How Cross-Border Payouts Trap Working Capital

Consider a company that pays suppliers in Manila every business day. Its bank balance is healthy and its accounts show more than enough to cover the day's file. The file still fails on a Friday afternoon, and the reason has nothing to do with solvency. The money it holds is in the wrong currency, in the wrong jurisdiction, at an institution that cannot reach the receiving rail before that rail closes for the weekend.

The question that matters for a company in that position is not what each transfer costs. It is how much cash must sit permanently in places it cannot otherwise use so that a payout of, say, $100,000 a day arrives on time. That parked cash is the largest and least visible line in cross-border payout economics. It appears on no invoice. It carries an interest cost. It is sized by a settlement calendar rather than by a fee schedule. And a stablecoin settlement leg does not remove it — it moves it somewhere else.

Prefunding is a design requirement

Prefunding means value must already sit at the endpoint before an instruction can be executed there. It is a property of how the rails settle, not a preference banks could waive.

The Philippine case is explicit. InstaPay runs in real time, around the clock, and settles through PhilPaSS against prefunded demand deposit accounts that participants hold at the Bangko Sentral ng Pilipinas (BSP InstaPay FAQ). Real-time credit to a beneficiary is possible precisely because someone has already funded the settlement account. Direct access to the domestic rails requires a BSP-licensed bank or electronic money issuer holding such an account. Everyone else enters through sponsored or indirect clearing (BSP PhilPaSS overview).

The same constraint reappears one layer up, on the stablecoin side. The Bank for International Settlements describes stablecoin issuance as imposing a cash-in-advance constraint, with full payment upfront before tokens exist, and reports only anecdotal evidence of lower costs in some corridors (BIS Annual Economic Report 2025, Chapter III). Holding a token inventory in order to settle faster is prefunding denominated in a different asset.

Trapped liquidity is a named cost driver in the wholesale literature. Oliver Wyman and J.P. Morgan modelled roughly $23.5 trillion in annual corporate cross-border flows carrying more than $120 billion in transaction costs excluding FX, with trapped liquidity among the drivers (Oliver Wyman and J.P. Morgan, November 2021). Those are 2021 model outputs. The widely repeated figure of $4 trillion trapped in prefunded accounts has no published methodology and is not used here.

A healthy balance is not necessarily usable

A treasury lead needs four conditions satisfied at once: the correct currency, in the correct account, in the correct jurisdiction, reachable by the correct payout system. If any one of them fails, the balance is unusable for that day's file.

Currency is the obvious constraint. Jurisdiction is the binding one. Delivering pesos to a Philippine beneficiary requires a BSP-supervised institution: a bank, an electronic money issuer under BSP Circular 1166, a remittance and transfer company or money service business under Circular 942, or a virtual asset service provider under Circular 1108 for the virtual-asset-to-fiat leg. Registration as an operator of payment systems under Republic Act 11127 and BSP Circular 1049 is a registration rather than a funds-handling licence, so an orchestrator without a licence still needs a licensed partner to touch money.

That partner set is closed by policy. The BSP has continued its moratorium on issuing new VASP licences from 1 September 2025, subject to reassessment based on global and local developments, under Monetary Board Resolution No. 848 (BSP Memorandum M-2025-031).

The consequence is that endpoint liquidity cannot be treated as a procurement problem. A company whose delivering partner runs short of capacity cannot simply onboard a second licensed provider in a week, because the licence pool is not currently being added to. Capacity has to be bought in advance, with cash.

The settlement calendar sets the number

Prefunding days are a function of operating hours rather than of technology.

On the funding side, Fedwire operates from 9:00 p.m. Eastern the prior day to 7:00 p.m. Eastern, on business days only (Federal Reserve Financial Services). A November 2025 Federal Register action expands those hours, and anyone modelling weekend behaviour should work from that document directly.

On the delivery side, the two Philippine rails behave differently. InstaPay is real time and runs around the clock, with a ₱50,000 standard cap; InstaPay for Business raised that cap to ₱500,000 for registered businesses from 29 July 2026 (Manila Bulletin). PESONet is batch-based, has no scheme cap, runs three daily settlement cycles with cutoffs at 10:00 a.m., 1:00 p.m. and 4:00 p.m., and operates on banking days only (BSP PESONet 3MBS FAQ).

Ticket size therefore selects the calendar, which is why it belongs in any model of this corridor. A ₱620,000 payout exceeds the InstaPay business cap and routes to PESONet, which means banking days and a cutoff. A 4:00 p.m. cutoff missed on a Friday before a Philippine holiday turns one day of float into four. Prefunding is sized by the worst case in that calendar, not by the average.

