faq:
  - q: "What is a payment corridor?"
    a: "A payment corridor is the route money takes from one country and currency to another, for example US dollars in the United States to Brazilian reais in Brazil. It includes the rail that collects the money, the FX market that converts it, the rail that delivers it, and the rules on both ends. Each corridor has its own cost and speed."
  - q: "Is a payment corridor the same as a currency pair?"
    a: "No. A currency pair is only the FX part. A corridor adds direction, the countries, the local rails, and the compliance rules. USD to BRL over Pix and USD to BRL over TED share a currency pair but settle on different rails with different timing. Sending from Brazil to the US is a different corridor again, with its own price."
  - q: "Why is sending money to Mexico cheaper than to other countries?"
    a: "The US to Mexico corridor is one of the largest in the world, so it has deep FX liquidity, many competing providers, and an instant local rail in SPEI. The World Bank recorded Mexico as the cheapest G20 receiving market in Q3 2025, at 4.53% of a $200 transfer. Depth and competition push prices down."
  - q: "Does direction matter in a payment corridor?"
    a: "Yes. Sending to a country and sending from it are separate corridors with separate prices. In the World Bank's Q3 2025 data, sending $200 to Brazil cost 5.38% on average, while sending $200 from Brazil cost 11.91%. Outbound rules, FX controls, and fewer providers on one side all show up in the price."
  - q: "How do stablecoins change a payment corridor?"
    a: "They replace the correspondent banking chain in the middle with a dollar token that settles on a blockchain in minutes. The corridor becomes two legs: money in, converted to a stablecoin, and stablecoin out, converted to local currency on a local rail. The receiving market's liquidity still sets most of the price, which is why you compare quotes per corridor."

A payment corridor is the route money takes between two countries and two currencies, for example US dollars in the United States to Brazilian reais in Brazil. Each corridor has its own rails, FX market, rules, and costs. That's why the same provider can price USD to MXN tighter than USD to COP, and why every quote is a corridor price.

Corridors are the unit everyone in cross-border payments thinks in, from the World Bank to the treasury team picking a payout provider. If you know what one is made of, you can read a quote and tell which part of the price comes from where.

**Key takeaways**

- A corridor is direction plus two countries plus two currencies plus the rails on each end.
- Corridors cost different amounts because liquidity, competition, rails, and rules differ.
- Direction matters: sending to Brazil and sending from Brazil are two different corridors.
- Stablecoins split a corridor into an on-ramp leg and an off-ramp leg, and the receiving market sets most of the price.
- Compare providers corridor by corridor, at the same moment, on the amount that lands.

## What is a payment corridor?

A payment corridor is a specific sending country and currency paired with a specific receiving country and currency. US to Mexico is a corridor. Mexico to the US is a different one.

The term comes from remittances. The World Bank's Remittance Prices Worldwide database tracks costs corridor by corridor, across 48 sending countries, because a global average hides huge gaps between routes ([World Bank RPW, Issue 54](https://remittanceprices.worldbank.org/sites/default/files/2026-04/RPW_main_report_and_annex_Q325.pdf)).

Business payments use the same idea. A payout platform that "covers Latin America" really covers a list of corridors, each with its own price, speed, and paperwork. If you're new to reading the price itself, start with [how to read an FX quote](/resources/more/how-to-read-an-fx-quote).

## What is a corridor made of?

Five parts. Each one can add cost or delay.

| Part | Example: US dollars to Brazil | What it changes |
| --- | --- | --- |
| Collection rail | ACH, wire, or a stablecoin deposit | How fast money enters the system |
| FX market | USD/BRL | The spread you pay to convert |
| Delivery rail | Pix, PIX Safe, or TED | How fast money lands, and on which days |
| Rules | KYC/KYB, sanctions, local FX regulation | Documents, holds, limits |
| Liquidity | Who holds reais ready to pay out | Whether a rate can be held, and at what size |

The FX market gets most of the attention, but the delivery rail matters just as much. Pix runs 24/7 and settles instantly. TED follows business days. Same currency pair, different corridor experience. [Stablecoins plus local rails in Latin America](/resources/more/stablecoins-local-rails-latin-america) walks through each country's rails.

## Why do some corridors cost more than others?

Because depth, competition, and rules vary by route. A busy corridor with many providers and a liquid currency gets cheap. A thin one stays expensive.

The World Bank's Q3 2025 numbers for a $200 transfer show the spread:

| Corridor (Q3 2025) | Average cost of sending $200 |
| --- | --- |
| To Mexico (cheapest G20 receiving market) | 4.53% |
| To Brazil | 5.38% |
| To China (most expensive G20 receiving market) | 7.31% |
| From the United States | 5.04% |
| From Germany (cheapest G20 sending market) | 4.49% |
| From Brazil | 11.91% |

Source: [World Bank Remittance Prices Worldwide, Issue 54](https://remittanceprices.worldbank.org/sites/default/files/2026-04/RPW_main_report_and_annex_Q325.pdf). The same report says 83% of corridors now average under 5%, up from 17% in 2009.

Look at Brazil. Receiving into Brazil costs 5.38%. Sending out of Brazil costs 11.91%. Same country, same currency, opposite direction, more than double the price.

