FX, Prefunding and Working Capital: The Hidden Cost of Scaling Remittance Corridors
How FX costs, prefunding and settlement delays tie up working capital across remittance corridors, and how modern payment infrastructure can improve liquidity.
Opening a new remittance corridor may look like a straightforward growth decision, but underneath it is also a liquidity decision. Entering another payout market can mean sourcing an additional currency, maintaining local liquidity, managing a new FX route and ensuring enough capital is available in the destination market to keep recipients paid, even when the corresponding funds have not yet settled.
For one corridor, that capital requirement may be relatively manageable. As a remittance company expands across ten, twenty or fifty corridors, however, the economics begin to change. More markets can mean more liquidity distributed across different accounts, currencies and payout partners, with an increasing amount of working capital committed simply to keeping those corridors operational.
This is where FX, prefunding and settlement become closely connected. Although they are often discussed as separate parts of the payment process, together they determine one of the most important questions for a remittance provider: how much capital does this corridor require to operate reliably? The answer can directly affect working capital, margins and the speed at which a remittance company can expand into new markets.
What is prefunding in remittances?
Prefunding means placing liquidity in a destination market before it is needed for payout. Imagine a remittance company collects €500 from a sender in Spain for a recipient in Colombia. The sender expects the recipient to receive Colombian pesos quickly, but if the underlying international settlement process takes a day or more, the remittance provider cannot necessarily wait for those funds to arrive before paying the recipient. Instead, it may hold Colombian pesos, or another form of available liquidity, with its payout partner in advance.
That buffer helps keep payouts moving, but it also ties up capital. The Bank for International Settlements (BIS) describes this trade-off directly: in cross-border and multi-currency payment systems, liquidity is often managed through prefunding because access to liquidity during the settlement process may be more limited than it is in domestic payments. Prefunding reduces the risk of delays or failed payments, but it can also leave capital sitting unused in reserve.
For a remittance company, the issue becomes more significant as the number of payout markets grows. Each corridor may require its own liquidity buffer, while every market can have different settlement times, currencies, banking relationships, operating hours and expected transaction volumes. As a result, growth can create a second balance sheet behind the customer-facing product: the liquidity that has to be positioned across the network simply to keep payments flowing.
Why does settlement speed affect working capital?
The amount of liquidity a remittance provider needs is closely linked to how quickly and how predictably money moves between collection and payout. The longer the gap between the two, the greater the buffer a business may need to protect against delays.
If settlement is expected to take two days but occasionally stretches to four, the business cannot manage liquidity around the average alone. It needs enough capital available to keep payouts running during periods when incoming funds have not yet arrived. For finance teams, a predictable settlement time can be as important as a fast one.
The Bank of England has highlighted the connection between settlement hours, prefunding and liquidity costs. It notes that while prefunding can reduce settlement risk, it requires firms to keep capital set aside, while more frequent settlement can allow that capital to be used more efficiently and reduce prefunding costs.
The opportunity cost can be meaningful. As a purely illustrative example, if a remittance network has €10 million positioned across payout markets and that capital could otherwise generate an annual return of 5%, the theoretical opportunity cost would be around €500,000 per year. That does not mean every euro held in a payout account would otherwise earn 5%, nor that prefunding can be eliminated altogether. It simply illustrates an important point: liquidity carries a cost even when that cost does not appear as a separate charge. The capital is unavailable for something else.
Where FX enters the equation
Prefunding is only one side of corridor economics, the other is foreign exchange. Most remittance corridors involve two currencies, which means that somewhere between collection and payout the sending currency has to become the currency the recipient receives, and that conversion comes at a cost.
According to the Financial Stability Board’s 2025 monitoring of cross-border payments, FX remained the largest component of overall retail cross-border payment costs. The FSB also found that FX margins could remain significant even where payment fees themselves had decreased. For a remittance provider processing thousands of transactions, relatively small differences in FX pricing can therefore have a substantial impact at scale.
A business might spend time negotiating a few basis points off a transfer fee while overlooking a much larger cost embedded in the exchange rate. That is why the more useful question is not simply, “What does the transfer cost?” but rather, “What is the total cost of converting and delivering the destination currency?” That total can include the exchange rate, the FX spread, payment or settlement fees, intermediary costs, payout costs and the cost of maintaining liquidity while the payment settles.