The wire route carries its own lag, and it sits at the end of the chain. SWIFT-reported data indicates that 89% of payments reach the recipient bank within an hour while only 60% of wholesale payments reach customer accounts in that window, per European Payments Initiative reporting in August 2023. The figure is self-reported and now dated, but it locates the delay at the beneficiary leg, which is the leg a stablecoin settlement layer does not touch.

Institutional expectations have been revised downward. The Financial Stability Board stated in October 2025 that it is unlikely that satisfactory improvements at the global level will be achieved in line with the 2027 roadmap timetable (FSB Consolidated Progress Report 2025). Treasury planning should assume today's calendar persists.

The FX window is the prefunding window

Conversion from dollars to pesos happens exactly once on either route. Only the venue moves. What prefunding days change is how long the company holds an unconverted or pre-converted balance against a fixed obligation.

Inward FX to the Philippines requires no prior BSP approval, conversion is at the recipient's option, and banks apply their own KYC (BSP FX regulations FAQ). Bank FX markups are commonly cited at 1–3% over mid-market, with intermediary lifting fees of roughly $15–50 each deducted from principal. That range comes from Corpay, a bank competitor, in June 2026. Bank of America describes the mechanism plainly: FX-denominated wires carry no fee, but markups associated with the currency conversion are included in the exchange rate.

A company prefunding three days ahead is running a three-day rolling FX position against a peso obligation, whether or not it accounts for it as one. Hedging that position is a cost not modelled below, because no dated source in the record prices it for this corridor.

Worked example: an illustrative $100,000 per day into the Philippines

All figures are illustrative unless a dated source is named. The FX anchor is 1 USD = 62.36 PHP, the rate at time of access on 1 September 2026; restate the BSP reference rate at publication. The example assumes average ticket sizes above the InstaPay business cap, so PESONet governs the delivery calendar.

Formulas:

• Trapped capital = average daily payout volume × prefunding days + operating buffer
• Annual carrying cost = total capital at rest × annual cost of capital
• Exception reserve = average daily payout volume × failure rate × recycle days

Assumptions: operating buffer 25% of the prefunded base; annual cost of capital 12%; failure rate 1.5%, recycling over 5 days on the conventional route and 7 on the stablecoin route; 250 banking days a

State 1 takes its three prefunding days from the calendar above. A Thursday funding instruction clears Fedwire on a business day; the file misses the Friday 4:00 p.m. PESONet cutoff; Saturday and Sunday are not banking days; the beneficiary is credited on Monday or later, with the wire route running to T+2 or beyond.

State 2 compresses the settlement leg without touching either edge. On-chain finality is short: approximately 15 minutes on Ethereum, per ethereum.org, and on Base roughly 2 seconds to L2 inclusion with about 20 minutes to full L1 finality (Base documentation). One day of prefunding survives anyway, because the PESONet cutoff calendar is indifferent to how funds arrived, and because peso float must already sit onshore at a licensed endpoint. The consolidation is real: a provider model in production for over a year describes a single USDC balance replacing multiple prefunded accounts, converting on payout (Thunes). That is a vendor account, and it describes a treasury consolidation rather than an elimination.

The exception reserve moves the wrong way on the faster route. On-chain legs are irreversible while fiat legs are not, so a returned peso credit has no automatic reversal upstream. Recycle days should therefore lengthen on the stablecoin route rather than shorten, which is why State 2 carries a larger reserve than State 1 despite holding less capital overall.

State 3 is the case most models leave out. Off-ramp capacity falls to 60% of daily need, leaving a shortfall of $40,000 a day. To keep beneficiaries paid on schedule the company must hold the accumulating backlog on top of the day's file, so after ten business days of constraint the backlog reaches $400,000 — four days of volume, and four effective prefunding days. At that point the faster route immobilises more capital than the conventional one it replaced.

The triggers for this state are documented rather than hypothetical. Solana's block finalisation halted for five hours on 6 February 2024 (Solana Foundation outage report). USDC traded at roughly $0.87–0.88, about 12% below parity, on 11 March 2023 after disclosure of $3.3 billion of reserves at Silicon Valley Bank (CNBC). Redemption is conditional: Circle commits to redeem 1 USDC for 1 USD subject to its terms, applicable law and any fees, and only Circle Mint account holders may redeem directly (Circle USDC Terms, December 2025). Tether's published direct-redemption terms carry a $150 verification fee, a $100,000 minimum, a fee of the greater of $1,000 or 0.1%, and processing over several days (Tether fees). The International Monetary Fund notes that major stablecoin issuers do not provide redemption rights to all holders under all circumstances (IMF, Understanding Stablecoins).