The FX market behind each corridor differs in size too. In the BIS Triennial Survey for April 2025, USD/MXN traded $140 billion a day and USD/BRL $86 billion, while the Colombian peso was 0.2% of global turnover ([BIS Triennial Survey 2025](https://www.bis.org/publications/202509-commentary-otc-derivatives.pdf), Tables 4 and 5).

The World Bank figures are consumer remittance prices on small amounts. Business payouts are larger, so the percentage is lower, but the drivers are the same. [How much cross-border payments cost in 2026](/resources/more/cross-border-payment-costs-2026) breaks down where the money goes.

The G20 has set corridor-level goals too. The Financial Stability Board's targets call for retail cross-border payments to average no more than 1% by end-2027, with no corridor above 3%, and for remittances to average 3% by 2030, with no corridor above 5% ([FSB](https://www.fsb.org/work-of-the-fsb/financial-innovation-and-structural-change/cross-border-payments/g20-targets-for-enhancing-cross-border-payments-2/)). The corridor cap exists because averages hide the expensive routes.

## Is a corridor the same as a currency pair?

No. A currency pair is only the FX part of a corridor.

USD to EUR into Germany and USD to EUR into Spain share a pair and a rail (SEPA), so they behave almost the same. USD to BRL over Pix and USD to BRL over TED share a pair but not a rail, so timing differs. And some currencies can't be delivered offshore at all, so the corridor has to end with a local partner inside the country. [What a non-deliverable currency is](/resources/more/non-deliverable-currencies-stablecoin-payouts) covers BRL, COP, and ARS.

## How does corridor liquidity set the rate you get?

The rate on your quote is the receiving market's price, plus the provider's margin, at that moment.

Liquidity is what decides how good that price can be. A provider with local currency ready to pay out, or a market maker willing to sell it at size, can quote a firm rate and hold it for minutes. A provider that has to go find reais after you confirm can't. [What a liquidity market is in cross-border payments](/resources/more/what-is-a-liquidity-market-cross-border-payments) explains the mechanics, and [choosing a liquidity partner for LatAm payouts](/resources/more/latam-payout-liquidity-partner-pix-spei) covers what to ask.

Corridor size shows up in three places:

1. **Spread.** Deep corridors quote tighter rates.
2. **Quote window.** Deep corridors can hold a rate longer.
3. **Size.** Deep corridors keep the same rate on a $250,000 payout as on a $5,000 one.

## How do stablecoins change a corridor?

They replace the middle of the corridor. In a bank wire, money hops through correspondent banks, each holding pre-funded balances and taking a fee. With stablecoins, the dollar leg settles on a blockchain in minutes.

The corridor becomes two legs:

- **On-ramp leg:** local money in, converted to USDC or USDT.
- **Off-ramp leg:** USDC or USDT out, converted to local currency and paid on a local rail.

What doesn't change: the receiving market still sets most of the price. A stablecoin doesn't make Colombian pesos more liquid. It removes the correspondent hops and the pre-funding, and leaves you paying the local FX market for the last mile. [Why cross-border payments are slow](/resources/more/why-are-cross-border-payments-slow) covers what the middle used to cost.

## Illustrative example: how do two corridors compare on one payout?

Illustrative example. A company sends the equivalent of $10,000 USDC to a supplier in Brazil and another $10,000 to one in Colombia. The rates below are made up to show the math. They are not BlindPay prices.

| Line | USD to BRL | USD to COP |
| --- | --- | --- |
| Market rate | 5.4000 BRL per USDC | 4,000 COP per USDC |
| Quoted rate after margin | 5.3730 BRL per USDC | 3,976 COP per USDC |
| Margin in the rate | (5.4000 - 5.3730) / 5.4000 = 0.50% | (4,000 - 3,976) / 4,000 = 0.60% |
| Flat fee | 2 USDC | 2 USDC |
| Amount converted | 9,998 USDC | 9,998 USDC |
| Recipient receives | 9,998 x 5.3730 = R$ 53,719.25 | 9,998 x 3,976 = COP 39,752,048 |

The flat fee is identical, but the corridor margin is not. On these numbers the Colombia corridor costs 0.10 percentage points more, or about $10 on every $10,000. Across $500,000 a month that's $500, for no reason other than the corridor.

## How should you compare providers across corridors?

Quote each corridor separately, at the same moment, for the same amount, and compare the amount that lands. Averages across a "region" tell you nothing.

On a BlindPay payout quote, `commercial_quotation` is the market rate and `blindpay_quotation` is the rate after BlindPay's margin, next to `sender_amount`, `receiver_amount`, and the fee lines ([payout quotes](/docs/payout-quotes)). That makes the corridor margin visible on every quote. BlindPay combines a monthly plan with per-transaction fees that vary by rail and network and are disclosed in the live quote before execute.

BlindPay pays out on Pix, PIX Safe, and TED in Brazil, SPEI in Mexico, ACH Colombia, Transfers 3.0 in Argentina, SEPA in the euro zone, ACH, wire, and RTP in the US, and SWIFT for international wires ([bank accounts](/docs/bank-accounts)). Each one is a corridor you can quote on its own. [Settlement times by country and rail](/resources/more/stablecoin-payout-settlement-times) lists how fast each one lands.

## What to do next

Pick the two corridors you pay most and request a payout quote for each on a development instance, same amount, same minute. Compare `commercial_quotation` with `blindpay_quotation` on both. The [payout quotes docs](/docs/payout-quotes) have the request body.