What happens when a corridor requires more than one FX conversion?
In some cross-border payment routes, two currencies may not be exchanged directly, which means a third or vehicle currency, often a major currency such as the US dollar, can sit in the middle. Instead of a direct route such as EUR → destination currency, the payment may effectively follow EUR → USD → destination currency.
The BIS notes that vehicle currencies can be required where a third currency is needed to facilitate the exchange. Its Project Rialto work has specifically explored ways to improve FX and settlement for retail cross-border payments, including transactions that require a vehicle currency. That does not automatically mean a payment will be expensive, but each additional conversion creates another point where an FX spread may be introduced, liquidity must be sourced, settlement has to take place and operational complexity can increase. For high-volume remittance businesses, this is why FX architecture can matter almost as much as FX pricing.
The cheapest-looking quote is not necessarily the cheapest route if the underlying settlement model requires additional conversions or large prefunded balances. The real cost of a corridor is bigger than its transaction fee, and this changes the way a remittance company should evaluate a payment corridor.
Imagine two different routes. Corridor A offers a low transaction fee, but settlement is unpredictable, large balances must be prefunded, FX pricing is difficult to benchmark and liquidity cannot easily be moved between markets. Corridor B may have a slightly higher visible transaction fee, but settlement is faster and more predictable, FX pricing is transparent upfront, less capital needs to remain positioned and liquidity can be redeployed more quickly. Looking only at the transfer fee could make Corridor A appear cheaper. Looking at working capital requirements and total corridor economics may tell a very different story.
For a COO or CFO at a remittance company, the useful metrics therefore extend well beyond cost per transaction. It is worth asking how much liquidity each corridor requires, how often that balance turns over, how predictable settlement is, what the true FX cost looks like, how much capital sits unused during quieter periods and how quickly liquidity can be moved when demand shifts. That is the difference between evaluating a payment provider and evaluating the underlying payment infrastructure.
Why corridor growth can amplify the problem
Remittance businesses rarely grow evenly across every market. One week, demand may spike in Mexico, and the next, a holiday or payroll cycle may increase volume into Colombia. A new migration pattern, seasonal event or marketing campaign can create an unexpected increase in another payout market. If liquidity is fragmented across separate accounts and payout partners, the capital does not always sit where demand appears. A business can therefore have substantial cash across its network while still experiencing a liquidity shortage in a particular corridor.
This is one of the unusual realities of prefunding: having enough money overall does not necessarily mean having enough money in the right place at the right time. As the number of corridors grows, treasury teams have to forecast demand, monitor balances and move liquidity between markets. The operational burden therefore increases alongside the financial one.
How faster settlement changes the economics
Faster settlement does not automatically eliminate the need for prefunding. It can, however, reduce the time between collecting funds and making them available for payout, which may reduce the size of the liquidity buffer required to bridge that gap.
Imagine a corridor processing €1 million per day. If the infrastructure requires enough liquidity to cover several days of settlement exposure, the business may need to position several million euros, or the equivalent in local currency, simply to keep payments flowing. If settlement becomes faster and more predictable, the same capital can potentially turn over more frequently.
Instead of a cycle that looks like fund → wait → replenish → wait, it can move closer to fund → settle → reuse. That is what liquidity efficiency really means. It does not necessarily mean holding no reserve at all; it means making each euro of reserve work harder.
Why “always on” matters, but only where the full route supports it
Modern payment infrastructure increasingly operates beyond traditional banking hours, which matters because cross-border payments are not limited to 09:00-17:00 from Monday to Friday. Remittance customers send money at night, on weekends and across time zones.
Traditional settlement windows can create a gap between the moment a payment is initiated and the point at which the underlying liquidity can actually move. The Bank of England is itself working towards near-24/7 settlement for parts of UK payment infrastructure and has cited cross-border payments and more efficient liquidity management as important reasons for extending operating hours.
However, “24/7” needs context. A payment is only as always-on as the full route supporting it. If the settlement layer operates continuously but the final local payout rail closes for the weekend, the recipient may still have to wait. For a remittance provider, the better question is therefore not simply whether a provider offers 24/7 payments, but which parts of the corridor are genuinely available around the clock, and where cut-off times still apply.
