Last-Mile Payment

What Is a Last-Mile Payment?

A last-mile payment is the final stage of a financial transaction where funds are delivered to the end recipient. The term is borrowed from telecommunications and logistics, where "last mile" describes the final, most difficult leg of delivery. In payments, it refers to the gap between money arriving at a destination country's financial system and that money being credited, cashed out, or otherwise made available to the intended recipient.

Whether the transaction is a migrant worker sending earnings home through a remittance corridor, a business paying a freelancer abroad, or a humanitarian organization disbursing aid funds, the success of the entire payment chain depends on the reliability of this final delivery step. Roughly 80% of a cross-border payment's journey time occurs after it leaves the correspondent banking network: in the last mile at the beneficiary bank, mobile wallet, or payout point.

How It Works

A cross-border payment typically moves through three stages before reaching the recipient. Understanding where the last mile fits helps explain why it is the most expensive and fragile part of the chain.

1. Origination: the sender initiates the transfer through a bank, money transfer operator, or digital app. Funds are debited from their account in the sending currency.
2. Intermediary settlement: the payment routes through correspondent banks, clearing networks (such as SWIFT), or newer rails like stablecoin payment rails. Currency conversion may happen at this stage.
3. Last-mile delivery: funds arrive at the destination country's financial system and must be converted to local currency, then delivered to the recipient through a bank deposit, mobile money credit, cash pickup at an agent location, or direct wallet transfer.

Why the Last Mile Is the Hardest

Several factors make last-mile delivery disproportionately expensive and complex:

• FX conversion markups: traditional banks quote rates 2-5% worse than the mid-market rate, while fintechs typically mark up 0.5-1.5%
• Fragmented infrastructure: each destination country has different payment methods, banking systems, and mobile money platforms, requiring separate integrations
• Agent liquidity constraints: physical agents in rural areas may lack sufficient cash for withdrawals or float for deposits, disrupting service
• Compliance overhead: KYC/AML verification at the payout end increases operational costs and processing time
• Geographic reach: delivering to recipients in remote areas without banking infrastructure requires physical agent networks or alternative digital rails

The cumulative effect is significant: cross-border inefficiencies consume roughly 5-7% of transaction value overall. The transfer fee is often the smallest cost layer, with FX markup, intermediary charges, compliance overhead, and integration costs quietly multiplying until the true cost per payment is 2-5x the headline rate.

Last-Mile Delivery Methods

The method used for last-mile payout depends on the recipient's location, access to banking, and local infrastructure:

Real-World Examples

M-Pesa in Kenya

Launched by Safaricom in 2007, M-Pesa is the world's pioneering mobile money service and one of the most successful last-mile payment networks ever built. It operates through a hub-and-spoke agent model where super-agents distribute liquidity to over 287,000 sub-agents: small shops, kiosks, and businesses authorized to handle cash deposits and withdrawals. Over 90% of remittances in Kenya are now received via mobile money, and M-Pesa has been credited with lifting 194,000 households out of poverty by providing financial inclusion to those without bank accounts.

GCash in the Philippines

GCash is the leading mobile wallet in the Philippines, with approximately 81% of Filipinos owning an account. Thousands of GCash agents serve as cash-in/cash-out points across the country, and the platform partners with Western Union, Remitly, Ria, and WorldRemit for inbound remittance delivery. This integration means a migrant worker in the United States can send money that arrives in a recipient's GCash wallet within seconds, or can be withdrawn as cash at any of thousands of agent locations.

Stablecoin-Powered Last-Mile Rails

A growing number of companies are using stablecoin payment rails to solve the last-mile problem. Stablecoin payment volume reached $390 billion in 2025, more than double 2024 levels, with B2B payments growing 733% year-over-year. Several approaches are emerging:

• Western Union launched USDPT on Solana in May 2026, connecting its stablecoin to 380,000 active agent locations across 200+ countries: the first stablecoin where the issuer's existing distribution network serves as both on-ramp and off-ramp
• Onafriq, Africa's largest payments gateway, integrated USDC across 40+ African markets in partnership with Circle, bridging stablecoin settlement with local mobile money payout
• Nium partnered with Circle in May 2026 to connect stablecoin settlement with last-mile payouts across 190+ countries
• Stripe acquired Bridge.xyz for $1.1 billion, building stablecoin orchestration APIs that handle FX conversion between fiat and USDC for cross-border payouts

