Two rails, two different jobs
ACH (Automated Clearing House) is the primary domestic payment network in the United States. Created in the 1970s to replace paper checks, it powers payroll deposits, bill payments, tax refunds and transfers between US bank accounts. SWIFT (Society for Worldwide Interbank Financial Telecommunication), founded in 1973, is a global messaging network used by more than 11,000 financial institutions to coordinate international transfers. A simple way to think about it:
- ACH is for moving dollars within the US banking system.
- SWIFT is for moving money between countries and banking systems.
How ACH works
When an ACH payment is sent:
- The sender initiates a payment.
- Their bank submits the instructions to the ACH network.
- The payment is processed in batches.
- The receiving bank credits the recipient’s account.
How SWIFT works
SWIFT itself does not move money, it sends messages between banks. When a SWIFT transfer is initiated:
- The sending bank creates a SWIFT instruction.
- One or more correspondent banks may take part.
- Each intermediary bank can deduct a fee.
- The receiving bank credits the final account.
Why ACH is usually better for receiving USD
For Brazilians receiving payments from US employers, clients, marketplaces or brokerages, ACH is often the better option. Instead of asking a payer to send an international Wire, you receive funds into a US account using domestic rails. The benefits:
- Lower costs.
- Faster settlement.
- No intermediary banks.
- No Wire fees.
- A familiar payment method for US companies.
Why SWIFT is more expensive
International Wires often stack several layers of cost:
- Wire fees.
- Correspondent bank fees.
- Receiving bank fees.
- Foreign-exchange spreads.
- Possible IOF on traditional remittance flows (up to 3.5% sending abroad, per Decreto 12.499/2025).
What this means for receiving USD in Brazil
If your income comes from the United States, the most efficient setup is usually:
- Receive dollars into a US account via ACH, RTP or a domestic Wire.
- Hold the dollars in USD.
- Convert or transfer the funds when you need to.
When SWIFT still makes sense
SWIFT remains essential in many situations:
- Large institutional transfers.
- International corporate treasury operations.
- Payments where the counterparty only accepts bank Wires.
- Certain countries and currencies not served by other rails.
The future is not ACH or SWIFT
Modern payment infrastructure increasingly combines several rails. A typical Ruvo user might:
- Receive USD via ACH.
- Receive urgent payments via RTP.
- Receive a brokerage payout via Wire.
- Move funds using stablecoin settlement.
- Withdraw to Brazil via Pix.