FX transparency matters to the remittance business and the customer
FX is not only a treasury issue. Ultimately, it helps determine how much money reaches the recipient. The World Bank’s Remittance Prices Worldwide database defines total remittance cost as including both the explicit transfer fee and the exchange-rate margin: the difference between the market reference rate and the rate applied to the transaction. Two providers can therefore advertise similar fees while delivering different amounts to the beneficiary because the exchange rates they apply differ.
For the remittance company, transparent FX pricing makes the economics of each corridor easier to understand. For the sender, it makes the overall proposition easier to evaluate and trust. For the recipient, it can directly affect the value that ultimately arrives.
What should remittance companies measure?
If working capital matters, treasury teams need to look beyond transaction volume alone. A useful corridor review should consider the amount of prefunded capital positioned in each market, how frequently that balance is used and replenished, the average and variability of settlement times, and the effective FX spread applied to transactions.
It is also useful to understand the conversion path behind each corridor. Is the currency exchanged directly, or does the route require another currency in between? How much prefunded capital routinely sits unused? How often do failed or delayed payments require additional liquidity or manual intervention? And once FX, settlement, liquidity and operational costs are taken into account, what does the corridor actually contribute to profitability?
Looking at these measures together gives a far more complete picture of corridor performance than simply counting the number of transactions processed.
How VirtuaBroker approaches FX, settlement and liquidity
VirtuaBroker provides cross-border payment infrastructure for remittance companies, fintechs and payment providers operating across multiple markets. Rather than building a separate banking and payment setup for every corridor, businesses can connect to VirtuaBroker through a single integration and use supported routes for collection, FX, settlement and payout.
The objective is to reduce unnecessary friction between money being collected in one market and becoming available in another. Depending on the supported corridor and setup, that can include faster settlement, transparent FX and payment costs, access to local payment rails, improved visibility throughout the payment journey and infrastructure that supports expansion into additional corridors without rebuilding the entire payment stack each time.
Where settlement becomes faster and more predictable, remittance businesses may also be able to reduce the liquidity buffers required to keep payouts moving. The benefit, therefore, is not simply a faster payment. It is the possibility of using working capital more efficiently.

What is cross-border settlement and why does it matter for remittance companies?
What is VirtuaBroker? Cross-border payments explained.
Estimates of how much money sits globally in prefunded payment accounts vary enormously. That may make for an eye-catching headline, but operationally it is not the most useful figure for an individual remittance company. How much capital is currently positioned across payout markets? How much of that liquidity is genuinely needed? How quickly can it be replenished? What would change if settlement became faster or more predictable? And when the business enters another corridor, how much additional working capital will that expansion require? These questions turn prefunding from an accepted operational cost into something that can be measured, challenged and potentially improved.
The goal is not simply to move money faster. It is to build a payment operation where FX, settlement and liquidity work together, so that international growth does not require an ever-larger amount of capital sitting idle across multiple markets.
If prefunding, FX costs or settlement delays are limiting the corridors you can serve, talk to the VirtuaBroker team about your current payment flow and expansion plans.
Frequently asked questions
What is prefunding in remittance payments?
Prefunding means placing money with a payout partner or in a destination market before customer payments have fully settled. It allows recipients to be paid while the underlying cross-border settlement process is still being completed.
Why does prefunding tie up working capital?
Funds held in prefunded accounts cannot be freely deployed elsewhere in the business while they are needed to support payouts. As a remittance company expands across more corridors, the combined liquidity buffer can result in a significant amount of working capital remaining idle.
Can faster settlement eliminate prefunding?
Not necessarily. Liquidity requirements depend on the corridor, payout model, transaction volumes, risk management approach and underlying payment infrastructure. Faster and more predictable settlement can, however, reduce the size of the buffer required in some models.
How does FX affect remittance profitability?
FX costs can include the spread between the market reference rate and the exchange rate used for the actual conversion. At high transaction volumes, even relatively small differences in FX pricing can have a meaningful impact on the economics of a corridor.
What is a double FX conversion?
Some payment routes use a third, or “vehicle”, currency when direct liquidity between the sending and destination currencies is limited. In practice, this can mean converting the original currency into the vehicle currency before converting it again into the final destination currency.
What should a remittance company compare between settlement providers?
The comparison should go beyond the headline transaction fee. Settlement speed and predictability, FX pricing, prefunding requirements, corridor coverage, payment visibility, exception handling, operating hours and the total amount of capital required to support the flow all affect the real economics of the infrastructure.
