The Myth of Instant Cross-Border Money Transfers
In FinTech, cross-border money transfers look deceptively simple. To the end user, it’s just a few taps and seconds before money lands in another country. Users now have access to various ways to send money, including bank transfers, debit or credit cards, and direct debit, each offering different speeds and costs. But behind this frictionless user experience is one of the most complex and capital-intensive business models in the financial sector.
SDK.finance, with over 15 years of experience building payment and banking systems across Europe, MENA, Africa, and the Americas, has seen this complexity firsthand. In the money transfer industry, millions of transactions are processed globally every day, reflecting the vast scale and trust in these services. While modern technology can accelerate product development, liquidity, regulatory capital, and compliance remain the true bottlenecks. In this business, software can be licensed or built-but liquidity must be funded.
How cross-border money transfers actually work around the world?
When a customer sends funds abroad, whether through bank transfers or other ways to send money, the money doesn’t actually travel across borders in real time. Instead, money transfer operators rely on a network of local accounts, partner banks, and correspondent institutions that replicate the movement of funds.
The typical process looks like this:
- A user selects the destination country and sends money from Country A.
- The sender provides the receiver’s details and the operator debits the user’s balance, instructing its partner in Country B to pay the recipient immediately – from a pre-funded local account.
- Settlement between the two partners happens later – sometimes hours, sometimes days – through banking networks like SWIFT or other intermediaries.
Customers can send abroad using various ways to send money, such as bank transfers, depending on the destination country and available receive methods.
This model creates the illusion of instant payments. The recipient gets the money fast because it’s already there. But for the FinTech company, it means maintaining liquidity reserves in multiple currencies and jurisdictions. The more corridors and countries supported, the more capital is locked up in idle accounts.
The Liquidity Burden: Pre-Funding and Trapped Capital
Pre-funding is at the heart of the liquidity challenge. Each corridor requires a separate float to guarantee immediate payouts.
Industry data estimates that over $4 trillion globally is trapped in pre-funded accounts to support cross-border flows-capital sitting idle, earning almost nothing.
For a scaling FinTech, this quickly becomes a constraint on growth. Every new market means another local treasury to fund. A business processing $50 million monthly with a conservative 10% liquidity buffer ties up $5 million per corridor. Assuming an 8% cost of capital, that’s $400,000 per year in opportunity cost-per market.
Multiply that across several currencies, and the financial drag becomes evident. The faster you grow, the more working capital you must immobilise. Unlike SaaS, this model doesn’t scale with users-it scales with cash.
Multi-Currency Float and FX Risk
Operating across currencies magnifies the problem. Maintaining balances in USD, EUR, GBP, NGN, or PHP exposes you to FX volatility. If one of those currencies depreciates overnight, your float instantly loses value.
Larger institutions hedge this risk through derivatives-forward contracts or currency swaps – but smaller FinTechs rarely have access to these tools. Many simply overfund accounts to absorb potential losses, which ties up even more capital.
Even where exchange rates are stable, FX spreads, intermediary fees, and conversion costs quietly erode profit margins. Understanding the exchange rate and the impact of currency exchange is crucial when sending money internationally, as unfavorable rates can significantly reduce the amount received by the recipient.
For example, if you send USD and the recipient receives EUR, the exchange rate and currency exchange fees will directly affect the final amount delivered. It is essential to carefully compare exchange rates and transaction fees from different providers before making a transfer, as this difference between gross and net revenue is often the difference between viability and bankruptcy for many money transfer startups.
Are International Money Transfers Ever Truly Instant?
Only a handful of country pairs offer real-time settlement between banking systems. For most corridors, “instant” means instant disbursement, not settlement.
Funds to the recipient are advanced from a pre-funded pool while the sending side settles later. Until the actual settlement completes, the provider bears the liquidity exposure and counterparty risk.
Technologies like ISO 20022 messaging, regional instant payment schemes (like SEPA Instant or the UK’s Faster Payments), and emerging on-demand liquidity models using stablecoins or tokenised cash are shortening this gap. But as of 2025, true cross-border instant payments remain the exception, not the norm.

