What Matters
Instant settlement can remove waiting while increasing the cash that must be ready before a payment. Compare identical gross and net obligations, then locate the peak funding requirement by account and time. DN’s calculator separates that funding amount from its financing cost. Netting remains a conditional alternative: its legal scope, timing and credit exposure must be established before the saving becomes executable.
A business can finish the day owing only 5,000 and still need 100,000 at breakfast. The difference comes from the order in which obligations become payable and incoming money becomes usable. For agent commerce, the purchasing question is therefore whether a settlement design fits the cash calendar as well as the transaction.

One currency, one earlier outgoing payment and one later incoming offset. No default probability, collateral, credit lines, taxes, legal advice or multilateral settlement optimisation. A common reserve is added to both designs; differing reserve policies require a separate calendar.
1. Gross payments arrive before the offsets
A payment system can settle each instruction separately or calculate a net position from eligible instructions. Those arrangements ask different funding questions. In gross settlement, the payer must support each outgoing payment when it settles. In net settlement, an offset may reduce the amount ultimately transferred. The BIS discussion of payment innovations explains why settlement design and liquidity-saving mechanisms matter alongside speed.
Consider a hypothetical business that owes a counterparty 100,000 units at 09:00 and expects 95,000 units back at 17:00. If the outgoing transfer must settle first, and no credit is available, the opening funding requirement is 100,000. If the parties can validly defer and net those same obligations at 17:00, the net payment is 5,000. The difference in opening funding is 95,000.
That difference is not a 95,000 expense. At an assumed annual funding rate of 10%, holding the additional amount for eight hours costs about 8.68 units on a simple 365-day basis. The large number is cash capacity; the small number is an illustrative financing charge. Both can matter. A firm might afford the financing charge but lack the credit line needed to produce the cash.
Netting also changes the exposure before settlement. It cannot be assumed merely because two payments appear in a spreadsheet. Record the legal entities, currencies, due times, eligible obligations and agreement permitting the offset. If one payment belongs to a different subsidiary, is disputed, or must reach the recipient earlier, the proposed comparison may not be feasible.
2. Prefunding fragments cash across accounts
Money can exist within the group and still be unavailable to the account that must settle next. A prefunded account, a minimum operating balance and a collateral requirement are different arrangements. Each can reduce the funds available for another obligation, but their ownership, release conditions and financing costs differ.
The Bank of England’s RTGS introduction describes settlement services, including prefunding arrangements for certain retail payment systems. Those arrangements belong to a particular infrastructure and its participants. They do not mean every business using a fast payment service must open an equivalent central-bank account. Similarly, the South African Reserve Bank’s SAMOS description concerns participant settlement and funding arrangements, not a credit facility automatically available to a merchant.
For an agent business, the useful record is simpler: which account owns the usable balance, who can move it, how much must remain, and when a transfer becomes effective? A 20,000 account balance with a required 5,000 operating floor provides 15,000 of headroom under that policy. Counting all 20,000 as available overstates capacity.
Five separate 10,000 buffers tie up 50,000. That may be an intentional resilience choice. It may also be an accidental consequence of separately configured agents. Consolidation should follow permitted ownership and access boundaries. The objective is to price the value of each buffer, including its failure protection, rather than treating every idle balance as an error.
3. Round-the-clock execution can require earlier funding
A payment may be available to its recipient immediately while the underlying transfer between payment-service providers follows a different process. The BIS analysis of payment speed distinguishes these layers. A buyer should therefore ask about the time at which funds become usable for the next obligation, not infer every settlement detail from an instant-payment label.
For each route, record three clocks: when the agent may initiate a payment, when the recipient can use the money, and when the payer can replenish the relevant balance. Add the timezone and operating calendar. The route may execute throughout a weekend while its ordinary replenishment source depends on another institution’s schedule.
Imagine a hypothetical weekend service requiring a 30,000 buffer to be funded on Friday. The economic holding period begins when that cash stops being available for other purposes. It does not begin only when the first Saturday transaction executes. Conversely, incoming weekend payments that can be reused may reduce the peak requirement.