Why It Matters

Global remittance flows to low- and middle-income countries reached $669 billion in 2025 and are projected to cross $900 billion in 2026. According to the World Bank, the global average cost of sending $200 stood at 6.36% in Q3 2025: more than double the UN Sustainable Development Goal target of 3%. Banks remain the most expensive channel at 9.50% on average, while digital providers have brought costs down to 3.65%.

The last mile accounts for a large share of these costs. Even when stablecoin transfers cost well under 1%, FX conversion, local payout fees, mobile money charges, and compliance overhead at the destination can push end-to-end costs back toward 7-8% in many African corridors. Solving the last-mile problem is essential to meeting SDG targets and ensuring that more of every dollar sent actually reaches the recipient.

Two billion people worldwide remain unbanked, and for them the last mile is not just expensive: it may not exist at all. Mobile money has reached over two billion registered accounts globally, with $2 trillion in transactions in 2025 (doubling since 2021). In Sub-Saharan Africa alone, $1.4 trillion flowed through mobile money in 2025. These networks have become the de facto last-mile payment infrastructure in regions where traditional banking rails do not reach.

Bitcoin L2s as Last-Mile Infrastructure

Bitcoin Layer 2 networks and stablecoin wallets are emerging as an alternative last-mile rail, particularly in regions with limited banking infrastructure but growing smartphone penetration. Rather than relying on correspondent banks or physical agent networks, these systems enable peer-to-peer value transfer that settles in seconds.

Spark, a Bitcoin Layer 2 built on statechains, addresses the last mile by enabling instant, low-cost payments without requiring users to operate Lightning nodes or manage channels. With native stablecoin support through USDB, Spark provides dollar-denominated savings and transactional capability in a single self-custodial wallet: a combination that serves both as a store of value and a last-mile payment tool.

The Lightning Network has also expanded its reach, with stablecoins arriving via Taproot Assets in 2026. For users in high-inflation economies, a dollar-denominated stablecoin that settles in seconds for a fraction of a cent is a compelling alternative to traditional money transfer operators that charge 5-10% per transaction.

Risks and Considerations

Persistent Cost Gap

While new technologies have reduced intermediary settlement costs dramatically, last-mile costs remain stubbornly high. The savings from cheaper rails (stablecoins, real-time payment networks) are often absorbed by FX spreads, local compliance costs, and agent commissions at the payout end. In 3 out of 4 corridors into Sub-Saharan Africa, costs still exceed 10%. Only 2 Sub-Saharan corridors were below the 3% SDG target in Q1 2025, compared to 25 corridors globally.

Agent Network Fragility

Cash-in/cash-out agent networks are critical for reaching unbanked populations, but they face structural challenges. Agents in rural areas often lack sufficient cash reserves for withdrawals, creating service disruptions at exactly the locations where alternatives are fewest. Sparse populations mean lower transaction volumes and weaker financial incentives for businesses to serve as agents. In 2025, agents cashed in $430 billion globally, but monthly active usage of mobile money accounts was only 25.7%, indicating that most registered accounts see infrequent use.

Regulatory Fragmentation

Last-mile payment providers must navigate different regulatory frameworks in every destination market. Licensing requirements, permitted payout methods, KYC/AML thresholds, and consumer protection rules vary by jurisdiction. For stablecoin-based last-mile solutions, regulatory uncertainty adds another layer: some markets have clear frameworks while others are still developing supervisory practices for digital assets. This fragmentation increases compliance costs and limits the speed at which new rails can be deployed.

Technology Access

Digital last-mile solutions require recipients to have smartphones, data connectivity, or at minimum feature phones with USSD capability. While USSD-based transactions captured 63.5% of mobile money volume in Africa in 2024 (working on basic 2G phones), more advanced stablecoin and wallet-based solutions require smartphones and internet access that remain out of reach for the poorest populations.
