Top 20 global payment corridors, and how Spondula fixes them

Sixty-three billion dollars, and most of it still waits three days

Maria works a double shift at a hospital in San Antonio. On Friday afternoon she opens her phone and sends money to her mother in Guadalajara — the same amount she sends every month, the same corridor she has used for years. The money enters a processing queue. Saturday: pending. Sunday: pending. By Tuesday morning it lands, four days after she pressed send, on a route that a text message would cover in a fraction of a second.

The USA-to-Mexico corridor is the largest single remittance flow in the world. It moved $63.3 billion in 2024 (BBVA Research, 2024). It is also one of the cheaper corridors — digitised early, with competition that has pushed costs toward 3% on some sends. Most of the other nineteen corridors in this guide are not that fortunate. They carry similar stories and worse numbers.

The global average cost of sending USD 200 across borders was 6.49% in Q1 2025 — more than double the 3% target the United Nations has set for 2030.

This guide names all twenty corridors, explains what makes each one slow or expensive, and then shows what every one of them has in common — and how Spondula's approach, anchored around the Shandle, changes the equation for senders on any of these routes.

From North America: five corridors carrying billions south and east

The United States and Canada together send more remittances than any other group of countries in the world. Five of the twenty corridors here originate in North America, and they span the Americas and the Pacific with different cost profiles and different friction points.

1. USA → Mexico. The world's largest single remittance corridor, moving $63.3 billion in 2024 (BBVA Research, 2024). Families in Texas, California, and Illinois send money south to support parents, siblings, and children. The good news: digital competition has driven costs down toward 3% on some sends — among the lowest of any major corridor globally. The friction that remains sits in the timing: a Friday-evening send still routes through a processing queue that doesn't clear until the next business day, meaning a weekend send can take until Tuesday.

2. USA → El Salvador. Remittances represent more than 20% of El Salvador's GDP — one of the highest ratios anywhere in the world. A Salvadoran worker in Virginia who sends home on a Thursday often sees the money land Monday. US bank cut-off times and the lack of same-day processing for international sends mean that Thursday evenings and Fridays fall outside the settlement window entirely. Costs on this corridor range from 4% to 7% depending on the provider and whether the send is digital or cash-in.

3. USA → Guatemala. Guatemala received approximately $21 billion in remittances in 2023 (World Bank, Migration and Development Brief, 2024), the vast majority from the United States. A large proportion of Guatemalan senders are unbanked on the US side, which forces cash-in-to-cash-out transfers — the most expensive route through the system. Cash-in services add 2–4 percentage points above the digital-channel cost, and the cash-out network on the Guatemalan side introduces last-mile delays that no headline fee comparison captures.

4. USA → Dominican Republic. A large corridor serving one of the Caribbean's most remittance-dependent economies, with New York and New Jersey as the primary send points. Costs on digital channels average 4–6%, but the corridor routes through correspondent-bank relationships that add processing time even when the headline fee looks competitive. The money typically takes one to three days, and senders who send on Fridays can see the money sit over the weekend.

5. Canada → Philippines. Canada hosts one of the world's largest Filipino diaspora communities — healthcare workers, engineers, and skilled tradespeople who send home consistently. The corridor carries several billion dollars annually and is reasonably competitive among major operators, but settlement still runs one to two days. Cash-out infrastructure in provincial Philippines can add a further 24 hours to final delivery, and the last mile into rural communities often requires a visit to a cash-out agent rather than a direct account credit.

From the Gulf: where migrant workers power the world's biggest sends

The Gulf Cooperation Council economies — the UAE, Saudi Arabia, Kuwait, Bahrain, Oman, and Qatar — host tens of millions of migrant workers from South Asia, Southeast Asia, and East Africa. When those workers send home, the flows are enormous. Five of the twenty corridors in this guide originate in the Gulf, and they represent some of the world's most concentrated remittance volume alongside some of its most persistent cost friction.

6. UAE → India. One of the world's largest bilateral payment flows. Indian workers in Dubai, Abu Dhabi, and Sharjah — in construction, hospitality, finance, and retail — send home every month to families in Kerala, Punjab, and Uttar Pradesh. The corridor is well-served by digital operators and costs have compressed. But bank-to-bank transfers carry FX margins of 3–5% layered on top of headline fees, and the best rates require the sender to navigate between multiple apps rather than use the one they already have.

7. Saudi Arabia → India. Similar to UAE-India in scale and human story. The correspondent chain from a Saudi bank to a rural Indian account can pass through three institutions before delivery — each adding a processing day and a charge absorbed somewhere in the exchange rate rather than disclosed as a fee. Senders who compare headline prices across services often find the actual effective rate is higher than advertised once the FX margin is visible.

8. Saudi Arabia → Pakistan. Pakistan received $33 billion in remittances in 2024 (World Bank, Migration and Development Brief, 2024), with Saudi Arabia among the largest contributing corridors. Costs vary sharply: formal bank transfers can reach 5–7%, while mobile-wallet options have introduced competition without yet reaching all senders. Rural Pakistan relies heavily on cash-out agents who carry limited float, and delays at the last mile are a known problem even when the network send itself settles quickly.

9. UAE → Egypt. Egypt is one of the largest remittance recipients in the Middle East and North Africa region. The UAE-Egypt corridor carries heavy and consistent traffic, but Egypt's currency environment has periodically introduced a gap between the official exchange rate and the rate senders can actually access through formal channels — pushing some transfers toward informal arrangements that bypass the regulated system entirely. For senders who want a formal, traceable route, costs remain high and rate certainty low.

10. Kuwait → India. Kuwait's Indian worker population is smaller than the UAE's or Saudi Arabia's, but the corridor is steady and well-established. Bank-to-bank transfers average 4–5%, and Kuwait's remittance market has been slower to digitise than its Gulf neighbours. Many senders still use cash-in services through exchange houses, adding cost and a processing step that digital channels have only partially displaced in the past three years.

From Europe: diaspora networks and the old correspondent chain

Europe is the world's second-largest source of remittances after North America. The five European corridors here span the continent's largest diaspora communities — West Africa, South Asia, North Africa, and Turkey — and they collectively illustrate one of the most persistent problems in international money movement: the correspondent-banking chain that was built in a pre-internet era and has barely changed since.

11. UK → Nigeria. The most expensive corridor in this guide. Traditional bank transfers from the UK to Nigeria cost 8–10% of the send value (industry analyses referencing World Bank RPW corridor data, 2025). A sender wiring £200 from London to Lagos can lose £16–20 in fees and exchange-rate margin before the money arrives — typically three to five working days later. The weekend and UK bank holiday calendar can extend that to a week for Friday-evening sends. Nigeria is the single largest destination for UK-originating remittances, and despite fintech competition the costs on this corridor have been stubbornly slow to fall. It consistently ranks among the most expensive in Sub-Saharan Africa's already costly receiving region.

12. UK → India. A large and well-established corridor serving a British-Indian community spanning multiple generations. Digital providers have driven costs toward 3–4% for tech-savvy senders, but bank-to-bank transfers still average 6–7%, and one-to-three day settlement times persist across most channels. The corridor is competitive but not as efficient as its volume would suggest — the presence of many operators has compressed fee disclosure without always compressing the actual effective cost.

13. UK → Pakistan. The UK-Pakistan corridor is high-volume, driven by a large and well-established British-Pakistani community. Costs are broadly similar to UK-India, but Pakistan's currency volatility means the effective rate a sender sees on any given day can vary by a percentage point or more. Comparing providers is harder than it should be, and the rate uncertainty discourages switching even when a better option exists.