This is why a single average settlement time is insufficient. Two routes with the same average can have different peaks because their largest outgoing obligations occur at different times. The DN calculator isolates one outgoing-before-incoming comparison. A complete operating decision needs a dated cash calendar, with event order preserved and replenishment assumptions checked against the actual account arrangements.
4. The refund clock continues after settlement
Settlement completes a payment event. It does not establish that delivery, acceptance, cancellation or a later refund has finished. An agent that spends every incoming unit as soon as it becomes available may leave the business unable to meet a later commercial obligation.
Suppose a seller must return 20,000 to customers tomorrow while the related supplier recovery is expected next month. Those dates create a funding gap even if the original sale settled instantly. A future service credit cannot fill tomorrow’s cash payment unless the creditor accepts it and the applicable terms permit that use. The relevant record links the customer obligation to its supplier recovery without assuming they share a due date or remedy.
A reserve should also be counted once. The same 10,000 cannot simultaneously cover a network operating floor, a refund scenario and a payment due elsewhere unless the timing and stress assumptions allow its reuse. Label shared resources so that a stress scenario can expose conflicting claims.
Delayed net settlement can create its own credit and operational exposures. A lower opening cash requirement is not proof of a better arrangement. Compare the funding saved with the protection, guarantees, collateral, delay tolerance and failure consequences of the actual design. This article quantifies one liquidity difference; it does not convert that difference into a universal preference for deferred payment.
5. Compare feasible designs for the same obligation
Begin with the obligation before comparing rails. Hold the amount, currency, payer, recipient and required availability time constant. Then specify whether each candidate can actually meet those conditions. A cheap or cash-efficient route that misses the contractual deadline is not an equivalent offer.
| Claim | Evidence to retain | Decision output |
|---|---|---|
| Payments can be offset | Applicable agreement, parties and eligible obligations | Feasible netting comparison or unresolved assumption |
| Balance is available | Account, currency, ownership, reserve and release rules | Usable funding at the deadline |
| Incoming cash reduces the peak | Confirmed or scenario-based receipt time | Peak cumulative deficit |
| Faster payment saves money | Whose funding rate and whose holding period | Financing effect separated from fees |
The DN Prefunding-vs-Netting Calculator asks for one outgoing payment, a later incoming offset, the gap in hours and a common reserve. It reports gross funding, hypothetical net funding, the difference and its simple financing cost. The netting field records the operator’s evidence status. Selecting “documented” does not independently verify enforceability.
Change the incoming amount, move its arrival later and increase the reserve. Those sensitivities show what the result depends on. If an incoming payment is uncertain, show a no-receipt case as well. If the business already has an agreed credit line, add its actual availability and conditions to the broader cash calendar; do not treat a theoretical borrowing capacity as funded cash.
The next action is a bounded review of one payment route and its next material obligations. A useful outcome is a documented funding requirement and one unresolved constraint with an owner. A broad claim that a system is faster is much less useful than knowing the amount that must be available in a named account at a named time.
Methodology, limitations and corrections
Methodology. All numerical scenarios are hypothetical. Gross opening funding equals the earlier outgoing amount plus the shared reserve. Hypothetical net funding equals the larger of zero and outgoing minus incoming, plus that reserve. Additional funding is the difference. Simple financing cost equals additional funding × annual rate × hours ÷8,760. For 100,000 outgoing,95,000 incoming, eight hours and 10%, this yields 95,000 additional funding and 8.675799 financing units. The model assumes the net design may defer eligible obligations until the later event; it does not establish that permission. Numbers are nominal and use one currency.

Frequently asked questions
Does instant settlement always require more cash?
No. Earlier incoming receipts, balance reuse and available funding facilities can lower the requirement. The relevant result is the peak deficit in the actual event order.
Can two businesses automatically net opposite payments?
The calculator does not establish that right. Parties, eligible obligations, currencies, timing and applicable agreements must support the proposed offset.
Is additional funding the same as a loss?
No. Funding is cash capacity. Financing expense, fees and losses are separate quantities.
Can the calculator combine currencies?
No. Convert neither currency nor timing silently. Build a separate route and cash calendar for each obligation, including actual conversion and transfer conditions.