Regulation: The Price of Trust
While liquidity determines speed, compliance determines survival. In cross-border finance, regulatory oversight is non-negotiable.
To operate legally, payment providers must obtain licences such as:
- Electronic Money Institution (EMI) or Payment Institution (PI) in the EU, which require minimum initial capital of €350,000.
- Money Transmitter Licences (MTL) in the U.S., where each state often demands surety bonds and local reserves.
On top of these, regulators require strict safeguarding of customer funds, meaning client money must be held in ring-fenced accounts-untouchable for operational use.
That’s not the end of it. Each regulator also expects robust KYC (Know Your Customer) and AML (Anti-Money Laundering) frameworks. Failing to maintain them can be ruinously expensive.
In July 2025, Wise (formerly TransferWise) was fined £4.2 million by the UK’s Financial Conduct Authority for AML control failures linked to inadequate monitoring and delayed reporting of suspicious activity.
The fine may seem manageable for an established unicorn, but for a smaller operator, such penalties-or even temporary licence suspension-could be fatal. It highlights that compliance isn’t just paperwork; it’s a structural cost of doing business.
Robust AML processes require investment in:
- Transaction monitoring systems
- Ongoing sanctions screening
- Suspicious activity reporting
- Periodic audits and regulatory communication.
In practice, that means hiring compliance officers, integrating KYC/AML vendors, and maintaining continuous reporting-all of which consume both time and liquidity.
Banking Relationships and Collateral Requirements
Building a payout network also means forming partnerships with local banks (correspondent bank) or payment aggregators. These partners rarely take risk lightly. Most require pre-deposited collateral or minimum account balances as a safeguard.
Each of these micro-balances fragments your liquidity further. Even if you aggregate transactions through a few global partners, those partners themselves maintain local accounts and pass on the cost of capital to you through fees or longer settlement cycles.
The end result: even when your customer sees a one-second transfer, you might have five days of liquidity exposure behind it.
Why Deep Pockets Still Win?
The cross-border payments business rewards those who can fund it. Western Union, MoneyGram, and other incumbents dominate not because of superior technology but because of deep liquidity networks and established correspondent relationships.
Modern entrants can reduce these barriers with:
- Smart routing (matching send and receive flows between corridors),
- Dynamic rebalancing (automatically moving float where demand spikes),
- Access to on-demand liquidity via stablecoins or credit facilities.
But even then, the underlying requirement remains: money must exist somewhere first.
The Role of Money Transfer Technology: Liquidity Efficiency, Not Elimination
SDK.finance provides the infrastructure to make this financial machinery more efficient. Our ledger-based platform, used globally by EMIs, PSPs, and money transfer operators, offers:
- Real-time visibility into balances across corridors
- Automated fund rebalancing via APIs
- Multi-currency support with dynamic FX rate integration
- Pre-built KYC/AML and reporting modules for compliance alignment
- Back-office tools for reconciliation and audit trails.
Technology can’t remove liquidity requirements-but it can help you manage capital smarter, reduce idle float, and maintain control in a multi-currency environment.
Conclusion: The Hard Truth About Cross-Border FinTech
Cross-border money transfers remain one of the hardest corners of FinTech because they sit at the intersection of three worlds: technology, liquidity, and regulation.
Software can move data instantly, but money is slower. It pools in accounts, awaits settlement, and demands compliance oversight at every turn.
For founders, this means success depends on mastering both code and capital. You’ll need a technology backbone strong enough to handle real-time reporting and a financial strategy deep enough to sustain liquidity and compliance.
Modern money transfer platforms compete by offering low fees, transparent fees upfront, and a variety of payment methods – including credit card and debit card options. They emphasize fast delivery time and multiple receive methods such as digital wallet and app-based solutions. Users can track the total amount, transfer fee, and transaction fees before completing a transfer, ensuring transparency.
Some platforms, like the Remitly app or a different app, provide a complete list of features and options for sending money to loved ones, including special offers for the first transfer and the ability to get paid quickly.
With SDK.finance, you can build the former confidently. So you can focus on managing the latter intelligently.
