.
- Gap between the expected network position and the reported position, which flags a clearing delay before it becomes an unexpected funding call.