Carrying cost and transfer fees are different instruments

A transfer fee is charged per transaction. It is quoted, invoiced and negotiable. A carrying cost accrues per day of balance. It is unquoted, booked as interest or opportunity cost, and set by settlement calendars and licensing capacity rather than by a commercial conversation.

At the volumes in the example, the fee line is the larger of the two by a wide margin. Annual throughput of $25 million against the cited 1–3% FX markup is $250,000 to $750,000 a year, while State 1 carrying cost is $45,900. The spread runs to 100–300 basis points; the carry is 18.4. A treasurer looking for the biggest number should start with the conversion spread.

The reason to measure carrying cost anyway is that the two lines behave differently under pressure. Fee lines compress under negotiation at volume, and the FX markup compresses most. Carrying cost does not, because no counterparty can sell shorter banking days. It falls only when prefunding days are removed or the float moves onto someone else's balance sheet — and when a partner holds the endpoint float, its carry is priced into the conversion spread rather than eliminated. The dollar-to-peso conversion spread at Philippine VASPs is not published by any provider, which makes it the least verifiable line in the corridor and the place where a carry that has been moved becomes hard to see.

Carrying cost also moves the wrong way in exactly the scenario a fee comparison cannot detect. In State 3 it rises by a third while the transfer fees stay where they were.

Who owns each function

A payout corridor has five distinct owners, and confusion between them is where capital gets stranded.

• Treasury owns float sizing, prefunding days, the buffer percentage and the FX exposure window.
• Payment operations owns the cutoff calendar at both edges, holiday tables, the exception queue and the returns runbook.
• Compliance owns the regulated functions. In the United States: FinCEN money services business registration, state money transmitter licensing and OFAC screening. In the Philippines: BSP licensing of the delivering entity, the BSP Travel Rule requiring originator and beneficiary information on virtual asset transfers of ₱50,000 or more, and Anti-Money Laundering Council reporting for covered transactions above ₱500,000 within one banking day. The GENIUS Act was enacted in the United States on 18 July 2025 and remains at proposed-rule stage, effective on the earlier of 18 January 2027 or 120 days after final rules (Congress.gov). The Committee on Payments and Market Infrastructures and IOSCO have stated that a stablecoin arrangement performing a transfer function is a financial market infrastructure, with settlement-finality guidance applying (CPMI-IOSCO).
• Product owns the delivery promise, and settlement is not the same thing as delivery. Stripe's stablecoin payouts, in private preview, terminate in USDC in a wallet, cover US platforms and individuals or sole proprietors only, and list the Philippines without PHP fiat termination (Stripe documentation). Tokens in a wallet are not funds available to the recipient.
• Finance owns the carry accounting and reconciliation. The stablecoin route adds a ledger, with a funding leg, a chain leg, a conversion leg and a payout leg.

Federal Reserve researchers reached the same boundary from the other direction, finding that a stablecoin transfer removes correspondent intermediation while on-ramp and off-ramp costs, FX conversion and AML/CFT compliance persist (Federal Reserve FEDS Note, 30 March 2026).

A worksheet for your own corridor

Fill this in per corridor and per provider, using the worst case in the calendar rather than the average.

Three questions worth asking before signing. Which licensed entity credits the beneficiary, and under which licence? Is the endpoint float prefunded or converted just in time, and who carries it? What happens, step by step, when the beneficiary account is closed?

Implications

A payout corridor is best treated as a balance-sheet decision that a payment rail executes. The number to manage is prefunding days, and the lever that moves it is the calendar at the fiat endpoints rather than the speed of the settlement leg.

Three things follow.

First, the case for a stablecoin settlement leg is treasury consolidation rather than faster customer-facing payment. In the illustrative model, removing two prefunding days releases about $247,000 of capital and roughly 12 basis points of annual carrying cost, while the beneficiary's credit timing stays governed by PESONet cutoffs. That is a real saving, and it is smaller than the conversion spread on the same volume, which is worth knowing before a corridor migration is justified on treasury grounds alone.

Second, the saving holds only where compliant fiat conversion and reliable local payout liquidity both exist. Where the licensed endpoint set is closed, as it currently is in the Philippines under the BSP's continuing VASP moratorium, endpoint liquidity becomes the binding constraint, and the constrained state immobilises more capital than the route it replaced.

Third, procurement should be scoped to both lines. A comparison that ranks providers on fees per transaction is looking at the larger cost but only one of them, and it will not detect the carry that a partner has absorbed and repriced into a spread it does not publish.

The Philippines is one corridor with one licensing regime and one rail calendar. None of this transfers to another market without rebuilding the calendar and the licensing map from that market's own regulator.
